Sunnica Solar-plus-Battery Energy Storage System
The 50MW lithium-ion battery energy storage system is directly connected to National Grid’s high-voltage transmission network at the Kemsley substation in Kent and will provide essential flexibility to support the integration of more renewables and future-proof the UK’s electricity system.
The Penso Power-Hams Hall Battery Energy Storage System is a 350,000kW lithium-ion battery energy storage project located in Hams Hall, North Warwickshire, England, the UK. The rated storage capacity of the project is 1,750,000kWh. The electro-chemical battery storage project uses lithium-ion battery storage technology.
As of June 2024, the UK’s operational battery storage capacity was 4.6GW, so the new projects represent a roughly 7% increase nationwide. The UK’s total battery storage is expected to increase to 7.4GW by the end of the year. The technology will be needed if Labour is going to meet its target of decarbonising the UK’s energy generation by 2030.
The UK is known to be one of the world’s most active markets for battery energy storage. In 2022, the market saw a record 800 MWh of new storage capacity being added. This took the UK’s operational energy storage capacity to 2.4 GW and 2.6 GWh, spread across more than 160 sites.
The four longer-duration energy storage demonstration projects will help to achieve the UK’s plan for net zero by balancing the intermittency of renewable energy, creating more options for sustainable, low-cost energy storage in the UK.
