Tender Description
Overview
The Wellington Battery Energy Storage System (BESS) will store excess renewable energy ready for use by homes and businesses during peak times. BESS projects play an important role in the future electricity system.
The project is in the Central West Orana Renewable Energy Zone three kilometres northeast of Wellington. The project will be delivered in two stages. Construction of Stage 1 (300MW / 2 hours) will start mid-2025, finishing early 2027. Plans for construction of Stage 2 are ongoing, but construction is likely to follow 12 to 18 months behind Stage 1.
The existing Wellington substation is very strategically located within the NSW energy grid. The output from both stages of the Wellington Battery represents the demand from over 60,000 home
