Collaborative advanced gas turbine (CAGT); intercooled aeroderivative ...
CAGT is working with aircraft engine suppliers to commercialize the ICAD gas turbine for various distributed, municipal, intermediate load, cogeneration and repowering applications through an interest group, application studies, market development and organizing a launch order to reduce market entry uncertainty.
Primary target is the 100 MW+ICAD based on the BOEING 747 and 777 aircraft engines and for suppliers to fully pay for development. CAGT is also investigating small ICAD (<20 MW) to leverage DOE Small Turbine Program and address smaller distributed applications.
CAGT was organized in 1991 as part of California collaborative for repowering and ICAD was identified in $5 million Phase I study. The 12-member Phase II Steering Committee is chaired by the Sacramento Municipal Utility District (SMUD) and National Power, and has mostly European membership (e.g., EdF, ENEL).
ICAD represents a new intermediate load and flexible generation product class offering a significant source of competitive advantage for users in restructuring markets. The total ICAD market is forecasted at 4000-5000 MW per year. Simple cycle ICAD will have efficiencies as high as 48+% LHV, cold start times in the range of 5-10 minutes, capital costs 20-30% lower than large combined cycles, is potentially transportable (50% salvage value) and a bottoming cycle can be added later to improve efficiency (up to 55-60%.)
Analysis indicates that ICAD will be superior to current simple and combined-cycle systems for capacity factors in the 10-50%+ range. ICAD is the first simple cycle turbine to have efficiencies greater than steam units (typically <30-40% with 24-hour cold start planning horizons). ICAD could accelerate the early retirement of many steam units currently used for intermediate and peaking service in restructured markets. Rapid growth is expected for intermediate load in U.S. in conjunction with deregulation, power pools, wheeling and merchant energy service strategies. Feedwater preheating of large steam units represents a substantial repowering U.S. and European market, potentially as a IPP value-added strategy in purchase of utility steam units.
Launch Order: CAGT is targeting organizing a launch order of about 10-15 units and simulating market development in 1996-97 in a relationship with a supplier. Elrkraft Project for feedwater preheating of new coal unit in Denmark is likely to be the first. CAGT has two projects under development in U.S. and is pursuing several project development alliances for feedwater preheating repowering, municipal power and with gas pipeline and marketing companies to for more. A new mid-sized Turbine (50-150 MS) Initiative is being proposed by the Gas Turbine Association for the $750 million DOE ATS Program. This potential could provide an alternative source of development and demonstration funding. Similar discussions are being pursued with EEC in Europe on both ICAD and feedwater application.
Cost to join CAGT: Membership costs $50K per year. A rate of return is being sought from the manufacturer for the membership costs.
