In a significant advancement for renewable energy in the UK, the Larks Green Solar and Battery Energy Storage System (BESS) project, led by Cero Generation, has successfully connected to the UK’s National Grid transmission network. This marks the first time a co-located solar photovoltaic (PV) and battery storage system in the UK has been integrated into the high-voltage transmission network.

The 49.5 MW / 99 MWh battery storage facility, provided by Canadian Solar's subsidiary e-STORAGE, has been key to the grid connection of the Larks Green solar project in Itchington, England. This project combines a 70 MWp solar system and energy storage, developed together with Enso Energy. Its innovative design allows stored energy to be injected into the grid at times of high demand, improving grid reliability, reducing energy costs and reducing dependence on fossil fuels.

Beyond clean energy production, the Larks Green project also demonstrates a commitment to biodiversity. The site is designed to deliver a net biodiversity gain of 25% through a series of environmental measures, including reinforcing nearly 10 kilometers of hedgerows and planting new wildflowers across 9 hectares. This green initiative aligns with the UK’s goals to support local ecosystems alongside renewable energy advancements.

This energisation of the BESS comes after the completion of the 70MW Larks Green solar project in Gloucestershire in April 2023, which was among the first standalone solar projects to connect to the grid.

The successful grid connection of Larks Green underscores the UK’s growing commitment to renewable energy innovation and marks another major step forward in achieving a sustainable, resilient energy future.
