Invenergy has started commercial operation of a 31.5 MW energy storage project in Illinois, USA.
The Grand Ridge energy storage plant is based on lithium-ion iron phosphate battery technology and will provide fast-response regulation services to the PJM market.
It is located southwest of Chicago, at Invenergy’s Grand Ridge Energy Centre, home to a 210 MW wind farm, a 20 MW solar project and another 1.5 MW energy storage unit.
"Invenergy believes that energy storage holds the potential to be a transformative force in the evolution of the electric grid," said Kris Zadlo, Vice President of Regulatory Affairs and Transmission at Invenergy, which has over 100 MW of energy storage capacity in operation, construction or development in the USA.
Later this year the company will commission the 31.5 MW Beech Ridge energy storage project in West Virginia.
