The energy storage installation, located at Invenergy’s Grand Ridge Wind project site in La Salle County, will supply clean, renewable power to the new frequency response market administered by regional transmission organization PJM. Efficient frequency regulation is essential for PJM’s grid reliability.

Xtreme Power’s 1.5 MW Regulation Power Management (RPM) is a versatile, scalable asset which will ultimately utilize long-life lithium-titanate battery technology and an AGC (automatic generation control) signal to harness full four-quadrant power in less than one second. Such instantaneous energy delivery will enable Invenergy to help balance supply and demand in the PJM market.

This project marks Xtreme Power’s fourteenth installation and will add to the company’s ~77 MW project portfolio, when it begins operation in December. Xtreme Power serves more than eleven customers and remotely monitors more than 120,000 hours of operations.

Founded in November 2004, Xtreme Power designs, engineers, installs, and monitors integrated energy storage and power management systems for independent power producers, transmission and distribution utilities, and commercial & industrial end users, among others.

Xtreme Power is a privately held company and has raised in excess of $80 million since its founding. Current investors include SAIL Capital Partners, Bessemer Venture Partners, The Dow Chemical Company, BP and Fluor, among others.

Invenergy and its affiliated companies develop, own and operate large-scale renewable and other clean energy generation facilities in North America and Europe.
