French renewables power grid pilot shows limits of batteries in Europe

Source: Planetark, Date: June , 2015

A major pilot project by Europe's largest power network operator to integrate power from rooftop solar panels into the grid has shown that battery storage of renewable energy is not yet economically viable in Europe.The conclusion is a sobering one for proponents of sun and wind energy because as more of it comes on tap, better storage will be needed to keep the power produced when it is sunny and windy so it can be used at other times.The 30 million euro "Nice Grid" pilot is one of the biggest in a European Union-backed "Grid4EU" scheme in which France's EDF, Italy's Enel, Spain's Iberdrola Czech Republic's CEZ, Sweden's Vattenfall and Germany's RWE are testing the power grids of tomorrow. In the Mediterranean village of Carros on the outskirts of Nice, EDF's power grid unit ERDF has connected compact batteries to solar panels on rooftops and utility-size batteries to its local power distribution network. The technology works perfectly but the pilot has shown it is still too expensive for wider rollout."The economic model of the batteries is not mature yet," Philippe Monloubou, chief executive of French grid operator ERDF utility told Reuters.
