BOISE, Idaho (AP) — Federal energy regulators have filed a lawsuit against the Idaho Public Utility Commission after the state agency voided contracts between two wind-energy producers and Idaho Power. The U.S. Federal Regulatory Commission says voiding the contracts violates the Public Utility Regulatory Policies Act, which is meant to level the playing field for upstart energy companies.

The Idaho State Journal reports ( the Idaho agency ruled the contracts were null because they were not signed prior to Dec. 14, 2010, when the qualification threshold for smaller energy providers was reduced from 10 megawatts to 100 kilowatts. Wasatch Wind Intermountain and Murphy Flat, had agreements in place with Idaho Power. The Idaho PUC has not yet responded to the suit, which was filed Feb. 22.
