1 Thirt-eighth meeting Draft baseline and monitoring methodolog AM00XX Baseline and monitoring methodolog for new grid connected power plants using waste gas fired Combined Ccle Gas Turbine technolog instead of more GHG intensive technolog I. SOURCE, DEFINITIONS AND APPLICABILITY Sources This baseline and monitoring methodolog is based on elements from the following approved baseline and monitoring methodologies and proposed new methodologies: ACM0007: Methodolog for conversion from single-ccle to combined ccle power generation ; ACM0011: Consolidated baseline methodolog for fuel switching from coal and/or petroleum fuels to natural gas in existing power plants for electricit generation ; ACM0012: Consolidated baseline methodolog for GHG emission reductions from waste energ recover projects ; ACM0013: Consolidated baseline and monitoring methodolog for new grid connected fossil fuel fired power plants using a less GHG intensive technolog ; ACM0002: Consolidated methodolog for grid-connected electricit generation from renewable sources (Version 7) ; NM0292: Baseline and monitoring methodolog for new grid connected power plants using waste gas fired Combined Ccle Gas Turbine technolog instead of more GHG intensive technolog proposed b ThssenKrupp Steel AG. This methodolog also refers to the latest approved versions of the following tools: Tool for the demonstration and assessment of additionalit; Tool to calculate the emission factor for an electricit sstem. For more information regarding the proposed new methodologies and the tools as well as their consideration b the Executive Board please refer to < Selected approach from paragraph 48 of the CDM modalities and procedures Emissions from a technolog that represents an economicall attractive course of action, taking into account barriers to investment. Definitions For the purpose of this methodolog, the following definitions appl: Rankine ccle mode of electricit generation. The Rankine ccle is a thermodnamic ccle used to generate electricit in a power station. Superheated steam is generated in a boiler, and then expanded in a steam turbine. The steam turbine drives a generator, to convert the work into electricit. The remaining steam is then condensed and reccled as feed-water to the boiler. 1/21

2 Thirt-eighth meeting Open/single ccle gas turbine. Gas turbines are described thermodnamicall b the Braton ccle, where the ambient air is suctioned, mixed with the fuel and combusted in a gas turbine, producing gases at a high temperature. The gas turbine extracts energ from a flow of hot gas produced b this combustion of gas or fuel oil in a stream of compressed air. In a Braton ccle, a gas turbo-generator produces electricit and the waste gas/heat from the gas turbine is lost to the environment/vented to the atmosphere. Combined ccle gas turbine. A combined ccle gas turbine combines two thermodnamic ccles (i.e. the Rankine ccle and the Braton ccle) to result in improved overall efficienc of electricit generation. A gas turbo-generator produces electricit and the waste heat is converted into steam to generate additional electricit in a steam turbine, the latter contributing to the overall increase in efficienc. Waste Gas/Heat. A b-product of gas or heat from machines and industrial processes with the potential to produce useful energ. Examples are blast furnace gas, coke oven gas, basic oxgen furnace gas. Auxiliar fuel. The auxiliar fuel used in the steam and/or gas turbine for start-up of the power plant. The auxiliar fuel ma be, inter alia, natural gas, fuel oil, or coal. 1 Supplementar fuel. The supplementar fuel used to improve the performance of the ccle. Its consumption is associated with the Heat Recover Steam Generator (HRSG) increasing the waste heat generated from the gas turbine and producing additional steam for use in the steam turbine. Applicabilit This methodolog applies to project activities that construct and operate a grid-connected combined ccle electricit generation power plant in a new iron and steel production facilit, using waste gas such as blast furnace gas, coke oven gas, and converter gas sourced from the same facilit. The methodolog is applicable if the power generated in the project activit is used within the industrial facilit and/or exported to the grid b the industrial facilit. Coke oven and steelmaking facilit has been determined before the project activit is considered. This condition is necessar to ensure that the expected production of waste gases from the steel and iron facilit can be estimated with high certaint. In addition, the applicabilit conditions included in the tools referred to above appl. For project activities that involve retrofit of existing facilities with the conversion of single to combinedccle power generation, project proponents ma use the approved and consolidated methodolog ACM The auxiliar fuel is expected to represent less than 2% of energ input after the period of start-up the steel works, when working under normal operational conditions. 2/21

3 Thirt-eighth meeting II. BASELINE METHODOLOGY PROCEDURE Identification of the baseline scenario For the identification of the most plausible baseline scenario, project proponents shall appl the following step-wise procedure. Step 1: Identif plausible baseline scenarios The identification of alternative baseline scenarios should include all possible realistic and credible alternatives that provide outputs or services comparable with the proposed CDM project activit (including the proposed project activit without CDM benefits), i.e. how the electricit needs for the productive process of the power plant owner would have been provided in the absence of the project activit. In the baseline scenario, the electricit demand of a specific industrial facilit in the iron & steel sector shall be satisfied, as the main priorit is to meet the internal demand of the facilit (with a captive power plant). However, for some plant configurations (e.g. in cases where there are no hot or cold rolling activities on site), power surplus ma be generated and supplied to the grid. The same rationale for baseline emissions is emploed, in either case. The realistic and credible alternatives should be determined regarding: What would be the use of the energ from the waste gas in the absence of the CDM project activit? How would electricit be provided to the iron & steel facilit, in the absence of the CDM project activit? When determining what would be the use of the energ (E) from the waste gas, alternatives to be analzed should include, inter alia: E1: The use of the energ for electricit generation onl; E2: The use of the energ for heat purposes onl; E3: The use of the energ for electricit generation and heat purposes; E4: The energ is not recovered and no use is made of it. When determining the possible use of the energ, project proponents shall consider the facilit s energ demand, using, inter alia, energ flow diagrams of the industrial complex. When determining how electricit would be provided (P), the alternatives to be analzed should include, inter alia: P1: The electricit is generated b a combine ccle (CGCT) captive power plant; P2: The electricit is generated b a captive power plant withopen/single ccle gas turbine(s) without energ recover; P3: The electricit is generated b a captive power plant with steam turbine(s) on Rankine ccle mode of electricit generation; P4: Import of electricit from the grid or from connected grid sstems, including the possibilit of new interconnections. 3/21

4 Thirt-eighth meeting Electricit consumed in the iorn and steel facilit will primaril be provided b the captive power plant; in case it cannot satisf the demand, the facilit will be supplied b the electric grid. When establishing the possible combinations of scenarios, taking into consideration the alternatives for the use of the energ generated from waste gas and the alternatives for technologies of electricit generation, project proponents should clearl identif and document which tpe of fuel would be used in each of them, taking into account the requirements of the technolog and the market practices within the relevant sector and selected region (i.e. host countr). These alternatives do not need to consist solel of power plants of the same capacit, load factor and operational characteristics (i.e. several smaller plants, or the share of a larger plant ma be a reasonable alternative to the project activit); however the should deliver similar services (e.g. peak vs. base load power). It must be ensured that all relevant power plant technologies that have recentl been constructed or are under construction or are being planned (e.g. documented in official power expansion plans) are included as plausible alternatives. A clear description of each baseline scenario alternative, including information on the technolog, such as the efficienc and technical lifetime, shall be provided in the CDM-PDD. Table 1 demonstrates the possible combinations of baseline scenarios, considering the waste gas energ use (E) and the electricit provision (P). Table 1: Combinations of baseline options and scenarios applicable to this methodolog Scenario Baseline Options Energ use from waste gas Electricit provision Description of the situation I E1 P1 The energ from the waste gas is used for electricit generation in a captive power plant using CCGT technolog. II E1 P2 The energ from the waste gas is used for electricit generation in a captive power plant with a generation technolog different from CCGT, such as gas turbine(s) on open/single ccle without energ recover. III E1 P3 The energ from the waste gas is used for electricit generation in a captive power plant with a generation technolog different from CCGT, such as steam turbine(s) on Rankine ccle. IV E2 P4 The energ from the waste gas is used for heat purposes onl and electricit is imported from the grid or existing or new power plants connected to the grid. V E3 P1 The energ from the waste gas is used for electricit and heat purposes and electricit is obtained from a captive waste gas-fired power plant using CCGT technolog. VI E3 P2 The energ from the waste gas is used for electricit and heat purposes and electricit is generated in a captive power plant, with a generation technolog different from CCGT, such as gas turbine(s) on open/single ccle mode without energ recover. 4/21

5 Thirt-eighth meeting VII E3 P3 The energ from the waste gas is used for electricit and heat purposes and electricit is generated in a captive power plant with a generation technolog different from CCGT, such as steam turbine(s) on Rankine ccle. VIII E4 P1 The energ from the waste gas is not recovered and the electricit is generated b a captive power plant using other fuels with CCGT technolog. IX E4 P2 The energ from the waste gas is not recovered and the electricit is generated b a captive power plant using other fuels with a generation technolog different than CCGT, such as gas turbine(s) on open/single ccle without energ recover. X E4 P3 The energ from the waste gas is not recovered and the electricit is generated b a captive power plant using other fuels with a generation technolog different from CCGT, such as steam turbine(s) on Rankine ccle. XI E4 P4 The energ from the waste gas is not recovered and electricit is imported from the grid or from existing or new power plants connected to the grid. Project proponents shall exclude baseline scenarios that are not in compliance with all applicable legal and regulator requirements. If one or more scenarios are excluded, appropriate explanation and documentation to support the exclusion of these scenarios shall be provided. Step 2 Project proponents shall eliminate the alternative scenarios that are not feasible. Those non-feasible scenarios ma be clearl be economicall unattractive when compared with other alternatives. The latest approved version of the Tool for the demonstration and assessment of additionalit shall be used as reference to compare the different alternatives. Step 3 If more than one credible and plausible alternative scenario remains, the alternative with the lowest baseline emissions shall be considered as the most likel baseline scenario. This methodolog is onl applicable if the most plausible baseline scenario is the construction of (a) baseline power plant(s) using the same fuel tpe and quantit as used in the project power plant, for electricit generation. Moreover, this methodolog is onl applicable if electricit generation in the baseline is identified to be open/single gas turbine(s) ccle (without energ recover) or steam turbine(s) on Rankine ccle. (Scenarios II & III of Table 1) Additionalit Project proponents shall demonstrate additionalit using the latest approved version of the Tool for the demonstration and assessment of additionalit agreed b the CDM Executive Board. The assessment of additionalit comprises the following steps: 5/21

6 Thirt-eighth meeting Step 1: Identification of alternatives to the project activit consistent with current laws and regulations When appling Step 1 of the tool, project proponents shall use the same set of alternative scenarios identified in Step 1 of the procedure Identification of the baseline scenario. The will then proceed to Step 2 (Investment analsis) or Step 3 (Barrier analsis). Project proponents ma also select to complete both Steps 2 and 3. Step 2: Investment analsis Determine whether the proposed project activit is not: (a) The most economicall or financiall attractive; or (b) Economicall or financiall feasible, without the revenue from the sale of certified emission reductions (CERs). Step 3: Barrier Analsis Project proponents shall establish that there are realistic and credible barriers that would prevent the implementation of the proposed project activit from being carried out if the project activit was not registered as a CDM activit. Step 4: Common practice analsis Project proponent should identif if there are another operational power plants that uses waste gas that are similar to the proposed project activit.

8 Thirt-eighth meeting Baseline emissions Baseline emissions ( BE ) are calculated as the amount of additional electricit (MWh) generated b the project ( EG Pr, ) in a given ear multiplied b the CO 2 emission factor of the grid (tonnes CO 2 /MWh) for the ear in which it is generated, as follows: BE EGPr, EFgrid, (1) BE grid Baseline emissions in ear (MWh) EF, CO 2 emission factor for the electricit interconnected grid (tco 2 /MWh) EG Pr, Additional quantit of electricit generated b the project activi in ear (MWh) The emission factor for the electricit displaced due to the project activit ( EF grid, ) should be calculated as the combined margin emission factor (CM) obtained appling the latest version of the Tool to calculate the emission factor for an electricit sstem. EG Pr, The quantit of additional electricit generated b the project ( ) in a given ear is equal to the total quantit of electricit generated b the project activit power plant 2 ( EG Pr, ) less the quantit of electricit that could be generated b the baseline scenario power plant ( EG, ).

For determination of the top 15% efficient power plants, the following step-wise approach is used: Step 1: Definition of similar plants to the baseline power plant for the geographical area The sample group of similar power plants for the geographical area shall consist of all power plants: In the iron & steel sector, using similar technolog and waste gas as fuel that the baseline power plant would use; That have been constructed in the previous five ears before the starting date of the project activit; That have comparable size to the baseline power plant, defined as a range from 50% and 150% of its rated capacit; and 3 In case of non availabilit of data, Option 2 shall be used for calculating the efficienc of the baseline power plant. 9/21

10 Thirt-eighth meeting That are operated in the same load categor, i.e. at peak load (defined as a load factor of less than 3,000 hours per ear) or base load (defined as a load factor of more than 3,000 hours per ear) as the baseline power plant. Step 2: Definition of the geographical area The geographical area to identif similar plants to the baseline power plant should be chosen in a manner that the total number of power plants j, built in the last five ears prior the implementation of the project activit, comprises at least 10 plants. As a default, the electricit grid sstem where the project activit is implemented should be used as the geographic area. If the number of similar plants, as defined in Step 1, within the grid boundar is lower than 10, the geographical area should be extended to the host countr. Step 3: Identification of the sample group Identif all power plants n that are to be included in the sample group. Determine the total number N of all identified power plants that use the same fuel as the baseline power plant and an technolog available within the geographical area, as defined in Step 2 above. The sample group should also include all power plants within the geographical area registered as CDM project activities, which meet the criteria defined in Step 1 above. Step 4: Determination of the plant efficiencies Calculate the operational efficienc of each power plant n identified in the previous step. The most recent one-ear data available shall be used. The operational efficienc of each power plant n in the sample group is calculated as follows: η n, x 3. 6 WG n, x EG n, x NCV WG, x (5) η n,x Operational efficienc of the power plant n in the ear x EG, Net electricit generated b the power plant n in the ear x (MWh) n x WG n, x Quantit of waste gas used for electricit generation b the power plant n in ear x (mass or volume unit) NCV WG, x Net calorific value of the waste gas fired in power plant n in ear (GJ/mass or volume unit) 3.6 Conversion factor from GJ to MWh n x Power plants in the defined geographical area that have a similar size, are operated at similar load and use the same fuel tpe as the baseline power plant Most recent ear prior to the start of the project activit for which data is available 10/21

11 Thirt-eighth meeting Step 5: Identification of the top 15% performer plants j Sort the sample group of N plants from the power plants with the highest to the lowest operational efficienc. Identif the top 15% performer plants j as the plants with the 1st to Jth highest operational efficienc, where the J (the total number of plants j) is calculated as the product of N (the total number of plants n identified in Step 3) and 15%, rounded down if it is decimal. 4 If the generation of all identified plants j (the top 15% performers) is less than 15% of the total generation of all plants n (the whole sample group), then the number of plants j included in the top 15% performer group should be enlarged until the group represents at least 15% of total generation of all plants n. Step 6: Identification of the energ efficienc of the power generation technolog that has been identified as the most likel baseline scenario It is calculated as follows: η BL, x j η J j. x (6) η Energ efficienc of the power generation technolog that has been identified BL,x as the most likel baseline scenario η Operational efficienc of the top 15% performers power plants j in the ear x J j,x The top 15% performers power plants All steps should be documented transparentl; including a list of the plants identified in Steps 3 and 5, as well as relevant data on the fuel consumption and electricit generation of all identified power plants. Option 2: The project participant shall identif all the technolog tpes that are implemented in the host countr and request at least three manufacturers to provide the data on the highest efficiencies of the most recent available version of these technologies. The highest efficienc among the technologies should be used as the efficienc for the baseline scenario. In both Options 1 and 2, Project emissions ηbl, x is updated at the renewal of a crediting period. Project emissions ( PE ) are the emissions from the auxiliar use of fossil fuel to operate the gas turbine ( PEGT ) and the emissions from the supplementar use of fossil fuel to operate the steam turbine ( PEST ) PE PEGT + PEST (7) 4 This is conservative as this limits the number of the top 15% performer plants, which will alwas lead to exclusion of the least efficient plant among them. 11/21

If not, project proponents can use default values from the IPCC 2006, volume 2, Table The CH 4 emissions can be ignored while appling this methodolog if project proponents demonstrate through estimation that these are a negligible fraction of the baseline.

In order to assess the continued validit of the baseline, project proponents should appl the procedure to determine the most plausible baseline scenario, as outlined above. When re-determining the baseline scenario and the baseline emission factors at the start of each subsequent crediting period, all relevant legal, regulator and technological changes shall be incorporated.

17 Thirt-eighth meeting III. MONITORING METHODOLOGY All data collected as part of monitoring should be archived electronicall and be kept at least for 2 ears after the end of the last crediting period. 100% of the data should be monitored if not indicated otherwise in the tables below. All measurements should be conducted with calibrated measurement equipment according to relevant industr standards. In addition, the monitoring provisions in the tools referred to in this methodolog appl. Project proponents shall describe and specif in the CDM-PDD all monitoring procedures, including the tpe of measurement instrumentation used, the person responsible for monitoring and QA/QC procedures that will be applied. Where the methodolog provides different options (e.g. use of default values or onsite measurements), specif which option will be used. All meters and instruments should be calibrated regularl as per industr practices. The qualit manual necessar under the above mentioned QA/QC standards shall include a section describing the elements of the CDM related monitoring procedures and how to assure and control their qualit. A qualit management representative from the project proponents shall ensure that the monitoring procedures are established and that the meet the requirements as specified in this methodolog. Project proponents should establish a sstem to monitor the amount of all tpes of fossil fuel combusted. On-site fossil fuel consumption for the operation of the power plant should be metered through flow or volume meters or respectivel with an energ balance over the ear, considering stocks at the beginning and at the end of each ear. Where possible, project proponents should cross-check these estimates with fuel purchase receipts. The following table lists the data to be collected or used in order to monitor emissions from the project activit. Monitoring of the inputs required for calculating baseline and project emissions include: Annual fuel(s) consumption in the project activit; Annual electricit generated in the project activit; Annual electricit required to run the project activit power plant; Net Calorific Value of fuel(s) used in the project activit; Emission factor(s) of the auxiliar and supplementar fuel(s) used in the project activit. Grid Emission Factor. If applicable, this shall be based on a combination of bills of lading records or measurements records, in accordance with the measuring instruments available at the power plant.
