Renewco, Atlantica join hands on 2.2 GW standalone BESS rollout in Spain

UK-headquartered renewable energy developer Renewco Power and Atlantica Sustainable Infrastructure, an infrastructure company focused on renewable energy, have entered into an agreement to develop up to 2.2 GW of greenfield standalone battery energy storage system (BESS) projects across Spain.

Last year, Renewco launched a process to find an investment partner for its diversified greenfield BESS portfolio of 16 projects which would connect to select transmission substations across Spain, subject to the forthcoming grid capacity auctions planned by the Spanish government.

The Spanish government has recently signalled that BESS projects would have a fast track or special grid connection route due to the urgent need for building BESS capacity in the country.

Renewco will develop the projects to ready-to-build (RtB) status, with Atlantica then set to build and manage the portfolio. The 2.2 GW pipeline is still subject to securing grid connection.  

Since launching in 2021, Renewco has built a team of over 50 renewables specialists, rapidly developing its 7 GW pipeline of solar, wind, BESS and green hydrogen projects across the UK, Spain, Italy and the US.

Atlantica has a team of 1,400 employees and is present in 12 countries mainly in North America, Europe and South America. The company has 2.2 GW of aggregate renewable energy installed generation capacity in operation, including 682 MW of solar capacity in Spain alone. Its pipeline stands at around 3 GW of renewable energy and 12 GWh of storage of which 93% are located in North America and Europe.
