With the Tennessee Valley Authority aiming to up the nuclear manufacturing of electricity, the utility's top executives are prepared to explain a plot to restrain some coal-fired operations.

TVA Chief Executive Officer Tom Kilgore and other top managers of the 77-year-old utility arranged a telephone news conference on Tuesday in order to talk about tactics to halt 1,000 megawatts of coal-fired power generation.

TVA executives are not ready to reveal prior to the conference call how it may possibly have an effect on staff.

The meeting corresponds with TVA using up $2.5 billion over a period of five years to complete a 1,200-megawatt reactor at its Watts Bar location by October 2012.

TVA provides power to almost 9 million consumers in Alabama, Tennessee, Georgia, North Carolina, Mississippi, Kentucky and Virginia. It manufactures about 8 percent from hydroelectric, about 32 percent from nuclear, and about 60 percent of its power from coal.
