Owners of Mohave Coal Plant Plan to Pull Out
LCG, June 21, 2006--Southern California Edison (SCE), the plant operator of the closed Mohave Generating Station near Laughlin, Nevada, has notified the other plant owners that it will no longer participate in activities to return the coal-fired plant to service. SCE closed the 1,580-MW plant at the end of last year, when the 35-year operating permit expired.
The facility is owned by SCE, the Salt River Project, Nevada Power Company, and the Los Angeles Department of Water and Power (LADWP), and their respective ownership percentages are: 56, 20, 14 and 10 percent. With SCE's announcement, LADWP stated that its focus is to decrease its investment in coal power and that it will withdraw from the plant.
Nevada Power Company, a wholly owned subsidiary of Sierra Pacific Resources, stated that it is not economically feasible to continue with the plant and that it would terminate its participation in the project.
A Salt River Project spokesperson stated that, "We're not going to go it alone. If we are going to participate in the future, we would have to have new owners."
The plant receives coal via a 270-mile coal slurry line originating at the Black Mesa Coal Mine, operated by Peabody Energy Corp. In order to reopen the plant, investments expected to cost $1.1 billion are necessary for a variety of improvements, including the installation of pollution control equipment required under a 1999 consent decree. Other issues include obtaining water supplies from the Hopi and Navajo tribes.
