FAIRFIELD, Mont. (AP) — Construction of a 25-megawatt, 15-tower wind farm is expected to begin north of Fairfield following negotiations between the developer and NorthWestern Energy.

The Montana Public Service Commission had rejected a settlement agreement on the power purchase price between NorthWestern and WINData LLC, but reconsidered and approved a 25-year contract.

WINData CEO Martin Wilde says getting the power contract has been the biggest challenge to getting a second site.

According to the Great Falls Tribune ( ), developers say the second site has perfect wind conditions for more wind powered generators.
