Lord Howe Island Overview
• 700 kilometres north-east of
Sydney
• Settled in 1834
• No indigenous population
• World Heritage listed in 1982
Lord Howe Island

Lord Howe Island Overview
• 11 km long
• 300m to 2 km wide
• 2/3 of the Island is Permanent Park Preserve
• 360 residents
• Tourism is main industry
• Maximum 400 tourists
• Administered by the Lord Howe Island Board
Why the Project is Needed?
• Currently consume ~ 540,000L of diesel for power generation p.a.
• Power Saving Measures have largely been exhausted
– Diesel engines upgraded units in 2008
– 120kW of private solar panels installed since 2011
– Energy efficiency programs
– Fridge replacement programs
– Electricity use is controlled
• Potential winding back of NSW Government funding

Project Objectives
• Sustainable electricity generation for the Island at current high level quality of supply
• Improve community’s self-sufficiency
• Protecting the Island’s World Heritage and tourism values
• Lowest long term cost of energy production and reduce the impact of diesel price escalation
• Provide a pathway for other technologies such as electrical vehicles to be introduced
• A system that can be maintained and operated by the LHIB electricity generation team
• Provide a show case of what is possible in a remote community

Existing Electricity System
• Existing Generation– Main Powerhouse 3 x 300kW
– Manual Back Up Generator 1 x 424kW
– 120kW of Private Roof Top Solar approved – most connected
• All underground reticulation 6.6kV and 415V
22
Existing Electricity System
• System Load
– Average 260kW
– Min 160kW
– Max 460kW
– No significant motor loads
– Minimal seasonal variation
– Typical Diurnal pattern
– Load profile consistent across the week
23
Proposed Solution
• Option 1, consisting of:
– 2 x 200kW of Wind Generation
– 450kWac of Solar PV
– 400kW/400kWh of battery storage
• Option 2 consisting of:
– 550kWac of Solar PV
– 400kW/400kWh of battery storage
• In both cases– Sizing to be further optimised during detail design
– Overall Control System including existing diesel gensets

Projected Fuel Savings
Option 1Diesel Fuel Consumption (litres) 180,000
Reduction in Fuel Consumption (%) 67
Option 2Diesel Fuel Consumption (litres) 350,000
Reduction in Fuel Consumption (%) 35

Modelling
• Calculations performed using Homer
• Solar and wind potential outputs calculated by Homer checked with PVSyst and WAsP
• More than 15 months of onsite wind and solar data recorded at a minimum of 10min average with many months of 1min average data
• Actual Load data recorded for a number of years on 1 minute average basis
• Private solar actual performance over 12 months monitored and compared with solar record.
26
Current Project Status
• Solar PV and Battery Installation DA approved
• WTG approval not yet obtained
– LHIB as the consent authority has approved the project subject to undertaking some additional work to be done to support the DA application
– ASA has requested some additional modelling
– Commonwealth Government is currently assessing the EPBC referral
• Solar PV, Battery and Control System has been tendered
29
Timing
• Project is currently targeting completion in late 2018
• Commence construction of the Solar PV and Battery – August 2017
• Installation of over all control system late 2017
• Commence construction of the wind turbines mid 2018
• Staged commissioning commencing late 2017
30
Further Enhancement
• Predictive Technologies for Wind and Solar
• Smart Meter Installation on the Island
• Electric Cars and Charging Stations
• Increased renewables penetration
• Distributed storage options
