New grid-scale battery powering South Australia

A new grid-scale battery is now up and running at the Dalrymple substation on South Australia’s Yorke Peninsula.

Construction of the 30 MW / 8 MWh grid-scale battery was completed in April 2018. The $30 million Energy Storage for Commercial Renewable Integration (ESCRI) project has been commissioned and tested and is now live and connected to the National Electricity Market (NEM).

Transmission provider ElectraNet developed and owns the ESCRI battery, which was built next to, and connected to their Dalrymple substation. AGL will operate the battery under a long term lease agreement.

ElectraNet chief executive, Steve Masters, said the new battery is the first large-scale battery in the NEM to provide both regulated network services and competitive market services to maximise value from its operation.

“On average, it can provide backup power to 4500 customers in the Dalrymple service area for 2-3 hours while connection to the grid is being restored,” Masters said.

On behalf of the federal government, the Australian Renewable Energy Agency (ARENA) provided $12 million in funding towards the construction of the project.

ARENA acting CEO, Nicola Morris, said that the completion of the ESCRI battery has already helped inform the development of further battery projects around Australia.

“The ESCRI battery will provide storage to support renewable generation and will provide  fast frequency response to stabilise the grid,” Morris said.

“The battery will also work with the 90 MW Wattle Point Wind Farm, and local rooftop solar, to provide contingency power to the households and businesses on the Yorke Peninsula if a power outage occurs.

“It is clear that grid scale energy storage has a role to play our future energy mix. ESCRI demonstrates that utility scale batteries can deliver a range of market services and back up power when it is needed.”

ARENA has funded four grid-scale batteries, including two batteries recently commissioned in Western Victoria and Infigen’s Lake Bonney battery currently under construction in South Australia.
