The Energy Observatory is the Barcelona Energy Agency unit responsible for planning and monitoring the energy situation in the city. The Energy Observatory obtains information about energy and publishes a regular energy assessment, aside from planning specific short-term initiatives regarding the city’s energy and monitoring these initiatives.

It is necessary to carry out constant updates of the information in order to manage the city’s energy reality. Having data available and the evolution of this data enables us to rate the energy policies that are implemented in the city and devise lines of action for the future.

Barcelona assessment

Barcelona consumes 15,896 GWh/year and only about 16.9 GWh of this is generated by renewable and residual energy. To reduce the overall average consumption of 9.81 MWh per inhabitant, the City Council wants to minimise the city’s dependence on energy from fossil fuels and promote the local generation of renewable energy, connected to the power grid, to reduce CO2 omissions and create a new and more sustainable energy model.

Currently, the city generates 6,577 GWh/year of electricity locally, which represents 100% of electrical energy consumed in Barcelona. But as only 1% of this energy is renewable, the challenge is twofold: to generate more energy locally that is clean energy.

What can we discover from this assessment?

All this data is provided in the new 2018 Barcelona Energy Assessment. It should be noted that the data can be viewed by district, the impact of energy consumption in terms of GHG emissions, the main cause of climate change, and the trend in emissions in Barcelona in recent years.

It also includes the City Council Energy Assessment, which represents 3.6% of overall consumption in the city. This consumption has remained more or less stable in recent years, despite the increase in the number of municipal facilities and services. This is due to a variety of energy saving initiatives in an extensive range of areas such as buildings, facilities, lighting and vehicle fleets, among others.


Energy consumption in Barcelona. Sankey diagram

Below is the energy Sankey diagram for Barcelona. This type of diagram allows the quick visualisation of how energy consumption is distributed across the city by sectors and sources, which is renewable and which is not, and what relationship exists between them.

Renewable energy generation in Barcelona

Renewable energy generation in Barcelona is focused mainly on thermal solar energy and photovoltaic solar energy. The following charts show the development of their introduction in the city.
