Municipal photovoltaic energy generation map
Municipal buildings and facilities, as well as other infrastructure such as public lighting and traffic lights, account for a significant proportion of total municipal energy consumption. It’s therefore crucial to generate as much energy as possible from renewable, local sources, expanding and developing new installations to contribute to climate neutrality goals and serve as an example for city residents.
Given that Barcelona’s main renewable resource is the sun, increasing photovoltaic self-consumption will be key to meeting the city’s decarbonisation and climate neutrality goals for 2030, as outlined in its Climate Plan.
Energy generation in cities is typically associated with rooftop installations, but urban public spaces also offer great potential for installing these systems.
In Barcelona, there are currently 176 municipal buildings with photovoltaic generation systems, 19 energy-generating pergolas in city parks and squares, and 16 installations on walls, including party walls.
The “Accelerating photovoltaic energy generation in Barcelona” government measure promotes the use of rooftops and public spaces to generate energy, both in the public and private sectors, and outlines the actions required to make self-consumption part of daily life.
How much energy does Barcelona generate?
In 2024, the city had 19 public pergolas, 16 walls (including party walls) and 176 municipal buildings with photovoltaic installations, with a total capacity of 8,750 kWp and generation of 10,600 MWh, equivalent to the electricity consumption of over 4,600 households and representing a saving of 8,818 tonnes of CO2-eq emissions.
This map shows where these generation facilities are located, how much energy they generate, and the savings in energy consumption and CO2 emissions they achieve.
