Due to non-synchronous generation and the grow of electricity over fossils in energy mix, grid operators face an increasingly complex challenge in maintaining voltage and frequency stability - critical pillars of reliable power system operation. 

To support System Operators to overcome these challenges, Teraloop FESS (flywheel energy storage system) offers unique and reliable capability for the most demanding grid ancillary services. Combined with application-tailored power electronics the FESS provides a high-power response in less than 10 milliseconds and maintains power delivery for dozens of minutes. The ideal solution for delivering critical ancillary services such as fast frequency response, synthetic inertia, black start and voltage support.
