Saft, a subsidiary of TotalEnergies, has won a major contract from Eiffage Energie Systèmes to deliver a 10 MW energy storage system (ESS) to help ensure smooth grid integration for the Boundiali solar photovoltaic power plant. The 37.5 MW plant, owned and operated by CI-Energies (Côte d’Ivoire Energies), will be the first large-scale solar project in Côte d'Ivoire, and in operation is expected to avoid the annual emission of 27 000 tonnes of CO2. It is scheduled for commissioning at the Boundiali site in September this year.
The primary role of the ESS will be capacity firming and smoothing of the solar plant’s intermittent output to ensure a predictable and reliable feed into the local grid. The fully-integrated lithium-ion ESS will comprise six Saft Intensium Max High Energy containers, providing a total of 13.8 MWh energy storage, together with power conversion and medium voltage power station systems.
Côte d'Ivoire had an installed electricity production capacity of 2229 MW in 2019 and is expected to double its production by 2030. Electricity at present is largely provided by thermal energy and hydroelectric dams.
CI Energies is also planning to test the ESS in other network support options such as ramp rate control, frequency support, reactive power support and black start. This will provide useful data on the aging of the battery in different service stacking scenarios.
