Only three days after the beginning of the nuclear catastrophe in Fukushima, Japan, on 11 March 2011, the German government ordered 8 of the country's 17 existing nuclear power plants (NPPs) to stop operating within a few days. In summer 2011 the govern--ment put forward a law -passed in parliament by a large majority -that calls for a com--plete nuclear phase--out by the end of 2022. These government actions were in contrast to its initial plans, laid out in fall 2010, to expand the lifetimes of the country's NPPs.The immediate closure of 8 NPPs and the plans for a complete nuclear phase--out within little more than a decade, raised concerns about Germany's ability to secure a stable supply of electricity. Some observers feared power supply shortages, increasing CO2--emissions and a need for Germany to become a net importer of electricity. Now -a little more than a year after the phase--out law entered into force -this paper ex--amines these concerns using a) recent statistical data on electricity production and de--mand in the first 15 months after the German government's immediate reaction to the Fukushima accident and b) reviews the most recent projections and scenarios by differ--ent stakeholders on how the German electricity system may develop until 2025, when NPPs will no longer be in operation.

“…Introducing price floors and caps as practiced by the Spanish model offers advantages in this respect, because price risks are limited for producers and society both (Ragwitz et al 2007;Klein et al 2010;Couture & Gagnon 2010). Generally, however, profit margins of plant operators are usually higher in premium schemes than under a feed-in tariff (Langniß et al 2009;Mitchell 2006). …”

“…The greater the exposure of producers to market risks in a particular scheme's design, the more pronounced the necessary increase in support costs will be. Moreover, compared to a FIT system, the risk of overcompensation is higher for market premium schemes, because total remuneration is more likely to diverge from actual project costs once electricity prices influence revenue (Langniß et al 2009;Mitchell 2006). Introducing price floors and caps as practiced by the Spanish model offers advantages in this respect, because price risks are limited for producers and society both (Ragwitz et al 2007;Klein et al 2010;Couture & Gagnon 2010).…”

Terms of use: Documents in UFZ Discussion Papers Department of Economics 4/2013 Promoting the Market and System Integration of Renewable Energies through Premium Schemes -A Case Study of the German Market PremiumErik Gawel, Alexandra Purkus January 20131 Promoting the Market and System Integration of Renewable Energies through Premium Schemes -A Case Study of the German Market PremiumErik Gawel 1 , Alexandra Purkus Abstract: With the share of renewable energies within the electricity sector rising, improving their market (i.e. inclusion in the allocative 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. 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.

Abstract:The integration of photovoltaic (PV) generators in the envelope of a building by means of building-integrated photovoltaics (BIPV) offers an immense potential, both in market development and the production of renewable electric energy that is close to the point of electricity consumption. In Germany, for example, by integrating photovoltaics in buildings up to 50% of the electricity demand can be covered. The political support of BIPV would contribute to the development and installation of BIPV components and therefore also promote the development of new business areas for industries dealing with components used in building envelopes and photovoltaic generators. BIPV can be separated into three different integration types: "technical", "formal" and "technical & formal". Political instruments for the support of PV-installations, particularly BIPV are discussed in this paper using Germany and France as examples. Due to successful financial support policies, PV became the most powerful electricity production technology in Germany. In France, the unique financial support of BIPV is resulting in an exemplary development and growth of certified BIPV components available on the market and, from a technical, aesthetic architectural and legal certainty point of view, facilitating the easy and widespread integration of photovoltaic generators in buildings.
