The inclusion of these four councils as TERSA shareholders will enable them to benefit from energy which is 100% renewable, as well as tailored advice and energy savings.

The estimated consumption to be covered by power supplied to public buildings in these four municipal council is 19.2 GWh, equivalent to the consumption of over 5,500 families. In addition, some 4,800 tonnes of CO₂ emissions will be avoided, equating to more than 26 million kilometres driven by a diesel car, or going to the moon 68 times.

Owned by Barcelona City Council and the Barcelona Metropolitan Area (AMB), Barcelona Energia is the biggest public power distributor in the Spanish state. The company started offeing its service to the general public in January 2019. In less than a year, since last June, the following municipal councils have joined: Castellbisbal, l’Hospitalet de Llobregat, Santa Coloma de Gramenet, el Prat de Llobregat, Sant Boi de Llobregat, Sant Feliu de Llobregat, Sant Just Desvern, Sant Vicenç dels Horts, Torrelles de Llobregat and Viladecans.

25,000 fewer tonnes of CO₂ in the atmosphere

The estimated consumption of these fourteen municipal councils is roughly 100 GWh (equivalent to that of nearly 30,000 families). In addition, the use of 100% renewable energy means these buildings will avoid emitting nearly 25,000 tonnes of CO₂ into the atmosphere (corresponding to nearly 3,430 laps around the equator in a diesel car).

If the 36 metropolitan councils joined up, the annual energy consumption would be an estimated 222,680,889 KWh. Overall, that would mean an estimated yearly saving of 55,670 tonnes of CO₂ (equivalent to what would be purified by 3,711,348 trees).

Barcelona Energia is among the ten largest power distributors in the metropolitan area, with over ten thousand supply points (between public supply points, individual users and companies).
