Greensmith Energy installs upgraded software at AEP energy storage site

Greensmith Energy on April 4 announced the installation of the fifth generation of its GEMS grid-scale energy storage software at an American Electric Power Co. Inc. energy storage site.

Installation of Greensmith's software will allow the site to offer new services including qualifying for the frequency regulation market of of PJM Interconnection. The software has allowed AEP's sodium sulphur battery system at the 2 MW/14 MWh West Virginia facility to compete with lithium-ion battery systems and "easily pass" PJM's qualifications test, according to a news release.

"[T]he GEMS platform has been deployed with over 200 MW of energy storage systems using batteries from more than 16 battery manufacturers and 14 power conditioning system vendors," Greensmith Energy President and CEO John Jung said.

AEP made a $5 million strategic investment in Greensmith in September 2015.
