  1. Dutch Protocol Monitoring Energy Savings & EU-directiveP. BoonekampECN, NetherlandsEU/ECEEE-seminar21-9-2004, Brussels

  2. Key features protocol • Top-down approach • Savings for 6 sectors and national • Format coupled to policy issues • Primary energy units • Uncertainty margins in saving results • Lessons for monitoring of Directive

  3. Protocol method (1): saving categories • Saving categories: • A. End use of heat and electricity • B. Conversion end-users (co-generation) • C. Conversion E-sector (power stations) • All energy use figures in primary units of the base year (static primary)

  4. Protocol method (2): calculation • A. End use: • Saving on end use = Reference use – actual use (fuel/heat or electricity) • Reference use = base year use * change in energy relevant variable (ERG) • B. Co-generation: • Savings = difference with separate production of heat/electricity • C. Power stations: • Savings = effect higher conversion efficiency per type of fuel

  5. Protocol method (3): end use Savings Change energy use

  6. Primary energy units? (1)

  7. Primary energy units? (2)

  8. Quality of saving figures • Quality dependent on: • Margins in energy consumption data • Margins in data on ERG-variable • Appropriateness of ERG for determining energy-use-without-savings (des-aggregation, choice of ERG) • Length of period of observation • Quality saving figure: x% +/- y%-point

  9. Uncertainty margins total saving (1990 - ….)

  10. Quality Dutch saving results • National 1990-2000: 1,2% +/- 0,3% • National 1995-2002: 1,0% +/- 0,3% (0,7% final + 0,2% co-gen. + 0,1% power) • Sectoral end use: industry good, services bad, remainder fair • Conversion end use: good • Conversion E-sector: fair/good

  11. Lessons for monitoring of directive • Uniform approach for EU > protocol, top-down, indicators • Consistent approach for end use, co-generation and supply > primary energy units • Uncertainty crucial for use of results: bad input data > big margins > conclusions after 3-10 years only • Policy related fraction of total efficiency > alsobottom-uppolicy measure evaluations • Co-generation end users > both directives integrated? • Service sector > very weak results! • Transport/households > discussion on definition efficiency??

  12. Dual monitoring approach • Protocol/indicator approach: • Total efficiency increase (per sector) • Consistent with national efficiency result • Sufficient quality for policy evaluation • Policy measure evaluation: • Policy related savings (per measure) • Contribution of EU- and MS-policy • Integration/check: • Policy related savings < total savings • Comparison of effects common measures
