The trend is accelerating and energy companies are increasingly positioning themselves in the market for flexibility and energy storage solutions. “Storage is the key to facilitating the integration of renewable energies – photovoltaics in particular – and supporting the rise of new energy habits such as self-consumption and electric mobility”, asserts Gilles Rocchia, Director of Innovation and Marketing at Socomec. For the last five years, Benfeld, a company specialising in power cuts, control and conversion, has been developing an industrial solution for storing electrical power using lithium-ion batteries which store photovoltaic electricity. “We are currently working on various demonstrators to test our solutions on the ground. Working with Enedis in Nice, we are taking part in the Nice Smart Valley programme based on three trials: islanding, managing local flexibility and storage. Flexibility ensures a balance between supply and demand at local level. Islanding guarantees the electricity supply for a whole neighbourhood during an outage. And storage allows the electricity produced in the day to be used at night, for example.
