The 9.72MW Two Dot plant will have six GE 1.62MW turbines and be located on 176 acres of rural agricultural land around 93 miles east of the state capital of Helena.
New Jersey Resources chairman and CEO Laurence M. Downes said that the acquisition of the Two Dot wind project is a significant milestone for NJR Clean Energy Ventures.
"As our first onshore wind project, it represents a viable long-term growth opportunity for our company and share-owners," Downes added.
"We believe it is a sound investment that advances the planned diversification of our clean energy portfolio."
NJR Clean Energy Ventures will invest around $22m and will also be responsible for constructing, owning and operating the wind farm.
Under a 25-year power purchase agreement (PPA), the output of the plant will be sold to NorthWestern Energy.
NJR Clean Energy Ventures will select Mortenson Construction for engineering, procurement and construction services for the Two Dot project.
The wind farm is expected to become operational summer 2014.
