 Increasing electrical energy requirements continued to place heavy demands
on suppliers of electric power in the State. Tampa Electric Company completed
its sixth generating unit of 425,000 kilowatts at the Francis J. Gannon station
at Port Sutton. The company has another coalfired station under development
at Big Bend with construction slated to begin in early 1968. The first 450,000-kilowatt
generating unit is scheduled to go into operation in 1970, the second in
1971. Florida Power Corp.'s Crystal River plant began producing electric
energy from 
generating unit No. 1 with a capacity of 421,000 kilowatts; the unit will
consume approximately 850,000 tons of coal per year. Construction also began
on unit No. 2 which will have a capacity of 510,000 kilowatts and which will
also be coal-fired. The company made application to the Atomic Energy Commission
to construct two nuclear powerplants in Citrus County. The facilities, designated
Crystal River Units 3 and 4 Nuclear Generating Stations, would use two pressurized
water reactors; each unit would have an initial gross capacity of 885,000
kilowatts, The
