| FY | FY 2008 |
| Main Implementing Entity | E & E Solutions Inc. |
| FS Partner(s) | Shaanxi Haiyan Coke Making (Group) Co., Ltd.; and Tepia Corporation Japan Co., Ltd. |
| Location of Project Activity | China (Longmen town, Hancheng city, Shaanxi province) |

| Description of Project Activity | The coke production lines with total annual production capacity of one million tons will be installed in the Shaanxi Haiyan Coke Making (Group) Co., Ltd. During the coke production process, about 27,400Nm3/hr of Coke Oven Gas (COG) will be produced and be directly emitted to the atmosphere. The proposed project will recover the waste COG and use it as energy source for power generation of 163,800MWh/year In the absence of the proposed project, the same amount of electricity would be purchased from North West Power Grid system (NWPG), which is mainly from fossil fuel fired power plants. As the proposed project uses waste gas to produce electricity, there will be no emission of greenhouse gas involved. The estimated emission reduction of the proposed project is 143,653t/year. |

| CDM/JI | CDM |
| Duration of Project Activity/ Crediting Period | 2009-2019 / 10 years (fixed renewable period) |
| Baseline Scenario (including Methodology to be applied) | The approved methodology applied to the proposed project activity is ACM0012 (Version 03.1) "Consolidated baseline methodology for GHG emission reductions from waste energy recovery projects". The geographical boundary of the project includes the Coke plant generating the COG, the power plant utilizing the recovered COG and the North west power grid (NWPG). The baseline emission sources include the CO2 emitted from the power plants of the NWPG using fossil fuel |
| Demonstration of Additionality | As the proposed project activity is faced the following prohibiting barriers and the registration of the project as CDM will remove such barriers, it is concluded that the proposed project is additional. (1) Investment barrier The IRRwithout revenues from CERs is lower than that of the electricity generation section benchmark then the proposed project is financially unacceptable because of its low profitability. Taking account into the CERs revenue, the IRR of the proposed project is higher than the benchmark and the financial attraction will be improved. (2) Common practice According the case study of the COG utilization projects of coke making plants in Shaanxi province, there is no similar project which recover COG for power generation without applying CDM scheme. |
| Estimation of GHG Emission Reductions | The amount of emission reduction of the project is estimated to be 143,653tCO2/year, and 1,436,526tCO2 for whole crediting period of 10 years. |
| Monitoring Plan (including Methodology to be applied) | Annual electricity delivered by the proposed project, electricity consumption due to the proposed project and quantity of Waste Gas used for energy generation will be monitored according to the methodology of ACM0012. All data collected as part of monitoring plan should be archived electronically and be kept at least for 2 years after the end of the last crediting period. |
| Environmental Impact Analysis | The project, which utilizes waste COG from coke production for electricity generation, has significant environmental and social benefits. It will contribute to the local sustainable development as followings.
|
| Issues and Tasks for Project Materialisation | There is no obstacles or issues to be resolved for the implementation of the project. There are plans to proceed to the validation procedure as soon as the PDD is finalized after this study has been finished. |
| Co-benefits Effects | 97t of SO2 can be removed by the desulfurizer which is installed in the project. 1,062ｔ/year of SO2 generation is reduced as the energy saving advantage. |
