This means energy storage resources can more quickly release or absorb energy, compared to conventional generators (e.g. coal or natural gas - fired power plants) that historically have provided frequency regulation. (kleinmanenergy.upenn.edu)
In addition to the energy market batteries can be used for the ancillary services of frequency regulation and spinning reserves and the demonstration project participated in those markets. (pragmaticenvironmentalistofnewyork.blog)
Ultimately, a more streamlined frequency regulation system empowers a more reliable grid with the flexibility to support a changing energy generation mix. (kleinmanenergy.upenn.edu)
