part of the solution

alcoa and greenearth energy sign memorandum of intent
Alcoa of Australia and Greenearth Energy this month signed a ground-breaking Memorandum of Intent (MOI) in a critical first step towards the establishment of base load renewable energy generation in Victoria.

Alcoa has operated a power station in Anglesea for over 40 years. Greenearth Energy’s proposed Geelong Geothermal Power Project (GGPP) resource area is approximately 9km northwest of the Alcoa operation.

Informal discussions have been held between Alcoa and Greenearth Energy for nearly two years, with the organisations recently agreeing to commence formal discussions under the framework of this MOI.

Subject to a range of technical, commercial and legal parameters and dependent on the continuing operation of Alcoa’s Anglesea facility, the areas of potential collaboration to be investigated via the MOI will include:
  • Identification of a site sufficient for the GGPP Stage 1 (Proof of Resource/Concept) and Stage 2 (Demonstration 12MWe) on land currently leased by Alcoa;
  • Grid connection of the GGPP via Alcoa infrastructure assets;
  • Base load renewable energy off-take as a result of a successful GGPP Stage 2 Demonstration, 12MWe geothermal energy plant (PPA)
  • Purchase of Renewable Energy Certificates (REC's) as a result of a successful GGPP Stage 2 Demonstration;
  • Working cooperatively towards evaluating and implementing other low-carbon technologies

Globally, Alcoa has achieved a 44% reduction in greenhouse gas emissions since 1990. Alcoa Anglesea Power Station Manager Stephanie Pearce said Alcoa’s Victorian Smelting Operations have reduced direct greenhouse gas emissions by over 60% in the same period and the MOI with Greenearth Energy is in line with Alcoa’s ‘big picture’ response to climate change.

“In Australia, alongside our significant greenhouse gas reduction efforts, we have enabled the establishment of critical energy infrastructure and co-generation facilities, and successfully piloted and commercialised carbon capture and waste reduction technologies which significantly reduce greenhouse gas emissions in the ammonia, cement and brick industries,” she said.

“The Portland Smelter facilitated the grid connection of the Portland wind farm and our product, aluminium, is 100% recyclable. In Western Sydney, we operate Australia’s largest aluminium recycling facility and in doing so, avoid the generation of over one million tonnes of carbon emissions each year.

“Our effort to be part of the solution to climate change has never stopped at the gates to our operations. We are a proud supporter of the greenhouse gas reductions and adaptation efforts of organisations like Greening Australia and Sustainability Victoria.”

Greenearth Energy Managing Director Mark Miller said the MOI with Alcoa may be the catalyst for overcoming some of the most significant hurdles still ahead for the GGPP. It represents a significant and substantial development for the GGPP and a potential pathway from the preliminary planning stage through Stage 1 exploration, Stage 2 demonstration and grid connection.

“Our two organisations have discussed a potential site within Alcoa’s mining lease area that has all the necessary characteristics for the GGPP exploration stage. This matter is now being progressed with good support from the Department of Primary Industries and in consultation with other government agencies,” Mr Miller said.

“Geothermal energy is being increasingly recognised as having the potential to deliver zero emissions, reliable and importantly base load renewable energy generation.

“Alcoa has an exemplary record in energy efficiency and management and made it clear to us from the outset that it is very keen to see the development of base load renewable technology in Australia. We are delighted to have reached this stage in our discussions with Alcoa and look forward to a relationship that has the potential to deliver benefits to all Victorians.

“We view this MOI with Alcoa as a further endorsement of the potential that our project has in delivering zero emissions, base load renewable energy to our state. The support by Alcoa coupled with the Commonwealth and State Governments’ support of our flagship geothermal project can only further enhance our project.”

Ms Pearce and Mr Miller said Alcoa and Greenearth Energy will be undertaking a series of key stakeholder engagement activities and briefings as a result of signing the MOI, but detailed discussions would remain confidential.

There is much work ahead, but Alcoa looks forward to sharing new information as it becomes available and as we approach and achieve major milestones.
