Best data we have for a 7FA simple cycle is the East Coast Power Linden #7 that NEPCO did. EPC cost for single unit was $63,000,000 based on a $34,000,000 7FA cost. Scope was for 7FA with CO catalyst and stack, generator breaker, main power transformer, 4160 V switchgear, 480 switchgear, small control room, light oil tank and pumps for backup fuel, natural gas heater. Best data we have for 7FA combined cycle is Pittsburg.

I was able to get a better CCTG model run so performance is better than my wild guess Monday. EPC cost is roughly same basis, did do some adds and subtracts based on your memo. May not have captured everything but should be in the ball park. Numbers should be useful for conceptual screening proformas to see if we are in ballpark, we should do a tasking letter and a complete conceptual scope/performance/estimate if you need any numbers that we might base something we put on an offer table. Obviously not reviewed or approved by anybody. Ben I will rerun your data in same form for Paducah - should look better Thanx Bruce Tracee Bersani@ECT 02/08/2000 02:13 PM To: Bruce Golden/ENRON_DEVELOPMENT@ENRON_DEVELOPMENT cc: Greg Blair/ENRON_DEVELOPMENT@ENRON_DEVELOPMENT, Mike Coleman/ENRON_DEVELOPMENT@ENRON_DEVELOPMENT Subject: Request for 7FA estimate Bruce, Per my voicemail, I am requesting an estimate for 7FA capital costs and heat rate for a proposed expansion of an IPP acquisition. We will be putting together a model to come up with an all-in capital cost ($/kw) for a single cycle, and possibly combined cycle facility with 1-3 7FAs and 0-1 steam turbines. The maximum MW of the site would be approximately 500 MW, so we would like to consider the following configurations: 1, 2, or 3 gas turbines single cycle, for a total of 170, 340, or 510 MW. 2 gas turbines plus one steam turbine in combined cycle, for a total of 510 MW. Here are some specifics about the facility: located in Lakewood NJ (east PJM) primary fuel is natural gas, with a back up fuel of heavy fuel oil expansion on site of current 238 MW combined cylce facility (2 ABB GT 11N1, w/ ABB KT Steam turbine ) for option 1: peaking facility, 25% dispatch for option 2: baseload facility, 90% dispatch total capacity of pipe is 150 MMcf, and current project uses only 30 MMcf (e.g. sufficient gas pipeline) From my discussions with Ben Rogers, I understand that the numbers were approximately $34-36 MM/turbine and installed capital cost was $571/kwh for 27FAs in combined cycle, at a heat rate of 7300. Please let me know if this information is enough to get an estimate of the turbine costs, heat rate, VO&M, start-up costs, and fuel requirements. Please give me a call when you get this so we can pick a time to discuss the project further. Regards, Tracee
