Two Power Plants in the Works
Trigen Energy began construction of a $13.5 million, 15 MWcombined heat and power plant to provide 95% of the steam needs ofTrigen’s 135 St. Louis steam system customers. The plant consistsof two 5.2 MW solar turbines and 4.6 MW of back pressure steamturbines from Trigen Ewing.
Trigen will sell power into the wholesale market. The plant willgrow revenue by about $2.8 million per year from initial powersales and will cut fuel use for steam production and fixedoperating costs. The project will also enable construction of afurther 20 MW of peaking power using the steam in condensingturbines. When the plant goes on line in the second quarter of1999, it will generate nearly 40% of the district energy system’ssteam requirements with waste heat from the gas turbines.
And Alabama Power Co. began expansion of its James M. Barrygenerating plant near Mobile, AL. New gas-fired generating unitswill be capable of producing 800,000 kilowatts of electricity. Theunits will go on line in 2001. Alabama Power, a Southern Companysubsidiary, is an investor-owned utility serving more than 1.2million customers in the southern two-thirds of Alabama.
