  2. UNECE Convention on Long-range Transboundary Air Pollution • General cost methodology • Calculation of boiler outlet emission loads • Economic assessment of DeNOx technologies • Economic assessment of dedusting technologies • Economic assessment of DeSOx technologies Agenda

  3. UNECE Convention on Long-range Transboundary Air Pollution • Draft BREF document should be available by the end of June • NEC Directive proposal should be available at the beginning of Autonm 2013 General information

  4. UNECE Convention on Long-range Transboundary Air Pollution Targets : reduction of the gap between the Baseline / MTFR for PM2.5 effects of 75 % Other pollutant not yet known, but optimised scenario A5 from IIASA could be the target Ceiling in 2025 or in 2030 NEC Directive in preparation

UNECE Convention on Long-range Transboundary Air Pollution Total annualcost General Cost MethodologyIntroduction Annualisationofinvestment Compositionof OPEX Fixed operatingcost Variable operatingcost P = interest rate | n = equipment lifetime | unit = equipment, reagent and electricity consumption, disposal, etc. General Cost Methodology

  7. UNECE Convention on Long-range Transboundary Air Pollution • Pollution control equipment expenditure • Equipment costs, • Primary pollution control device, • Auxiliary equipment, • Instrumention, • Any associated freight of equipment, • Modification to other equipment • Installation expenditure • project definition, design, and planning • purchase of land • general site preparation • buildings and civil works (including foundations/supports, erection, electrical, piping, • insulation, painting, etc.) • engineering, construction and field expenses • contractor selection costs and contractor fees • performance testing • start-up costs • cost of working capital Investment decompositionIn an ideal case, costs should include (BREF Economic and cross media effects Contingency allowance: In estimates of investment expenditure, a sum of money, or ‘contingency allowance’ included to cover expenses that cannot be estimated precisely. These are things that are known will happen but cannot be defined in such detail that they can be valued and added into the estimate. General Cost Methodology

  8. UNECE Convention on Long-range Transboundary Air Pollution When literature data are available, such a level of details on what is included or not is rarely provided Comparison of costs is difficult as it is difficult to know what is included or not Questionnaires : total costs have been provided but we do not know exactly what is included (no anwsers to the questions on costs items included. Investment decompositionIn an ideal case, costs should include (BREF Economic and cross media effects) General Cost Methodology

  9. UNECE Convention on Long-range Transboundary Air Pollution In US cost estimation tools developed by EPA for FGD for instance, we have: Equipment costs: BMR = Base absorber island cost BMF = Base reagent preparation cost BMW = Base waste handling cost BMB = Base balance of plan costs including: ID or booster fans, new wet chimney, piping, ductwork, minor WWT, etc. BMWW = Base wastewater treatment facility for future use. Total base installed cost BM = BMR + BMF + BMW + BMB The total base installed cost (BM) is then increased by: • A1: Engineering and construction management costs at 10% of the BM cost; • A2: Labour adjustment for 6 x 10 hour shift premium, per diem, etc., at 10% of the BM cost; • A3: Contractor profit and fees at 10% of the BM cost. To obtain the capital, engineering, and construction cost subtotal (CECC) Investment decompositionIn an ideal case, costs should include (BREF Economic and cross media effects) General Cost Methodology

  10. UNECE Convention on Long-range Transboundary Air Pollution The capital, engineering, and construction cost subtotal (CECC) is : CECC = BM and the additional engineering and construction fees (A1 + A2 + A3). Additional costs and financing expenditures for the project are computed based on the CECC. Financing and additional project costs include: • Owner's home office costs (owner's engineering, management, and procurement) at 5% of the CECC; • Allowance for Funds Used During Construction (AFUDC) at 10% of the CECC and owner's costs. The AFUDC is based on a three-year engineering and construction cycle. Escalation is not included in the estimate. The total project cost (TPC) = CECC + additional costs and financing expenditures.
