Teco Plans Power Plant Fueled by Gas from Petroleum Coke

LCG, Nov. 17, 2000--Teco Power Services Corp., an affiliate of Tampa Electric Co., said yesterday it plans to build an 850 megawatt power plant in Lake Charles, La. The facility will be built next door to a Citgo Petroleum Corp. refinery and be fueled by gas produced from petroleum coke.

Under a memorandum of understanding between Teco and Citgo, the oil company will supply the power plant with petroleum coke, a byproduct of the oil refining process. Teco will convert the coke to gas using a gasification process developed by Texaco Development Corp. The power plant will also burn excess refinery fuel gas.

The power plant will use 180 megawatts of its own power to operate the gasification process and sell the remaining 670 megawatts into the regional wholesale power market, the company said. Steam from the power plant will be used by Citgo to generate electricity in its own plant for refinery use.

As part of the deal, Texaco has the right to take a 50 percent ownership in the project. Citgo is a subsidiary of government owned oil monopoly Petroleos de Venezuela.
