11. To strengthen the security management of operational nuclear facilities. All the units of nuclear facilities need to strictly abide by the operational guidance and strengthen operational management. The regulating authorities need to strengthen inspection and guide the enterprises to find and eliminate those potential dangers. To strictly approve the new applied nuclear power projects. To promote the nuclear security plan and adjust the mid-to-long term nuclear development plan. Before the nuclear security plan approved, pause the approvals of nuclear power projects including those under planning. Security Inspection Security Management of Operational Facilities Inspection on Projects under Construction Strictly Approve New Projects The Policy Announced by the State Council of China after Nuclear Accident in Japan To organize complete security inspection on the nuclear facilities within our territory right way. Through delicate security assessment, to take measures to smooth away any security loopholes so as to guarantee absolute security. To inspect the nuclear projects under construction. To make the security evaluation on all the nuclear power projects under construction with the most advanced standard. To those projects not reaching the standard, it must be stopped from construction. The inspection on Ningde Nuclear Power Project has been finished and there is no impact to the commencement time and investment budget.

19. National power demand remain strong. In 1H, the national power demand reached 2251.5 billion KWh, with yoy growth of 12.2%. In 1H, power shortage took place in East, North and Central China and the impact is becoming spreading out, earlier and severe. 19 The power demand in major heavy industries like metallurgical, construction material and chemicals grew fast with total power consumed of 748.2billion KWh in 1H, adding 3.8pt in power demand growth. Strong Power Demand & Worsening Power Shortage Source: China Electricity Council Entering into the 12th Five-Year Plan period, the industrialization and urbanization of our country will be promoted and heavy industries will remain in high proportion in national economy. Therefore, the power supply shortage is expected to be further enlarged.

20. Coal Price Continued Hiking Coal Supply and Demand and Price Trend The Companys Contract Coal Fulfillment In 1Q, the coal price was stable at high level. While since the late March, the spot coal price started to hike and kept hiking for 14 weeks. In 1H, the coal inventory of power plants were normal in general. However, due to coal price, transport and supply issues, the coal supply became a problem in certain region periodically.. In 1H, the company has 17.78million tons of contract coal delivered, with the delivery ratio of 88%,which is about 6 percent higher than 1H 2010. The average standardized contract coal price was 533.62RMB/ton, rising 5.2% yoy basis. 20 Source: www.China5e.com, The Company data and informationwww.China5e.com

21. Tariff Adjustment in Favor of the IPPs 21 Recent On-grid Tariff Adjustment (Fen/KWh) Main Reasons for on-grid Tariff Increase: The country has raised the thermal power on-grid tariff in certain provinces separately since 1st January 2010, 10th April 2011 and 1st June 2011; The commencement of new units in 2H 2010 in provinces like Jiangsu and Guangdong with higher on-grid tariff has driven up the companys average on-grid tariff 6.2% Corporate Average On-grid Tariff (RMB/MWh) Source: The Company Data and Information, Corporate Announcement

23. General Power Shortage Thermal Utilization Enjoys High Growth It is expected the national average utilization hours in 2011 will reach 4650; the utilization hour of thermal units will reach 5250, about 200 hours higher than that of 2010. It is expected the national peak load in this summer will increase 14% and the capacity shortage will total around 30-40GW in North China, East China, Central China and Southern Grid. While, in Northeast, Northwest and West Inner Mongolia Grid, there is 20GW surplus in capacity. It is expected the national capacity shortage will be around 25- 30GW in the winter peak season. In 2H, the power demand will remain high growth. Affected by the uneven location of new added capacity, imbalanced construction of power plant versus power grid, less new added thermal power capacity, the general power supply compared to demand will be in shortage. 1.Well done in market analysis and forecast and coordinate alternative power generation plan; 2.Well organize the production of hydro and wind power projects to avoid water and wind rejection; 3.Keep on coordination with the grid company after Huhhot Thermal Power Plant return as internal power plant; 4.Try hard to lower the internal electricity usage ratio. Power Demand Will Maintain Strong Growth 23 Source: China Electricity Council, The Companys Data and Information Power Supply Trends in Shortage in 2H Measures to raise Electricity Generations in 2H Structural Power Shortage

24. Coal Price In 4Q, the coal price will rebound Since the 2H, the coal price has been dropping for over 5 weeks In 2H, the BSPI average price has experienced slight dropping over 5 weeks. It is expected to continue till the end of September without contingent occurrence. In 4Q, the North part of China will step into heating season, and the inelastic coal demand will drive the spot coal price up. However, the coal price hike will not be remarkable and unlikely be over the high rate in June. Focusing on Fuel Cost Control To fulfill whole process fuel management and optimize the fuel structure Promote coal blending and increase import coal Lower fuel cost by managing the time lag between coal procurement and storage Strengthen coal delivery by active communications between coal mines and railway Try to raise the thermal coal contract fulfillment ratio 24 Coal Price will drop followed by rising in 2H Source: China Electricity Council, www.china5e.com

25. Main Factors affecting the Earnings in 2H 25 In 2H, the coal price will maintain at high level with high probability of further hiking and this will impact the profitability of coal-fired power plants. Coal Price Tariff Interest Rate Fuel cost-tariff pass through mechanism is still the best way to ease the conflicts between coal price liberalization and tariff regulation. The China Electricity Council suggested the government to adjust the on-gird tariff timely. To control the high inflation, there is still high possibility for the central bank to raise the interest rate in 2H. This will bring more pressure for the fund raising and financial expense control.
