, 000B78 . . The CRSP Transmission System as presently planned nears comple- tion. The 230-kv lines from Cheyenne to Glen Canyon and the two 345-kv lines from Glen Canyon to Phoenix are in operation. The Curecanti-poncha section of the Curecanti-Midway 230-kv line is com- pleted and excellent progress is being made on the Poncha-Midway sec- tion. The Rifle Substation, roads, and other final items remain. The Flagstaff Substation has been completed and only final checkout work remains. On February 7, major electrical systems of the Eastern and Western United States and Canada were interconnected for test pur- poses to form the largest power grid in the world. The test closure through the Bureau's Missouri River Basin Project transmission sys- tem linked virtually all major power systems of this country, plus major systems of Canada. The closure tied together some 265,000 miles of main transmission lines of 209 public and private power sys- tems with a generating capacity of nearly 245 million kilowatts, rep- resenting about 40 percent of the world's electrical power capacity. The intertie has been in service since February 7 and the operation is very encouraging. Barring unforeseen difficulties, the ties will remain closed. A close watch will be maintained throughout the sys- tems involved, and if major operational difficulties are encountered the points of intertie will be opened, technical difficulties corrected, and the ties re-established. Marketing of CRSP Power Our CRSP marketing situation continues to improve. We are not yet fully in the black since we are not quite able to make our full interest payments after meeting O&M costs. Our progress is satisfac- tory to meet project commitments during this build-up phase. By the end of 1966, 93 power systems had signed contracts fq~ the purchase of Storage Project firm power. These contracts providerfor the delivery of 959,000 kilowatts during the summer season and 712,000 kilowatts during the winter season. This is an increase of 50 percent in the power under contract compared with a year ago. Our estimates indicate that customers will require the full amount of power under contract by 1970 or 1971. Most of the 93 contracts are with the preference type customers which are guaranteed the delivery of the contract amounts for a period of 20 years. Five of the customers are nonpreference, such as the Bacific Power and Light Company, and these contracts are for shorter'terms, usually 5 years. At the end of these short terms the contracts may be extended if the available power is not required by preference customers. 3
