AMPYR proposes to develop the Wellington Battery Energy Storage System. The project consists of a battery energy storage system (BESS) with a capacity of 500 megawatts (MW) / 1,000 megawatt-hours (MWh), with associated infrastructure. The project will connect to the Wellington TransGrid substation via a 330-kilovolt (kV) overhead or underground transmission lines.
The project is being delivered in two stages.
- Stage One: 300 MW / 600 MWh, and
- Stage Two: 200 MW / 400 MWh.
The project would be located approximately three kilometres north-east of Wellington, in the Central West of New South Wales, within the Dubbo Regional Council local government area.
