  1. Lessons learnt from Selected Projects to Promote Transfer of Mitigation Technologies Asia and the pacific Regional Workshop on Transfer of Technology as referred to Decision 4/CP.4 17th January 2000 Tadahisa Miyasaka Electric Power Development CO.,Ltd ELECTRIC POWER DEVELOPMENT CO.

  2. Optimal Configuration of power sources SUPPLY SIDE Increased use of nonfossile energies Increasing nuclear share Geothermal, Photoboltaic,wind High Voltage transmission Development of Naturalenergy sources Increased efficiency of supply-side facilities Efficiency improvement of thermal power generation Reduction of transmission& distribution loss Efforts to Reduce CO2 emission (1) Combined cycle generation and Efficiency improvement ofThermal generation ELECTRIC POWER DEVELOPMENT CO.

  3. PR activities aimed at energy conservation DEMAND SIDE Energy Conservation Development and diffusion of highly efficient and energy-saving appliances Enhanced utilization of untapped energy sources Heat recovery from river water, waste incineration facilities Efforts to Reduce CO2 emission (2) ELECTRIC POWER DEVELOPMENT CO.

  4. Activities concerning power sector supported by NEDO in 1998 • Totally 37 projects among 9 countries • 20 Power sector projects included • Natural gas pipeline system optimization in Russia • PCF power plants reconstruction to natural gas in Russia • Power plants reconstruction to gas combined cycle system in Russia and Poland • PCF power plants renovation and reconstruction in Russia • Gas-fired power plants reconstruction to combined cycle system in Russia and Myanmar • PCF power plants renovation and reconstruction in Russia ELECTRIC POWER DEVELOPMENT CO.

  5. Projects • Feasibility Studies for CO2 Reduction from coal-fired thermal power plants in Russia. • Feasibility Studies for CO2 Reduction from coal-fired thermal Power Plants in China. ELECTRIC POWER DEVELOPMENT CO.

  6. Purpose • Finding the most economical and effective measure to reduce CO2 emission from coal-fired power plants. • Considering electric power system and energy demand and supply structure. • Finding promising projects related to coal-fired power stations which are appropriate for Joint Implementation between Russia and Japan in the future • Finding a feasible program to be carried out through Japan’s CDM with China. ELECTRIC POWER DEVELOPMENT CO.

  7. Issues to be studied in Russia. [1] General Study of profile of object country. [2] Macro analysis of power system in the Far Eastern regions of Russia and Siberia. [3] Case Studies for 9 individual coal-fired thermal Power stations. ELECTRIC POWER DEVELOPMENT CO.

  8. Issues to be studied in China. [1] General Study of profile of object country. [2] General Study of existing 300MW coal-fired power plant units. [3] On Site Study of 3 PCF power plants. ELECTRIC POWER DEVELOPMENT CO.

  9. [2] Macro analysis of Power System in the Far Eastern Regions of Russia and Siberia • Identify the cost cost effectiveness. Macro analysis of the power-system has been carried out to study the effect of the CO2 emission reduction projects targeting all coal-fired thermal power plants connected to the grid. ELECTRIC POWER DEVELOPMENT CO.

  10. Far Eastern Regions Amrusk CCP-1 Khabalovsk CCP-1 Blgagove-schensk CCP Partizansk CCP Siberian Region Irkutsk CCP-6 Krasnoyarsk CCP-1 Novo-Kemerovo CCP Irkutsk CCP-10 Irkutsk CCP-11 [2] Prospective Power StationsFor Case Studies. ELECTRIC POWER DEVELOPMENT CO.

  11. [3] Case Studies for 9 Individual Coal-fired Thermal Power Stations • Serving as preliminary F.S. for 9 power stations to be considered as candidate for promising project(s) for future Joint Implementation. ELECTRIC POWER DEVELOPMENT CO.

  12. [3] Case Studies for 9 Individual Coal-fired Thermal Power Stations Study through site-visit and questionnaire (1) Dorogobuzh PS (2) Reftinskaya (3) Troitskaya (4) Novo-Irkutsk (5) Petropavlovsk Kamchatsky Study through questionaire (6) Cherepetskaya (7) Ulan-ude (8) Verkhnetagilska (9) Bogoslovskaya ELECTRIC POWER DEVELOPMENT CO.

  13. [3]Efficiency Improvement Measures • Replace - Replace-1; Replace coal-fired plants to GTCC plants. - Replace-2; Replace units to USC-PCF. • Convert -Convert ;Convert the boilers to use natural gas. Evaluation of cost effectiveness was done by 30yeras on replace and 15years on covert. ELECTRIC POWER DEVELOPMENT CO.

  14. [3] Prospective power plants for F.S. reduction amount & method cost effective order • Dorogobuzh replace-1 (coal & gas) 658.4kt-co2/y 3rd • Troitsk replace-1 & convert (coal) 6,535kt-co2/y 1st • Cherepet replace-1 & 2 (coal) 4,834kt-co2/y 2nd ELECTRIC POWER DEVELOPMENT CO.

  15. [2] General Study of Existing 300MW Coal-fired Power Plant Units. • 100 300MW class coal-fired power plants. (20% of coal-fired power plants.) (1) 75% are made of China. (2) Low thermal efficiency and fall short of designed performance. (3) Reliability of plant facilities are low. ELECTRIC POWER DEVELOPMENT CO.

  16. [3] On Site Study of 3 PCF Power Plants. • Zhouxian (300MW×４；Shandong province) • Louhe(300MW×2；Anhui province) • Yaomeng (300MW×2；Henan province) 1)Poor boiler efficiency and boiler outlet gas’s temp’ is high. 2)Plants stop frequently due to boiler tube leak at water wall. 3)Poor turbine efficiency and vacuum condition of condenser. 4)Turbine casings have caused thermal strain deformation. 5)Only within 100-80% lord change of boilers. 6)Manual operation of lord change,start-up and shut down. ELECTRIC POWER DEVELOPMENT CO.

  17. [3] Efficiency Improvement Measures. • Boiler facilities -Modification; water walls,combustion equip’,air heater -Use of; gas re-circulation system,soot blower -Increase the area of ECO and decrease the area of RH. • Turbine facilities -Replacement; HP turbines,IP turbines,bearings,coupling bolts and nuts -Improving; vacuum condition in the condensers ELECTRIC POWER DEVELOPMENT CO.

  18. CO2 Emission Reduction Effect(1) • Project plan was suggested. Implementation of upgrading 10 300MW made-in-China power units by the year 2010. • The CO2 reduction effect and cost-effectiveness of the project has been examined. ELECTRIC POWER DEVELOPMENT CO.

  19. CO2 Emission Reduction Effect(2) • 184,000t-co2/y at 2010(improve 4% thermal efficiency of plants) (=co2 emission from one 300MW unit for a whole year) ELECTRIC POWER DEVELOPMENT CO.

  20. Technical Findings • Many promising projects for AIJ,CDM schemes in Russia and China. • Thermal Efficiency upgrading achieve not only CO2 reduction but also produce another benefit (reduction of other pollutants and fuel consumption etc). • To move next stage, further detailed study is needed. ELECTRIC POWER DEVELOPMENT CO.

  21. Findings in Financing-1 • Good financing schemes are necessary. -Japanese official funding ex,JBIC ; ODA, S/C,B/C,B/L,untied loan, OIC -Private funding ex,ROT, ROO -International funding ex,IBRD, IFC, EBRD ELECTRIC POWER DEVELOPMENT CO.

  22. Findings in Financing-2 • Risk hedging High risk for commercial base. Governmental guarantee for financing. Low interest schemes for financing. ELECTRIC POWER DEVELOPMENT CO.
