Batteries hold promise for Wyoming wind power

A $44 million large-scale battery system proposed for a wind farm in Texas could be a “game-changer” for wind energy, an industry spokesman says.
Yet others in the wind power industry and the natural gas power industry, which provides a lot of fill-in power for wind energy, aren’t quite as excited.
The 36-gigawatt battery system — the largest known system tied to a wind farm — is slated for installation at the Duke Energy Corp.-owned 153-megawatt Notrees wind project.

Such a system can store energy produced during times of lower electricity consumption and then pump that energy into the grid during peak demand times — smoothing out the flow of electricity into the grid.

That might prove to be an important innovation for Wyoming, where several companies, including North Carolina-based Duke, are operating and developing wind farms to harness the state’s unceasingly world-class winds.
