Prairie Breeze is a 206.5 MW wind power plant located in Antelope County, Nebraska. The facility began operating in 2014 and is owned and operated by SunEdison LLC. It utilizes onshore wind turbine technology, with a single generator powered by GE Wind GE1.7-100 turbines. These turbines have a rotor diameter of 100 meters and a hub height of 80 meters.
The plant's primary fuel source is wind (WND). In its most recent year of operation, Prairie Breeze generated 595,657 MWh of electricity, achieving a capacity factor of 32.9%. The plant operates within the Southwest Power Pool (SPP) balancing authority and the Midwest Reliability Organization (MRO) NERC region. Prairie Breeze is ranked as the 9th largest wind farm out of 12 in Nebraska, and 247th out of 734 nationally.

No wholesale contracts disclosed in FERC EQR for this plant.
FERC EQR captures bilateral wholesale energy + capacity contracts ≥$1M/yr filed quarterly by jurisdictional sellers — covers renewable PPAs, thermal energy sales agreements, capacity contracts, and tolling agreements alike. Many plants don't appear: regulated-utility output flows to ratepayers via cost-of-service rather than bilateral contracts; small projects fall below the filing threshold; tax-equity-financed renewables route offtake to investors not utilities; merchant plants sell into ISO clearing markets without bilateral contracts. News-extracted buyer facts (below) may surface contracts disclosed only through announcements.
