Boosting Reliability on Lower Yorke Peninsula

ElectraNet’s 30 MW large-scale battery at Dalrymple substation demonstrates how energy storage can strengthen the grid and improve reliability for the lower Yorke Peninsula.

It is the first certified indoor battery in Australia that is connected to the energy grid and the first large-scale battery in the National Energy Market (NEM) to provide both regulated network services and competitive market services.

The 30 MW / 8 MWh battery energy storage system is next to, and connected to, ElectraNet’s Dalrymple substation, seven kilometres south-west of Stansbury.

It works with AGL’s existing 90 MW Wattle Point Wind Farm and rooftop solar PV to provide back-up power in the event of any interruption to supply from the grid until the grid is restored.

The battery provides both regulated network services and competitive market services.

The regulated network service benefits include:

  • improved reliability for the southern Yorke Peninsula region by supplying power for 2-3 hours following the of loss of transmission supply, or longer if there is sufficient renewable generation from Wattle Point windfarm and/or local PV
  • fast frequency response to reduce Heywood interconnector constraints and improve power system security by quickly injecting power into the grid following a disturbance

The project was part funded by the Australian Renewable Energy Agency (ARENA).

The battery facility was constructed by Adelaide company Consolidated Power Projects who worked with international power company ABB and battery provider Samsung to deliver the project.

Construction commenced in October 2017 and the site was energised on 30 April 2018. Commissioning and testing occurred until late 2018 and ElectraNet handed over commercial operation of the battery energy storage system to AGL in December 2018.
