The Fekola Hybrid Power Station (French Centrale électrique hybride de Fekola) is a 115 MW (154,000 hp) power plant in Mali. The power system comprises 68 MW of thermal energy, 30 MW of solar power and 17.3 MW of lithium ion battery energy storage. The power station is owned by B2Gold Corporation, a Canadian mining company. Dornier Suntrace GmbH (also Suntr. CountryLocationFadougou, , Official nameCentrale électrique hybride de FekolaStatusOperationalLocationThe power station is located in the settlement of Fadougou, in , in the in southwestern Mali, near the border with . Fekola Gold Mine is located approximately 61 kilometres (38 mi), so. .
Before 2019, the Fekola gold mine had a legacy thermal power station with capacity of 68 megawatts. The thermal station has six units, with each unit capable of generating 11.33 MW at maximum output. These unit. .
The addition of the solar farm and the battery storage system allows the power station to rest three of the six thermal generators during the day. This allows the electricity demand of the gold mine during daytime to.

In 2010, Beacon Power began testing of their Smart Energy 25 (Gen 4) flywheel energy storage system at a wind farm in Tehachapi, California. The system was part of a wind power and flywheel demonstration project being carried out for the California Energy Commission.OverviewFlywheel energy storage (FES) works by spinning a rotor () and maintaining the energy in the system as . When energy is extracted from the system, the flywheel's rotational speed is reduced a. .
A typical system consists of a flywheel supported by connected to a . The flywheel and sometimes motor–generator may be enclosed in a to reduce fricti. .
Compared with other ways to store electricity, FES systems have long lifetimes (lasting decades with little or no maintenance; full-cycle lifetimes quoted for flywheels range from in excess of 10 , up to 10 , cycles.

Success of cadmium telluride PV has been due to the low cost achievable with the CdTe technology, made possible by combining adequate efficiency with lower module area costs. Direct manufacturing cost for CdTe PV modules reached $0.57 per watt in 2013, and capital cost per new watt of capacity was about $0.9 per watt (including land and buildings) in 2008.
