Design of a 465 MW Combined Cycle Cogeneration Plant

In June 1983 Power Systems Engineering, Inc. began engineering of a base loaded 465 MW (net) combined cycle cogeneration plant (Figure 1) designed to sell up to 1,150,000 lb/hr (145.0 kg/s) of steam to a chemical plant in Houston, Texas, and sell up to 550,000 kW of electric power to the local electric utility (Houston Lighting & Power). Power Systems designed the plant, specified and procured equipment, arranged $220 million of project financing, will manage the construction of the plant, and will operate the plant. Power Systems negotiated the long-term steam contract with the chemical company and the power contract with HL&P. In addition, Power Systems obtained all permits and contracted for a long-term fuel supply.
