• EDL - Australia’s largest independent remote energy producer
(>350MW)
• Owns and operates 29 projects in remote Australia - 27 years’
experience
• Fuel and technology agnostic with demonstrated record of
adapting technology to meet customers’ requirements
• CPRH is expected to reduce Coober Pedy diesel consumption by ~ 70%
• CPRH will demonstrate the application of renewables and EDL capability to meet our remote customers’ requirements:
‒ SAFE; RELIABLE; COST COMPETITIVE POWER
• ARENA grant will make it competitive
• EDL expects the combination of:
‒ Reductions in technology unit cost, including storage
‒ More efficient use of enabling units
‒ Higher fossil fuel costs
‒ Increased incentives to RE; imposts on fossil fuel
‒ Will result in COMPETITIVE renewable hybrids

• EDL has owned and operated the existing diesel power station at Coober Pedy since 2004
• CPRH is a MW scale; High penetration renewable generation fully integrated with existing diesel fuelled thermal
generation
• Part funded under the ARENA IRAR programme
• 5MW solar / wind plus enabling technologies to achieve ~ 70% diesel displacement over the year

CPRH – Power Generation Key Performance Factors
Component
Load & renewable
contribution
Annual Load: 11,800 MWh
Total renewable generation: 16,500 MWh
Renewable “spilled”: 6,500 MWh – 42% of RE generation - opportunity for storage
System losses: 1,400 MWh – 11 % of total generation
Net renewable contribution: 70%
Wind Average wind speed : 7.3 m/s
Capacity Factor: ~ 41%
Gross Annual Generation: 14,400 MWh
Solar PV Capacity Factor AC: 24.5%
Gross Annual Generation: 2,150 MWh
BESS Annual Discharge: 142 MWh Note: Battery used for intermittency control not storage
Changes From
Original Scope
At Feasibility: At FID:
Diesel penetration very similar whether 4/1 or 3 /2 combination
Following tender relative cost of wind and solar favoured
additional wind (limited wind turbine sizes)
Wind 3 MW 4 MW
Solar 2 MW 1 MW
Battery1MW / 250kWh
1.5 MW peak
1MW / 500kWh
1.5 MW peak
Specification modified to ensure required performance will be
achieved at end of life (extended long warranty)

• EDL intends to demonstrate what is technically feasible through operating of CPRH.
• Potential to increase penetration further through installation of storage – capturing spill for later use. Stage 2
• Until demonstration projects like CPRH and designers; operators and suppliers have reduced cost / increased
performance, high penetration hybrids are not competitive.
• EDL will look to introduce low penetration renewables across its portfolio and take the learnings from CPRH to
introduce additional generation and required enablers as and when they are competitive
• Ultimately renewables will become just another fuel choice to add to the current options. EDL is fuel and technology
agnostic – looking to provide bespoke solutions to suit the task.
Contractual Complexity
• At time of project conception an EPC wrap with integration guarantee was not available. EDL provides the wrap.
– 5 EPC contracts with 4 suppliers each with specific performance guarantees contributing to wrap guarantee.
– 4 stakeholders in PPA related matters – direct DCCP+EDL; Indirect SA Govt. -town subsidy + ARENA – Grant
Funds
• Substituting long term capital for long term operating costs (fuel) changes PPA risk profile cf thermal PPA
– Risks: Renewable resource (fuel); conversion; integration; load; LT competitive position.
EDL model
• EDL as a supplier of safe and reliable power through BOO structure
• Will add hybrids to its range of fuel and technology offerings
CPRH – Demonstration Value
Demonstration Value – 70% reduction in diesel consumption
EDL Intends to Build on CPRH – This is not a Once off
Intended Learnings
• Coober Pedy is remote from the grid, EDL supply is the sole source of power to DCCP distribution network
• EDL aiming to achieve at least 70% penetration and operate on 100% renewables for 50% of the time
• Requires substantial investment in enabling technology -
‒ Resistors; DUPS; BESS; Control system they contribute negative generation – parasitic load
‒ Represent at least 40% of the project cost
Coober Pedy - A microcosm of the NEM ?
• Small geographic spread exaggerates intermittency of renewables
• Single thermal plant versus NEM connection
Lower CostsHybrids cannot just rely on lower unit technology cost. Proponents need to push the envelope on mix and number of enablers
• Does system need inertia? Can battery / inverter systems substitute?
• How far can penetration be pushed before enablers; control and curtailment are required?
Energy Policy Objectives CPRH
Reliable System designed to be at least as reliable as thermal - to be demonstrated
Affordable Requires 40-50% grant plus a green credits to be competitive
Reduced Emissions Yes 70%
