Origin Energy is constructing a new grid-scale battery on the site of the Eraring Power Station, near Lake Macquarie. The battery will have a capacity of 460 megawatts (mw)/920 megawatt hours. The Eraring Big Battery will use existing transmission infrastructure and will progressively commence operations over three phases. The project has the potential to be expanded to 700 mw in the future.

PROJECT HISTORY
| Jan 2021 | Expressions of Interest opened for the project. Origin also lodged an enquiry with Transgrid to connect the proposed battery via the Eraring substation to the national grid. Origin Energy will require final Board approval to progress the project once a preferred supplier is selected and permits are obtained. |

| Feb 2022 | Origin Energy announced it would bring forward its planned closure of the Eraring Power Station by seven years to 2025. Origin also confirmed it is continuing to progress the battery project on the Eraring site, but reduced the expected capacity of the facility from 2,800 megawatt-hours (MWh) to 1,400 MWh. |
| May 2022 | The NSW Government provided planning approval for the development of the 700-megawatt, 1,400-megawatt-hour Eraring Big Battery. |
