Energy Storage Becoming Part of the Energy Mix

FullSizeRender.jpgPerched 86 meters above the ground I survey the green energy mix before me; for miles around are wind turbines, in the distance a solar park, and below me sits a bank of inconspicuous containers which house the latest addition to Invenergy’s energy storage fleet.

I am at Invenergy’s Grand Ridge Energy Center, about 80 miles southwest of Chicago, which comprises of a 210 MW wind farm; a 20 MW solar project; and an existing 31.5 MW and 1.5 MW energy storage units.

The Grand Ridge Energy Storage Expansion provides fast-response regulation service to the PJM market. For the uninitiated PJM is a regional transmission organization (RTO) that coordinates the movement of wholesale electricity in all or parts of Delaware, Illinois, Indiana, Kentucky, Maryland, Michigan, New Jersey, North Carolina, Ohio, Pennsylvania, Tennessee, Virginia, West Virginia and the District of Columbia.

Energy storage has been on the rise in PJM territory since the independent system operator (ISO) revamped its wholesale electricity market in October 2012 to meet a new FERC mandate that ISOs/RTOs pay fast-responding frequency regulation sources, such as batteries, flywheels and demand response, based on their performance following the frequency regulation dispatch signal.

“We’ve seen great success from our storage facility at Grand Ridge thus far and this expansion is a reflection of our company’s commitment to the future of this revolutionary and transformative technology,” said Kris Zadlo, Senior Vice President of Regulatory Affairs, Storage and Transmission at Invenergy.

In 2015, Invenergy commissioned 63 MW of battery storage projects in the U.S. – more than any other developer, and with the addition of the Grand Ridge Energy Storage Expansion facility brings Invenergy’s total operating storage capacity to more than 68 MW.

“We’re going to grow the portfolio, the pipeline is big, it’s full, we’re starting to execute on those projects” said Chris Ozel, Manager of Energy Storage, “the market started off in regulation, it was a good way to get the industry going, but that is only one piece of it, going forward we’re going to see systems that are built around value stacks”.

These are certainly interesting times both for energy storage and Invenergy.
