Title of the JCM project 5.7 MW biomass power generation project Sri Lanka Carbon Fund, Moneragala, Sri Lanka A.2. General description of project and applied technologies and/or measures The project is to generate 40,075MWh of electricity per year by combusting Gliricidia Sepium species, one of the most popular renewable wood biomass resources in Sri Lanka. Electricity to be generated through project implementation will be sold to the Ceylon Electricity Board who is the owner and the management body of the Sri Lankan National Grid, in accordance with the Standard Power Purchase Agreement signed with them. The expected amount of electricity to be sold to the Ceylon Electricity Board is 5,000kwh per hour, while the remaining 700kWh per hour will be consumed to run the power plant. Technologies to be employed for the project are a set of 23t/h travelling grate biomass boiler with steam supply at 485c / 67kg/cm2, a set of bleed cum condensing system & multi stage steam turbine, gears, alternator with power generation capacity of 5.7 MW and other related facilities & equipment. Thermax Instrument Limited, an Indian engineering company will enter into an agreement as an Engineering, Procurement and Construction (EPC) with the project owner and take full responsibility on full turnkey basis.

2 Gliricidia Sepium species is considered as the sole source of energy for power generation in the project. A survey conducted by one of the prominent research companies that is also registered as a biomass consultant at the Sri Lankan sustainable energy authority concluded that approximately 15.8 million Gliricidia Sepium trees are available in the area. As there is no demand for biomass from Gliricidia Sepium trees in the area, the number of Gliricidia Sepium trees is sufficient for the project owner to operate power plant with capacity up to 8.58MW in the area.

Name of project participants Sri Lanka Sri Lanka Carbon Fund (PVT) Limited Japan Obayashi Corporation (under consideration) A.5. Duration Starting date of project operation July 2015 Expected operational lifetime of project 20 years A.6. Contribution from developed countries The project will contribute to the host country in terms of ; 1. Reducing GHG emission, electricity to be generated through project implementation will replace the GHG emission that would have been generated at existing power plants, including fossil fuel thermal power plants, connected to the national grid 2. Reducing deficits on trade as well as improving energy security of the host country, as energy to be utilized through project operation will be able to replace fossil fuels. Currently Sri Lanka imports the total amount of fossil fuel consumed domestically from overseas. 3. Job creation and poverty reduction in the rural areas and adjustment of socio-economical imbalance between urban area and rural area, as the project owner will 1) hire employees at project site and biomass pre-treatment site and 2) enter into agreements with a large number of residents in the area to supply biomass and will purchase biomass fuels from them. B. Application of an approved methodology(ies) B.1.

Explanation of how the project meets eligibility criteria of the approved methodology Eligibility Descriptions specified in the methodology Project information criteria Criterion 1 The project installs a new power generation facility(ies) with installed capacity up to 10MW. The project is designed to utilize biomass resources to generate up to 5,700 kwh of electricity per hour (installed capacity is Criterion 2 The project sells electricity to the national grid and replaces the grid electricity generation. Criterion 3 The net amount of electricity sold to the national grid, amount of biomass resources used for power generation and fuel consumption in the project shall be measurable based on the monitoring plan after the project starts. Criterion 4 The biomass resources used in the project shall comply with one of the following conditions: a) the biomass resources are mentioned in the national guideline set by the Government of Sri Lanka Guideline for Biomass Assessment in Sri Lanka as energy source materials and the amount of biomass resources to be used by the project does not exceed the potential biomass supply estimated in the guideline in the biomass collection area of the project, b) the biomass resources used in the project are produced from plantation which is not included in the potential biomass supply estimation in the guideline, c) the biomass resources used in the project 5.7MW) and export 5.0 MW of electricity to the National Grid. Thus the project completely satisfies the eligibility criterion 1 and 2. The amount of electricity to be exported to the national grid is planned to be measured by the electricity meter. The amount of biomass resources to be utilized for power generation is planned to be weighed by weighing scale and the amount of fossil fuel to be consumed at project site is planned to be measured by the flow meter. Thus the project completely satisfies the eligibility criterion 3. The project is ordered by the Central Environment Authority to utilize only Grilicidia as fuel wood for plant operation (Environmental Recommendation issued by the Central Environmental Authority with Reference No. UPO/MG/07/02/14/2010) and Grilicidia is identified as one of the recommended fuel sources in Sri Lanka in the Guideline for Biomass Assessment of Sri Lanka. Thus the project completely satisfies the eligibility criterion 4. II-3

4 are approved by the Sri Lankan Government as harmful plants which should be removed from the area. Criterion 5 Processed biomass resources such as pellets, briquettes and bio-cokes shall not be applicable to this methodology (Wood chips are not regarded as processed biomass resources). Criterion 6 Power generation efficiency in the specification of the facility is beyond 25%. The power generation efficiency can be defined as amount of electricity generated by the facility divided by the input energy to the turbine. Criterion 7 In the case where biomass is procured by the plantation, all the following conditions shall be satisfied. a) any chemical fertilizer or chemical pesticides/ herbicides should not be used. b) the land for the plantation should not be categorized as forest, wetland or peat land (organic soil). c) In the case where the plantation is planned to be developed in the land which is categorized as forest area in the Sri Lankan land use regulation, the plantation plan needs to be approved by the Sri Lankan Government as the project with the purpose of rehabilitation of the land which is degraded due to the invasion of the harmful plants. The project is designed to utilize biomass chip with size 25x25x15mm in average by EPC. Thus the project completely satisfies the eligibility criterion 5. The project owner plans to install the power generation unit with efficiency at the rate of more than 25%. Thus the project completely satisfies the eligibility criterion 6. (when the owner finally installs such facility in this project) The project is designed to develop its own and dedicated biomass plantation as a part of its fuel supply source. However the project is designed: a) Not to utilize fertilizer, chemical pesticide / herbicides, b) Not to cultivate the lands where the lands are categorized as forest, wetland or peat land (organic soil), and c) Not to cultivate any lands categorized as forest area by the laws & regulation in Sri Lanka, except for those with invasive foreign species recommended and approved by the Sri Lankan Government to be removed from the area for restoration of former ecosystem in the area. Thus the project completely satisfies the eligibility criterion 7. C. Calculation of emission reductions C.1.
