The Mount Piper Battery Energy Storage System (BESS) project, proposed by EnergyAustralia, would comprise the development of 500 megawatt / 2,000 megawatt hour BESS. The project would be located approximately 25 kilometres from Lithgow in NSW.
Proposed infrastructure components include:
- battery modules
- a substation comprising two transformers
- other high voltage infrastructure, and
- ancillary infrastructure features including temporary construction and laydown areas, extension to existing internal access roads and installtion of a concrete platform for the BESS modules.
Project construction may be staged depending on market conditions and site constraints, with both stages comprising 250 MW / 1,000 MWh.
