THE FUTURE OF CLEAN ENERGY FOR SOUTH AUSTRALIA IS HERE

SOLAR POWER, DAY AND NIGHT SolarReserve: The leading worldwide developer of solar thermal solutions with energy storage – with differentiated proprietary technology and a proven track record of success. GLOBAL DEVELOPER OF LARGE-SCALE SOLAR THERMAL

WORLD’S LEADING ENERGY STORAGE TECHNOLOGY

PROJECTS IN OPERATION AROUND THE WORLD

• Development pipeline of over 13,000 megawatts (MW) across the world’s most attractive solar markets includes solar thermal (CSP), solar photovoltaic (PV) and solar hybrid plants (CSP and PV combined).

• Commercialised world’s most efficient and lowest cost CSP with integrated storage that solves the intermittency issues experienced with other renewable energy sources.

• More than $1.8 billion of projects in operation globally.

• Long-term power contracts for 456 MW representing $2.7 billion of project capital, with an additional 2,000 MW of projects under award.

• Unmatched proprietary CSP technology allows solar to operate like a conventional coal or gas power station and deliver power into peak demand periods, but without any fossil fuels and at a fraction of the cost of other storage technologies.

• Global presence with headquarters in California and seven international offices strategically located in Australia, Africa, the Americas, the Asia-Pacific region, the Middle East, and Europe. • Experienced management team with over 27,000 MW and $48 billion of combined transaction experience in 25 countries.

• The genesis of the technology is from Rocketdyne’s work on building rocket engines for the NASA space program. SolarReserve now owns the intellectual property, patents and has 10 rocket scientists on staff working on future generations of the technology.

• Flagship 110 MW Crescent Dunes CSP project in Tonopah, Nevada with 10 hours of storage – in 2015 achieved commercial operation under the Power Purchase Agreement, a 25-year full offtake contract with NV Energy. • SolarReserve has been awarded 346 MW of projects in South Africa, with 246 MW currently operating. • SolarReserve performs Construction Management, Project Management and Asset Management services to minimise project level risks and maximise performance and returns.

Benefits of SolarReserve’s technology for South Australia • The technology, which utilises molten salt to store energy, is able to provide fully dispatchable electricity to the network when electricity is needed most – day and night. • Together with SolarReserve’s technology design, the use of molten salt represents the most flexible, efficient and cost-effective form of large-scale energy storage available today. • The technology is proven at an operating commercial-scale facility, a 110 megawatt project called Crescent Dunes in Nevada USA, which came online in late 2015. The project’s 1,100 megawatt-hour storage capability alone is about the same size as all of the world’s utility-scale batteries in operation today, combined – and at a fraction of the cost. • Molten salt is non-toxic and inert, safe for workers and the environment.

• As renewable energy penetration grows in Australia, the need for utility-scale renewable generation with storage technology will become increasingly important to provide firm blocks of electricity which can’t be provided from wind and solar PV plants which have variable output. Because of its integrated storage, the technology can reliably deliver power into peak demand periods and support transmission system reliability. • The technology is future proof. With increased penetration, renewables such as wind and solar PV will contribute less and less to meeting peak demands, but solar thermal with storage will maintain its value over the long term, even as demand profiles change. The technology will help to suppress wholesale price volatility, benefiting electricity consumers in the state, and improving the operating conditions for businesses in the state. It will help avoid the price spikes that South Australia has seen in recent months.

• South Australia, the leading state for renewable energy in Australia, is positioned to become the leading state for dispatchable solar thermal energy in Australia – creating an entirely new industry for South Australia. The supply chain which will be developed in the state from this project will be leveraged for other solar thermal projects in South Australia and the broader region. • These projects will create much needed jobs for South Australia. Each project will create up to 4,000 direct, indirect and induced jobs during construction and around 50 jobs during the operations phase. • As SolarReserve’s technology is powered entirely by the sun, without the need for any backup fuel, it is able to provide electricity price certainty over its 30 year life, unaffected by the rising price of gas.


THE AURORA SOLAR THERMAL PROJECT

HOW IT WORKS

is concentrated and 1 Sunlight

directed from a large field of heliostats to a receiver on a tall concrete tower

AURORA WILL BE THE MOST ADVANCED SOLAR THERMAL PROJECT IN AUSTRALIA AND A LANDMARK FOR THE REGION

2 Liquid salt from the cold salt tank

is pumped through the receiver where it is heated to 566 °C

Location: Approximately 30 km North of Port Augusta, South Australia, adjacent to the Stuart Highway

6 Condensed steam from the

steam turbine is recirculated for reuse

3 The heated salt from the receiver

is stored in the hot salt tank

Point of interconnection: BHP’s 275 kV transmission line, approximately 6 km east of the site

4 Hot salt is pumped from the hot

Electricity production: Approximately 495,000 megawatt hours annually

Homes powered: Approximately 90,000 South Australian homes

In a solar thermal system with energy storage, the heat transfer medium - molten salt - retains heat so well that it enables the plant to generate electricity for hours when the sun is not shining.

CO2 displaced: Approximately 200,000 tonnes annually Job creation: Up to 4,000 direct, indirect and induced jobs during construction and 50 jobs during the operations phase

Investment: Approximately $650 M, of which up to 60% is expected to be expended in South Australia

Location Approximately 30 km North of Port Augusta, South Australia, adjacent to the Stuart Highway.
