European Energy Launches 68 MW Solar-Plus-Storage Project in Cornwall

European Energy has commenced construction of the 67.96 MW Indian Queens hybrid solar and battery storage project in Cornwall, United Kingdom, integrating a 95 MWh co-located battery energy storage system (BESS) to support grid flexibility and renewable power generation. 

Construction started in May 2026 and is anticipated to last for nearly a year, with grid connection targeted for the first half of 2027. The project includes a 67.96 MW solar power facility expected to generate about 60 GWh of electricity annually. It adopts a co-located solar-plus-storage approach already proven in the region, aimed at improving operational efficiency and supporting smoother grid integration. A long-term offtake agreement has also been secured for the solar output, strengthening revenue certainty and improving the project’s financial viability.

The project further incorporates a co-located BESS with a capacity of 95 MWh, enabling more efficient power management, greater flexibility in energy delivery, and participation in ancillary service markets. European Energy is executing the development under a full engineering, procurement, and construction (EPC) model, covering both the solar facility and the integrated battery storage system. This unified approach helps streamline civil and electrical works, optimize grid connection infrastructure, and improve coordination between the generation and storage components. The EPC structure is also intended to strengthen construction oversight, maintain quality standards, and support reliable long-term operational performance across the project lifecycle.
