  15. 15. Comparison Summary • Despite the variances in base plants, all the sites can be retrofitted with 90% PCC – No technical showstoppers with the available technology – Cogeneration lowers generating efficiency of Bayshore unit making it an unattractive capture option. (Not a reflection on CFB!) • The capital investment required can vary considerably: – Approximately $2000/kW difference in the PC sites studied • The LCOE after capture plant can vary considerably: – Approximately $37/MWhr difference in the sites studied • The CO2 avoided cost can vary between sites: – Approximately $30/ton difference in the sites studied • The more advanced solvents, currently in development , lower the efficiency penalty by ~2.5 percentage points © 2012 Electric Power Research Institute, Inc. All rights reserved. 15
  16. 16. What Features Make the Intermountain Site a Good Candidate for PCC Retrofit? • Good Baseline Efficiency - Net plant efficiency 35.6% HHV • Suitable IP/LP crossover pressure • Good turndown characteristics of the existing LP turbine • Age - Commissioned 1987, 24 yrs old (25yrs + of continued operation?) • • • • • • Size - 2x 950 MWe Gross (Good economies of scale) Existing AQCS - FGD system with potential for upgrade Lots of space available and in the right areas Favorable construction / labor costs Existing stack can be utilized Base loaded operation © 2012 Electric Power Research Institute, Inc.

  18. 18. Study Assumptions: Key economic assumptions included in this study: No contingency applied to PCC equipment 90% capacity factor applied Coal price: All capital costs have been adjusted to 2009 dollars PRB $1.80/MMBtu (HHV), $30/ton as-received. (17% price increase added for Bituminous & blend) For retrofits assumed paid off base plant Costs estimate were based on a +/- 30% accuracy from pre-front-end engineering and design studies 12.5 % annual capital carrying charge factor applied LCOE based on investor-owned utility revenue requirement analysis Captured CO2 is compressed to 2205 psig (152 barg) Optimized 30% wt. MEA system used on all cases (1380 Btu/lb-CO2 Heat of Regeneration) Constant value of $9.1/ton ($10/tonne) was applied to account for transport and storage. The TPC used, is defined as the sum of the following: Capital cost (broken into materials and installation including labor, subcontracts, field indirect costs, no sales tax assumed) / Engineering and other Home Office Overhead, including Fee / Warranty costs / Any Contingencies applied. © 2012 Electric Power Research Institute, Inc.
