Show Planf To Feed Power Artery What will happen to the energy that Huntington Canyon Can-yon Plant's giant, first unit generator will whirl out beginning be-ginning in 197-4? It will be delivered to Utah Tower & Light Co. load centers over the utility's util-ity's largest power artery, now under construction. This ixnver artery a 3-15,(XX) volt transmission line will stretch from a major system junction point near Salt Lake City to the Four Corners Corn-ers area in New Mexico and pass through the Huntington Hunting-ton Canyon Plant switchyard. switch-yard. This 370-mile transmission transmis-sion line will be the highest voltage power line in Utah and will be capable of delivering de-livering enough electricity to supply the needs of a city of some 500,000 people. POWER EXCHANGE In addition to delivering power from Huntington Canyon Can-yon riant into the Ur&L grid, this transmission lino will also increase service reliability re-liability and provide power exchange with adjacent systems sys-tems to the south. At Huntington Canyon riant, like other generating plants on Ur&L's modern system, electricity comes from the generator at relatively rela-tively low voltage pressure. Before it enters the longdistance long-distance transmission artery, voltage is raised by transformers trans-formers to 3-15,000 volts for transmission to load centers cen-ters in distant parts of the company's service area. At the other end of the transmission lines, power goes through another transformer trans-former where it is reduced to voltages suitable for industrial in-dustrial and commercial uses. The final change in voltage occurs in the residence resi-dence transformer near your home, where the voltage is reduced to 120 and 210 volts for use in your home. POOLS FACILITIES Utah Tower & Light has been a pioneer in interconnecting intercon-necting and pooling its facilities fa-cilities with neighboring utilities. util-ities. In 1927, it built a 138,000 volt line to connect with Idaho Tower Company. Today UT&L high voltage arteries connect with four large power pools, embracing embrac-ing major electric systems in the 11 western states, having a total capacity of over 50 million kilowatts. This region re-gion is interconnected to electric systems in eastern United States. This pooling arrangement makes it possible to install larger, more efficient generating gene-rating units than individual companies might otherwise justify, since part of the output out-put can bo available to other systems. Thus, large amounts of power can be exchanged between the companies to provide the most economical power generation over an entire en-tire area.

In order to operate its generating plants, transmission transmis-sion system and interconnections intercon-nections with the greatest possible efficiency, UT&L has in operation a communication communi-cation system that feeds in formation to computers with ability to make 100,000 calculations cal-culations in one second. This computer center makes it possible for its system to respond instantaneously and economically to load changes, selecting the most economical source of power, and, all the while, maintaining maintain-ing reliable customer service. |
