3. National Procedures for Annual Energy Reporting Oil : Data collected by Oil Division, DCMNR and used by SEI for Balance Legal basis : EUROPEAN COMMUNITIES (MINIMUM STOCKS OF PETROLEUM OILS) REGULATIONS, 1995. (SI No. 96/1995) Gas : Data collected from Bord Gais Eireann (BGE) Solid Fuel : Data collected from Bord Na Mona (for peat and briquettes) and from main solid fuel importers (for coal) Electricity : Data collected from Power Generators (Integrated Pollution Licences IPC) Renewables : Data collected from surveys carried out by SEI

4. Provisional Energy Balance 2002

5. 2000 Oil Balance

6. Sub-sectoral Breakdown

7. Timeliness and Quality of Data Timeliness Provisional balance – June Final balance – November Data Quality – problem areas Lack of legal basis for most of the data collection Subsector breakdown Biomass Private peat sod production Liberalisation and fragmentation of data sources

8. Emission Methods 1 Combustion Sources Tier 1 methods in general CO 2 emission estimates from operators of power plants (Tier 2) Tier 2 for domestic aviation (number of LTOs and estimated fuel use) Tier 3 for CH 4 and N 2 O from road transport (COPERT model)

9. Emission Methods 2 Fugitive Emissions gas company estimates of CH 4 from gas distribution (almost negligible due to new polyethylene pipe network) reports to OSPAR on emissions of CO 2 and CH 4 at sea from offshore gas production

10. Emission Factors Combustion Sources Country-specific emission factors for CO 2 for all fuels except petroleum coke and biomass default emission factors for CH 4 and N 2 O (IPCC or CORINAIR) Fugitive Emissions Country-specific emission factors for CO 2 and CH 4 (emissions reported directly to the inventory agency)

13. Lessons & Actions from Harmonisation Project Subsectoral disaggregation of the energy balance needs to be updated Differences in emission factors and calorific values used by EPA (Ireland) and Eurostat Methodological issues surrounding the treatments of petroleum coke, and CHP. Balance needs to be presented in a format that facilitates automatic entry into inventory

14. Priority Areas Sub-sectoral Energy breakdown National Energy Balance Presentation Format Calorific Values & Emission Factors Lack of Legal Basis for Energy Statistics Collection Assessment of Uncertainty
