The Frontier Windpower LLC unit of Duke Energy (NYSE: DUK) on Oct. 3 asked the Federal Energy Regulatory Commission to accept for filing its market-based rate tariff, under which Frontier will sell energy, capacity, and ancillary services at market-based rates.
Frontier had previously submitted to FERC a notice of self-certification as an Exempt Wholesale Generator, and that status as an EWG became effective on April 4, 2016.
Frontier has a 200-MW (nominal) wind farm located in Kay County, Oklahoma, which will be interconnected to the transmission system of Oklahoma Gas & Electric in the Southwest Power Pool region. The facility will consist of an array of fifty-six Vestas V126 3.3-MW wind turbine generators and five Vestas V126 3-MW wind turbines.
Frontier has entered into a long-term power purchase agreement (PPA) with the City Utilities of Springfield, Missouri, that provides for Springfield to purchase the full output for a term of 22 years beginning with commercial operations. Prior to the commercial operations date under the PPA, which is projected to be in late December of this year, Frontier will sell test energy to Springfield.
Frontier is a direct, wholly-owned subsidiary of Duke Energy Renewables Holding Co. LLC. An affiliate, Caprock Solar 1 LLC, is developing a 25-MW solar facility in the SPP region that is expected to begin commercial operations in early November 2016, Frontier noted.
