1. Base Module - scaled linearly from 500 MW Sargent & Lundy model unit (2009 dollars)

440.5 MW + 523.8 MW - 16,615.000 x MW/500

2. Installation Costs - 15% of Base Module

3. Owner Costs - 5% x (Base Module + Installation)

4. Cost of Lost Power Generation - 5 days @ .06/kwh x annual kwh/365

5. 2009-2013 Cost Adjustment - 14% increase of (Base Module+Owner Costs+Installation Costs)

6. Annualized Cost Recovery Factor n = 3 years =.38105 n = 5 years =.24389

i = 7%

7. Annual Fixed O&M(Labor, Maintenance, Admin) = .59 x kw - 440,500 kw and 523,800 kw

8. Reagent Costs = Trona Feed rate for 500MW at a 2 lb/MMBtu SO2 emission rate adjusted for size and SO2 of existing units (

 Cost of Trona ($220/Ton) x hours of operation 

6.33 x x x 220 x 6,223 = 15,264,630 

6.33 x x x 220 x 6,848 = 19,974,219 

9. Disposal Cost - (tons/hr of flyash and sorbent for 500MW adjusted for sorbent feed rate) x operating hours per year x disposa

[ (11.07 x x + 20.73 x ) ] x 6,223 x 50 = 8,034,344 

[ (11.07 x x + 20.73 x ) ] x 6,848 x 50 = 10,513,176
