DUKE POWER'S MARSHALL STATION: THREE UNITS IN TOP SIX /REPEATING TO CLEAR GARBLE/

 CHARLOTTE, N.C., Nov. 2 /PRNewswire/ -- Three of the four coal-fired units at Duke Power's (NYSE: DUK) Marshall Steam Station rank among the top six most efficient units in the nation, according to rankings released by Electric Light & Power -- an industry magazine.
 In its current issue, the magazine ranked Marshall Steam Station's Unit 4 as the nation's most efficient. Marshall Unit 3 ranked second, while Marshall Unit 2 ranked sixth. The station is located near Terrell, on the border of Catawba and Iredell counties.
 "This is obviously a proud moment for our employees," said Ronnie Campbell, manager of the 2,090-megawatt Marshall Steam Station. "Being ranked 1-2 in the nation is a reflection of the great team we have here. It's also good news for our customers, who benefit by Duke Power running such efficient units."
 The efficiency at coal-fired power plants is measured by how well the power plant converts heat -- which is produced by burning coal -- into electricity. The less heat used to produce each kilowatt-hour, the higher the efficiency ranking. The heat is measured in British thermal units, the electricity in kilowatt-hours. Btu per kilowatt-hour is called "heat rate."
 Marshall Unit 4's heat rate was 8,989 Btu per kwh, while Unit 3's heat rate was 9,037. Duke Power's eight coal-fired stations had an average heat rate of 9,428 Btu per kwh.
 Marshall Unit 1 would have been ranked in the top 20, but did not operate enough to be included in the competition.
 In 1992, Marshall Steam Station generated more than 10.2 billion kilowatt-hours of electricity. That amount could power 100,000 homes for almost nine years.
 Marshall Steam Station's first two units became operational in 1965 and 1966, while the second two units became operational in 1969 and 1970.
