  1. Efficiency and effectiveness of promotion systems for RES-E – An update on lessons learned from EU countries Reinhard Haas Vienna University of Technology

  2. SURVEY 1. Introduction 2. Historical developments 3. Success of strategies 4. Conclusions

  3. 1 INTRODUCTION: KEY REFLECTIONS

  4. INTRODUCTION CORE MOTIVATION: Policy targets for an INCREASE of RES-E! e.g. 2020/20/20/20 targets RES-E directive: increase share of RES-E from 12% 1997 to 22% in 2010)

  5. 2. HISTORY RES-E EU-27 2009:17% 1997:12%

  6. 2009: 7 % ELECTRICITY GENERATION FROM „NEW“ RENEWABLES IN EUROPE 1997: 1 %

  7. Total electricity and share of RES EU-27 * figures for 2009 and 2010 are preliminary!

  8. REMARK ON RES – DEPLOYMENT IN THE EU-COUNTRIES • Since about 1997 triggered by EU- directives and EU initiatives • Yet, specific country success stories very strongly related to national policies design!

  9. 3. SUCCESS OF STRATEGIES

  10. STATIC COST RESOURCE CURVES more expensive capacities (wind, PV) cheapest capacities (Co-firing biomass)

  11. HOW FEED-IN TARIFFSWORK EURO/kWh Costs PFix ? QOut kWh

  12. HOW QUOTA-BASED TRADABLE GREEN CERTIFICATES WORK Costs EURO/kWh PVar ? kWh QUOTA

  13. QUOTAS SWEDEN

  14. PRICES OF CERTIFICATES Continuous high level! Shortage in banked certificates!

  15. LEVEL OF FEED-IN TARIFFS

  16. SUPPORT LEVELS: COMPARISON TRADABLE CERTIFICATES FEED-IN TARIFFS

  17. Total costs for customers (PREMIUM) FEED-IN TARIFFS Total costs = EURO/kWh + Producer surplus Generationcosts C PFIT_C B PFIT_B PFIT_A A Cost curve Market price Target kWh

  21. IMPACT OF THE SHAPE OF THE COST CURVE Small Hydro [cent/kWh] Producer Surplus Biomass pure PZert Wind Costs Biomass cofiring Munic. waste Quota [GWh/year]

  22. THE SHAPE OF THE COST CURVE E U - 27 Producer surplus Additional generationcosts Electricity market price RequiredRES-Edeployment Total costs

  23. SUCCESS CRITERIA FOR STRATEGIES • Major objectives: • increase the amount of electricity from renewables and • reduce costs! Costs (EUR/ kW)(=efficiency) MW /Number of plants(=effectiveness)

  24. EFFECTIVENESS VS COSTS

  25. THE CASE OF SWEDEN Major characteristics: * since 2002: quota-based system of Tradable Certificates * also „old“ capacity allowed to fulfill quota * additional investment subs. for wind!

  26. IMPACT OF INVESTMENT SUBSIDIES Costs (Supply curve) [cent/kWh] Wind Loc. A Wind Loc. B Pcert_th Invest. Subsidiesfor wind Pcert_act Quota Biomass [GWh/year]

  27. PRICES OF CERTIFICATES IN SWEDEN

  28. 4. CONCLUSIONS (1) • There should be a clear focus on NEW capacities! IMPROVE/OPTIMIZE THE CURRENT SYSTEMS BEFORE HARMONISING OR IMPLEMENTING MAJOR CHANGES! • To ensure significant RES-E deployment in the long-term, it is essential to promote a broad portfolio of different technologies • A well-designed FIT provides RES-E-deployment fastest and at lowest costs; • Strategies with lower (financial) risk -> less profit requirements -> lower costs for society.

  29. 4. CONCLUSIONS (2) • Promoting RES in EU successful? Yes, but increase in energy consumption outweighed … • a dual system as in Spain in the long term is more expensive, and therefore it represents a higher burden for consumers, than a well designed single system. • Trading certificates in Sweden successful due to very specific favourable conditions (“Long”) • A European- wide trading system would lead to a much higher burden for European citizens than a comparable FIT for meeting the 2020/20%RES target!
