TagEnergy has closed financing for the 150 MW/600 MWh Golden Plains Wind Farm battery energy storage system (BESS) in Victoria. The project will use 168 Tesla Megapack 2XL battery containers and is being built by Consolidated Power Projects Australia (CPP). Construction at Golden Plains Wind Farm BESS will start in early 2026 ahead of commissioning targeted for mid-2027.
Project Overview
Renewables developer TagEnergy also refers to the BESS installation as a strategic complement to the Golden Plains Wind Farm. The wind farm itself is one of the largest onshore renewable energy developments in the southern hemisphere, having being awarded in Australia’s CIP Tender 4 this year. The battery storage installation will help smoothen intermittency and provide system strength services to Victoria’s 500 kV transmission network. The system will also deliver flexible capacity during peak demand periods.
In addition to the technical and infrastructural significance that the financing milestone brings to the project, it also comes at a time when Australia’s grid increasingly needs storage to support rising renewable penetration. TagEnergy also recently signed a 15-year, 105MW, four-hour virtual toll agreement with Snowy Hydro for its 150MW/600MWh BESS in western Australia.
