CASPER, Wyo. (AP) — A proposal to create a wind farm in eastern Wyoming could be stalled by further court battles from a group of landowners that has been fighting the project since 2011.

The Wyoming Industrial Siting Council approved the 46-turbine project last week, ruling that the park's new developer, sPower, has demonstrated that it has the financial capacity to build it.

The Northern Laramie Range Alliance disagrees and says it will likely appeal the ruling in court.

The 900-member group has waged a lengthy legal campaign against the proposed 80 megawatt wind farm. They lost cases in the Wyoming Supreme Court, the Federal Energy Regulatory Commission and federal court.

Naomi Keller, an sPower spokeswoman, says the company plans to begin construction before Feb. 15.
