NextEra Energy Resources’ Rush Springs Energy Storage Facility might not look like much.
Nine structures that appear to be air-conditioned storage pods sit on the grid interconnection site for the Rush Springs Wind Farm in Grady County.
But inside of those pods? If you looked, you would see thousands of batteries like one that powers your laptop.
Those batteries give NextEra’s wind farm the ability to keep generating a limited amount of energy for a short period of time that can be used on the Southwest Power Pool (SPP) grid, even when Oklahoma’s winds are calm.
Admittedly, the facility’s ability to generate 10 megawatts of energy over a two-hour period seems rather meager up against the company’s neighboring wind farm, whose 100-plus turbines are capable of putting 250 megawatts of energy onto the grid when it is operating at full capacity.
But the project, introduced by the power provider as a way to test the technology, takes both NextEra and SPP a step toward a future where hundreds of facilities like it, only bigger, will help to power the grid.
The addition of battery storage to wind and solar facilities, officials said, changes the profile of those facilities …
