Barcelona triples its municipal solar potential and achieves one of the main goals in the Climate Plan
The city makes the most of everyday outdoor spaces such as pergolas and shade structures to generate green energy.
The city has now achieved one of the main goals of the Climate Plan: to triple the solar power generation of municipal facilities. This leap forward in creating local green energy was possible thanks to the installation of solar panelling on rooftops, in public spaces, walls and party wall and other city infrastructures.
With 381 photovoltaic installations planned for 2027, Barcelona will reach 19.192 kWp of installed power capacity, able to generate the equivalent to the annual energy consumption of 10,430 homes. That means a saving of over 8,600 tonnes of CO2 every year.
This goal is part of the government measure introduced a year and a half ago to drive the energy transition in the city. The measure involves making the absolute most of the space available, such as the rooftops of municipal buildings, pergolas, walls and façades to generate renewable energy without these spaces losing their purpose or function.
Accelerated growth in just two years
The city has tripled its municipal solar power potential since 2023 and, in just two years, has put 91 new installations into operation, reaching a total of 268 active facilities with 11.449 kWp of power capacity installed. This acceleration in the generation of solar power represents a solid step towards a more self-sufficient and sustainable Barcelona, reducing dependency on external and pollutant sources of power, also strengthening the city’s commitment to the energy transition and the fight against climate change.
Where has solar panelling been installed?
Numerous projects have been carried out, demonstrating the move in favour of solar generation in all areas of the city. Between 2024 and 2025, solar panels have been installed on pergolas in public spaces such as Pl. Anna Lizaran in L’Eixample, in Marina del Prat Vermell in Sants-Montjuïc and Via Trajana in Sant Andreu, as well as at various points around Sant Martí.
Self-generating systems have also been installed at sports facilities such as the CEM Picornell, the CEM La Guineueta and the Campillo de la Virgen courts. Community centres, elderly people’s centres, libraries, municipal offices, mobility infrastructures such as the Ronda Litoral and iconic markets such as those in Sants and Sant Antoni have also been part of the initiative, showing that solar energy can be integrated into all sorts of public facilities without them losing their functionality or purpose, improving the city’s energy efficiency.
Barcelona will continue to promote self-consumption and shared power generation, integrating storage systems and promoting formulas such as energy communities, which help people to play and active part in the energy transition.
