General description of project activity A.1 Title of the project activity: Project Name: Ningxia Shizuishan District Heating System Project Document Version: 01 Finalization Date: 10/10/2008 A.2. Description of the project activity: Ningxia Shizuishan District Heating System Project (hereafter referred to as "the proposed project") developed by Xinghan Municipal Industry (Group) Co.Ltd. of Shizuishan City (hereafter referred to as the "Project Developer") is a centralized heating system project with co-generation plant in Ninghui district of Shizuishan City, Ningxia Hui Autonomous Region in China (hereafter referred to as the "Host Country"). The purpose of the proposed project activity is to introduce a new primary district heating system in Huinong District of Shizuishan City in Ningxia Hui Autonomous Region. The new established primary district heating network is designed for utilisation of surplus heat from 2*300MW cogeneration power units at the Guodian Ningxia Shizuishan Power Plant. The proposed project will construct a primary network pipeline with the length of 36.67 km and 64 substations, which will replace all the decentralized, old boilers with lower heating efficiency. Construction began April 2008 and will be commissioned in November 2008. The proposed project will supply heat to 3.8 million m2 in new building and 3.2million square meters for existing building area individually, which ads up to a total of 3,369,716 GJ per annum. Ningxia Guodian Shizuishan Power plant started operation in December 2003. No heat has been utilized from the plant until the primary work was starting construction in 2008. Through the implementation of the proposed project, surplus heat from Guodian Shizuishan Power Plant would be utilized. Prior to the proposed project, the area within the project boundary was supplied with heat from coal fired boiler houses through existing isolated district heating networks. Accordingly the baseline scenario of the proposed project is as follow and will be fully explained in Section B.4: Continued operation or rehabilitation of an existing [isolated] district heating network(s) (both existing and new buildings can be connected to an existing network) or establishment of a new [isolated] district heating network(s) (for new buildings) covering all buildings within the project boundary without the introduction of a primary heating network. Coal fired boilers in boiler houses, supplying several buildings through a small heat distribution network. The proposed project will improve the energy efficiency of heat supply to the urban area in the city of Shizuishan greatly. The heating efficiency will be fostered by replacing the existing heat supply from old coal fired boilers with a lower efficiency. Due to the implementation of the proposed project activity, the amount of consumed fossil fuel (coal) for local heat supply would be considerably reduced, which will lead to a reduction of greenhouse gas (GHG) emissions corresponding to average 355,045 tonnes of CO2 equivalent per year during the crediting period. PROJECT DESIGN DOCUMENT FORM (CDM PDD) - Version 03 CDM – Executive Board page 3 The proposed project will contribute to sustainable development of the Host Country. Specifically, the project: • Increases employment opportunities in the area where the project is located and thereby contributes to poverty alleviation; • Decease the SO2 emissions to great extent, and the level of CO2 and soot from stokers and industry • Enhances the local investment environment and therefore improves the local economy; • Improves the energy utilization efficiency, important for sustainable development of local or national society; • Promotes the utilisation of CHP (Combined Heat and Power) technology.

Category(ies) of project activity: The proposed project falls into the following scope and category: Sectoral Scopes: Scope 1-Energy Industries (renewable - /non-renewable sources); Category: Energy Efficiency in Heat Production. A.4.3. Technology to be employed by the project activity: The construction of the new primary district heating network, with utilizing surplus heat from Guodian Shizuishan power plant, will create several improvements to the environment and the local citizens. • Make massive reduction to annual reduction of greenhouse gas (GHG) emissions corresponding to average 355,045 tonnes of CO2 equivalent per year during the crediting period. • Supply the thermal energy from the CHP to the final consumers by the introduction of a new primary district heating system. PROJECT DESIGN DOCUMENT FORM (CDM PDD) - Version 03 CDM – Executive Board page 6 • Improve the energy efficiency of heat supply to the urban area in the city of Shizuishan considerable, compared to the existing old coal fired boiler houses in isolated district heating networks. HEAT FLOW: 1. The mid-pressure steam is pumped from the turbine of the plant and will enter into the heat exchanger at the conjunction substation of the residential/commercial primary district heating system. 2. The water in the primary district heating system is heated to 130ºC by the steam via the heat exchanger. 3. Hereafter the water in the primary district system will enter the sub-stations of the secondary district system to heat the water of the secondary district system and be cool down to 70 ºC. 4. The water in the primary network will be directed back to the conjunction station and be heated by steam again. 5. The water in the secondary district system will be heated to 90 ºC and sent to the final residential/commercial consumers for meeting the heating demand. 6. Then the water in the secondary district system will be cool down to 65ºC and go back to substation and be heated again to supply heat for consumer. Prior to the implementation of the proposed project, the area in the project boundary was supplied with heat from coal fired boiler houses through existing isolated district heating networks. Accordingly, the baseline scenario of the proposed project is as follow and will be fully explained in Section B.4: Continued operation or rehabilitation of an existing [isolated] district heating network(s) (both existing and new buildings can be connected to an existing network) or establishment of a new [isolated] district heating network(s) (for new buildings) covering all buildings within the project boundary without the introduction of a primary heating network. Coal fired boilers in boiler houses, supplying several buildings through a small heat distribution network. The main greenhouse gases involved in the proposed project activity is CO2; the emissions sources involved in the proposed project activity are the coal consumption in CHP for power generation and heat generation. The lifetime of the new primary district heating system in the proposed project is 27 year (including 1 year of construction). The main equipments included in the baseline and the proposed project activity is listed as following: Existing heating only boilers The existing local coal fired boilers that have been the main heat resource of Huinong District, Shizuishan City prior to the project activity were very small with installed capacity less than 14MW. The boilers have a very low thermal efficiency and do not have any flue gas cleaning equipment or low chimneys whish add to the local air pollution. The old coal boilers would continue to be used in the absence of the project activity. For the conservative purposed, the default value of thermal efficiency of the methodology AM0058 is applied as 80% for the existing coal fired boilers and 85% for the new coal fired boilers. The average remaining lifetime of the boilers is 11.95 years which is more than the crediting period (10 years).
