Ørsted to Build 300-MW Battery for Hornsea 3

• Ørsted A/S invests in cutting-edge battery storage for Hornsea 3 offshore wind farm, leading the way in renewable energy innovation.

Danish clean energy company Ørsted A/S has made a final investment decision to build a 300-MW/600-MWh battery energy storage system for its Hornsea 3 offshore wind farm project in the UK. The battery, a Tesla system, will be one of the largest in Europe and is expected to be operational by the end of 2026. This investment is part of Ørsted's strategy to balance its offshore wind power generation with grid-balancing technology.

The battery will help maximize the potential of renewable energy by storing excess energy when demand is low and releasing it back into the system when needed. Ørsted currently has 660 MW/1,850 MWh of storage projects in operation or under construction in the UK and US, with a pipeline of over 2 GW across multiple countries. The company's plan for the Hornsea 3 project was approved by the South Norfolk Council in early 2023, with the final investment decision announced in December 2023.
