UK-based Renewco Power and Atlantica Sustainable Infrastructure have partnered to develop up to 2.2GW of standalone battery energy storage system (BESS) projects across Spain.
Renewco will progress the projects to a ready-to-build stage, after which Atlantica will handle the construction and management of the portfolio.

The 2.2GW pipeline is dependent on obtaining grid connection approval.
Last year, Renewco began searching for an investment partner for its diversified greenfield BESS portfolio, which comprises 16 projects intended to connect to select transmission substations across Spain, pending the national government’s forthcoming grid capacity auctions.
The Spanish Government has indicated that BESS projects might receive a fast-track or special grid connection route due to the urgent need for increased BESS capacity in the country.
Since its inception in 2021, Renewco has assembled a team of more than 50 renewable specialists, rapidly advancing its 7GW pipeline of solar, wind, BESS, and green hydrogen projects across the UK, Spain, Italy, and the US.
Renewco’s presence in Spain includes a development pipeline of wind, solar, BESS, and green hydrogen projects.
With a workforce of 1,400 employees, Atlantica operates in 12 countries, primarily in North America, Europe, and South America.
It has 2.2GW of aggregate renewable energy installed generation capacity in operation and a strong presence in Spain with 682MW of solar installed capacity. Atlantica plans to continue expanding in Spain.
The company also has a pipeline of approximately 3GW of renewable energy and 12GWh of storage, with 93% located in North America and Europe.
Renewco chief commercial officer Alp Karli said: “We are delighted to start this partnership with Atlantica, which we believe is set to have a positive impact on Spain’s energy infrastructure.
“For our BESS development operations across Spain, we are looking forward to utilising our experience in the UK and other markets, which are ahead of Spain in deploying BESS in its grid infrastructure to enable the renewables transition.”
