France-based renewable energy firm Neoen has finalised a consortium of Doosan Heavy Industries and Construction and its subsidiary, Doosan GridTech, to build the Capital Battery.

The 100MW/200MWh project will be the Australian Capital Territory’s (ACT) largest standalone battery storage system.

Under the agreement, the consortium has agreed to offer engineering, procurement and construction (EPC) services for the battery.

It will also provide operation and maintenance services for the project over a period of 20 years.

The Capital Battery has 627 battery units and is expected to become completely operational by mid-2023.

Doosan GridTech chief operating officer Wonyoung Ahn said: “We are honoured that Neoen has chosen Doosan to deliver its signature energy storage system in the ACT.

“The Capital Battery represents a big step in building our momentum to provide high megawatt grid-scale battery storage systems.

“Once again, we are demonstrating that competitively priced systems deployed alongside advanced and flexible control platforms are winning propositions for global renewable developers.

“Turnkey delivery provides simplicity of purchase and a higher degree of short-term risk management.”

Doosan’s lithium-ion battery solution will be deployed at the Capital Battery project.

The solution is expected to provide grid stability for the electricity network of southern New South Wales while supporting the ACT’s shift to total carbon neutrality by 2045.

Doosan GridTech’s Intelligent Controller will manage energy arbitrage, fast frequency response and ancillary services for the project.

The storage control and optimisation system is built on open standard interfaces and has the capability to offer synthetic inertia or black start services in the future.

The system has been designed to respond to complex schedules and intricate operating modes using the latest power system intelligence integrated into an energy management platform.

Earlier this month, Neoen began operations at its 300MW/450MWh Victorian Big Battery in Geelong, Australia.
