The Alstom-Saft consortium is partnering with the EDF group to supply an initial energy storage system using a container of lithium-ion (Li-ion) batterie. Alstoms MaxSine eStorage solution, connected to Safts Intensium Max 20M storage system, will be installed on EDF R&Ds experimental concept grid, designed to develop grids and smart electrical systems. The installation is located south of Paris, the first of its kind in France.
According to Alstom, Frequency is an indicator of the grid stability; it represents the balance between energy produced and energy consumed. To maintain this balance (and therefore the frequency), the operator uses the energy available through the primary reserve, mainly ensured by thermal or nuclear power plant operators, by blocking part of their production capacity.
Battery storage systems provide producers and grid operators with more flexibility over the available energy supply.
Patrick Plas, Alstom Grid senior vice- president of smart grid and HVDC, says, The battery energy storage system is part of the Nouvelle France Industrielle project, a scheme launched by the French government in 2013. At the cutting edge of smart grid and power transportation infrastructure optimization technologies, Alstom Grid is contributing its technological expertise to the excellence of the French and European energy industry.
Safts director of the energy storage activity Franois Bouchon adds: Saft is delighted today to be providing the first battery for primary frequency control installed in France. With our international experience in the integration of renewable energies especially for networks in the Paris area, this innovative experiment will demonstrate the added value of a battery storage system and the performance of Li-ion technology in this promising sector.
Alstom and Saft previously collaborated on the Nice Grid demonstration project in late 2013, installing a 1 MW battery energy storage system to improve grid stability in the event of intermittent solar energy.
