27 October 2004 – Cinergy/PSI, General Electric Company and Bechtel Corporation have signed a letter of intent to study the feasibility of constructing a commercial, integrated gasification combined cycle (IGCC) generating station. This is the first plant of its kind announced under the recently proposed GE-Bechtel alliance.
PSI Energy, the Indiana operating company of Cinergy Corp., would own and operate the facility. Cinergy/PSI is considering several sites, including the site of its coal-fired station in Edwardsport, Ind. The plant would produce 500 to 600 MW of electricity to help meet increased electrical demand over the next decade. The letter of intent is the first step toward reaching a contract to design and construct the plant. Earlier this month GE and Bechtel announced their intent to develop a standard commercial offering for integrated gasification combined cycle projects in the United States.
Integrated gasification combined cycle plants turn coal to gas, removing most of the sulphur dioxide and other emissions before the gas is used to fuel a combustion turbine generator. The hot exhaust gases are then used to heat steam, driving a steam turbine generator. The technology uses less water and has fewer emissions than a conventional coal-fired plant with currently required pollution control equipment. Another benefit is the potential to remove mercury and carbon dioxide upstream of the combustion process at a lower cost than conventional plants.
“We face the need for additional generation in Indiana,” said James E. Rogers, chairman and chief executive of Cinergy Corp. “Given the high price of oil and the limited supplies of natural gas available, coal is the most practical alternative. Our challenge is to find ways to use an abundant resource in an economic and environmentally clean way. Coal gasification has proven to be efficient, and there is no cleaner coal technology.”
Several months of study lie ahead before a decision will be made whether to proceed with the project and at which location. The study is expected to be completed in 90 to 120 days and will result in site-specific data for assessing the economic feasibility of the project, plant performance and output, emissions, and the plant footprint. The companies also will work together during this period to develop public and government support for the project and a preliminary project execution plan.
“We are very pleased to be participating in the beginning stages of this important project,” said John Rice, president and chief executive officer for GE Energy, a division of General Electric Company. “The Cinergy proposal is clear evidence of the growing interest in this technology among utilities and power developers across the U.S. power sector today.”
Scott Ogilvie, president of Bechtel Power Corporation, added: “We look forward to working with GE and Cinergy to make this IGCC project a reality for reliable, affordable, clean electricity. The current environmental benefits of this technology, coupled with the potential to meet future environmental regulations at a lower cost to the customer, can lead to the successful commercialization of an advantaged clean coal power plant for Cinergy.”
GE Energy is a leading supplier of gas turbines for IGCC applications, having provided gas turbines for more than 60 percent of the world’s operating gas combined cycle plants. The company recently purchased the ChevronTexaco gasification business, whose technology has been applied to many of the world’s gasification combined cycle plants.
Bechtel Corporation is one of the world’s leading engineering, procurement and construction companies, with significant experience in the design and construction of all forms of power generation, including integrated gasification combined cycle plants. GE Energy has worked with Bechtel on a number of IGCC projects, including the 100 MW Cool Water plant in California, a demonstration project completed in 1984, and the Tampa Electric Company’s 250 MW Polk Power Station in Florida, which began operation in 1996.
Cinergy Corp. has a balanced, integrated portfolio consisting of two core businesses: regulated operations and commercial businesses. Cinergy’s regulated public utilities in Ohio, Indiana, and Kentucky serve 1.5 million electric customers and about 500 000 gas customers. In addition, its Indiana regulated company owns 7000 MW of generation. Cinergy’s competitive commercial businesses have 6300 MW of generating capacity with a profitable balance of stable existing customer portfolios, new customer origination, marketing and trading, and industrial-site cogeneration. Cinergy’s integrated businesses make it a Midwest leader in providing both low-cost generation and reliable electric and gas service.
