output through a PPA for the first year (summer 01) and 50% of the output=

from 2002 through 2005. The following are the project specifics:

Enhanced Sprint and maximized output for summer conditions
? Needs substation and compressor=01,s (NNG is only 400 psi). - Substation=

estimate of $5.8M to $6.0 looks really high. I would usually assume single=

maybe $935,000 for a greenfield - maybe 775,000 on the way high side for th=

opportunity unless RPC needs some sort of major expansion and this really=

includes transmission lines, .....I will assume 115 kV on a transformer and=

we will add as Owners cost the $5.8M.

will do compression to 700 psig from 400 psig
? Peoples is the closest LDC
? No SCR Needed; Water-injection with water on-site - assume trailer demin,=

12 hours of storage
? Non-PSD
? Main fuel will be natural gas (100% of the time) with Fuel oil #2 as back=

- will have as dual fuel unit, assume no storage based on existing at site,=

will have forwarding pump

analysis so we can get good cost/1000 gal estimate

(capacity and heat rate - will generate new & clean with EPC margins along=

with expected heat rates for first 4 years based on 1500 hours operation pe=

Assume we want cost estimate - Nepco just did a single unit estimate and is=

going out with a proposal (cost is $26,000,000 starting from what they=20

we can sweet talk Redmond out of a copy). Probably should get a Nepco two d=

Any site data available? plot plans, substation one-lines, ....????
