Greensmith, AEP to install 4 MW storage system at Virginia hydro plants

Save It Saved

Greensmith Energy, a division of Wartsila, and American Electric Power have agreed to install a 4 MW energy storage system integrated with the Buck and Byllesby hydroelectric power plants in southwest Virginia. The integration of energy storage and software with hydroelectric generation is seen to be a world’s first hybridized system of its kind to provide ancillary services.

The system, due to begin operating in the first quarter of 2018, will deliver PJM one of the first new energy storage systems since the adoption of new frequency regulation signals and requirements for regulation service. The project will serve both of PJM’s frequency regulation markets.

“The advent and growth of hybridized power, enabled by the integration of intelligent energy storage, has always been a key part of our technology vision,” said Greensmith CEO John Jung. “Although we’ve delivered six grid-scale energy storage systems to the PJM market, this innovative hybrid project will see AEP raise the standard for hydroelectric use-cases globally. And the potential for hybridization is massive as hydroelectricity represents over 1,000 gigawatts of generation globally, roughly a sixth of the world’s total.”
