This is a revised Plano we did late yesterday. It was adjusted from Lowell, 
Mass Nepco estimate and we changed format to more closely match  Homestead 
form.

Biggest differences 'tween original Plano and original Homestead were:

Homestead had dual fuel     +4M
Homestead had additional piling and foundation bulks  +1.8M
Homestead was connecting to a complicated t-line config +1.5M
Homestead had an FPL substation    +5M
Homestead did not need as much gas pipeline    -2.1M
Homestead used 6% margin     +4.4M
Homestead had lower capacity due to additional chilling  +1.5% (not capital 
cost but does change $/kW)

Differences from original Plano to new Plano is that Nepco has estimated a 
union job for Lowell. This impacts indirects upward by about $5M and 
construction up above my earlier guesstimate by about $4M. I had doubled the 
cost per manhour which Nepco also did but additionally they added manhours 
for productivity loss. Additionally I moved new Plano margin to 6%.

New Homestead went up due to raw water pretreatment and first stage RO but we 
dropped the substation cost so total estimated cost went down by a coupla of 
million.

Numbers still just should be used for screening, no commitment. 

These summaries should not be passed around.
