Subsidiaries of Bonneville Pacific Corp., 257 E. 200 South, and Texaco Cogeneration and Power Co. have entered into two partnership agreements to design, construct and operate two 85-megawatt natural gas-fired co-generation facilities near Las Vegas.

A majority of the natural gas requirement will be supplied by Texaco Gas Marketing Inc., another subsidiary of Texaco Inc., under long-term gas management agreements with the partnerships, said Robert A. Keegan, BPC executive vice president, and James L. Pauley, TCAP president."This represents the fulfillment of over two years worth of development by Bonneville in these projects. These partnerships greatly increase the overall value of the projects by the unique structure of the fuel supply agreements," Keegan said.

The two projects, which will go on line in mid- to late 1992, will be similar in design and construction. Construction will begin on both projects in early 1991, with each facility costing $100 million.
