Kwinana Battery Energy Storage System Stage 2

Planning WA's energy future

Kwinana Battery Energy Storage System Stage 2 (KBESS2) will be Synergy's second lithium-ion, large scale battery energy storage system in the SWIS.

In delivering KBESS2, our Future Energy Business Unit is working on a range of innovative, industry-leading delivery concepts to create additional utility scale energy storage solutions for the SWIS.

This project is crucial to support the closure of our coal-fired power stations, in line with the State Government’s announced retirement schedule to achieve its 2030 emissions reduction targets. Adding this volume of battery storage to the grid is required for large-scale renewable generation assets to be able to be connected to the network.

Location

  • The KBESS2 battery is next to KBESS1 at the existing Kwinana Power Station site, which was successfully decommissioned in September 2023.
  • The site is within the suburb of Naval Base on the Swan Coastal Plain, situated approximately 30km southwest of Perth’s central business district, 17km south of Fremantle and 5.5 kilometres northwest of the Kwinana town centre.
  • The site is within one of WA’s most important industrial areas. The land is comprised within the local government areas of Cockburn, Kwinana and Rockingham, within the Kwinana Strategic Industrial Area.
  • KBESS2 is connected to the 330kV Western Power transmission system via the existing substation which was constructed 500m from the KBESS1 facility.

Layout and size

  • KBESS2 consists of 8 power groups with 288 battery units across the facility. There are additional areas dedicated for stormwater/firewater runoff management and an operations and maintenance facility.
  • KBESS2 is approximately the size of 4 soccer fields. The facility has a power capacity of at least 200MW and storage capacity of at least 800MWh.

Progress

  • KBESS2 commenced testing in September 2024 and is targeting commercial operation by end of 2024.
  • Construction activity will continue in parallel until March 2025 for non-critical operational components.
