AVAILABILITY AND USE OF POWER FOR ALUMINUM COMPANIES Dr. FENTON. Is it not true that such tabulations will show that, particularly during the past year, both firm and interruptible aluminum loads were not being served, even though power was available to serve them? (The following information was supplied:) Yes, the tabulations show when the aluminum plants were not taking power at full-load capacity. At times power was not available to meet full demands for interruptible power. At other times power was available but the aluminum companies curtailed power consumption because of a depressed demand for their product. ESTIMATED AND ACTUAL POWER LOADS Dr. FENTON. I am interested in seeing how Bonneville's estimates of future loads compare with the actual record of loads. Please furnish for each month of the past 5 years, to date, a tabulation giving the peak load on the Bonneville system and give Bonneville's estimate of the annual peak in each year as reported to the FPC 2 years prior to such peak. (The matter referred to follows:) Comparison of estimated and actual BPA system peak loads firm only excludes deliveries to Northwest Power Pool Actual peak loads July.. August. September. October. November.. December. January. February. Estimates are based on normal weather conditions. Winter of 1957-58 temperatures were above normal. 2 The 1958-59 estimate prepared during February 1957 did not anticipate the business recession. In addition to reduced public agency loads, aluminum curtailment of firm power was 70,000 kw. 3 Estimate for annual Northwest Power Pool operating program. Dr. FENTON. Please furnish for the record for the past 5 years to date the monthly figures on the excess capacity that was available and energy that could have been generated at the Federal plants on the Bonneville system and which was not utilized or generated, as the case may be, because of lack of available load. If possible, indicate what portion of the energy loss would be classified as firm and what portion would be interruptible or dump. (The matter referred to follows:) Average capability theoretical surplus generation at Federal plants for Bonneville Power Administration, fiscal years 1954 through 1959 to date NOTE. The above data are the theoretical surplus energy available under actual streamflow conditions. In computing the theoretical generation, I unit at Grand Coulee was considered out of service for maintenance at all times. In addition, actual maintenance outages occurred which could have been shifted within the season had the generation been required to serve load. These outages are as follows: 1953-54. 1955-56 1956-57 Kilowatt-hours in thousands 169, 537 257, 535 467, 237 562, 616 1957-58. 831,000 Peak capability, theoretical surplus capacity at Federal plants for Bonneville Power Administration, fiscal years 1954 through 1958-59 to date NOTE. The above data are the theoretical surplus peak available under actual streamflow conditions.. In computing the theoretical generation, 1 unit at Grand Coulee was considered out of service for maintenance at all times. In addition, actual maintenance cutages occurred which could have been shifted within the season had the generation been required to serve load, therefore have not been considered in the above figures. ESTIMATED PEAK AND AVERAGE SURPLUS OF POWER Dr. FENTON. Based on present and expected load trends and presently scheduled Federal generating capacity, what maximum surplus energy and peak machine capability is to be expected on the BPA system for the next 5 years under median water conditions? Under adverse water conditions? 40731-59-pt. 249 (The matter referred to follows:) U.S. Columbia River power system estimated peak and average surplus adverse hydro (1936-37) Month Peak Average Peak Average Peak Average Peak energy Average 2,327 819 2,903 904 2,849 2,053 754 September. 3, 481 2, 313 1,092 97 806 3, 163 116 3, 151 0 October. 1,967 3,650 0 November.. 2, 399 0 0 2,397 December. 2, 642 2,066 January. 1,219 February 2,088 982 March. 996 April. 895 May. 1,645 0 June. 1,796 2, 166 2,508 2,934 3, 357 2,537 NOTE.-Surplus indicated is the difference between the total Federal generation after allowing for maintenance outages and the estimated firm, dump, and interruptible loads.

NUMBER AND COST OF PERSONNEL, 1958-60 Dr. FENTON. Regarding BPA personnel, I would like to have you insert data in the record, as you did last year, bringing up to date the tabulation which appears on pages 144-145 of the hearings of last year, giving 1958 actual, 1959 estimated, and 1960 estimate. (The matter referred to follows:) 1 U.S. Budget shows $15.154.400. Difference of $53,600 is personal services portion of $100,000 hourly wage ncrease supplemental. This supplemental was included in U.S. Budget for later transmission. Total personal services paid from funds available to Bonneville Power Administration, 1960 estimate, are distributed as follows: The administrative provisions of the appropriations act provide that not to exceed 12 percent of the appropriation for construction shall be available for construction work by force account or on a hired-labor basis. The estimated obligations in fiscal year 1960 for construction work by force account is $1,510,000, which includes all objects. The personal services component of this amount is estimated at $1,050,000. ENGINEERING COSTS Dr. FENTON. I would also like you to supply for the record the amount of contract engineering or other work performed during each of the past three fiscal years, of the type that had previously been performed by Bonneville personnel. (The matter referred to follows:) Engineering designed and survey work performed by contract which had previously been performed by Bonneville personnel is as follows: 1957. 1958. 1959. Fiscal year Dr. FENTON. Also furnish for the record the total cost of engineering, design, supervision, and administration of the construction program of BPA for each of the past 3 years. Include contract work cost requested above with proper note. (The matter referred to follows:) Engineering costs covering design, supervision, and administration are as follows: Fiscal year: 1957 1 Includes $313,700 for architect-engineer and survey contracts. 2 Includes $176,400 for architect-engineer and survey contracts. 3 Includes no architect-engineer and survey contracts. CONSTRUCTION PROJECT FEASIBILITY Amount 1 $2,206, 695 $2,297, 000 Dr. FENTON. In connection with the proposed construction by Bonneville of new facilities for serving existing customers, will the average annual incremental revenue over a 10-year period exceed the average annual fixed and operating costs of the new facilities? |
