The World Bank has awarded Mercados – Aries International the Contract for the Owner´s Engineering services during the Construction of a Solar PV with BESS and the transmission line in Gambia. The plant is expected to have at least a 20MW output capacity and the BESS minimum size of 6MWh. Due to the weaknesses of existing power system in The Gambia, the implementation of Solar PV requires a careful implementation and the support of BESS. The plant is expected to mitigate the electricity supply constraints in the Country, while increasing the reliability of the power grid thanks to BESS.
