Development Trends ofChina’s Electric Power GenerationSO 2 Control Technology for Coal-fired plants• A series of environmental protection regulations andstandards have been issued in recent years• SO 2 emissions from industrial coal combustion were19.95 Mt, accounting for 90% of China’s total SO 2emissions, of which 8.9 Mt are from coal-fired powerplants• Acid rain caused by SO 2 emissions have damaged30% of the total area in China• Based on SO 2 emissions level in 2000, the 10 th “Five-Year Plan” for national environmental protectionrequires that SO 2 emissions from power industry bereduced by 10% to 20% by 2005 and 20% for acidrain and SO 2 control areas


Development Trends ofChina’s Electric Power GenerationSO 2 Control Technology for Coal-fired plants• Approximately 100 billion RMB will be invested onSO 2 and acid rain control projects during the 10 th“Five-Year Plan in China• The total SO 2 emission fee was increased from 0.2RMB/kg to 0.63 RMB/kg, started from July 2003• Newly built and upgraded/refurbished coal-fired unitsmust be equipped with FGD system• Newly revised emission standards for thermal powerplants will be issued


Development Trends ofChina’s Electric Power GenerationPollution Control Technology for Coal-fired plants• High efficiency particulate removal systems will bedeveloped to reduce particulate emissions from 200mg/m 3 to 50 mg/ m 3• Different proven FGD systems have beendemonstrated, including wet-limestone process, seawater FGD, electron beam and CFB FGD processes• Application of low NOx combustion systems to meetthe new standards for NOx emissions:– 400 mg/m 3 for bituminous coal-fired boilers– 650 mg/m 3 for anthracite or lean coal-fired boilers– 200 mg/m 3 for some special areas (employ de-NOx plant)


Development Trends ofChina’s Electric Power GenerationGreatly Develop Hydro Power• 6 units each rated at 700 MW at the Three GorgeProject have been successfully put into commercialoperation this year• Pprojected hydro power generating capacity by 2020will amount to 260 GW, which will account for 27.1%of China’s total installed capacity and will account for68.8% of available hydro power• Approximately 30 GW of pumped-storage hydropower station will be built within next 20 years


Development Trends ofChina’s Electric Power GenerationActively Develop Nuclear Power• China’s electricity generation by nuclear power was only 1.5% of thetotal last year, which is much lower than that of the world averagelevel of 16-17%• Strategy for nuclear power changed from “properly development” to“accelerating development”• 8 nuclear power units with a total capacity of 6100 MW have beensuccessfully put into commercial operation• Another 3 nuclear power units with a total capacity of 2600 MW areunder construction• Projected nuclear generating capacity will reach 40 GW by 2020,which will account for 4.2% of China’s total capacity. Nuclear powergeneration will account for 6.1% of China’s total.• 120 Mt of coal, accounting for about 10% of total coal production inChina, will be replaced by nuclear power in 2020


Development Trends ofChina’s Electric Power GenerationProperly develop natural gas-firedand combined cycle unites• Development of natural gas-fired power plants will be an importantmeasure to adjust thermal power composition as well as toimprove environment and operation load flexibility• Current gas turbine generating units (mainly oil-fired) totals to 8000MW, accounting for about 2.2% of the total capacity• Natural gas sources will mainly come from the “Project of NaturalGas from West to East”, east costal and imported LNG inGuangdong and Fujian Provinces• Total Capacity of natural gas-fired units will reach 72 GW by 2020,which will account for 7.5% of China’s total capacity• Annual gas consumption will be 58 billion m 3 , accounting for 40%of China’s total gas consumption.• First 23 9F gas turbines with total capacity of 8000 MW for 10plants have been ordered this year• Another 20 gas turbines units are under procurements


Development Trends ofChina’s Electric Power GenerationDevelop Renewable Power• Projected renewable power capacity, mainly by windand some solar, will be 10 GW by 2020, which willonly account for 1% of China’s total installed capacity• Several 1000-MW wind power plants will be built inthe future• MOST of China has put forward a plan for solarenergy development with 10 billion RMB invested forsolar power generation capacity of 300 MW by 2005• Currently 668 solar power plants have been built inremote rural areas


Concluding Remarks• China’s primary energy resource is and willcontinue to be dominated by coal in theforeseeable future.• China’s electric power generation will continue tobe dominated by coal-fired power generationwithin the next 30 to 50 years.• Development and application of clean, highefficiency, large-capacity, coal-fired powergeneration technology is a long-term strategictask for China• Effective measures taken for restructuringChina’s electric power industry will greatlycontribute to sustainable power development.
