ARENA: Funding 30MW SA battery to demonstrate how energy storage strengthen the grid.

The Australian Renewable Energy Agency (ARENA) will help fund $30 million for a large-scale energy storage system. This project is designed to demonstrate how energy storage can strengthen the grid and potentially lower energy prices.

(ESCRI) Energy Storage For Commercial Integration Phase 1 consisted of a study into the potential for energy storage to benefit the South Australian network.

“The (ESCRI) battery would make an important contribution to security and reliability in the energy generation in SA,” ARENA CEO said.

“This is also the first large-scale grid-connected battery to be designed, built and commercially operated in Australia. This is largely planned with private investment from energy providers,” ARENA CEO Frischknecht added.

“It may not be the biggest battery in the world, but pound-for-pound it will pack a big punch in demonstrating how utility-scale storage can contribute to a stronger South Australian energy network.”

The listed the specific benefits of this project by Frischknecht:

Supplying fast frequency response, which helps balance the electricity network, particularly in the increased levels of renewable energy generation. This capability will also be used to help reduce operating constraints on the Heywood interconnector. With Victoria which, in turn, has the potential to place downward pressure on wholesale energy prices in SA.

Providing contingency power for the Dalrymple service area during a loss of supply. The islanded battery will work together with the existing 90MW Wattle Point wind farm. Rooftop solar PV in a microgrid will provide local backup supply until connection to the grid is restored.

Demonstrating that utility-scale batteries can aggregate and “value stack” multiple revenue streams and deliver both regulated network services and competitive market services, thereby encouraging other energy developers to enter the market with battery projects.
