energy transition
Over the years, the SDEF has become a major player in the energy transition of its territory. It is involved in several activities supporting energy efficiency and sustainability such as :
- The development of renewable energy infrastructures (55 photovoltaic plants by the end of 2021)
- Energy Saving Certificate pooling,
- Joint energy and electricity purchasing,
- The development of charging infrastructure for electric vehicles (a network of 215 stations),
- Smart grids.
