DAC PROJECT Capacity Building in Balcan Countries for the Abatement of Greenhouse Gases Setting priorities for GHG emissions reduction George Mavrotas NATIONAL TECHNICAL UNIVERSITY OF ATHENS Tirana –
DAC Project / Tirana, Structure of the presentation Analysis of the current situation – Recognize priorities Indicative measures and policies Evaluation of the measures Priorities according to local experts Concluding remarks
DAC Project / Tirana, Contribution of Greenhouse Gases in the EU
DAC Project / Tirana, Focus: Energy sector CO 2 emissions from the energy sector
DAC Project / Tirana, Power generation characteristics Installed capacity 1446 MW hydro power 35 MW thermal power Production 99% from hydro power (normal year: 4300 GWh) Recognized problems High T&D losses (~25%) Strong dependence on hydrological conditions
DAC Project / Tirana, Measures and Policies for Electricity Generation The future Further exploitation of hydro potential (now only 35%) It is unavoidable to cover the increased electricity demand by thermal power plants (TPP) in order to enhance the security of supply (diversification of power supply mix) Forecasted capacity of TPP till 2020 ~850 MW Share of TPP production ~40% in 2020 High Priority Reduce T&D losses Clean and efficient technologies for TPP units Natural gas > Oil > Coal
DAC Project / Tirana, Measures and Policies for the Demand Sectors The aim should be 3-fold: To increase energy efficiency through minimisation of energy losses To upgrade existing infrastructure with new appliances/equipment To introduce cleaner fuels and renewables
DAC Project / Tirana, Measures and Policies for the Residential & Tertiary Sector Reduction of thermal losses in existing buildings (insulation + double glazing) Updating building specifications for new buildings Buildings shading Use of low energy lamps Use of efficient domestic appliances Solar water heating systems Penetration of natural gas District heating CHP in large buildings (hotels, hospitals, etc)
DAC Project / Tirana, Measures and Policies for the Industrial Sector Improved maintenance of energy equipment Energy conservation (reduction of losses) Substitution of solids and oil with natural gas Cogeneration with natural gas Exploitation of biomass (agricultural residues)
DAC Project / Tirana, Measures and Policies for the Transport Sector Improved maintenance of private cars, trucks and buses Improvement of road network Improvement in traffic lighting Promotion of public transport Increased natural gas in public transport
DAC Project / Tirana, Evaluation of measures Cost estimation Cost per ton of CO 2 saved (specific cost) Contribution to CO 2 emissions abatement Marginal abatement cost curve Additional criteria Ease of implementation (missing infrastructures, administrative-legislative barriers) Environmental synergies Impact on employment and regional development
DAC Project / Tirana, Cost per ton of CO 2 saved Comparison with the relative baseline scenario option Specify the reference unit (e.g. 1 household) and the reference time period (e.g. 1 year) Cost and CO 2 emissions estimation for the baseline scenario option (without the measure) Cost and CO 2 emissions estimation with the measure implementation
DAC Project / Tirana, CO 2 abatement estimation Specify the target year Assume a penetration rate of the measure at target year Estimate the CO 2 abatement at target year: CO2ab=(CO2 b -CO2 m ) ref_unit units targ_year penetration_rate
DAC Project / Tirana, Evaluation of the measures: The case of Albania Quantification of 26 measures in the energy sector Residential sector: 9 Services:3 Industry:5 Transport:1 Agricultural:1 Energy Transformation:7
DAC Project / Tirana, Ranking according to the specific cost of measures
DAC Project / Tirana, Ranking according to the CO 2 abatement in 2020
DAC Project / Tirana, Marginal abatement cost curve for 2020
DAC Project / Tirana, Comments Almost all the studied measures are beneficial even from a financial point of view Mostly energy conservation measures and some fuel- switch In 2020 the potential of CO 2 emissions abatement is about 7 Mt. It can be attained with measures that are also economical acceptable.
DAC Project / Tirana, Example: Economy lamps Baseline scenario: Incandescent lamps Base of calculations: 1 typical household (100 m 2 ) Reference time period: 1 year Incandescent lamps Economy lamps Lighting power350 W63 W Annual consumption (2.5h/day)315 kWh57 kWh Price of 1 lamp (100W 18W) Lifetime~ 1 year~ 8 years
DAC Project / Tirana, Example: Economy lamps (2) Annualized cost per lamp: Incandescent: 1.1 Economy lamp:CRF(5%, 8 years) 18.9 = = 2.93 Annualized cost per household: Incandescent:5 lamps/household 1.1 /lamp = 5.5 Economy lamps: 5 lamps/household 2.93 /lamp = 14.7 Annual electricity cost (~ /kWh): Incandescent:0.098 /kWh 315 kWh = 30.9 Economy lamps: /kWh 57 kWh = 5.6
DAC Project / Tirana, Example: Economy lamps (3) Total annual cost per household: Incandescent: = 36.4 Economy lamps: = 20.3 Power generation data Transmission losses: 15% Average emission factor (2020): kg CO 2 /kWh Power generation CO 2 emissions per household Incandescent: /( ) = 97 kg CO 2 Economy lamps: /( ) = 18 kg CO 2
DAC Project / Tirana, Example: Economy lamps (4) Abatement cost: (20.3 – 36.4) / (97 kgCO 2 – 18 kgCO 2 ) = -204 / tCO 2 Number of households in 2020: ~ 1,440,000 Penetration of the measure until 2020: ~ 50% CO 2 abatement in 2020: 1,440,000 (97 kgCO 2 – 18 kgCO 2 ) 0.5 = 56.9 kt CO 2
