Once the units are <br />shut down, the generators <br />can convert into their other <br />mode - acting as a 170,000- <br />horsepower electric motor <br />which drives the turbines in <br />the reverse direction and <br />pumps the same water back <br />up to the forebay. Water can <br />be pumped back into the <br />forebay during times when <br />power demands are low and <br />surplus low-rate power is <br />available from other <br />generating stations. Once <br />the water is returned to the <br />fore bay, it can be used <br />again to generate more <br />power during peak demand <br />times. <br /> <br />Public Service Company of <br />Colorado transmission <br />system at the Malta <br />Substation. This <br />interconnection with Puqlic <br />Service Company enables <br />Fryingpan-Arkansas <br />Project power 10 be <br />marketed to Colorado <br />customers. <br /> <br />The powerplant visitor <br />center, located on the upper <br />floor of the powerplanl. <br />provides overall information <br />regarding the Fryingpan- <br />Arkansas Project and <br />adjacent National Forest <br />lands. <br /> <br /> <br />16 <br /> <br />This pump-back storage <br />principal is advantageous <br />because the generating <br />units can be started Quickly, <br />and adjustments of power <br />output can be made rapidly <br />to respond to varying <br />patterns of daily and <br />seasonal power demands. <br /> <br />The power generation and <br />transmission system of the <br />project is connected to the <br />
