xStorage Home makes the city of Malaunay more sustainable

Discover how xStorage Home helps the city of Malaunay in Normandy, France, to optimise its collective solar self-consumption and reach the EU’s sustainability goals.

Malaunay, a leading sustainable city

Malaunay has quickly become a leading sustainable city, not only in France, but also at international level. Committed to reach the 3x20 objectives set by the European Union, Malaunay started its energy transition back in 2006. Malaunay is now the first city in France to further improve collective self-consumption by installing xStorage Home and PV panels on the roofs of public buildings.

Enabling a smooth energy transition

Thanks to an xStorage Home system, which is connected to 135 sqm of solar panels on a church roof, the city can now locally produce, store and reuse energy for self-consumption to cover the needs of the church building. With a back-up capacity of nine hours, the energy storage system can also take over to provide the church with lighting in the event of a power outage. The installation can also be used to power other public buildings.

A more energy-efficient city

Today, 70 % of the city's municipal buildings (nearly 19,000 m2) are powered by renewable energy. In addition to a lower environmental footprint, the city of Malaunay has also achieved cost savings on its energy bills. Based on the increase in energy prices since 2006, the city's energy bill this year would have amounted to €419,000. Instead, the actual figure was €204,000, which represents savings of over 50 %. Furthermore, the city has not had to raise taxes since 2004 and continues to reduce its debt. Since 2017, the city of Malaunay has been a member of the French National Association of Communities with Positive Energy (of which there are nearly 200), which focuses on implementing a new energy model in France.

When we decided to embark on this adventure of collective energy self-consumption, we were looking for a partner that would support us technologically, but above all a team that would be motivated and willing to invest with us in this unique project. Eaton’s innovative approach immediately won us over, and it was only natural that we chose the xStorage Home solution.
