<br /> <br />...the SLCA must give <br />preference to certain <br />types of <br />customers <br />over others <br />wanting to <br />purchase <br />Federal <br />power. <br />Preference <br />customers <br />include <br />municipalities, <br />State and Federal <br />agencies, irrigation <br />districts, public utility <br />districts, Indian tribes, <br />and rural electric <br />cooperatives. <br /> <br /> <br />the electric power generated at SLCNIP hydropower facilities. Two <br />major factors influencing the extent of available resources are water <br />conditions and operational constraints of dams. Water conditions are <br />determined by the amount of water in reservoir storage and the inflow to <br />reservoirs from precipitation in the river basins above the reservoir. <br />Precipitation varies from year to year, producing fluctuations in reservoir <br />inflow and storage. A hydropower system that can carryover large <br />amounts of stored water from year to year can buffer some of this inflow <br />variability. Extended dry periods, however, lead to lower reservoir <br />storage levels and a reduction in power generating capability. Flexibility <br />in dam operations allows hydro facilities to respond quickly to electric <br />power demand. However, operations at several SLCNIP facilities either <br />have recently been restricted or are under consideration for restrictions. <br /> <br />Periodically, the SLCA evaluates updated hydrologic data and operating <br />criteria and uses the new information in establishing the power marketing <br />program. The power marketing program defines how much electrical <br />power and energy the SLCA has available for sale, along with the associ- <br />ated contract terms and conditions. <br /> <br /> <br />The current SLCNIP firm power commitments under the Post-1989 <br />Interim Marketing Program total 1,291 MW of capacity and 2,672 GWh <br />of energy during the Winter season and 1,269 MW of capacity and 3,028 <br />GWh of energy in the summer season. These interim numbers are the <br />result of a court order revising the original Post-1989 Power Marketing <br />Program totals of 1,407 MW of capacity and 3,106 GWh of energy <br />during the Winter season and 1,315 MW of capacity and 2,904 GWh in <br />the Summer season. The interim totals will remain in effect until the <br />issuance of the Record of Decision for the SLCNIP Electric Power Mar- <br />keting EIS. <br /> <br /> . <br /> . <br /> . . <br /> :1 <br /> . . <br /> . . . <br />. .. . . <br />1. . , <br /> . . <br />.1 .4\ . . . <br /> . . <br />W. . . , <br /> <br /> <br /> <br />. <br /> <br />fi <br />'-s; <br /> <br />. <br />. . <br /> <br />%' <br /> <br />. . <br />- . <br /> <br />, <br />. <br />. <br /> <br />. ... <br /> <br />F <br />" <br />;t <br /> <br />4' <br />g. <br /> <br /> <br />. <br />,,-. <br />. <br /> <br />. <br /> <br /> <br />.
