Wartsila will supply a 300MW energy storage system to Zenobe for a project in Kilmarnock, Scotland.
The 600MWh battery energy storage system (BESS) will be supplied under an engineered equipment delivery (EEQ) contract to Zenobe.
This is the second energy storage system Wartsila is delivering to Zenobe and it will be one of the largest in Scotland to date.
The order was booked to the company’s order intake in January 2024 and the energy storage system is expected to be operational by the end of 2025.
The project will be delivered under Great Britain’s National Grid’s NOA Stability Pathfinder programme, which aims to cost-effectively address stability issues in the electricity system created by the increased adoption of intermittent renewable generation.
The energy storage system will help grid operators to better balance supply and demand and ensure that the country’s abundant wind generation is not wasted.
Wartsila energy storage & optimisation vice president Andy Tang said: “This project brings Wartsilä’s portfolio of energy storage assets in the United Kingdom over 2GWh.
“We are committed to assisting customers in the UK reach their national decarbonisation targets through innovative energy storage solutions.”
This project follows the announcement in February 2023 of a 200MW / 400MWh energy storage system Wartsila will deliver to Zenobe in Blackhillock, Scotland.
The Blackhillock site is on track to be operational by autumn 2024.
