6 FAQs about [Senegal bess degradation]

How is Bess degradation determined?

Since BESS degradation is a consequence of how the battery cells are operated (e.g.; initial and final state-of-charge (SOC) values within each cycle), we propose the use of a technique capable of estimating an equivalent degradation factor regardless of their operation.

Does Senegal have a battery energy storage project?

The national electric utility of Senegal, Senelec, has signed a 20-year CCA with Infinity Power for a battery energy storage project.
