The Top of the World Windpower Project is a 200 megawatt wind farm located near Casper, Wyoming, USA. The project, operated by Duke Energy, was constructed on approximately 17,000 acres (6,900 ha) of land held under long-term lease in Converse County. The Top of the World Windpower Project began operation in 2010.
Read more on WikipediaThe Top of the World Windpower Project is a 200 MW wind farm located in Converse County, Wyoming. The plant, which began operating in 2010, utilizes a single generator and onshore wind turbine technology. The primary fuel source is wind (WND). Duke Energy is the parent company, with Duke Energy Renewables Services acting as the operator. The wind farm is connected to the PacifiCorp - East balancing authority within the Western Electricity Coordinating Council (WECC) NERC region.
The facility's wind turbines have a hub height of 80 meters and a rotor diameter of 77 meters. The turbines were manufactured by GE Wind, model GE1.5-77. In the most recent year of data, the plant generated 495,841 MWh, achieving a capacity factor of 28.3%. The Top of the World Windpower Project ranks as the 12th largest wind farm in Wyoming out of 24, and 339th nationally out of 734 wind farms.

This plant's balancing authority participates in CAISO's Western Energy Imbalance Market (WEIM). Direct nodal pricing data is not yet available.
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.
