Phased construction of Gasification-Combined-Cycle power plants
- Fluor Daniel, Inc., Irvine, CA (USA)
As utility planners consider their options for adding power generation capacity, it is important to be aware of the technical status, economic benefit, and environmental impact of the candidate technologies. One power generation option that offers particular advantages for incremental capacity addition is the phased Gasification Combined Cycle (GCC). The inherent flexibility of the phased GCC approach accommodates changing fuel prices and availabilities and allows utilities to match load growth requirements as they arise. Phased GCC construction reduces financial and regulatory risk by providing a strategy for dealing with external variables -- including fuel prices, government regulation, and load demand -- and by allowing the deferral of capital expenditures until they are warranted by rising prices of premium fuels. These economic benefits parallel the environmental benefits that accrue from the ability of GCC plants to easily meet stringent emissions criteria. Further, adopting the phased GCC approach does not commit the utility to full implementation; should conditions make it undesirable to proceed, the process may be discontinued at any stage without penalizing plant performance. The purpose of this book is to provide an introduction to the comparative advantages, risks, and unique planning issues involved with passed GCC operation. It addresses the value of the phased GCC approach as a strategic planning option, its financial and economic benefits, and its suitability as a viable response to acid rain legislation. For utility executives, planners, and engineers, the book presents an overview of the technologies and key issues involved in applying the phasing concept. Attention is also given to equipment and site selection considerations. 51 refs., 11 tabs.
