Energy Supply to Sustain Economic Growth Increased demand on energy supply, less energy intensive, and sustainability 1. The 11 th Five-Year Plan (2006-2010) doubling the GDP (2000 - 2010) Improving efficiency reducing energy consumption per unit GDP by 20% (2005 to 2010) Power sector: installation of large-sized, high-efficiency thermal generators and scale up efficiency improvement 2. The medium and Long Term Energy Conservation Plan reducing energy consumption per unit GDP by 2.2% power sector highlighted for efficiency improvement
3
Coal as a Dominant Energy Source Coal accounts for about 65% primary energy supply in China, and will remain dominated until 2020. CHALLENGES: 1. Long-term Energy Security Providing affordable and reliable energy supply - 40% oil imported 2. Local Environmental Impacts acid rains impact on agriculture and food security SO 2 emissions will double and NOx emission will triple from 2000 to 2020 particulates impact on population health cost of exposure to particulates for urban residents expected to rise from $32 billion in 1995 to $98 billion in 2020 (WB: China 2020) 3. Global Environment Impacts – Climate Change High coal consumption is leading to increased GHG emission
4
CO 2 emission from fossil fuel consumption (Billion tons) GHG Emission China’s CO 2 emissions are expected to increase from 3.3 billion tons in 2000 to 5.7 billion tons in 2020 (IEA 2004)

China Thermal Power Efficiency Project - proposed for GEF Grant (US$19.7 million) The project is designed to offer a systematic program to increase the overall efficiency of China’s coal-fired power plants The project is designed to offer a systematic program to increase the overall efficiency of China’s coal-fired power plants –Phase-out small-sized –Facilitate investment in rehabilitation / retrofitting of in-efficient thermal units through technical capacity building and demonstration There are three components: There are three components: –Enhancement and Enforcement of Sector Regulation on EE A mandatory and incentive approach A mandatory and incentive approach –Efficiency Improvement Demonstration Project (Rehabilitation) –Technical Capacity Building
11
China Thermal Power Efficiency Project - Rehabilitation and technical capacity building Efficiency Improvement Demonstration Project -- Rehab. Identify about 10 sets of potential units in different categories of unit size Identify about 10 sets of potential units in different categories of unit size Technical auditing and justification (economic, financial, reliability) Technical auditing and justification (economic, financial, reliability) –Packaged solutions to unit / plant efficiency improvement –Financial justification / cost-effectiveness of individual as well as packaged solutions –Including environment project when possible – regulation requirements on emissions, financial implication to plant owner –Market demand and implementation schedule Development of new business and financing models for rehabilitation Development of new business and financing models for rehabilitation –Competing with other initiatives on plant own working capital (annual budget for Technical Renovation Funds) Rehabilitation of units & plants for demonstration Rehabilitation of units & plants for demonstration –about 57 units of 200MW and 57 units of 300 MW have similar type of technologies/design (double-flow turbines) Technical Capacity building TA to technology development and/or transfer to lower down cost of rehabilitation and to explore further efficiency increase potential TA to technology development and/or transfer to lower down cost of rehabilitation and to explore further efficiency increase potential Creation of awareness and dissemination of knowledge Creation of awareness and dissemination of knowledge

Project ComponentsLocal Financing GEF Grant Estimated Total (US$m) 1.Enhancement of Regulation on Energy Efficiency 1.53.65.1 2. Efficiency Improvement Demonstration Project 85.5 (79) 8.594 3. Technical Capacity Building6.67.614.2 Total Project Costs93.619.7113.3 China Thermal Power Efficiency Project - project cost and financing Total cost estimation: $113.3 million US$93.6 million in counterpart funds, covering 100% of the capital investment in demonstration (US$79 million) and partial cost of technical assistance activities US$19.7 million GEF Grant, contributing to the cost of technical assistance activities
13
China Thermal Power Efficiency Project - GEF financing, carbon financing Carbon financing for rehabilitation – in considerations Baseline: unit or plant itself - coal consumption rate and output (kWh) before rehabilitation ERs – reduced coal consumption for same amount of output (kWh) after rehabilitation Methodologies – to be developed GEF financing – contributing partially to the cost of Policy and regulation enhancement Technical auditing (bring international best practices when possible) Technical capacity building – rehabilitation technology, plant service efficiency Knowledge dissemination for replication
