EDL and Renewable Generation

Remote Hybrids

• 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 will demonstrate the application of renewables and EDL capability to our remote customers’ requirements:

‒ SAFE; RELIABLE; COST COMPETITIVE POWER

• The combination of:

‒ Reductions in technology unit cost, including storage ‒ Increase in utilisation of technology units ‒ Higher fossil fuel costs ‒ Increased incentives to RE; imposts on fossil fuel will result in COMPETITIVE renewable hybrids Broader Interest

• In parallel EDL recently purchased the 30MW Cullerin Range wind farm
• Significant strategic initiative, extending our distributed generation portfolio and leveraging EDL capability
• We have complementary pipeline and network capability through our DUET sister companies
• We have strong appetite for further growth in mid scale grid connected solar and wind
• We can manage offtake as part of our wider generation portfolio
• No third party PPA required
• EDL can finance, using existing corporate debt facilities (investment grade) and our balance sheet
• Existing operating assets and shovel ready development projects
• Majority equity ownership (up to 100%)
• EDL involvement positive for ARENA/ CEFC/ concessional finance

DUET Group of Companies

• DUET Group (ASX:DUE), owner of energy

utilities in Australia with market capitalisation

• f ~$6.5b (Aug-16)
• DUET owns DBP, owner and operator of the

Dampier to Bunbury Natural Gas Pipeline (DBNGP)

• DBP Development Group (DDG) is

established as a vehicle for development of unregulated gas pipelines and associated infrastructure

• DDG and DBP share common resources,

policies and procedures under Support Service Agreements (SSAs)

• DUET acquired EDL in October 2015 and

further acquired Cullerin Range Wind Farm in July 2016

• Raised $1.92b in equity and over $2.4b of

debt for asset acquisition and operation in the FY15/16

Coober Pedy Renewable Hybrid – CPRH

Overview & Project History

• EDL has owned and operated the existing diesel power station at Coober Pedy

since 2004

• CPRH is a MW scale; High penetration renewable fully integrated with existing

diesel fuelled thermal generation.

• Part funded under ARENA IRAR programme
• 5MW solar/wind plus enabling technologies to achieve ~ 70% diesel displacement
• ver the year

Planning and Approval June 13 to March 16

• Concept to customer June 13 ARENA EOI Feasibility ARENA Application

May 2014

• EDL- ARENA Funding Agreement executed– July 14
• Development Consent; ILUA; Key Supply contracts tendered; Land Tenure

secured

• New PPA EDL – DCCP; FID April 16

Construction Phase – UNDERWAY

• Detailed designs being finalised
• Site Works commence Aug/Sept 2016
• Construction complete April 2017
• Commissioning complete July 2017
• Ongoing performance testing and refinement July 2017+

Operations Phase - 2017-2037 5

CPRH – Benefits and Demonstration Value

EDL believes CPRH will establish world benchmarks in large scale, remote, renewable penetration It will expand the boundaries established by King Island (KIREIP)

• Larger Scale - twice the renewable generation capacity and larger load demonstrating scalability
• Diversity of renewables - quality of solar resource and diurnal diversity sees larger % of solar
• Diesel Off - Diversity enables > time diesel off (estimated to be 50% of year) with smaller battery
• Scalable modular enablers - more rapid deployment, less call on remote resources reducing the remote cost premium.
• Complex commercial structure - IPP; Local & State Govt; ARENA; 5 key supply contracts

Benefits to the Coober Pedy community

• Lower cost of power to the expected diesel only case, over the long term
• Substantial stability in future power cost – approx. 70% fixed cost enables long term planning
• Reduction in greenhouse emissions – 130000t over project life
• Community contributions to opal community and Traditional Owners
• Local jobs and services during construction

Renewables are land hungry cf thermal generation

• Even in remote areas land tenure is multi layered
• At very least this involves process - TIME

Hybrids involve substituting capital for operating cost

• Requires common view on future costs of fuel including green

incentives and penalties.

• Capital investment very significant in context of local budget
• f remote communities and most mines

Why now?

• RE cost expectations encourage deferral of investment
• ARENA IRAR addresses this today but in the future?

Local politics are more volatile than Federal

Coober Pedy Resource and load characteristics

• 20 years of resource data - wind direction is very

consistent

• The wind in Coober Pedy is stronger at night,

complementing the solar resource

• Data from the wind mast installed in May 2014 has

confirmed the modelled wind speeds
