Carbon Lock-Out: Advancing Renewable Energy Policy in Europe

et al. 2012

As part of its climate strategy, the EU aims at increasing the share of electricity from renewable energy sources (RES-E) in overall electricity generation. Attaining this target poses a considerable challenge as the electricity sector is "locked" into a carbon-intensive system, which hampers the adoption of RES-E technologies. Electricity generation, transmission and distribution grids as well as storage and demand response are subject to important path dependences, which put existing, non-renewable energy sources at an advantage. This paper examines how an EU framework for RES-E support policies should be designed to facilitate a carbon lock-out. For this purpose, we specify the major technological, economic and institutional barriers to RES-E. For each of the barriers, a policy review is carried out which assesses the performance of existing policy instruments and identifies needs for reform. The review reveals several shortcomings: while policies targeting generation are widely in place, measures to address barriers associated with OPEN ACCESSEnergies 2012, 5 324 electricity grids, storage and demand are still in their infancy and have to be extended. Moreover, the implementation of policies has been fragmented across EU Member States. In this respect, national policies should be embedded into an integrated EU-wide planning of the RES-E system with overarching energy scenarios and partially harmonized policy rules.

“…With the rising share of RES in the energy mix, an increase in regional grid congestions and voltage fluctuations can already be observed, necessitating short-notice interventions by Transmission System Operators (TSOs) (which are legally based on sec 11 EEG and sec 13 (2) EnWG; c.f. Brandstätt et al 2011;Borggrefe & Nüßler 2009;TenneT 2012;50Hertz 2012). Moreover, particularly in the case of wind power, the coincidence of high production levels with low demand can cause negative price spikes at the electricity exchange, which can involve significant economic costs (Brandstätt et al 2011;Andor et al 2010;Nicolosi 2010).…”

“…Several factors are relevant in explaining the rising number of interventions, such as the growing share of intermittent RES in total electricity production and the increasing regional divergence of electricity supply and demand (cf. Borggrefe & Nüßler 2009). An estimation of the influence of individual factors and potentially positive effects of the premium scheme on grid stability is beyond the scope of this paper.…”

To transform the energy system efficiently while ensuring security of supply, it is necessary to increase the alignment of renewable electricity production with short-and long-term market signals. By offering plant operators a premium on top of the electricity market price, premium schemes represent a potential option for achieving this, and have been implemented by several EU member states. This paper focuses on the case study of the German market premium scheme, which has been adopted as part of the 2012 amendment of the Renewable Energy Sources Act. Building on an evaluation of early experiences, we discuss whether the market premium in its current design improves market and/or system integration, and if it seems suitable in principle to contribute to these aims (effectiveness). Also, potential efficiency gains and additional costs of "administering integration" are discussed (efficiency). While market integration in a narrow sense (i.e. exposing renewables to price risks) is not the purpose of the German premium scheme, it has successfully increased participation in direct marketing. However, windfall profits are high, and the benefits of gradually leading plant operators towards the market are questionable. Incentives for demand-oriented electricity production are established, but they prove insufficient particularly in the case of intermittent renewable energy sources. It seems therefore unlikely that the German market premium scheme in its current form can significantly improve the market and system integration of renewable energies. To conclude, we provide an outlook on alternative designs of premium schemes, and discuss whether they seem better suited for addressing the challenges ahead.

V. m. § 13 Abs. 2 EnWG; dazu Brandstätt et al 2011;Borggrefe u. Nüßler 2009;TenneT 2012;50Hertz 2012). Zudem kann eine hohe Windeinspeisung in Zeiten niedriger Nachfrage zu negativen Preisspitzen an der Strombörse führen, welche mit signifikanten volkswirtschaftlichen Zusatzkosten einhergehen können (Brandstätt et al 2011;Andor et al 2010;Nicolosi 2010).…”

Terms of use: Documents in AbstractWith the share of renewable energies within the electricty sector rising, improving their market integration (i. e. inclusion in the steering and remuneration processes of the electricity market) and system integration (i. e. enhanced responsibility for grid stability) is of increasing importance. To transform the energy system efficiently while ensuring security of supply, it is necessary to increase the alignment of renewable electricity production with short-and long-term market signals. The German Renewable Energy Sources Act 2012 introduced the market premium to provide market experience to renewable plant operators and incentives for demand-oriented electricity production. Half a year after its introduction, the instrument is already being criticised as ineffective and expensive. Building on early experiences, this article examines whether the market premium in its current design improves market and/or system integration, and if it seems suitable in principle to contribute to these aims (effectiveness). Also, potential efficiency gains and additional costs of "administering integration" are discussed (efficiency). While market integration in a strict sense (i. e. exposing renewables to price risks) is not the purpose of the market premium, it has successfully increased participation in direct marketing. However, additional costs and windfall profits are high, and the benefits of gradually leading plant operators towards the market are questionable. Incentives for demand-oriented electricity production are established, but they prove insufficient particularly in the case of intermittent renewable energy sources. A continuation of the instrument in its current form therefore does not seem recommendable. To conclude, potential alternative solutions are presented.
