CHICAGO, Ill., and AUSTIN, Texas (December 18, 2012) – Invenergy LLC, a Chicago-based leading clean energy generation company, and Xtreme Power, a world leader in real-time power management and energy storage solutions, today announced the launch of their joint venture to deploy a fast-acting energy storage system in Illinois.

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 vital for PJM’s grid reliability.

Xtreme Power’s 1.5 MW Regulation Power ManagementTM (RPM) is a versatile, scalable asset which will ultimately utilize long-life lithium-titanate battery technology and an AGC 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.

“With the wind industry developing innovative solutions for the future, we’re excited to lead the way by investing in cutting-edge storage technology for grid stability,” said Jim Shield, Chief Development Officer at Invenergy, North America’s largest independent wind power generation company. “As we continue to expand our clean energy portfolio, this battery system complements our Grand Ridge Wind facility. Invenergy is pleased to work with Xtreme Power on this project.”

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’s operational experience is unmatched in the energy storage industry, serving more than eleven customers and remotely monitoring over 120,000 hours of operations.

“We are thrilled to add Invenergy to our growing list of marquee customers in the electric utility industry, and proud to launch this joint fast-acting frequency regulation project,” said Alan Gotcher, Chief Executive Officer of Xtreme Power. “Furthermore, we’re excited to add new battery chemistry to our product offering, which, in this case, deploys lithium-titanate. The chemistry’s performance characteristics match perfectly with the needs of this new market.”
