EPS signs EPC contract with Endesa to build 20MW largest electric battery in Spain

Milan, 13 September 2017 – Electro Power Systems S.A. (“EPS”), technology pioneer in energy storage systems and microgrids, listed on the French-regulated market Euronext Paris (EPS:FP) announces the signing with Endesa of an EPC contract for the design, construction and commissioning of a 20MW utility-scale storage system.

EPS will deliver a unique turnkey solution for serving Endesa’s thermoelectric plant Carboneras located in Almeria, Spain. The storage system will be the largest in Spain and will be composed by 24 inverters, 16 containers of which 8 for PCS and 8 for Li-ion storage, with a total installed capacity of 20MW/11.7MWh.

The installation of this utility-scale system aims to make the plant more flexible and improve its response to the load fluctuations in the current electricity system resulting from the intermittency caused by an increased penetration of renewables. The addition of storage is also expected to reduce maintenance costs for the plant’s main components and extend their useful life.

The project is part of the general evolution of the Carboneras coal plant to better serve the current electricity system. A significant penetration of intermittent renewable energies, mainly wind power, are forcing the plant to adjust its production and implement backup functions to meet electricity demand at all times.

“This contract confirms that EPS belongs to a selected pool of global players, able to deliver on a turnkey basis utility-scale storage systems to the world’s leading energy companies” stated Giuseppe Artizzu, Executive Director – Strategy and Business Development of EPS.

Carlalberto Guglielminotti, CEO of EPS Group also stated: “Is an exceptional result for EPS and confirms the competitiveness of our cutting-edge technology”.
The project is expected to become operational by June 2018.
