Neoen has been awarded a 250 MW grid services contract by AEMO, the services will be provided by Neoen’s future 300 MW Victorian Big Battery, set to become one of the world’s largest batteries.

Neoen, one of the world’s leading and fastest-growing producers of renewable energy, has announced that it has been awarded a 250 MW grid services contract by the Australian Energy Market Operator (AEMO). The services will be provided by Neoen’s future 300 MW Victorian Big Battery, set to become one of the largest batteries in the world. The battery storage facility will be located next to Moorabool Terminal Station in Geelong, Victoria. It will be delivered in collaboration with Tesla, using its Megapack technology, and network partner AusNet Services.

This System Integrity Protection Scheme (SIPS) contract with AEMO will run until 2032 and is the result of the SIPS 2020 procurement process initiated by the Victorian Government. It will unlock up to an additional 250 MW of peak capacity on the existing Victoria to New South Wales Interconnector (VNI) over the next decade of Australian summers. Under the contract, the battery will provide an automatic response in the event of an unexpected network outage, providing AEMO with an additional means of ensuring grid stability. Batteries are genuinely well suited to perform this service because they can respond in a fraction of a second. The battery will also participate in the National Electricity Market and support increased penetration of renewables in Victoria through network services such as fast frequency control.

Hon Lily D’Ambrosio MP, Minister for Energy, Environment and Climate Change said: “By securing one of the biggest batteries in the world, Victoria is taking a decisive step away from coal-fired power and embracing new technologies that will unlock more renewable energy than ever before.” Neoen World’s Largest Batteries 

The Victorian Big Battery will help to modernise and stabilise the grid in Victoria and will be instrumental in helping the State reach its objective of 50 percent renewables by 2030. Independent analysis shows that for every $1 invested the battery will deliver more than $2 in benefits to Victorian households and businesses. The savings that big batteries can provide to energy consumers are now well-established, with independent reviews demonstrating that Neoen’s Hornsdale Power Reserve has delivered more than $150 million AUD in savings in its first two years of operation.

Louis de Sambucy, Neoen Australia’s Managing Director said “We are delighted to have won the SIPS contract and would like to thank AEMO and the Victorian Government for placing their trust in us. We are looking forward to working once again with Tesla and AusNet to deliver this world-leading battery storage facility over the coming months. We are extremely proud to be launching a project of this scale and innovation in support of Victoria’s clean energy transition.”

The battery is targeted to be operational by the end of 2021.
