Invenergy's Grand Ridge Energy Storage Project Named Finalist for Prestigious Industry Award

Illinois Project Short-Listed for Excellence by Energy Storage North America

CHICAGO, Aug. 18, 2015 -- Invenergy LLC ("Invenergy"), a leader in innovative energy storage solutions, announced today that its Grand Ridge Energy Storage project has been named a finalist by Energy Storage North America (ESNA) - North America's largest energy storage conference and exposition - for a highly-coveted 2015 Innovation Award. The citation is for excellence in installed energy storage in the Centralized Storage category for utility-scale projects, with finalists selected after a rigorous review of dozens of award applications.

With a 31.5 MW power rating, Grand Ridge Energy Storage is the second-largest lithium project in the world. Operational since May of this year, it utilizes BYD America's Containerized Energy Storage System. The unit is located in La Salle County, Illinois, at Invenergy's Grand Ridge Energy Center, the largest in the world featuring wind, solar, and advanced energy storage in one location. It is comprised of a 210 MW wind farm; a 20 MW solar project; and a second, 1.5 MW energy storage project.

"This recognition by ESNA speaks to Invenergy's commitment to providing innovative storage solutions for our customers," said Kris Zadlo, Senior Vice President of Regulatory Affairs, Storage, and Transmission at Invenergy. "We're very proud to have developed a leadership position in the energy storage industry, which we believe will play a transformative role in the evolution of the electric grid."

The annual ESNA awards are determined solely by Twitter voting, which is now underway and will conclude at 11:59 p.m. on Friday, October 2, 2015. Voting for the Grand Ridge Energy Project can be done via a tweet that must include the hashtag #ESNA2015Awards and at least one of these project-identifiers: #GrandRidge, #Invenergy, or #BYD. One tweet per user will count toward the final results.

Requiring just a single fastener (lag bolt or self-drilling), GreenFasten provides the fastest install in the industry and will not void roofing manufacturer's warranties. Backed by IAPMO certification, GreenFasten delivers a mounting solution for all new or existing (retrofit) composition shingle roofs, and is the most cost-effective solution available. Like all of the solar roof mount solutions in our line of products, GreenFasten is made in the USA using recycled materials.
