Voltwise has signed and closed a transaction to acquire the Battery Energy Storage System (BESS) division from SMS, which brings 460 MW of BESS assets in operation and under construction across the UK.
The acquisition sees Voltwise significantly increase its UK footprint, marking a key step in the company’s growth strategy to become a leading, BESS-focused, independent power producer across Europe.
