Solar developer Lightsource BP has energised its first UK-based battery energy storage system (BESS) – the first of its global multi-gigawatt pipeline.

The two-hour duration 25MW/50MWh Tiln BESS is co-located with Lightsource BP’s 61MWp solar farm situated in Lincolnshire, a region of the UK that has seen growing interest for large-scale solar-based national significant infrastructure projects (NSIPs).

Lightsource BP disclosed that the solar and battery assets share grid connection infrastructure and will participate in both traded markets and the provision of ancillary services. The developer did not confirm who had supplied the BESS for the project.

Miguel Vega, director of business development, EMEA, at Lightsource BP suggested that energy storage can “help renewable energy take a central role in the world’s electricity network”, adding that it is “imperative that renewables, with solar at the forefront, are established as the backbone of low-carbon energy systems”.

It has been a busy few months for Lightsource BP, with the company fully acquired by oil and gas giant BP in late November 2023 via the acquisition of the remaining 50.03% stake.
