The Deer Park BESS (previously Melbourne Grid Battery) is a critical piece of energy infrastructure that will enable greater system strength and reliability for Victoria, supporting the state's energy transition.

The Deer Park Battery Energy Storage System (BESS) has been developed by Lumea, and is now under development with Akaysha Energy. The BESS will be located at the Deer Park Energy Hub and substation, a key source of electricity supply for metropolitan Melbourne. It will be one of the few batteries in the National Electricity Market to be located on the load side, close to a source of high energy demand.

Lumea, which sits as part of Transgrid group, has a substantial land asset at Deer Park with available bays and adequate network capacity. Transgrid is the transmission network service provider for NSW and the ACT, as well as a declared transmission system operator in Victoria.

Australia’s energy transition is seeing significant change in the energy landscape in the shift to renewable energy, and the infrastructure that is required to get there. Batteries are playing an important role supporting this transition.
The Deer Park BESS will also optimise the use of renewable energy generation in Victoria and across the National Energy Market by providing energy storage services and supplying energy when most needed, and may also offer services to support grid reliability and system support.
