Envision Energy has energised Morocco’s first large-scale Battery Energy Storage System (BESS) at OCP Green Energy’s Benguerir mining site. The project features a 25 MW/125 MWh lithium iron phosphate battery system capable of storing electricity for up to five hours. The system has been energised and is now undergoing testing before entering commercial operation.
The BESS has been supplied and commissioned by Envision Energy under a contract signed with OCP Green Energy in late 2025. The system is connected to the existing solar power plant at the Benguerir mining site and is designed to store solar electricity generated during the daytime for use when industrial electricity demand is higher.
The project will help OCP Green Energy improve the utilisation of renewable power across its industrial operations. By shifting solar electricity from periods of high generation to peak-demand hours, the battery system is expected to improve energy flexibility and strengthen the continuity of renewable electricity supply.
Once fully operational, the 25 MW/125 MWh BESS is expected to reduce the OCP industrial site’s electricity bill during peak hours by around 25%. The system will operate with daily charging and discharging cycles and has an estimated operational lifetime of 25 years. It can also support functions such as frequency regulation and reactive power compensation.
The project represents an investment of nearly MAD 170 million and has received USD 20 million in financing from the Clean Technology Fund, managed through the African Development Bank Group. OCP Green Energy said the project also involved Moroccan expertise for system integration, engineering and related civil and electrical works.
The Benguerir BESS follows OCP Green Energy’s first phase of solar development, which includes 202 MWp of photovoltaic capacity across Benguerir, Foum Tizi and Oulad Farès. The battery project adds energy-storage capability to this renewable-energy infrastructure, allowing solar power to be stored and supplied according to industrial demand. OCP is also working with Mohammed VI Polytechnic University on LFP material development as part of its broader efforts to build a battery ecosystem in Morocco.
