Reduce the energy poverty of the vulnerable population in Barcelona

by generating electricity from

photovoltaic solar energy


How to distribute the surplus of solar energy generated to alleviate the energy poverty of the vulnerable population in Barcelona?


DataCity Lab is an urban innovation program that brings together corporations and technological companies to develop innovative solutions to the challenges faced by municipalities, through the use of data. The program in Barcelona is promoted by the Commissioner for Digital Innovation, Electronic Administration and Good Governance of the Barcelona City Council in collaboration with the Municipal Data Office and BIT-habitat.


This challenge focuses on a double objective of the Barcelona City Council, within the framework of the Climate Plan 2030 and the Declaration of Climate Emergency, which are the reduction of energy poverty and the increase in solar energy generation at the urban level.

The challenge counts with the participation of the Municipal Data Office, the ​​Social Rights Department and the Energy and Environmental Quality Direction of the Barcelona City Council, ACCIONA's participation as a collaborating corporate and, lastly, the Data Science Department of the University of Barcelona as academic partner.

of the population suffers from energy poverty in Barcelona*

* The 2030 Climate Plan of the Barcelona City Council defines Energy Poverty as the inability of a household to satisfy the basic energy needs of its members, such as keeping the home in conditions of air conditioning suitable for health (from 18ºC- 20ºC in winter and 25ºC in summer).

10.6% of the population of the city of Barcelona is in a situation of Energy Poverty [1] while Barcelona has a high potential for solar energy generation.


A possible solution to reduce the energy poverty of vulnerable groups would be to obtain surplus electricity generation from the installation of solar panels and redistribute the energy generated to the aforementioned groups. In order to analyse the feasibility of this approach, it is necessary to take into account the current technical and legal limitations. One of the main limitations imposes that generation and consumption points be connected in low voltage and at a distance of less than 500 meters [2].


Taking these limitations into account, the DataCity project will analyse three superblocks of the city of Barcelona: Poble Nou, La Marina y Vila de Gràcia


We are looking for technological companies that have expertise in data analytics related to the energy sector and that can estimate and simulate in which areas of the chosen superblocks it would be viable to supply the surplus of solar energy, generated from equipment, public spaces, offices, commercial and industrial fabric, to vulnerable population of the aforementioned superblocks.


The challenge will have to answer the following questions:

  • How much surplus of energy could be generated and from what type of buildings?

  • What type of consumers do we have on the grid based on their consumption curves?

  • How could the energy once generated be distributed to those who need it most?

  • To which extent the electricity bill of the vulnerable population could be reduced?

The finalist will receive a financial compensation of € 10,000 (excl. VAT) and will work closely with the technical teams of the Barcelona City Council, ACCIONA and the University of Barcelona. The experimentation phase will last approximately 3-4 months from the selection of the company.
