EXECUTIVE SUMMARY

This report looks into the opportunity to expand the wind power generation capacity around the Qartli wind farm (to be referred to as Qartli1), a 20MW operational wind farm situated in the Shida Kartli region of Georgia, near the town of Gori.

Qartli1, is a 20.7 MW wind farm, whose six Vestas 3.45 MW wind turbine generators have been operational since 2017. The plant, built by Vestas and China Nuclear Construction Ltd, with Mott Macdonald as supervisor, has seen capacity factors of 48-49% during its first years of operation. Its owner and developer, Georgia Energy Development Fund, has just successfully sold the project company in a public auction.

The available wind resource, as demonstrated by Qartli1’s 36-month operational performance and 30+ months of anemometer wind measurements, is ample enough to justify a feasible wind farm expansion in the adjacent area, for technical as well as financial considerations.

Ridgeline Industrial, www.ridgeline-industrial.ro, a Romanian energy consultancy, has undertaken this report in order to analyze the feasibility of expanding the Qartli1 Wind Farm in Georgia. The study is partly funded by RoAID, the Romanian Agency for International Development Cooperation. In 2018, Ridgeline Industrial has done a study called “A Review of the Georgian Energy Sector and Development Opportunities - Wind Energy Potential in Georgia”, which was funded with a RoAID grant. The study was presented to Her Excellency Natia Turnava, the Deputy Minister of Economy and Sustainable Development of Georgia, on 27-Feb-2019 by Mr. Cǎtǎlin Harnagea, RoAID’s Director General. Representatives of the Georgian Ministry of Economy and Sustainable Development, the Georgian Energy Development Fund, the Georgian National Energy and Water Supply Regulatory Commission, and other Georgian energy sector stakeholders joined Deputy Minister Turnava in the meeting.

The study, available for review on Ridgeline Industrial’s website, focused on ways to increase the share of wind energy in the Georgian energy mix, and was commissioned by RoAid to Ridgeline Industrial, in response to the Georgian energy sector stakeholders’ interest to increase energy security.

The next steps recommended included between others, an in-depth feasibility study for the expansion of the Qartli wind farm by 100 MW, and assistance with the implementation of a platform for transparent market monitoring and trading, for both natural gas and electricity.

The Georgian party expressed keen interest in undertaking further detailed analysis of advancing financially sustainable wind power projects in Georgia, as well as of market-based mechanisms to support renewable energy development. A letter sent by the Ministry of Economy and Sustainable Development of Georgia in April 2019, to RoAID, further illustrated this request, and Ridgeline Industrial was retained to conduct this follow-on report, the expansion of the existing wind-farm, as a concrete expression of the conclusions enunciated in the initial study.

The Expansion of the Qartli Wind Farm – A Study of Opportunity

7

This report should constitute a useful document to attract investment in the expansion of the wind farm, whether from the Georgian Energy Development Fund or outside investors. The Georgian Energy Development Fund and its partners, as the main beneficiaries of this report, can take the conclusions resulted from the detailed wind resource and financial analyses illustrated here, and attract outside investment if they so wish, in order to develop approximately 100 MW in additional wind farm capacity.

Our assessment is that subject to an update of the existing Environmental Impact Assessment (Qartli 1), a further road survey, the development of a fully bankable financial model, and the selection of turbine supply and balance of plant contractors, the project should be ready to build within the next 6-9 months.

We recommend the expansion in phases of 10/20 MW in 2021, 20MW in 2022, and 50MW in 2023, as this schedule would fit with GES, the grid operator’s interconnection constraints at the nearby 110 kV sub-station in Gori.

The 10, 20, and 50 MW sections will address in detail wind farm production figures, capital expenditure, operational expenses, as well as a full array of financial indicators. We see project returns at 9-12%, and levered equity returns at 19-23%.

It is our understanding that newly developed wind farm projects will sign power purchase agreements with ESCO (the sole electricity market operator, 100% owned by the Government of Georgia). The PPA will have duration of ten years at USD 60/MWh, with no indexation.

Qartli1 was partly financed by the EBRD, with a 10-year non-recourse project finance loan, and as result we believe a similar contractual structure will be available for future projects. We understand that the EBRD has arranged a USD 22 million syndicated loan to the project company, Qartli Windfarm LLC, in 2016, for the development, construction and operation of the wind farm. The Bank itself has provided a USD 10m tranche (the A loan), and the remaining USD 12m B loan has been syndicated to the Dutch impact investors OIKOCREDIT, Ecumenical Development Co-operative Society U.A; Triodos Groenfonds N.V.; and the Luxembourg-based Green for Growth Fund (GGF). Each took a USD 4m share.

We assume the permitting process has been partly completed and could be expedited given the immediate adjacency to the Qartli 1 wind farm.

The 10, 20 and 50 MW-range projects were simulated using the latest generation GE “Cypress” (5.3MW), Nordex (4.5 MW), Siemens Gamesa (4.1MW), Vestas (4.2MW) and Enercon (5MW) wind turbine generators, while decommissioned GE 1.5 MW WTGs were considered for a 2nd hand option. Ruisi wind farm, a project developed by Georgia Energy Development Fund with a partner, has identified 8-9 turbine locations adjacent to Qartli1, and this is where the GE 1.5MW turbines are considered.

The Wind Assessment Report in Annex 1 presents the detailed calculations, while Annexes 2 and 3 illustrate annual energy calculations and wind turbine generator siting for the 10 and 20 MW options. The 50MW option is analyzed financially based on estimated production values, with a good degree of confidence.

Annex 4 illustrates Qartli1, as the reference wind farm, for annual energy calculations and siting.

Detailed capital expenditure calculations and operation and maintenance can be found in Annexes 5 and 6, while the financial spreadsheets behind the selected financial model figures are presented in Annex 7.

GENERAL CONSIDERATIONS FOR WIND TURBINE GENERATOR SUPPLY

Wind turbine generator (WTG) suppliers will generally make offers specific to the selected sites, which include supply of wind turbine generators, associated equipment, and related services.

A standard offer usually refers to the delivery, unloading, installation and commissioning of the wind turbine generator. The basic offer will include the wind turbine generator model specifications, electrical system specifications; internal step-up transformers are usually included with the equipment.

Other features such as manufacturer specific monitoring systems, nacelle logos, tower markings, basic aviation lights, access equipment such as service elevators, related safety features are also usually included.

Examples of WTG ancillary equipment: n Wind SCADA (Standard Supervisory Control and Data Acquisition) - the supervisory

control and data management system for the wind farm (also see the balance of plant considerations section)

n Country Specific Features such as O&M Manuals and SCADA interfaces, various certifications

Option examples to turbine supply contracts: n Reactive power features - these may allow the turbine to generate and consume reactive

power without active power generation n Met mast interfaces n Ice detection devices n Training

GENERAL CONSIDERATIONS FOR WIND FARM RELATED BALANCE OF PLANT WORKS

Balance of plant (BoP) is the cost of all infrastructural and facilities of a wind-farm with an exception of the turbine and all its elements. The balance of plant therefore mainly comprises of the following items:

n Crane pads/ Hard standings n Foundations n Substation Civil and Electrical including Transformers n Road upgrades and Construction n Cabling to substation and Grid including SCADA

CRANE PADS / HARD STANDINGS

Crane Pads are prepared on each turbine location so as to facilitate and accommodate the heavy lifting operations of tower, turbine and blade installation. The type of ground conditions will determine how intensive or costly the pad construction is going to be. Pads are rated by their carrying capacity, which is the amount of load they can withstand. Typical ratings will range between 200KN/m2 to 500KN/m2 mainly to provide a strong solid base for heavy cranes to do the lifting the tower and wind turbine generator. Crane Pads are usually located adjacent to the turbine foundations to facilitate turbine components lifting during turbine erection and future maintenance or repairs. These are usually unpaved, compacted layers of crushed rock.

FOUNDATIONS

Foundations are the key and critical BoP element in terms of both cost and materials for any wind farm development project. Every turbine manufacturer has its own preferred foundation type but the most commonly used are the gravity and pile-reinforced types. A turbine foundation can be described as a mass of concrete and reinforcement cast accurately to connect to the turbine tower. The basic components of a foundation are:

n Concrete: Gravel, sand, cement; n Reinforcement: Steel; n Can/Basket Assembly;

The foundation should be strong enough to provide the required base support for the rest of the structures above it. Turbine foundations have generally been designed to be founded on the weathered schist or dense gravel with a minimum allowable bearing capacity of 500 KPa for a 2.3MW wind turbine. The quality of the foundation is of the utmost importance to the wind turbine structure. The design specifications have to be strictly adhered to. The pouring of concrete has to be done carefully to prevent surface and thermal cracking to ensure final foundation is of the required quality and standard.

11

SUBSTATION CIVIL AND ELECTRICAL

Substation Civil

This encompasses the building housing the other electrical, safety and operational equipment. The building is usually constructed to the required acceptable standards, as determined by the electrical providers and legislation. All elements of the substation structure from foundations, plumbing for cables, walls and roofs are usually designed and constructed as per the required specifications and quality requirements. The substation building usually consists of a single story building with shallow foundations (if ground conditions permit). The size could be around 10m by 25m for a 20MW wind farm, plus external transformer area, which requires plinths for the equipment and an earthed fencing. The building may also be facilitated with toilets, sink and possibly shower facilities and so aseptic tank may be required.

Substation Electricals

The electrical components found in the substation are mainly for facilitation of the operational aspects of the wind-farm. This usually includes components such as switchgear, power protection systems and the electric meter. A transformer may also be part of the substation components to enable step up or step down of the power output. The size of these elements is dependent on the wind-farm power capacity.

ROAD UPGRADES AND CONSTRUCTION

Roads are essential in providing access to the wind farm and specifically to the turbine location sites within the wind farm. During construction, access is required to move in material and equipment to where they are required within the site. Roads are also useful during the lifetime of the wind-farm as they are used for operational maintenance purposes. It is necessary to construct site access roads, which are strong and durable enough to withstand the heavy traffic during construction. The roads should be able to provide safe and reliable access for the rest of the lifetime of the wind farm in all weather conditions. These are usually unpaved roads made of compacted layers of crushed rock, gravel, and high-density polyethelene geogrid layer. The roads of a wind-farm may be classified into two, namely:

Site access roads

These connect the wind-farm site to the nearest public road network. The length of which depends on the closest accessible public road network beyond the wind farm. In Scotland, this may often involve the upgrade of forestry or farmers track. The upgrade exercise may comprise reconstructing several kilometers of an existing road, re-building a bridge, or more commonly moving a few lamp posts.


12

Wind-farm network roads

These are the roads, which connect each turbine location to other elements of BoP within the wind-farm. They are mainly used for access and transport of materials and equipment around the site, between the turbine locations, substation, and meteorological mast. In most wind farms the road length within the wind farm is normally between 0.4 and 0.5 km per turbine, but this length may vary depending on the characteristics of the terrain.

All roads have to be constructed prior to the erection of turbines. In some cases there may exist some roads, which would require some upgrading in order to meet the standard needed for trafficking of the turbine and other wind-farm components. The general requirements for all types of roads are 4.5 meters width but slightly wider at turns and a load bearing capacity to withstand the heaviest of the wind-farm components to be trafficked through.

CABLING TO SUBSTATION AND GRID Cabling to Substation

The power generated on each turbine is transmitted to the wind farm substation. This is done by means of a cable network connecting every turbine with the substation at a medium voltage (11-36kV). The cables can be overhead but underground trenched cabling is the most common. The overall length of cable depends on the distance from the turbines to the substation and the network layout. Normally the underground cables are buried roadside as this makes installation and future maintenance simpler. As a rule of thumb the length of cable per turbine is approximated to be 0.4 to 0.5 km.

Cabling to Grid

This cabling connects the wind farm substation to the closest distribution or transmission line. It can be underground but overhead cabling is the most common. Although the underground option is mostly preferred due to its lack of visual impact, the overhead option is more economic. The length of the line depends on the distance from the wind-farm substation to the point of connection on the main grid. The cable characteristics will depend on the total wind farm rated power and the transmission voltage on the downstream of the wind farm substation.

Point of Connection

This includes the commissioning of all the components necessary to complete the connection to the distribution network, including hardware, such as switches, reinforcements, supports including protection and measuring elements. The functions of the different systems at the point

13

of connection may be classified contestable and non-contestable. The non-contestable affect the security of the distribution line and must be carried out by the distribution network operator in the area. The characteristics and cost will depend on the power capacity of the connection and the singularities of the distribution network in the area.

SCADA

Supervisory Control And Data Acquisition (SCADA) is an industrial control system, which enables users to monitor and control remote operations of wind turbines and other associated systems in real time. Users can access accurate real-time information including live weather and meteorological updates as well as fully configurable Key Performance Indicators (KPIs). Comparison of past production patterns against historical current and live information helps in fine-tuning to keep equipment at optimal efficiency. Some windfarm SCADA systems provide users with rich 2D and 3D visualizations and reports with integrated real-time and historical geographical terrain maps and graphics. Turbine information including wind speed, wind direction, power blade position, temperature and vibration can be accessed on real-time. The cost of a SCADA system will depend on the complexity of the desired package.

TRANSFORMERS

Most of the wind turbines generate electricity at a low voltage level from 600 to 1000 (V). In order to reduce the losses associated with electricity transmission, each wind turbine is equipped with a transformer to step up the voltage. Usually these transformers are situated at the base of the wind turbine as this makes it more accessible for operational monitoring and maintenance works. Having the transformer located in the nacelle, very close to the generator, has the advantage of reducing transmission losses as compared to the base location. If the transformers are supplied by the turbine manufacturer, they won’t be considered as part of BoP. The transformer may also be positioned inside or adjacent to the tower and therefore it is treated as one of the turbine components. The characteristics of each transformer are fixed by the rated power generated by the turbine, the voltage level and the transformation ratio.

MISCELLANEOUS COSTS

Overheads and others

This is a classification of other supplementary but necessary facilities or services, which form an essential part of BoP but cannot be particularly categorized in to any of the main items above. They are herewith categorized under the class of overheads and others as described below.


14

Borrow Pit

This is a small, on-site quarry, typically used to obtain crushed rock for the construction of roads and crane pads. Not always feasible if rock is not present or suitable, and not always allowed by planning, it can result in savings on road stone costs if a borrow pit is used.

Site-wide drainage

This may be considered as a separate cost, or could be included in the cost of the various ground works such as tracks and crane pads.

Ground Investigation

This includes boreholes, trial pits, soil samples and laboratory tests etc. Usually this is done at each wind turbine location, the substation and along the access roads prior to award of the BoP contract. Sometimes additional ground investigation work may be required during the construction phase if the ground conditions are particularly complex.

Ground Risk

There is always a risk of cost or delay relating to the ground characteristics because it is not feasible to investigate the ground in every part of the site before construction commences. Usually the contractor is expected to take the risk relating to the ground by assigning a price to it. The cost price of this risk will depend on local ground conditions regarding soil type, location of bedrock or peat-bogs for example, plus the cost of any groundwork associated with making the ground suitable for building on.

Transportation

Transport of BoP construction materials is usually included in the price of materials. The price of transport will mainly depend on the distance and remoteness of the location, local fuel costs and the types of transport being utilized for delivery.

Topographic Survey

This is usually required before and after the all ground works. The post construction topographical survey usually forms part of the BoP works but the initial one is sometimes omitted.

15

Design Costs

Wind-farms are typically let as “design and build”, otherwise known as EPC-engineer, procure and construct contracts. The outline design comprises largely of the site layout, which is usually completed at the pre-tender stage. All detailed design calculations and drawings are the responsibility of the BoP contractor.

Site Facilities

The BoP contractor is usually responsible for providing toilets, offices, and other requirements for the site as a whole for the duration of site construction.

Project Management

Some wind farms are built as two contracts: BoP and Turbine Supplier Agreement. Some are constructed under one wrapped contract, with either the turbine supplier or the BoP contractor acting as the lead party and taking full responsibility for the coordination and delivery of the works. The wrapped contract is lower risk and less work for the client, but consequently more expensive. The BoP cost will depend on the option taken.

Meteorological mast

Not all wind farms have a meteorological mast, and the responsibility for the design and construction of the foundation/crane pad and the mast may or may not be the BoP contractor’s responsibility.

10 MW VERSION - A REVIEW

The Qartli Wind Farm, situated in the Gori region of Georgia, is suitable for a 10MW increase of capacity. The annual energy production assessments are illustrated in the “Summary Production Results” table, Figure A1, and show P75 (capacity factors: 40% - 52%) and P90 figures (capacity factors: 38%-49%). P75 indicates that there is a probability of 25% that the indicated level of annual energy production will not be reached, while P90 indicates a probability of 10% for the same issue. Banks will usually use P75 and P90 figures.

The annual energy production for the various wind turbine configurations is the result of the detailed Wind Assessment Report, in Annex 1, with P40 to P90 figures analyzed. A summary of the figures can be found in Annex 2, with detailed annual energy calculations and optimal locations for the wind turbine generators.

Our assessment is that subject to an update of the existing Environmental Impact Assessment (Qartli 1) and a further road survey, a 10MW expansion should be ready to build within the next

17

6-9 months. The construction should take about 12 months, subject to the availability of the wind turbine generators. We assume the permitting process has been partly completed and could be expedited given the immediate adjacency to the Qartli 1 wind farm.

A wind farm in the 10 MW range, using the latest generation wind turbines, will cost between USD 15m and USD 19m. The used turbine scenario will cost USD 10m. We have simulated 10 MW-range projects using new generation GE (5.3MW), Nordex (4.5 MW), Siemens Gamesa (4.1MW), Vestas (4.2MW) and Enercon (5MW) wind turbine generators, while for the 2nd hand option, GE 1.5 MW WTGs were considered. We believe the figures should cover the cost of building the wind farm, while recognizing that the selected manufacturer and general contractor will need to submit a detailed commercial offer specific to the selected site. Higher capacity wind turbines configurations, which will require 2 wind turbine generators, will be more expensive per WTG, but will require less outlay on foundations and electrical cabling. Please refer to Figure A2, which illustrates the various CAPEX estimates.

In terms of O&M costs, we see a range between USD 600 000 and USD 800 000 annually, considering standard Full Service Agreements; two-turbine configurations will be less costly to maintain than three-turbine configurations. The 7-turbine configuration using second-hand 1.5 MW turbines will be the more expensive one. Please refer to the Figure A3 below for various OPEX estimates.

Figure A3 - Opex Summary

In terms of financial results, we have illustrated an array of figures using P75 and P90 production values in two separated tables (Figures A4 and A5). The 30-months+ of the current Qartli 1 20 MW wind farm operational performance indicate that P75 figures are closer to the actual performance.

We see project IRRs varying from 9% to 11% in the P75 scenario, and 7% to 10% in the P90 scenario. [Levered] Equity IRRs vary from 18% to 21%, and 15-19% respectively. The minimum debt cover service ration (DSCR) varies from 1.67 to 1.94, and 1.5 to 1.8 respectively. The average debt cover service ratio ranges from 1.74 to 2, and 1.6 to 1.9 respectively. We have assumed conservative 50/50 debt-equity leverage, with 10-year no-recourse project finance at 6% (USD). As the indication is that a 10-year PPA at USD 60/MWh will be available, we have modeled the debt tenor to match the PPA duration, similar to the existing EBRD loan tenor in the Qartli 1 wind farm project. Loan Life Cover Ratios and Project Life Cover Ratios, as well as other indicators are also illustrated in the two tables.

Our conclusion is that a larger capacity and efficient wind turbine configuration, which will maximize the production during the first 10 years of operations, when the PPA is available, will render the better yield, and should be preferred.

In terms of O&M costs, we see a range between USD 900 000 and USD 1m annually, considering standard Full Service Agreements; four-turbine configurations will be less costly to maintain than five-turbine configurations. The 9-turbine configuration using second-hand 1.5 MW turbines will be the more expensive one (per Mwh). Please refer to the Figure B3 below for various OPEX estimates.

Figure B3 - Opex Summary

In terms of financial results, we have illustrated an array of figures using P75 and P90 production values in two separated tables (Figures B4 and B5). The 30-months+ of the current Qartli 1 20 MW wind farm operational performance indicate that P75 figures are closer to the actual performance.

We see project IRRs varying from 10% to 13% in the P75 scenario, and 8% to 12% in the P90 scenario. [Levered] Equity IRRs vary from 20% to 25%, and 17-23% respectively. The minimum debt cover service ration (DSCR) varies from 1.82 to 2.25, and 1.65 to 2.08 respectively. The average debt cover service ratio ranges from 1.9 to 2.3, and 1.72 to 2.13 respectively. We have assumed conservative 50/50 debt-equity leverage, with 10-year no-recourse project finance at 6% (USD). As the indication is that a 10-year PPA at USD 60/MWh will be available, we have modeled the debt tenor to match the PPA duration, similar to the existing EBRD loan tenor in the Qartli 1 wind farm project. Loan Life Cover Ratios and Project Life Cover Ratios, as well as other indicators are also illustrated in the two tables.

Our conclusion is that a larger capacity and efficient wind turbine configuration, which will maximize the production during the first 10 years of operations, when the PPA is available, will render the better yield, and should be preferred.

The Qartli Wind Farm, situated in the Gori region of Georgia, is suitable for a 50MW increase of capacity. The annual energy production assessments are illustrated in the “Summary Production Results” table, Figure C1, and show P75 (capacity factors: 45% - 50%) and P90 figures (capacity factors: 42%-46%). P75 indicates that there is a probability of 25% that the indicated level of annual energy production will not be reached, while P90 indicates a probability of 10% for the same issue. Banks will usually use P75 and P90 figures.

Figure C1 - 50MW Summary Production Results

The annual energy production for the various wind turbine configurations is an estimate based the result of the detailed Wind Assessment Report, in Annex 1, with P40 to P90 figures analyzed, for 10MW and 20MW layout options - our estimates in the 50MW layout scenario decrease the capacity factors by 1% to compensate for potential wake losses. No detailed layout and turbine siting were analyzed in our report for this 50MW option, but we deem our estimates to be reasonably detailed to justify a go-no-go decision on the development of such a wind farm.

Our assessment is that subject to an update of the existing Environmental Impact Assessment (Qartli 1) and a further road survey, a 50MW expansion could be ready to build within the next 12 months. The construction should take about 24 months, subject to the availability of the wind turbine generators. We assume the permitting process has been partly completed and could be expedited given the immediate adjacency to the Qartli 1 wind farm.

27

A wind farm in the 50 MW range, using the latest generation wind turbines, will cost between USD 62m and USD 65m. We have simulated 50 MW-range projects using new generation GE (5.3MW), Nordex (4.5 MW), Siemens Gamesa (4.1MW), Vestas (4.2MW) and Enercon (5MW) wind turbine generators. We believe the figures should cover the cost of building the wind farm, while recognizing that the selected manufacturer and general contractor will need to submit a detailed commercial offer specific to the selected site. Higher capacity wind turbines configurations, which will require less wind turbine generators, will be more expensive per WTG, but will require less outlay on foundations and electrical cabling. Please refer to Figure C2, which illustrates the various CAPEX estimates.

Introduction

The company Georgia Energy Development Fund (Georgia) wants to develop a new wind farm

and retained the services of Ridgeline Industrial (Romania) - Ridgeline Industrial's analysis is partly

funded by the Romanian Agency for International Development and Cooperation - RoAID - to

conduct a wind assessment report for the Qartli site, in Shida Kartli. This wind assessment report

was conducted using wind measurements from the site and MERRA long term data.

The objective of this report is to estimate the wind speed and compare the results in order to

develop a wind farm. The general method used in these situations is the extrapolation of the

meteorological data (mainly wind speed and wind direction) measured at different height in order

to find their correspondent at hub height. The results will then be used to estimate the produced

energy by each wind turbine generator.

In order to assess the wind speed and wind energy information regarding orography and

roughness are also needed. All these calculations and simulations were made using WindPro 3.2

software, recognized and approved worldwide. The initial phase for evaluating the wind potential

for a certain location is the analysis of the measured wind data in one or more points, as close as

possible to the location chosen for developing a wind farm.

The current report meets the wind assessment reports quality standards (version 1), standards

required by the Wind Experts Advisory Board from the German Wind Energy Association.

General aspects

The objective of this study is to estimate the wind speed from the site and to establish the

production values for the General Electric GE158-5.3MW, Nordex N149-4.5MW, Siemens SWT-

DD-4.1MW, Vestas V150-4.2MW, Enercon E147-5MW and General Electric GE1.5xle-1.5MW

turbine models in order to develop a wind farm. The general method used in these situations is

the extrapolation of the meteorological data (mainly wind speed and wind direction) measured at

different heights and in different locations in order to find out their correspondent at hub height.

The obtained data will then be used to forecast the energy produced by each turbine.

The wind resources from the site were calculated using the WIND ATLAS ANALYSIS APLICATION

PROGRAM (WAsP) method, developed by the Meteorology and Wind energy division from the

Riso Laboratory, Denmark. The present wind assessment report will analyze in detail the wind

regime from the beneficiary’s site, highlighting the energetic qualities. Based on this report the

client will be able to make a decision whether he will continue his investment at this location.

In order to calculate the speed and energy of the wind, orography and roughness data are

needed. All these calculations and simulations were made using the WindPro 3.2 software,

approved and recognized worldwide.

This software is based on WAsP software, which uses a numerical model (BZ model), to

extrapolate the climatic data of the considered region for a specific power curve, taking into

account the placement of the wind turbine generators and the way they are influenced by the

“wake effect”.

The first step in evaluating the possibility of using the wind potential of an area, is to process the

measured wind data in one or several points, as close as possible to the area where a future wind

farm will be situated. In order to conduct this study, wind data were measured for a period of 33

months at the Qartli Mast, on site.

Site description

Evaluation of the location’s specific factors that influence the energy calculation for the described

site was made using topographic maps (scale 1:25.000) and aerial photos. The location of the

wind park can be observed on the attached map. The coordinates of the reference point used to

define the wind potential [UTM WGS84 Zone 38 coordinates system] are stated in the following

table:

Table 1: Main point location, GPS coordinates

The area is located in center of Georgia, in the Shida Kartli region at 12km NV from Gori and

73km NV from Tbilisi.

Fig. 1: Qartli Site

Site visit

The site visit was carried out by the Ridgeline Industrial contracted staff in June 2019. The scope

of the visit was to verify the relevance of the information from the 1:25000 analysed maps,

determination of the roughness and verification of the measurment equipments from which data

will be used and if they were installed according to international standards, and also

determination of any possible obstacles near the park location that could cause disruptions or

influences to the wind turbine.

During the site visit, the tracking log was taken (Fig. 2) in order to visually represent the

information obtained on site in order to better evaluate the roughness and/or the influence of the

terrain over the site.

Ridgeline Industrial intended to also visit the meteorological masts, but this was not possible (the

met mast fell and was decommissioned), just the surrounding area was assessed.

Fig. 2: GPS tracklog from the site visit

The assessed site is located in the centre of Shida Kartli region, between the rivers Liakhvi to the

north and Kura to the south. The proposed development area is located on a plateau higher

than the surrounding landscape.

Landscape of the area

Panorama view of the surroundings

The region is mostly used for agriculture purposes. The agricultural areas are rarely interrupted by

trees outskirts, and there are small villages and some houses along the main roads. No major

obstacles were observed, except for the existing wind farm that has to be considered in the site

model. Also, in the area there are some power lines that cross site, they will be considered when

doing the layout.

The general roughness is registered in class 1.3, with values that may vary between 0.1m (grazing

areas, small agricultural crops) and 1.5 m (developed cereals).

Wind monitoring equipment

For a detailed analysis of local wind parameters, one measuring mast was used. The Qartli mast is

a 80m lattice tower with anemometers located at 30m, 60m, 78m and 80m and wind vanes

installed at 30m and 78m, the tower base is at 846m a.s.l.. The mast was installed by the client

team, and the sensors were provided by Thies Clima. The wind data validation was done by

Ridgeline Industrial contracted Team.

Calibration certificates were available for review, as well as the installation report.

Fig. 3: Qartli 80m Mast

Other data sources

Available for this site were long term data from NCAR, ERA5 and MERRA. The Ridgeline

Industrial team chose the MERRA 25+years data because it was the closest, it has good

availability and it had the best correlation.

Also available for this project was production data from a near by wind farm.

Data source Distance to Gori II Wind Farm

MERRA 5km QWF (existing wind

farm) 5km

Fig. 4: Other data sources

Roughness

The roughness factor defines terrain elements that influence the laminar air flow, and that is

situated at a relative distance from the reference point (meteo masts). In this case, using data

measured at the site visit, and analyzing the terrain in the area, a roughness map (Fig 5) for an

area of approximately 110 km2 has been created. The map was then used in WindPro 3.2 to

identify the way in which the wind profile is modified by its passing over those extents.

Fig. 5: Roughness Map

Orography

The orography of any region is a result of the action of internal (izostatic movements) and external

(climate) factors on the terrain. The Gori area is characterized by the existence of a plateau with a

medium altitude of 800m, bordered by an NW-SE oriented slope, with medium to high sloping

and a mountain range to the S.

Fig. 6: Height Contours Lines Map

Methodology

Measured wind parameters Gori Mast

Wind speed (mean and standard deviation) and wind direction were recorded during ~ 33

month’s period (August 2013 – February 2017) for the Gori Mast.

Recovery rate was 75.6% at the Gori Mast for all data and also some mast shading effects were

detected due to differences noticed between anemometers recording data at the same heights.

No history was provided about the maintenance of the met mast, but we can conclude that major

problems were caused by logger malfunctions.

The data logger from Gori Mast samples wind speed and direction once every second. These are

then combined into 10-minute averages, and along with the standard deviation for those 10-

minute periods, are put into a binary file.

Preliminary to data loading in WindPro 3.2 software, all wind data were subjected to a series of

tests and filters to weed out data that are faulty or corrupted.

Fig. 7: Wind profile and wind rose for the Gori Mast

The wind speeds as recorded at all the levels were reviewed.

Regarding monthly distribution of wind speed, the location is part from general Georgian climate,

with relative stabile mean wind speed distributions through the year.

Fig. 9: Monthly variation of speed

Uncertainty degree of measured wind data

No uncertainties reports were available for the data from the beneficiary, and for the data from

the MERRA location, and so the data gaps had to be analysed through personal investigation and

research methods. The total availability of the measured and filtered data from the Qartli Wind

Farm database, reach a value of 97%, which is a very good value.

Beside the data availability, the quality of the measured data depends on the anemometers

characteristics, the influences caused by the equipment installation and the terrain configuration.

In the following table uncertainties estimated for each analysis phase of the installed

anemometers are indicated as uncertainties in relation to the energy production calculation,

which is estimated as being 1.4 bigger than the wind speed uncertainties.

Uncertainty of the parts of the analysis and calculations

Wind statistic 5.96% Wind measurement 4.23%

Anemometer calibration 1.40%

Anemometer characteristics 1.50%

Installation equipment's influence 2.10%

Data recording 2.29% Availability 1.00% Recording frequency 0.50% Data recovery 2.00%

Terrain effects (turbulence, wind shear) 2.00%

Roughness and orography 1.65% Obstacles 0.50% Representation of the period 1.20%

Long term correlation (Index consistency, 100% level, transfer to the future)

2.00%

Site calibration (terrain modelling) 3.50% Wake model/ wind farm calculation 1.50% Integrity of the model (wind in hub height, transfer to the sites) 3.00% WTG power curve 7.00% Total uncertainty 9.79%

Total uncertainty is considered as being the square root of the sum of all individual factors.

Uncertainties can be evaluated in detail, as follows:

• The anemometer calibration uncertainty results directly from the calibration reports and

can be calculated with standard deviations of each recorded value. A simplified mean

value for the measured uncertainty was chosen.

• The anemometer characteristics uncertainty describes the link of a certain type of

anemometer with an ideal anemometer, regarding it’s behaviour due to wind profile

(cosine behaviour) and inertia (start up, overcoming the normal speed). First class Thies

type anemometer belongs to high class quality with high performances in turbulent wind

conditions. A small uncertainty is justified.

• The terrain influence is small, being indicated by the turbulence distribution between the

three heights. As the relief in the area can be characterised as easy tilted, this fact

shouldn’t lead to important vertical components of the wind vector and thus shouldn’t

influence the wind measurements.

MCP analysis

MCP is the abbreviation for Measure-Correlate-Predict techniques, which is widely in use for

establishing a long-term wind statistic using limited wind data from the current site and long-term

data from a more-or-less nearby site.

Because often the on-site measured wind parameters do not cover a long period in time, there is

a certain financial risk to estimate the turbine energy production for an entire park lifetime (mainly

25 years).

To cover a part from this risk, it is necessary to have the above mentioned long term corrected

wind data, obtained mainly after several statistical operations between the measured wind data

and another reference data that can be considered reliable for the same area. In this wind

resource assessment, the lack of reliable local meteorological data from meteo stations was

replaced with MERRA type data.

The MERRA dataset consists of u and v wind components at different pressure surfaces, surface

temperature data and surface heat flux. As we had mentioned early, only ten years long term

data from 80m height was used (1989 to 2016). In the following chart concurrent data only was

analysed.

Fig. 10: Measured wind data at Gori 80m mast and at MERRA point

There are several methods to obtain a long term corrected wind data for site location. WindPro

software can perform four MCP type analyses, their final result being dependent on several

factors. It remains at user’s attitude which method should be performed.

For the Gori wind statistic, the Ridgeline Industrial team correlated the 80m anemometer from

the mast with 50m level from MERRA, a satisfying correlation coefficient was obtained.

Establishing a decent match between the local measurement and long-term reference data

Ridgeline Industrial team proceeded to creating a relevant wind statistic using the Matrix method.

Fig. 11: Predicted Energy and Frequency for MERRA

This one is based on a wind speed (speed-up) and wind direction (wind veer) changes modelling

through a joint distribution that fits on wind speed bins and wind direction bins matrix.

The final results of this MCP calculation will be represented by a long-term corrected

meteorological data file, which will be used in an on-site WAsP analysis. According to results

from the long term analysis the difference between the measured data and the forecasted data

was obtained and lower wind speed were forecasted than the measured speeds.

WAsP analysis

For the analyzed area, the Ridgeline Industrial team chose, taking into consideration the

topography, the roughness and the size of the area, to consider it as one zone. The WASP object

and wind resources were calculated for this region. Production estimates for the 6 types of

turbines were also the scope of this report.

Fig. 12: WAsP regions

The WASP object used the wind statistics created from the Gori masts correlated with the MERRA

data using the Matrix method, calculated for the WAsP region.

Production analysis

The performance of a wind farm is additionally conditioned by the technical availability of the

installations and electrical losses. Since these values are depending on the contractual agreement

with the manufacturers and on the design of the grid connection. The user of this report has to

define the respective losses that also have to be considered. The calculated production figures

are equivalent to the production results of the wind turbine counters considering a 100 %

availability level, in order to obtain a real estimation of future production figures. It is necessary to

reduce the wind farm production by different kinds of losses. The following aspects should be

considered:

ü Technical availability of wind turbines

ü Technical availability of substation and grid system

ü Wind farm internal grid losses

ü Blade degradation and icing

ü Power management

ü Power curve performance

ü Noise and/or shadow induced operation restrictions

Turbine layout

For this area, the client, proposes the locations of the turbines. No micro siting was done by

Ridgeline Industrial team. Ridgeline Industrial considered a number of 6 existing wtg’s in the

neighboring area, the locations and type of the existing wtg’s were obtained from Ridgeline

Industrial data base. The detailed list of existing wtg’s can be found in the park calculation in

Annex 5 and in the next table.

Existing wtg’s and Gori II Wind Farm

Fig. 14: Gori II layout and existing turbine layout

Compared to single turbines, installing several wind turbines creates mutual interference of the

turbines. This results in a lower energy production of the farm compared to the sum of the single

productions of the turbines. The ratio between the energy production of the wind farm and the

sum of the single productions of the turbines is resulting into the so called “wind farm efficiency”.

This value is used as indicator for the quality of the wind farm design.

The mutual interference of the turbines, also called “wake effect”, is increasing with decreasing

distances between the turbines, as the wind flow is disturbed on the leeward side. The wind flow

remains disturbed until reaching a certain distance to the last turbine (generally greater than ten

times rotor diameter). This distance is required to regain the original energy level. Thus, it is

important that the turbines are positioned at a sufficient distance between the turbines, especially

in main wind direction.

The evaluation of the wind farm efficiency is accomplished by applying the respective module of

the software WindPRO 3.2. This software applies a relative simple mathematical model for the

description of the wake effect of a turbine. The calculation of the flow field and the wind speed’s

reduction in the wake serves as input for the respectively following turbine(s).

Fig. 15: Gori II wind map@ 90m

Concluding remarks

From a wind-climatologic point of view, the site GORI is suited for the technical use of wind

energy considering the average wind speed at P90 between 7.0 m/s – 7.4 m/s at 90 m a.g.l with

an equivalent roughness of 1.3-2.0 in the site location. Please notice that we see this appraisal as

an orientation for a comparison with similar developments. The main influence at the investigated

site results from the roughness in the further surroundings and also the planned wind parks under

development. The scope of the report was to establish the production values for the 6 turbine

models.

The energy yield forecast considers the wind turbines at the provided location must be

appreciated as a reference value due to uncertainties in relation to the effective technical

availability and the provided power curves. Therefore the energy yield forecast is not part of the

corroborated scope of this report. Any kind of liability in case that the economical-technical

target values are not achieved for damages / losses that might be caused by the direct or indirect

use of the results of this report is explicitly excluded.

The Ridgeline Industrial team accomplished this report according to the state of the art and to

the best of our knowledge. Based on the provided and considered measurement data, the report

has sufficient accuracy regarding the calculation and estimation of the park layout.

Description:The park power curve is similar to a WTG power curve, meaning that when a given wind speed appears in front of the park with same speed in the entire wind farm area(before influence from the park), the output from the park can be found in the park power curve. Another way to say this: The park power curve includes wake losses, butdo NOT include terrain given variations in the wind speed over the park area.Measuring a park power curve is not as simple as measuring a WTG power curve due to the fact that the park power curve depends on the wind direction and that the samewind speed normally will not appear for the entire park area at the same time (only in very flat non-complex terrain). The idea with this version of the park power curve isnot to use it for validation based on measurements. This would require at least 2 measurement masts at two sides of the park, unless only a few direction sectors should betested, AND non complex terrain (normally only useable off shore). Another park power curve version for complex terrain is available in windPRO.

The park power curve can be used for:1. Forecast systems, based on more rough (approximated) wind data, the park power curve would be an efficient way to make the connection from wind speed (and

direction) to power.2. Construction of duration curves, telling how often a given power output will appear, the park power curve can be used together with the average wind distribution

for the Wind farm area in hub height. The average wind distribution can eventually be obtained based on the Weibull parameters for each WTG position. These arefound at print menu: >Result to file< in the >Park result< which can be saved to file or copied to clipboard and pasted in Excel.

3. Calculation of wind energy index based on the PARK production (see below).4. Estimation of the expected PARK production for an existing wind farm based on wind measurements at minimum 2 measurement masts at two sides of wind farm.

The masts must be used for obtaining the free wind speed. The free wind speed is used in the simulation of expected energy production with the PARK powercurve. This procedure will only work suitable in non complex terrains. For complex terrain another park power curve calculation is available in windPRO(PPV-model).

Note:From the >Result to file< the >Wind Speeds Inside Wind farm< is also available. These can (e.g. via Excel) be used for extracting the wake induced reductions in measuredwind speed.

NoteTo get the most correct calculation results, wind statistics shall be calculated with the SAME model and model parameters, as currently chosen incalculation. For WAsP versions before 10.0, the model is unchanged, but thereafter more model changes affecting the wind statistic is seen. LikewiseWAsP CFD should always use WAsP CFD calculated wind statistics.

Latest research /Risø/ show that the threshold in RIX calculation typically work best with 40% (new default), and that delta Rix within+/- 5% should not give corrections. Cross predictions based on more mast can fine tune the threshold, see Cross predictor tool inwindPRO Meteo Analyzer. In windPRO LOSS&&UNCERTAINTY module, RIX correction can be calculated automatically as a bias basedon most recent recommended correction formulas, which can be found in EWEC2006 && 08 papers on Rix from Risø, see extractbelow:

The main conclusion based on use of the RIX method is that if both reference site (measurement mast) and predicted site (WTG) areequally rugged (Delta RIX < 5%), very small calculation errors are expected.If reference site (measurement mast) is very rugged, e.g. RIX = 0.2 and predicted site (WTG) are less rugged (e.g. RIX = 0), Delta RIXwill be -0.2 and according to the graph, 30% too low wind speed prediction at WTG site could be expected. This could lead to around60%*) too low calculated energy production.If the reference site is less rugged, e.g. RIX = 0, and the predicted site (WTG) are very rugged (e.g. RIX = 0.2), Delta RIX will be +0.2,and according to the graph, 30% too high wind speed prediction at WTG site could be expected. This could lead to around 60%*) toohigh calculated energy production.*) Doubling of energy prediction error based on mean wind speed error is a rough conversion, which holds for wind speeds around 8m/s. At 6-7 m/s tripling is more right, while only 1.5 factors should be used for 9 m/s, see graph below based on a typical WTG.

Productions are without wake losses.For further details, ask at the Danish Energy Agency for project report J.nr. 51171/00-0016 or see windPRO manual chapter 3.5.2.The method is refined in EMD report "20 Detailed Case Studies comparing Project Design Calculations and actual Energy Productions for Wind Energy Projects worldwide", jan 2003.Use the table to evaluate if the given power curve is reasonable - if the check value are lower than -5%, the power curve probably is too optimistic due to uncertainty in power curve measurement.

Productions are without wake losses.For further details, ask at the Danish Energy Agency for project report J.nr. 51171/00-0016 or see windPRO manual chapter 3.5.2.The method is refined in EMD report "20 Detailed Case Studies comparing Project Design Calculations and actual Energy Productions for Wind Energy Projects worldwide", jan 2003.Use the table to evaluate if the given power curve is reasonable - if the check value are lower than -5%, the power curve probably is too optimistic due to uncertainty in power curve measurement.

Productions are without wake losses.For further details, ask at the Danish Energy Agency for project report J.nr. 51171/00-0016 or see windPRO manual chapter 3.5.2.The method is refined in EMD report "20 Detailed Case Studies comparing Project Design Calculations and actual Energy Productions for Wind Energy Projects worldwide", jan 2003.Use the table to evaluate if the given power curve is reasonable - if the check value are lower than -5%, the power curve probably is too optimistic due to uncertainty in power curve measurement.

Productions are without wake losses.For further details, ask at the Danish Energy Agency for project report J.nr. 51171/00-0016 or see windPRO manual chapter 3.5.2.The method is refined in EMD report "20 Detailed Case Studies comparing Project Design Calculations and actual Energy Productions for Wind Energy Projects worldwide", jan 2003.Use the table to evaluate if the given power curve is reasonable - if the check value are lower than -5%, the power curve probably is too optimistic due to uncertainty in power curve measurement.

Productions are without wake losses.For further details, ask at the Danish Energy Agency for project report J.nr. 51171/00-0016 or see windPRO manual chapter 3.5.2.The method is refined in EMD report "20 Detailed Case Studies comparing Project Design Calculations and actual Energy Productions for Wind Energy Projects worldwide", jan 2003.Use the table to evaluate if the given power curve is reasonable - if the check value are lower than -5%, the power curve probably is too optimistic due to uncertainty in power curve measurement.

Productions are without wake losses.For further details, ask at the Danish Energy Agency for project report J.nr. 51171/00-0016 or see windPRO manual chapter 3.5.2.The method is refined in EMD report "20 Detailed Case Studies comparing Project Design Calculations and actual Energy Productions for Wind Energy Projects worldwide", jan 2003.Use the table to evaluate if the given power curve is reasonable - if the check value are lower than -5%, the power curve probably is too optimistic due to uncertainty in power curvemeasurement.

Description:The park power curve is similar to a WTG power curve, meaning that when a given wind speed appears in front of the park with same speed in the entire wind farm area(before influence from the park), the output from the park can be found in the park power curve. Another way to say this: The park power curve includes wake losses,but do NOT include terrain given variations in the wind speed over the park area.Measuring a park power curve is not as simple as measuring a WTG power curve due to the fact that the park power curve depends on the wind direction and that thesame wind speed normally will not appear for the entire park area at the same time (only in very flat non-complex terrain). The idea with this version of the park powercurve is not to use it for validation based on measurements. This would require at least 2 measurement masts at two sides of the park, unless only a few directionsectors should be tested, AND non complex terrain (normally only useable off shore). Another park power curve version for complex terrain is available in windPRO.

The park power curve can be used for:1. Forecast systems, based on more rough (approximated) wind data, the park power curve would be an efficient way to make the connection from wind speed

(and direction) to power.2. Construction of duration curves, telling how often a given power output will appear, the park power curve can be used together with the average wind

distribution for the Wind farm area in hub height. The average wind distribution can eventually be obtained based on the Weibull parameters for each WTGposition. These are found at print menu: >Result to file< in the >Park result< which can be saved to file or copied to clipboard and pasted in Excel.

3. Calculation of wind energy index based on the PARK production (see below).4. Estimation of the expected PARK production for an existing wind farm based on wind measurements at minimum 2 measurement masts at two sides of wind

farm. The masts must be used for obtaining the free wind speed. The free wind speed is used in the simulation of expected energy production with the PARKpower curve. This procedure will only work suitable in non complex terrains. For complex terrain another park power curve calculation is available in windPRO(PPV-model).

Note:From the >Result to file< the >Wind Speeds Inside Wind farm< is also available. These can (e.g. via Excel) be used for extracting the wake induced reductions inmeasured wind speed.

NoteTo get the most correct calculation results, wind statistics shall be calculated with the SAME model and model parameters, as currently chosen incalculation. For WAsP versions before 10.0, the model is unchanged, but thereafter more model changes affecting the wind statistic is seen.Likewise WAsP CFD should always use WAsP CFD calculated wind statistics.

PARK - RIX calculationCalculation: Park Gori II 4wtg's GE158-5.3 700 Hub=120.9m 17.07.2019

Latest research /Risø/ show that the threshold in RIX calculation typically work best with 40% (new default), and that delta Rixwithin +/- 5% should not give corrections. Cross predictions based on more mast can fine tune the threshold, see Cross predictortool in windPRO Meteo Analyzer. In windPRO LOSS&&UNCERTAINTY module, RIX correction can be calculated automatically as abias based on most recent recommended correction formulas, which can be found in EWEC2006 && 08 papers on Rix from Risø,see extract below:

The main conclusion based on use of the RIX method is that if both reference site (measurement mast) and predicted site (WTG)are equally rugged (Delta RIX < 5%), very small calculation errors are expected.If reference site (measurement mast) is very rugged, e.g. RIX = 0.2 and predicted site (WTG) are less rugged (e.g. RIX = 0),Delta RIX will be -0.2 and according to the graph, 30% too low wind speed prediction at WTG site could be expected. This couldlead to around 60%*) too low calculated energy production.If the reference site is less rugged, e.g. RIX = 0, and the predicted site (WTG) are very rugged (e.g. RIX = 0.2), Delta RIX will be+0.2, and according to the graph, 30% too high wind speed prediction at WTG site could be expected. This could lead to around60%*) too high calculated energy production.*) Doubling of energy prediction error based on mean wind speed error is a rough conversion, which holds for wind speedsaround 8 m/s. At 6-7 m/s tripling is more right, while only 1.5 factors should be used for 9 m/s, see graph below based on atypical WTG.

Productions are without wake losses.For further details, ask at the Danish Energy Agency for project report J.nr. 51171/00-0016 or see windPRO manual chapter 3.5.2.The method is refined in EMD report "20 Detailed Case Studies comparing Project Design Calculations and actual Energy Productions for Wind Energy Projects worldwide", jan 2003.Use the table to evaluate if the given power curve is reasonable - if the check value are lower than -5%, the power curve probably is too optimistic due to uncertainty in power curvemeasurement.

Productions are without wake losses.For further details, ask at the Danish Energy Agency for project report J.nr. 51171/00-0016 or see windPRO manual chapter 3.5.2.The method is refined in EMD report "20 Detailed Case Studies comparing Project Design Calculations and actual Energy Productions for Wind Energy Projects worldwide", jan 2003.Use the table to evaluate if the given power curve is reasonable - if the check value are lower than -5%, the power curve probably is too optimistic due to uncertainty in power curvemeasurement.

Productions are without wake losses.For further details, ask at the Danish Energy Agency for project report J.nr. 51171/00-0016 or see windPRO manual chapter 3.5.2.The method is refined in EMD report "20 Detailed Case Studies comparing Project Design Calculations and actual Energy Productions for Wind Energy Projects worldwide", jan 2003.Use the table to evaluate if the given power curve is reasonable - if the check value are lower than -5%, the power curve probably is too optimistic due to uncertainty in power curvemeasurement.

Productions are without wake losses.For further details, ask at the Danish Energy Agency for project report J.nr. 51171/00-0016 or see windPRO manual chapter 3.5.2.The method is refined in EMD report "20 Detailed Case Studies comparing Project Design Calculations and actual Energy Productions for Wind Energy Projects worldwide", jan 2003.Use the table to evaluate if the given power curve is reasonable - if the check value are lower than -5%, the power curve probably is too optimistic due to uncertainty in power curvemeasurement.

Productions are without wake losses.For further details, ask at the Danish Energy Agency for project report J.nr. 51171/00-0016 or see windPRO manual chapter 3.5.2.The method is refined in EMD report "20 Detailed Case Studies comparing Project Design Calculations and actual Energy Productions for Wind Energy Projects worldwide", jan 2003.Use the table to evaluate if the given power curve is reasonable - if the check value are lower than -5%, the power curve probably is too optimistic due to uncertainty in power curvemeasurement.

Productions are without wake losses.For further details, ask at the Danish Energy Agency for project report J.nr. 51171/00-0016 or see windPRO manual chapter 3.5.2.The method is refined in EMD report "20 Detailed Case Studies comparing Project Design Calculations and actual Energy Productions for Wind Energy Projects worldwide", jan 2003.Use the table to evaluate if the given power curve is reasonable - if the check value are lower than -5%, the power curve probably is too optimistic due to uncertainty in power curvemeasurement.
