TOPEKA, Kan. (AP) - Washburn University in Topeka says it is committed to providing most of its energy from a Westar wind farm in the future.

Washburn and Westar Energy announced Monday they have signed a 20-year agreement for energy produced by a new wind farm planned in Nemaha County.

Under the agreement, the university will buy 4 megawatts of energy from the 300-megawatt wind farm to be developed by an affiliate of NextEra Energy Resources. The university said in a news release that would provide about 80 percent of the energy needs for Washburn and the Washburn Tech campuses. The new wind farm is expected to provide energy by the fourth quarter of 2020.

Washburn president Jerry Farley says the agreement will save the university up to $100,000 a year.
