Natural gas repowering creates new capacity and efficiency options for utilities
Repowering of aging electrical generation units in the U.S. is becoming increasingly accepted as a key technology for meeting future electrical demands. Repowering of steam electric generating capacity can be broadly defined as the replacement of existing equipment with new, more efficient systems that also offer lower emissions and substantially increased capacity. The feasibility of repowering units has been largely established. The basic equipment needed for gas-based repowering, including state-of-the-art gas turbines and heat recovery steam generators, are considered established and mature technologies by the utility industry. Nevertheless, important questions exist about the future of the repowering market. GRI had addressed these issues through three different projects in the last year: A technology-based, bottom-up study of repowering issues and markets; A top-down, capacity growth/demographic study of repowering markets; and A workshop with gas equipment and electric utility representative to discuss the future of gas repowering. These studies are summarized.
