6 Transmission facilities include a high-voltage transmission grid to deliver power to the established delivery points in the market area, to provide interconnections among the plants of the CRSP units and participating projects, and to interconnect with other existing Federal and utility systems within the market area. Additional transmission facilities are planned to deliver power from the additional generation mentioned above, to deliver to Northern Division customers the power to be withdrawn from the Southern Division, and to meet improved system reliability criteria. Map No. 594-400-79 is attached hereto as Figure 1 to show the CRSP powerplants and transmission facilities, as well as other principal power systems in the market area. . IV. HISTORY OF POWER RATES The first CRSP power rate, the R4-Fl schedule, was established on March 6, 1962. This rate was somewhat less than the prevailing power rates in the market area and was sufficient, based on the then current price level and the .then estimated future costs, to pay the project's annual operating costs and provide the repayments and irrigation assist- ance required. Following is that monthly rate schedule. Energy 3 mills per kWh Capacity $1.275 per kW, where the Kw is the greater of the maximum 30-minute integrated demand or the contract rate of delivery, such contract rate of delivery being established for the Summer Season (April through September) and/or for the Winter Season (October through March). Under the 1962 marketing criteria, sales to customers with no supplemental supply were permitted by contract provisions to receive their total energy requirements, regardless of load factor. Sales to customers with supplemental supply were permitted up to 70 percent seasonal load factor through March 1976. The average rate at 58.2 percent load factor was 6 mills per kWh, with the charge being divided equally between capacity and energy. Repayment studies made each year after 1962 indicated no adjust- ment was needed in the power rate until the fiscal year 1972 study was made. The latter study indicated that project revenues at the then existing rate would have resulted in repayment deficiencies within the allowable repayment periods of the various features which are to be repaid from power revenues. As a result of this situation, Reclamation initiated rate adjustment procedures which culminated in the Department of the Interior's November 1973 announced rate inc~ease. The new rate, the UC-Fl schedule, which became effective April 1, 1974, increased the monthly demand charge per kW from $1.275 to $1.32, based on the greater of the maximum monthly demand or seasonal contract rate of delivery as previously established, and leaving the energy charge at 3 mills per kWh. The UC-Fl rate at 58.2 percent load factor was 6.11 mills per kWh,
