Five powerplants haye been installed at three of the four CRSP storage units. The Flaming Gorge Unit's Powerplant came on line in November 1963, followed by the Glen Canyon Unit's Powerplant in September 1964. In the Aspinall Unit, the Blue Mesa Powerplant came on line in September 1967, the Morrow Point Powerplant in December 1970, and the Crystal Powerplant in September 1978. A powerplant has been installed on one of the twenty participating projects, and powerplants may be installed on other participating projects where such developments are found to be feasible and are authorized by Congress. The Fontenelle Powerplant of the Seedskadee participating project came on line in May 1968. CRSP transmission facilities consist of a high-voltage trans- mission grid to deliver power to certain delivery points, to provide interconnections among the CRSP powerplants, and to interconnect with other existing Federal and non-Federal transmission systems. B. Rio Grande Project. RGP was initially authorized as an irrigation project by the Act of February 25, 1905, ch. 798, 33 Stat. 814. Elephant Butte Dam was completed in 1916. The construction of Caballo Dam, a flood control and regulating structure located downstream from Elephant Butte, was completed in 1938. The Interior Department Appropriation Act, 1938, ch. 570, 50 Stat. 593, of August 9, 1937, provided for the application of power revenues toward repayment of the project. The Elephant Butte Powerplant was constructed between 1938 and 1940 and went on-line in January 1941. Except for the Elephant Butte Switchyard, no transmission facilities are associated with the Elephant Butte Powerplant. The project is operated as an irrigation water supply project, and power generation is secondary in priority. C. Collbran Project. The Act of July 3, 1952, ch. 565, 66 Stat. 325, authorized the Secretary of the Interior to construct, operate, and maintain Collbran for the purpose of supplying water for irrigation, producing hydropower and, incidental to irrigation and hydropower, for preservation of fish and wildlife. The project features include the Vega Dam and Reservoir, the Upper and Lower Molina Powerplants, and various diversion dams, waterways, pipelines, and penstocks. Transmission facilities connect the two powerplants with the Collbran Switchyard, which is owned by a non- Federal utility. Appendix B lists the projected Integrated Projects generating capabilities with planned uprating of the generators through replacing stator windings, rotor poles and windings, and by making other electrical and mechanical modifications as needed. IV. HISTORY OF POWER RATES The current Integrated Projects firm power rate has been in effect since October 1, 1987, when CRSP, RGP, and Collbran were integrated to establish a common rate. This rate consists of a capacity charge of 4
