Portland General Electric Co was incorporated in 1930. The Company is a vertically integrated electric utility engaged in the generation, purchase, transmission, distribution, and retail sale of electricity in the state of Oregon. The Company operates as a cost-based, regulated electric utility. The Company's retail load requirement is met with both Company-owned generation and power purchased in the wholesale market. The Company also participates in the wholesale market by purchasing and selling electricity and natural gas in an effort to obtain reasonably-priced power for its retail customers. It has authority under its FERC Market-Based Rates tariff to charge market-based rates for wholesale energy sales. The Company offers transmission service pursuant to its Open Access Transmission Tariff (OATT), which is filed with the FERC. In addition to cost-of-service pricing, residential and small commercial customers can select portfolio options from the company that include time-of-use and renewable resource pricing. Transmission systems deliver energy from generating facilities to distribution systems for final delivery to customers. The transmission system is part of the Western Interconnection, the regional grid in the western United States. The Western Interconnection includes the interconnected transmission systems of 11 western states, two Canadian provinces and parts of Mexico, and is subject to the reliability rules of the WECC and the NERC. The Company is subject to regulation by several federal agencies, including the Federal Energy Regulatory Commission (FERC), the U.S. Department of Transportation's Pipeline and Hazardous Materials Safety Administration (PHMSA), and the Nuclear Regulatory Commission (NRC).
