SMALL HYDROPOWER PROJECTS
Black & Veatch has been providing services to the hydropower industry for almost 100 years. We have worked on major projects across the water and energy industries and are actively engaged in projects from early concept definition and research to turnkey project execution.
EXTENSIVE KNOWLEDGE OF RENEWABLE ENERGY
Black & Veatch has extensive knowledge
of all aspects of renewable energy.
Our experience ranges from small 10kW
systems for our water utility clients,
to run-of-river plants of less than 1MW
to large-scale utility generation greater
than 1000MW.
Whatever your requirements, we can
help you identify, evaluate, design and
implement the right solution to meet
your needs.
DESIGN, CONSTRUCTION & INSTALLATION SCOTTISH WATER HYDROPOWER SCHEMES | Scottish Water |
Scottish Water has an ambitious target to generate more power than it
consumes by 2018. Black & Veatch has helped to deliver a large component
of this target by completing six hydro turbine installations across five sites.
These consisted of both on and off site schemes; turbines being placed on
compensation flow lines to rivers and on raw water intakes to treatment works
for example.
Scottish Water initially undertook a feasibility study of 45 potentially suitable
sites, of these it was concluded 33 of the sites could be used to generate power
from hydro turbines. For 8 of these sites, Black & Veatch undertook an outline
design to devise a ranking of the sites based on their economic viability.
On the basis of their ranking, Black & Veatch was awarded design-and-build
contracts for delivery of 5 turbine installations across 5 sites, with a sixth
already having been completed at Glencourse in 2012.
For those sites chosen to be developed, power generation potential varied
between approximately 100 to 700kW. In all cases, the available head is
greater than 10 metres (m), with the highest being 83m. Flows range from 100
to 1,700 litres per second (l/s). Delivery was a multi-disciplined undertaking,
encompassing planning, modelling, design, specialist hydropower technical
expertise and construction management.
Each site had its own set of complexities, but all of the projects shared the
common aims of limiting the impact on existing operations whilst maximisating
of output and efficient performance. The integrated design and build team
addressed buildability issues at an early stage and ensuring efficiencies across
the programme. Importantly, the use of an integrated team has also helped
improve construction safety.

SELECTED PROJECT EXAMPLES
BL ACK & VEATCH
PENYCEFN WATER TREATMENT WORKS | Dwr Cymru Welsh Water |
Black & Veatch has completed the design, procurement,
installation and commissioning of a hydropower facility at
Penycefn Water Treatment Works. The scope was agreed
following a renewable technology cost/benefit study by
Black & Veatch and was part of the concurrent works upgrade.
The 16kW hydro device has a regulation function allowing flow
control as well as energy recovery for electricity generation.
PENYCEFN WATER TREATMENT WORKS | Dwr Cymru Welsh Water |
A similar, but larger installation is now operational for Crai Water
Treatment Works in South Wales. The installation at Crai,
however was particularly challenging due to its location in the
Brecon Beacons National Park.
Black & Veatch’s experience of obtaining planning permission
for such installations, ensured that Dwr Cymru secured planning
consent and the design of the scheme incorporated a number of
environmental and ecological elements to realise a ‘conservation
considerate’ scheme.
GLENCORSE WATER TREATMENT WORKS (WTW) | Scottish Water |
Black & Veatch completed the design and managed the
installation of a 230kW Turgo hydroturbine at Glencourse Water
Treatment Works. Glencorse provides a reliable and safe drinking
water supply for 450,000 people across Edinburgh and parts
of Midlothian. Not only does the scheme provide 20% of the
facility’s needs, it ensures sustainable economic growth for
the region by allowing the plant to be scaled up to meet
future demands.
Sustainability and community have been at the project’s heart
throughout planning, design and execution. The WTW’s size and
visual impact was reduced significantly through Black & Veatch’s
choice of treatment process. Using grass roofs for the largest
structures also helped blend the works into its surroundings.
Producing pipes adjacent to the site cut costs and carbon
emissions in addition to making construction safer and easier.
Glencorse has won an impressive ten awards, including;
�� CIWEM World of Difference - 2011
�� CCS Considerate Constructor Gold - 2012, 2011 & 2010
�� RoSPA Gold - 2011, 2010 & 2009
�� Scottish Water Excellence in S-afety - 2009
�� CeeQual Whole Project - Excellent (84%)
�� CeeQual Outstanding Achievement - Relations with the Local Community & other Stakeholders

CONCEPT DESIGNLOW-HEAD HYDROPOWER GENERATION IN AN EXISTING FACILITY | Thames Water |
Black & Veatch investigated renewable energy generation for an
existing water management structure. A run-of-river ‘mill’ which
used to power water distribution pumps was made redundant
in 1983. Black & Veatch completed a concept design study for
using the facility to generate electricity.
HYDROPOWER GENERATION AT HAMPTON WATER TREATMENT WORKS | Thames Water |
Black & Veatch reported on the viability and prepared a concept
design with indicative cost estimates for a hydropower scheme
located at the Hampton water treatment works.
Black & Veatch undertook a comprehensive review, offering
specific advice on: dynamic heads and flow rates, energy recovery
management and yield, turbine types and selection, failure
scenarios and pressure transients, spatial planning, operation
risks, integration with the existing site and maintenance issues
and costs.
FEASIBILITY STUDIESSCOPING ASSESSMENT OF HYDROPOWER FEASIBILITY AT FIREPOOL WEIR | Environment Agency |
As part of a larger weir development, Black & Veatch carried
out a high level review of a hydro scheme at Firepool Weir.
This review, which covered an investigation of the opportunity
for an Archimedes screw generator, included an analysis of the
flow duration curve, preliminary sizing of the plant, predicted
energy capture and the capital investment required.
The analysis also looked at the revenue that could be generated
from Feed-In Tariffs and gave an appraisal of both the investment
case at the site and the potential CO2 savings.
TWO HYDROPOWER SCHEMES | Confidential Client |
Black & Veatch provided the client with two feasibility reports for
two separate potential hydropower schemes (30-70kW) in Wales.
An estimation of the potential energy yield was made by
considering the gross head, flow duration curve, hydraulic
losses and mechanical and electrical efficiencies.
The work included carrying out pressure tests to obtain an
accurate hydraulic characteristic curve for each scheme.
Based on this information, turbines were selected and the
mechanical and electrical layouts presented. Feasibility was
then assessed taking into consideration the capital and operating
costs and all potential revenues.
SIX HYDROPOWER SCHEMES | Confidential Client |
Black & Veatch provided the client with a pre-feasibility report
for six potential mini hydropower installation sites (20-100kW)
in England. For each site a hydrological assessment and site
visit were carried out. An estimate of the potential energy yield
was made by considering the gross head, flow duration curve,
hydraulic losses, and mechanical and electrical efficiencies. An
overall project layout and preliminary estimation of the capital
costs of the project were determined.
HYDROPOWER SERVICES FRAMEWORKUNITED UTILITIES OPERATIONS SERVICES | UUOS |
Black & Veatch was a framework partner for the provision of
hydropower development services for United Utilities within the
Welsh Water region. Black & Veatch carried out three hydropower
appraisals (<50kW), two of which were progressed to installation
under the management of Black & Veatch.
DEVELOPMENT STUDY FOR WALES | Environment Agency |
As part of a UK wide Carbon Reduction Plan for the Environment
Agency, Black & Veatch reduced a list of over 60 potential
hydropower sites in Wales to a shortlist of five by means of
a desk study. Following site visits, Black & Veatch produced
environmental, economic and planning appraisals with outline
designs for the selected sites. Wind and solar photovoltaic
renewable energy applications were also included in the study.
RESOURCE STUDY FOR SCOTLAND | Scottish Government |
Black & Veatch provided technical and financial expertise on
small hydropower feasibility studies. The conclusions of our
appraisals fed into the survey of hydropower resource across
Scotland, with the final study being completed by Nick Forrest
Associates in collaboration with the Scottish Institute of
Sustainable Technology (SISTech).
