ACCIONA adds energy storage to solar

ACCIONA has made history by integrating a battery and smart control system into a photovoltaic (PV) plant, connected to the main electricity grid. Located in Navarre, Northern Spain, the ILIS Innovative Lithium-Ion System management design for MW-level solar plants (ILIS) project uses SAFT’s lithium-ion batteries with a capacity of 1.1MW and 560kWh of power.

Part of a growing trend for the integration of energy storage and solar power, ILIS has been designed to improve the integration of photovoltaic energy into the grid and bring about greater penetration of this technology in the electric power system, says ACCIONA. The €5.5m for the project, which began in 2010 and has been scheduled to run until April next year, comes from the Spanish taxpayer by way of the Ministry of Economy and Competitiveness and by the Government of Navarra.
