Boosting Reliability

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

The 30 MW / 8 MWhr battery energy storage system will be built next to, and connected to, ElectraNet’s Dalrymple substation, seven kilometres south-west of Stansbury. It is expected to be ready for full operation in the National Electricity Market by May 2018.

It will work 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 will provide 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 approximately 2 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

Once completed, ElectraNet will lease the battery to AGL who will operate it to provide competitive market services.

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

Construction has been awarded to Adelaide company Consolidated Power Projects who will work with international power company ABB and battery provider Samsung to deliver the project.
