3Background Only a portion of the solar energy hits the Earth The remainder either returns to spaceOr is absorbed by the atmosphereUpon contact with the incident radiation, the Earth heats up and emits this energy in the form of infrared radiant heatDirected towards space, a portion of this radiation is intercepted and absorbed by the greenhouse gases.
4The Greenhouse EffectThe Greenhouse Effect is a natural phenomenon that allows us to survive on Earth. Without the greenhouse effect, average global temperatures would be – 18oC rather than the current 15oC.The green house effect is the process by which absorption and emission of infrared radiation by the gasses in the atmosphere warm planets lower atmosphere and surface. It was proposed by Joseph Fourier in 1824 and investigated quantitatively by Svante Arrhenius in 1896.Global Warming is an increase in the average global temperatures caused by an increase in concentration of gases that trap the sun’s energy.The global mean surface temperature increased over the 20th century by about 0.6oC.
5Resulting Impact Snow cover and ice extent have decreased; Global average sea level has risen and ocean heat content has increased.Higher maximum temperatures and more hot days over nearly all land areas;Higher minimum temperatures and fewer cold days and frost days over nearly all land areas;More intense precipitation over numerous regions;Increased summer continental drying and associated risk of drought over most middle latitude continental land areas;Increase in number of infectious diseases due to higher nocturnal temperatures (malaria already reaching higher altitudes where it was previously unknown).Fall in agricultural production of staple crops such as wheat and corn due to higher temperatures.
6Sources Green House Gasses Carbon Dioxide (CO2) – Stems from combustion of fossil fuels, linked to transport and the production of heat or electricity, certain industrial process; deforestation.Methane (CH4) – Stems from agriculture, oil and gas activities, and waste management activities.Nitrous Oxide (N2O) – Stems from agriculture, the chemical industry and combustion activities.Sulfur Hexafluoride (SF6), Per fluorocarbon (PFC), and Hydro fluorocarbon (HFC) stem from specific industrial processes (manufacture of aluminum, or magnesium, the semi-conductor industry), and from aerosols, air conditioning and insulating foam.
7The Kyoto Protocol 1997 International treaty signed in Kyoto Japan: Sets an emission reduction target for 40 industrialized nations: Overall, nations must reduce GHG emissions by 5% below 1990 levels.Because each GHG is different and has different global warming impacts, emission reductions described in tCO2-eq.1 tonne of CO2 = 1 tCO2-eq=1 carbon credit1 tonne of CH4 = 21 tCO2-eq=21 carbon credits1 tonne of N2O=310 tCO2-eq=310 carbon credits1 tonne of PFC = 9,200 tCO2-eq= 9,200 carbon credits.1 tonne of SF6 = 23,900 tCO2-eq=23,900 carbon credits
8IMPACT OF EMISSIONS FROM ELECTRICITY GENERATED On average, each Mega Watt hour (Mwh) of electricity generated in the U.S results in the emission of 1,341 pounds of carbon dioxide (CO2), 7.5 pounds of sulphur dioxide (SO2) and 3.55 pounds nitrogen oxide (NOx). Thus the 10 million Mwh of electricity generated annually by US. Wind farms represents about 6.7 million tons in avoided CO2 emissions, 37,500 tons of SO2 and 17,750 tons of NOx. This avoided CO2 equals over 1.8 million tons of carbon, enough to fill 180 trains, each 100 cars long, with each car holding 100 tons of carbon every year.

10Kyoto Protocol and Carbon Credits Provides financial incentives for investors in developing countries to invest in most efficient and environmentally friendly technologies;Facilitate the most cost-effective reductions of GHGsIt costs comparatively less to reduce one tonne of CO2 in developing Countries than in the developed countries.It helps developing countries continue on path of industrialization and leapfrog over most pollution-intensive stages;
11How to Implement Carbon Credit Projects Invest in new, cleaner, more efficient technologies, such as the following:Construct and operate a wind farm or hydropower plant – will displace electricity produced from fossil fuels;Application of biomass fuels instead of fossil fuels, such as rice husk, biogases, or MSW instead of coal;Capture waste heat to produce additional electricity, thereby reducing overall fuel consumption;Replace older, less efficient equipment with newest models available in the market.It is to ensure that investment in technology goes above and beyond the environmental performance of the business-as-usual scenario in the country.
12Carbon Credit Project Process The project must first be approved by host country and validated by a third-party auditor.After validation, the project is submitted to the United Nations for approval by the Clean Development Mechanism Executive Board.For validation and approval, the project must first meet certain eligibility criteria, as well as use an approved methodology for determining emission reductions.Subsequent approval, the project is closely monitored to ensure that emission reductions are achieved. Monitoring data will be evaluated by a third-party auditor.Carbon Credits are only issued once monitoring data are verified by the auditor and the issuance is approved by the United Nations.

14CriteriaCountry is a signatory to the international treaty to climate change and has ratified Kyoto Protocol and set up DNA for approve projects.Project must reduce/displace one of the six greenhouse gases.Project must not have been commissioned yet.Emission reductions should be additional to emission reductions that would occur under normal business-as-usual scenario.Required funding must not divert official development assistance.Project must contribute to the country’s sustainable development.Project must use technology that is readily available in a market.
15CriteriaCarbon Credit revenue essentially to be a part of feasibility study. If a project has already commissioned – and it has not got carbon credits– that means it did not need carbon credits in the first place.Carbon credits are intended to provide a financial incentive to invest. But if one has already invested without considering carbon credits, apparently such incentive was not required.
16AdditionalityThe Clean Development Mechanism provide financial incentives to invest in new / more efficient / cleaner technologies.It is essential to prove Additionality.Carbon credit revenue need to play a role in decision-making while considering investing in a project!What are the barriers to your investment?Barriers on Investment: Cost, financial penalties, lack of available service providers, lack of skilled technicians, etc.

21Project Idea Note (PIN) PIN – Project sponsors / proponents submit potential projects for consideration to the CFU in the form of a Project Idea Note (PIN).
22Early Notification and Letter of Endorsement (LoE) LOE – If the PIN was submitted by a third-party project sponsor, and the CFU decides to develop it further, the Host Country (e.g the UNFCCC National Focal Point) will be notified of the project.
23Carbon Finance Document (CFD) CFD – CFU experts will investigate further and evaluate particular aspects of the project in discussions with the project proponent and prepare a CFD with the risk assessment.
24Letter of Intent LoILOI – The CFU formally signals its intention to purchase emission reductions generated by a specific project under terms agreed in return for the exclusive right to contract for the purchase of emission reductions.
25World Bank Due Diligence World Bank Due Diligence – All projects must comply with World Bank Group Operational Policies and Procedures, including those on environmental assessment. An Integrated Safeguard Policies review and Environmental Assessment (EA) is performed as a standard part of the appraisal of World Bank Group Projects.
26Baseline Study (BLS) and Monitoring Plan (MP) BLS and MP – Once the CFU has decided to include the project in the Portfolio, it will commission a Baseline Study and Monitoring Plan, if the project is not applying an approved methodology.
27Project Design Document (PDD) PDD – A project – specific document required under the CDM which will enable the Operational Entity (OE) to determine whether the project:(i) has been approved by the parties involved in a project,(ii) would result in reductions of greenhouse gas emissions that are additional,(iii) has an appropriate Baseline and Monitoring Plan. The PDD is prepared by the CFU and project sponsor.
28ValidationValidation – After the BLS, MP and PDD have been satisfactory developed, the CFU engages an Independent Validator (Designated Operational Entity, DOE) to validate them. This means that the Validator agrees that the ERs are additional to the baseline, the MP is sufficient, and that the ERs have a high chance of being certified under the Kyoto Protocol.
29RegistrationRegistration – The designated Operational Entity (DOE) contracted to undertake validation, upon the request of the CFU, submits the validation report and validation opinion to the Executive Board, along with a request for registration, together with the PDD, Baseline Study, MP, stakeholder consultation documentation and LoA, plus any other appropriate supporting documentation.
30Negotiation of Emission Reduction Purchase Agreement (ERPA) Negotiation of ERPA – After the consultations, the CFU legal team prepares a ‘term sheet’ and/or a draft ERPA for further discussion the project sponsor.
31Initial Verification / project commissioning Initial Verification / Project Commissioning – After the project’s construction and before its commissioning to produce ERs, the CFU contracts an Independent Third Party (a Verifier) for the project (different from the Validator). The Verifier will establish contact with the project and undertake an Initial Verification, which should confirm that the project is ready to generate verifiable and certifiable ERs. This will trigger the CFU acceptance of ERs from the project.
32MonitoringMonitoring – As part of project implementation, the project operator must implement the MP, which provides a methodology and a tool for measuring and calculating the emission reductions generated by the project. Once the project starts to generate emission reductions, the project entity monitors the project in accordance with the MP.
33Verification and Certification Verification and Certification–Verification and certification of the emission reductions will be undertaken periodically in accordance with the MP and other applicable guidelines by a DOE, who is contracted for the project by the CFU. The verifier will submit a verification report to the UNFCCC CDM Executive Board (EB) for a certification, which will confirm that the ERs have been achieved in the verification period in compliance with applicable CDM rules.
34Transfer of Certified Emission Reductions (CERs) Transfer of CERs – Once the ERs are certified, the CFU will pay for the amount of ERs as agreed in the ERPA and the ERs are transferred to Participants in accordance with the ERPA and / or Host Country Agreement and applicable UNFCCC or other rules.

44POWER SECTOR CARBON CREDIT PROJECT PROVISION OF LT CAPACITORS ON INDUSTRIAL AND AGRICULTURAL LOADS Among the various energy conservation measures, improvement of low power factor is an area where significant potential for saving exist. The power factor on the Industrial and Agricultural loads can be improved easily by the use of power factor equipment and is normally achieved by a suitable amount of capacitors load to compensate for the presence of inductive load in the system. Poor power factor on the system is also main cause of energy losses.To improve the low power factor on LT side PEPCO has envisaged a plan to install LT capacitors on Agricultural Tube well and small industrial connections as well having load up to 40KW.Total Number of Agriculture Tube well Connections in to DISCO’s :27875Load on Agricultural Tube well Connections in DISCO’s: 3511 MW.Total Number of Industrial Connections up to 40KW load in to DISCO’s:

49POWER SECTOR CARBON CREDIT PROJECT SF6 GAS LEAKAGE REDUCTION SF6 is a nonflammable, colorless, nontoxic, chemically very stable gas which is five times as heavy as air. At atmospheric pressure, its dielectric strength is 2.5 times higher than that of air.SF6 circuit breakers are installed in NTDC and DISCO’s (LESCO, FESCO, GEPCO, MEPCO, IESCO, PESCO, TESCO, HESCO, SEPCO & QESCO) Transmission Network.At present there are 12 NOs of 500 KV, 26 NOs of 220 KV, 508 NOs of 132 KV and 173 NOs of 66 KV & 33 KV Grid Stations catering Power to the System.PEPCO has introduced new technology and old oil and Air CB’s are being replaced with SF6-Gas Type. However during operations leakage is being experienced at different stations, this leakage needs to be reduced / minimized.

53POWER SECTOR CARBON CREDIT PROJECT REPLACEMENT OF ENERGY INEFFICIENT IRRIGATION TUBEWELL PUMPS/MOTORS WITH ENERGY EFFICIENT STANDARD PUMP/MOTORSOne million tube wells in the country heavy on power and fuel are known to be extremely inefficient in operations.Total number of agriculture tube wells installed in DISCO’s is with the load of 3511 MW, (Out of which the number of tube wells are with a sanctioned Load of 2908, 858 MW) while the remaining are diesel driven pumps.According to survey carried out by ENERCON and other consumer groups the efficiency of the present pumps is only 30% of the standard equipment. The pump sets are old centrifugal, turbine or submersible.Tube well Efficiency Improvement Program (TWEIP)USAID has initiated a Tube well Efficiency Improvement Program. A pilot program focusing within the jurisdiction of Multan Electric Power Company (MEPCO) to replace, 1000 old and inefficient agricultural tube well pumps sets (Pumps and Motors) with energy efficient tube well pump set has been commenced. USAID is Subsidizing 50% of the equipment cost for the farmers. The country wide program has a target a total number of 1000 tube wells in seven DISCO’s (MEPCO, FESCO, LESCO, GEPCO, IESCO, HESCO & PESCO).
54Energy SavingsPost replacement audits on 324 sites concluded that average pump set Energy Efficiency (%) has been enhanced from previous 37.45% to 54.85% and the average demand per pump set (Kw) reduced to Kw from Kw previously meaning there by 5.38 Kw savings per pump set replacement.On the basis of above Taking into account the total number of in-service/active Tube wells in the DISCO’s the Energy Savings to be generated from the replacement of old and inefficient agricultural tube well pump sets with energy efficient tube well pumps sets will be = x5.38Kw = 1181 MWEstimated Power Saving: 1181 MWAverage Operational Hours: 10 hours per day.

56POWER SECTOR CARBON CREDIT PROJECT PROVISION OF RMS/AMR, SMART METERING – AS A DSM ACTIVITY PEPCO Manages 10 DISCOS, (LESCO,FESCO, GEPCO, MEPCO, IESCO, PESCO,TESCO, HESCO, SEPCO & QESCO) More than million customers are served through primarily Electro Magnetic Meters and lately Digital meters have also been inducted. The Digital Meters have a proven record of reducing the line losses by eliminating theft of electricity. PEPCO intends to arrange for a remote system capable of measuring electricity consumption/ Customer usage besides generating all other information and data needed to run its specified Management information system (MIS) without the glitches inherent to the existing normal system. A major requirement of the system is to control the present level of administrative losses i.e. pilferage, theft and stealing of energy constricted installation of energy meters by-passing of the same and other such internal and external features. Introduction of Advanced Metering Infrastructure (AMI) fully incorporating RMS/AMR systems is expected to relieve the Distribution system of the present extravagant use / wastage. Consequently thereby it will significantly relieve the generation system.
57AMI and Its BenefitsAMI, in its essence, serves to move data and control signals between a consumer’s energy consumption and the DISCO that provides the electricity. The most basic level of AMI is called automated meter Reading (AMR). More sophisticated use of AMI involve two – way communication between the Distribution company and the smart Meter so data is transmitted in real time to the distribution company and tariffs and other control signals can be sent to the meter.Benefits:Customer service is improved through Remote Meter Reading and efficient data management. Power outages can be detected, identified and corrected more quickly for customers whose meters are connected to and work.Direct load Control: AMI allows for the energy flow to be set at a peak threshold on a per meter basis at specific times during the day. This allows the distribution company to do load shedding without having to completely switch off entire feeders as is currently the case. Peak usage is minimized. Consumers can benefit from lower electricity bill by using smart card controlled energy meters. Improve metering accuracy despite nonlinear loads.
