Summerhill solar farm to be built with CEFC finance

28 February

Newcastle City Council has secured a $6.5 million loan from Australia's Clean Energy Finance Corporation (CEFC) to help build the region's biggest solar farm.

The five-megawatt installation west of the city at the Summerhill Waste Management Centre will significantly reduce Council's annual $4 million electricity bill, after it doubled in the past two years.

The solar facility -- construction on which is expected to begin in June -- will save the city around $9 million over its 30-year life after construction and operational costs are factored in.

The installation's 14,500 panels will be built by international property and infrastructure group Lendlease, with most of the finance lent through the CEFC’s Local Government Finance Program, which offers councils flexible and competitive fixed rate, long-term finance.

"I'd like to thank the Clean Energy Finance Corporation for its incredible support of the City of Newcastle's sustainability charter," Newcastle Lord Mayor Nuatali Nelmes said.

"The solar farm will produce enough energy to run the equivalent of 1,300 households, which promises significant environmental returns for ratepayers and millions of dollars in savings on electricity costs.

"We are building sustainability into everything we do after reiterating our commitment last year to generate 30 per cent of our electricity needs from low-carbon sources and cut overall electricity usage by 30 per cent by 2020.

"Increasing our renewable energy capability and finding more energy-efficient solutions is an integral part of our long-term vision to become a smart, liveable and sustainable city."

CEFC CEO Ian Learmonth said: “We are delighted to work with Newcastle City Council on this landmark project, and to see its exciting transition to a sustainable city of the future.

“Councils across Australia administer a vast network of streetlights, community centres, libraries, sport and recreation facilities and other public access buildings. Newcastle is leading the way in financing a solar farm through the CEFC to help it manage the energy costs of these facilities.

“We encourage other councils to also invest in clean energy, which can free up council finance for other community-enhancing projects while locking in longstanding environmental and economic benefits for their communities.”

Council received development approval for the $8 million project from the Joint Regional Planning Panel (JRPP) last month, and preliminary works are now underway at Summerhill.

Lendlease is teaming up with renewable energy specialists Energy Made Clean (EMC) to design and build the facility.

It will cover an area of around five football fields between Summerhill's entry road and construction-waste area, on a capped landfill site that was once part of the Wallsend Borehole Colliery.

The winning tender to build the farm was selected following an expression of interest process that attracted 18 submissions from around the world.

Electricity generated will flow into the nearby Ausgrid substation to offset electricity used at Council facilities across the local government area.

The solar farm builds on one of Australia's most advanced renewable energy setups at a waste facility -- with a 2.2megawatt landfill gas generator and a small wind turbine already located at Summerhill -- and paves the way for future battery storage and electric garbage trucks.

Newcastle City Council recently joined the Cities Power Partnership, a Climate Council program in which cities and towns pledge key actions to reduce their climate impact.

Summerhill's solar farm and eight other solar installations - on the rooftops of Newcastle City Council buildings including an art gallery, museum, works depot and libraries - are part of actions endorsed.

Others actions include promoting more sustainable ways to travel, by providing cycling infrastructure and electric-vehicle chargers, and installing energy-efficient LED lighting.

The Newcastle project reflects the CEFC’s goal to invest $1 billion over 10 years to accelerate clean energy and energy efficient technology solutions in cities and the built environment, through its Sustainable Cities Investment Program.

Stockland powers up in New South Wales with significant solar retail roll out

5 March

Stockland is continuing to roll out the country’s largest property solar project, with its investment set to total $10 million across its NSW shopping centres in Western Sydney, the Hunter and the Illawarra.

Once complete, more than 17,000 solar panels will be installed on the rooftops of five Stockland shopping centres statewide, spanning Merrylands and Wetherill Park in Western Sydney to Maitland, Shellharbour and Nowra in the regions.

Combined, these installations will generate enough energy to power more than 1,305 homes each day for a year.1

NSW Minister for Resources & Energy, The Hon. Don Harwin MLC, joined Stockland Group Executive & CEO Commercial Property, John Schroder, at Stockland Wetherill Park today to inspect the largest rooftop solar project in Western Sydney.

John Schroder, Stockland Group Executive and CEO of Commercial Property, said: “Our Wetherill Park solar system has already generated 1.379 million kilowatt hours of energy since it was installed last summer.

“That’s around a quarter of the centre’s annual base building power and enough to power 223 homes every day.”

“Investing in technology like solar is not just good for the environment, it also makes good business sense. Several studies across the globe have demonstrated that green retail town centres are cheaper to operate and can result in increased customer spending.”2

Stockland is the most significant investor in rooftop solar in the country, with a $23.5 million national investment – Australia’s largest ever property solar project, announced last year.3

Once complete, the project is expected to produce 17.2 GWh of energy every year, the equivalent to driving an electric car around the world 2,381 times.

Paul Peters, Verdia CEO, said: “As Stockland’s delivery partner, our value is in accelerating and de-risking the program to generate savings as soon as possible. In just 12 months, we will install more than 10MW of solar PV across Stockland centres in three states.”

John Schroder continues, “We’re extremely proud to be setting a new standard in solar for retail and for NSW, helping create sustainable energy for our retailers, our customers and the communities we operate in.

"We believe in solar as a major part of the mix for Australia’s future energy needs and that our investment is an important step within the large scale commercial property arena.”

Stockland owns and manages the most Green Star (Design & As Built) rated shopping centres in Australia, and already has more solar panels installed across its assets than any diversified property company listed in Australia.

A record year for small-scale solar

6 March

Australia has cemented itself as a world leader in the use of rooftop solar with yet another record for installed capacity.

Figures released today by the Clean Energy Regulator show that there was more than 1057 megawatts of capacity installed last year, beating the previous record of 1035 megawatts set in 2012.

This brings the total installed small-scale capacity in Australia to more than 6000 megawatts.

Australia has the highest penetration of rooftop solar in the world. One in five Australian homes has rooftop solar and an increasing number of small businesses are making the most of the financial and environmental benefits of solar.

The Clean Energy Regulator predicts 2018 will see at least another 1000 megawatts of capacity added to Australian rooftops.

The Small-scale Renewable Energy Scheme provides financial incentives for households and businesses to install renewable energy systems to reduce their reliance on the electricity grid and reduce their emissions.

Earlier this year, the Clean Energy Regulator announced the Renewable Energy Target will be met thanks to more than $12 billion of investment in large-scale projects.

Whether it be small or large-scale projects, there continues to be record breaking level of investment in renewable energy under the Turnbull Government.

Investment in renewables is part of the Turnbull Government’s technology neutral approach to delivering a more affordable and reliable energy system.

University of Adelaide lighting up Roseworthy campus with renewables

7 March

The University of Adelaide’s Roseworthy campus is closer to generating, supplying and storing nearly half its energy needs thanks to $780,000 from the State Government’s $150 million Renewable Technology Fund.

The funding will support the installation of a $1.56 million 0.5MW/2MWh battery storage system and increase the benefits of a $4.2 million 1.2MW solar project that will supply more than 40 per cent of Roseworthy’s annual energy needs.

The project is part of the University’s Campus Sustainability Plan, towards which it is investing $14.4 million over the next three years.

The University of Adelaide is ranked in the top 1 per cent of universities worldwide and a member of the Group of Eight, making it one of Australia’s leading research universities.

The project will create up to 23 jobs during construction of the solar and battery storage and one ongoing position, while the University will perform three research projects each year connected to the energy storage system for the next three years.

It will also assist the University to include topics such as remote-energy management, energy storage and load flex in various tertiary education courses.

The $150 million Renewable Technology Fund was established in March 2017 to support further integration of renewable technologies, fast-track South Australia’s energy transformation and improve electricity market competition.

“We’re excited about the opportunity to improve energy sustainability at our Roseworthy campus. This is part of a suite of emissions reduction projects under the University’s Campus Sustainability Plan,” says University of Adelaide Chief Operating Officer Bruce Lines.

“The installation of a state-of-the-art battery storage system in addition to our solar energy project at Roseworthy campus will greatly reduce our reliance on grid electricity, and builds on an existing commitment towards the Carbon Neutral Adelaide program.

“The saving on the grid will be like switching off the power at more than 370 Adelaide homes for an entire year – so it’s a major saving. It will also help us to test the performance and reliability of battery storage technology in hot, dry conditions, which will benefit industry and the community,” says Mr Lines.

“The University of Adelaide is one of the world’s leading research institutions, and the State Government is pleased to help it contribute to South Australia’s world-leading reputation in renewable energy and storage technology,” says Energy Minister Tom Koutsantonis.

“This is a great example of a project that will lower electricity costs by pairing solar panels with batteries on a large scale.

“Renewable energy projects like this one at the University of Adelaide also reduce demand on the grid during peak times, which puts downward pressure on power prices for all South Australians,” says Minister Koutsantonis.

World's largest solar and wind powered hydrogen plant to be developed in SA

7 March

Neoen has been awarded an initial $1 million grant from the State Government's Renewable Technology Fund to finalise its plans for a SOMW electrolyser facility at its proposed wind and solar farm at Crystal Brook.

A further $4 million grant and $20 million loan has been awarded to support construction of the project, which is subject to development approvals.

The Hydrogen Superhub, set to be the largest co-located wind, solar and hydrogen production facility in the world, represents an investment by Neoen of up to $600 million into South Australia and will create about 260 jobs during planning and construction and about 40 ongoing positions.

The facility is projected to produce up to 20,000kg of hydrogen per day with renewable hydrogen product offtake arrangements to be finalised during the planning phase. The scale of the proposed Hydrogen Superhub opens the opportunity for South Australia to export renewable energy in the form of hydrogen products to emerging markets in Asia.

This project follows the release of the Hydrogen Roadmap for South Australia in September last year, designed to accelerate investment in hydrogen infrastructure and technologies in South Australia.

Background

The Hydrogen Superhub will have the potential to combine up to 1S0MW Solar and up to 1S0MW of wind power generation with large scale SOMW electrolyser installation and up to 400MWh battery storage.

Neoen has financed over 400MW of solar, wind and battery storage projects in South Australia and has built a strong local presence and experience in the development, financing, construction and operation of renewable energy technology projects.

The $1S0 million Renewable Technology Fund was established in March 2017 to support further integration of renewable technologies, fast-track South Australia's energy transformation and improve electricity market competition.

Three other hydrogen projects are receiving funding from the Fund are: a hydrogen production, storage and fuel cell system at UniSA's Mawson Lakes campus, a 1.2SMW hydrogen production facility at the Tonsley Innovation Precinct and a 1SMW hydrogen and ammonia production facility to be constructed near Port Lincoln.

The Renewable Technology Fund also supported the construction of the Tesla big battery at Jamestown, a project delivered by Neoen.

The State Government's Hydrogen Roadmap outlines how the state's world-leading renewable wind and solar assets can attract international investment in hydrogen production and accelerate our transition to a zero carbon economy.

Quotes attributable to Energy Minister Tom Koutsantonis

Energy storage is the key to delivering very cheap renewable energy around the clock, which is why the State Government is supporting the development of a broad range of world-leading projects, including in hydrogen production and storage.

Our Hydrogen Roadmap has laid the groundwork for South Australia to become a world leader in the emerging hydrogen production industry, and to benefit from the economic opportunities likely to flow from it.

More renewable energy mean cheaper power and I'm pleased the State Government can partner with Neoen to once again develop a world-leading renewable energy and storage project following the construction of the Tesla battery at Jamestown.

This Superhub will enable NEOEN to produce renewable hydrogen for overseas export markets and create about 300 construction and ongoing jobs for South Australians.

Quotes attributable to Managing Director of Neoen Australia Franck Woitiez

The Hydrogen Superhub project aims to produce hydrogen at internationally cost competitive rates, allowing for international export of renewable hydrogen gas products.

This project aims to take South Australian made renewable electricity in the form of hydrogen based compounds to important national and international markets in Asia and beyond. It has the potential to reach beyond our electricity grids, and supply South Australia's locally produced clean energy to other states and to our nearby trading partners.

This exciting project would not have happened without the South Australian Governments Hydrogen Road Map. As a result, the state is attracting substantial investment around this cutting-edge technology.

Trialling grid stability services provided by wind farms

8 March

The Coalition Government, through the Australian Renewable Energy Agency (ARENA), is providing almost $500,000 to a north east Tasmanian wind farm to test the feasibility of wind farms providing services that help stabilise the electricity grid.

If successful, the $1 million trial could see more Australian wind farms providing the services which would not only further stabilise the grid, but also lower electricity prices through commercialisation.

The Australian Energy Market Operator (AEMO) continuously balances energy supply and demand by procuring ‘frequency control ancillary services’ (FCAS) from participating generators and demand response providers.

When frequency is too low, it is increased by FCAS to either increase generation or decrease demand. When frequency is too high, it is reduced by FCAS which lowers generation or increases demand.

In other words, the frequency (and stability) of the grid is maintained by providing a fast injection or reduction of energy.

“As Australia’s Chief Scientist Dr Alan Finkel in his review of the National Electricity Market highlighted, tighter frequency control is important for increased security,” Minister Frydenberg said.

Woolnorth Wind Farm Holdings own and operate the 168MW Musselroe wind farm which produces approximately five per cent of Tasmania’s electrical energy needs annually.

“Unlike coal and gas power stations, wind farms do not currently provide FCAS. This Tasmanian trial, however, could see that change,” Minister Frydenberg said.

“If both technically and commercially feasible, wind farms across Australia will have the opportunity to contribute to the stability of the grid and develop a new revenue stream that helps lower electricity prices.”

The Coalition Government's investment in this trial is part of our plan to deliver an affordable and reliable energy system as we transition to a lower emissions future.

Woolnorth will also examine the potential of adding storage for surplus energy to the wind farm.

Paving the way for concentrated solar thermal in Australia

8 March

The Australian Renewable Energy Agency (ARENA) today released a report outlining how concentrated solar thermal (CST) technology could be a commercially viable form of dispatchable renewable energy within a decade.

Last year, ARENA called for industry participants worldwide to respond to a Request for Information (RFI) exploring the potential for solar thermal to be rolled out in Australia. A total of 31 responses were received from both Australian and international companies.

These responses will now inform ARENA in preparing a strategy to support CST in Australia, including considering future funding opportunities for CST.

ARENA is also funding a roadmap for CST to examine requirements for accelerating commercial deployment in Australia. The roadmap is underway and will be completed in mid 2018, with the results also used to inform ARENA’s CST strategy.

CST systems use mirrors to concentrate and convert sunlight to heat at high temperatures. The heat is then stored and used to produce steam, which is then run through a turbine to generate electricity. Most CST plants are large scale and incorporate between 3-15 hours of thermal energy storage.

Large scale CST technology is yet to be introduced in Australia, but there are approximately 100 utility scale CST plants operating worldwide, mostly in the United States and Spain totalling around 5GW. The total CST capacity is expected to double to 10 GW over the next five years, driven by new plants in China, South America and Africa.

The report released today, which was prepared by ITP Thermal, found strong confidence in the future of CST, with a number of global industry leaders interested in being involved in the deployment of CST in Australia.

All responses highlighted that CST could help to address Australia’s energy storage and dispatchability needs by providing reliable, responsive and flexible electricity generation at any time of day or night. Respondents noted that CST plants operate in a way similar to that for existing thermal power stations, allowing them to be easily incorporated within the electricity network. Respondents also noted the cost of CST is expected to fall in the coming years.

ARENA CEO Ivor Frischknecht said the RFI was an important stepping stone towards bringing commercial scale CST to Australia.

“While still not cost-competitive with other forms of new-build power generation, the ability to store energy and be able to dispatch renewable energy at any time will be of increasing value, and this information shows there is strong support for CST,” he said.

“We are now considering funding opportunities to assist in creating a pathway for CST to become commercially viable in Australia in the coming years,” Mr Frischknecht said.

In the meantime, Mr Frischknecht said ARENA welcomes applications for a well developed CST project under ARENA’s Advancing Renewables Program which provides funding for renewable energy projects year-round.

“While we are busy working out our roadmap for the industry, our door is always open to high quality, innovative renewable energy demonstration projects that can help bridge the gap to commerciality for new technologies.

“If any company has a prospective project with well-developed financing, an offtake agreement and technical details mapped out, they don’t need to wait and we would encourage them to apply,” he said.

ARENA is also currently working with the Clean Energy Finance Corporation (CEFC), in consultation with the Infrastructure and Project Financing Agency (IPFA), to provide the Commonwealth Government with advice on Solar Reserve’s 150MW Aurora CST project proposed for Port Augusta, including its suitability for a federal loan of $110 million.

Infrastructure in the region does not support OZ Minerals’ current activities and future regional expansion plans. The new transmission line will meet the company’s operational requirements and enable its growth strategy for the region.

Agreements are being progressed with industry participants and the State Government to facilitate the development and operation of the line:

  • ElectraNet to build, own, operate and maintain the new transmission line
  • SolarReserve, a renewable energy developer, to cost share a section of the line’s construction and operation
  • BHP, Olympic Dam, for land access and support for a regional energy supply plan
  • The State Government for access and regulatory requirements
  • Communities and landowners along the route of the line

The second phase will be progressively developed and includes procurement, to take place in the latter half of the year, and generation which includes cost saving initiatives and consideration of renewable energy options.

OZ Minerals Chief Executive Officer, Andrew Cole said, “In developing the strategy, we have addressed reliability, security and affordability for our current mining assets and enabled our ambitious growth aspirations for the region and beyond.

“The new transmission line will enhance security of power supply, reduce line losses and enable the execution of the Prominent Hill mine plan, Carrapateena operations and the exploitation of future optionality for district expansion at Carrapateena.

“The cost impact of the new line will be a 3% to 4% increase in Prominent Hill’s Life of Mine All-In Sustaining Costs (AISC) from mid-2020 (previously guided at 2% to 5%), offset by a circa 1% cost benefit at Carrapateena. These cost estimates are based on SolarReserve’s development of its solar thermal generation and storage facility near Port Augusta.

“The line will have the capacity for other users to draw power or input generation, which will improve the economics for other developments in the region and, as more users connect, OZ Minerals’ operating costs will reduce proportionately.

“Our approach to Power Procurement has vindicated our decision to sign a short term, 18 month pricing agreement in 2017, as independent agencies are forecasting a downward trending power price market. As a result, we have flexibility to commit to short term or long term contract pricing, or a combination of both, and consider generation source options as they become more affordable,” Mr Cole said.

“The power strategy also includes a modest onsite solar generation plant at Prominent Hill.

“Elements of the second phase of our strategy, comprising power procurement, generation and site energy saving initiatives, will be progressively developed and actioned.”

Phase 2

Power Procurement and Generation

Electricity pricing remains fixed at Prominent Hill to the end of 2018. OZ Minerals’ future sourcing strategy will contemplate a traditional approach to supply as well as alternative generation sources.

Energy prices are currently trending downwards.

The past 12 months have seen a range of additional energy solutions come on line in South Australia including new diesel generation and battery storage under the State Government’s Energy Plan. Additional generation has been constructed with more generation planned including SolarReserve’s solar thermal generation and storage facility near Port Augusta and other renewable sources.

The Australian Energy Market Operator’s December 2017 regional generation outlook indicates that 38 new projects are planned to supplement existing generation in South Australia.

Site Energy Saving Initiatives

As part of the South Australian Energy Productivity Program, an energy audit was conducted at Prominent Hill to identify ways to lower energy consumption. A resulting initiative looks at linking ventilation fans to smart technology, enabling on-demand usage in the Prominent Hill underground and reducing secondary ventilation energy consumption by approximately 15%, saving up to 1.5% of total site power usage.

OZ Minerals has received conditional approval for a grant from the South Australian Government to install a solar plant and storage capabilities at Prominent Hill, which is anticipated to reduce grid energy requirements. The grant is valued at up to $2.5 million, and OZ Minerals is currently looking at optimising project plans.

The solar plant at Prominent Hill will increase OZ Minerals’ understanding and capability with respect to renewable energy and generation sources which may be required for operations in remote locations such as West Musgrave.

OZ Minerals is also working with a number of potential energy developers to explore and innovate new, additional renewable options across OZ Minerals’ assets.

At Carrapateena, solar panels provide a number of opportunities with the potential to reduce diesel consumption and lower costs during construction.

A wind mast will be installed at the West Musgrave project to assess the viability of wind generation. The further scoping study base case identified solar photovoltaic combined with diesel as a project energy generator. The site presents opportunities for alternative renewable generation as the price point continues to reduce.

Project Briefs

Palmer Wind Farm

The Environment, Resources and Development Court of South Australia has dismissed an appeal against the development of Tilt Renewables’ Palmer Wind Farm in the Mount Lofty Ranges in South Australia. In late 2015 the Mid Murray Council granted development plan consent to an amended proposal involving a reduced, 103 turbine wind farm.

 

Sandigo Solar Farm

ESCO Pacific’s Sandigo Solar Farm in NSW was placed on public exhibition until 8 April. The proposed Sandigo Solar Farms project is a utility-scale renewable energy project that would comprise up to two solar farms located at Sandigo in NSW, one each at Kywong and Glen Moira, generating up to a combined total of 300 MW (AC). It has an estimated capital investment value of $240mil, and will employ around 130 people in construction and 4 when operating.

 

Moama Solar Farm

A development application for Terrain Solar’s proposed 28 MW Moama Solar Farm in NSW was referred to Western Joint Regional Planning Panel by Murray River Council. The project has an estimated capital investment value of almost $30mil.

 

Coopers Gap Wind Farm

EPC contractor for PARF’s 123-turbine, up to 453 MW Coopers Gap Wind Farm near Cooranga North in Queensland, GE-CATCON, has engaged Walbridge Gilbert & Aztec and Consolidated Power Projects Australia Pty Ltd to carry out the civil and electrical balance of plant contract which includes design, supply and installation of access roads, turbine foundations, electrical reticulation and transmission lines, operation and maintenance facilities and upgrades of existing infrastructure. Works started in February 2018 with the first wind turbine components expected to be delivered to site in May 2018, the substation expected to be ready for service in Q4 2018, and practical completion of the project is expected in Q4 2019.
