Danish utility Ørsted has committed to add a 300MW / 600MWh battery system to its 2.9GW Hornsea 3 offshore wind project in the UK.

The company has taken a final investment decision to add a Tesla Megapack battery storage system to the offshore wind project’s onshore converter station in Swardeston near Norwich.

The battery system is due to be operational by the end of 2026 and Hornsea 3 is scheduled to be fully commissioned by the end of 2027.

This expands Ørsted’s portfolio of operational and construction-stage storage projects to 660MW / 1,850MWh. It also has a 2GW pipeline of storage projects in the UK, Ireland and the US.

Duncan Clark, head of UK and Ireland in Ørsted, said: “The battery will help ensure that renewable energy is used in the best possible way by storing it when demand is lower and then releasing it back into the system when it’s really needed, thereby maximising the potential of renewable energy whilst providing increased energy security and value to consumers.”

Mike Snyder, senior director of Megapack at Tesla, said: “Tesla is excited to be part of this industry-leading project with an exceptional partner. This project demonstrates the value and flexibility of Tesla’s best-in-class power electronics, providing enhanced grid stability and enabling more renewables on the grid.”
