Abstract
IPP's share in the world power generating market has grown year by year and its capacity had risen to 138, 909MW by July 1997. Major factors are deregulation of generating market in developed countries such as the U. K. and the active introduction of foreign IPPs to resolve the lack of electric power in developing countries. Many of IPPs expect that IPP's capacity will continue to grow because energy demand will continue to grow, rapidly in developing countries and modestly in mature markets.
