Barcelona is moving closer to meeting its renewable energy goals for 2027, with the city aiming to reach 381 photovoltaic installations by that year — three times more than it had in 2023.
According to municipal projections, this expansion would boost installed capacity to 19,192 kW, equivalent to the annual energy consumption of around 10,430 households. Such growth could save an estimated 8,600 tonnes of CO₂ emissionseach year.
Currently, Barcelona has around 268 municipal solar installations, delivering close to 11,500 kW, enough to supply approximately 6,200 homes annually. An additional 54 projects under construction will soon add 2,600 kW, bringing the total capacity to over 14,000 kW — already achieving 85% of the city’s 2027 target.
By 2027, the city expects 284 rooftop solar sites, 68 in public spaces, and 29 on building façades and walls. This marks a dramatic increase compared to 2023, when only 177 installations were in place, generating 5,849 kW — barely a third of the target.
In just two years, Barcelona has activated 91 new solar parks, doubling its generation capacity. Over the next two academic years, the city will need to add 113 more installations, with 54 already underway. These new sites will contribute roughly 7,600 additional kWp, keeping Barcelona on track in its green energy transition.
