Europe’s Largest Battery Storage System, Powered By Tesla, Starts Running

The Pillswood Project, Europe’s biggest battery energy storage system, has been finally been fired up near Hull in Yorkshire. 

Developed by Harmony Energy Limited and running on a Tesla two-hour Megapack system, the facility is said to be able to store up to 196 MWh of electricity in a single cycle—or enough energy to power 300,000 UK homes for two hours. 

According to the firm, the power system will bring “critical balancing services” to the country’s electricity grid network, while allowing for fossil fuels to be replaced with eco-friendly, renewable sources of energy. 

Next year, the adjacent Dogger Bank, the world’s largest offshore wind farm, will go online, sharing the same connection point with Pillswood Project to maximize the efficiency of the wind farms, such as limiting the amount of time it will need to be switched off.

Originally, the facility had been scheduled to go live over two phases in December 2022 and March 2023, but the timeline was sped up so that it could begin this month, just in time to support the nation in its efforts to power households over the energy-intensive winter period. 

“Battery energy storage systems are essential to unlocking the full potential of renewable energy in the UK, and we hope this particular one highlights Yorkshire as a leader in green energy solutions,” says Peter Kavanagh, Harmony Energy Director.
