The Influence of Policy Regime Risks on Investments in Innovative Energy Technology

Ernesto Garnier and Reinhard Madlener

Abstract:
This paper dissects the ways in which policy regime risks influence decisions over innovative energy technology investments. We apply compound real options methodology to evaluate the investment in a virtual power plant platform and distributed energy resource (DER) assets in view of volatile electricity market prices and an uncertain future electricity market design. The analysis reveals two aspects of policy regime risks: a policy content effect relating to actual market dynamics resulting from a (new) policy regime, and a policy process effect relating to (uncertainty about) the speed and probability of a regime change. The paper underlines the importance of predictable policymaking to stimulate risky investment. It further details the need to account for technology-specific investment responses to different policy regimes and risks, caused by different degrees of market versus subsidy exposure and differences between platform versus non-platform technologies.



Regulatory Options for Local Reserve Energy Markets: Implications for Prosumers, Utilities, and other Stakeholders

Christiane Rosen and Reinhard Madlener

Year: 2016
Volume: Volume 37
Number: Bollino-Madlener Special Issue

Abstract:
While the share of fluctuating renewable energy resources is constantly increasing, the centralized, hierarchical organization of the current energy system and markets cannot adequately accommodate such decentralized electricity generation. New ideas have been developed and discussed for improved integration, also in Germany, one of the lead markets. Examples in this context are virtual power plants and microgrids. This paper presents a new local reserve energy market design (applied to residential households), which can facilitate the operation and allow trading within these constructs. Emphasis is put on the regulatory options and current market framework, mainly from a European and a German perspective, which serve as a basis for implementing the local market. It can be shown that using existing regulatory structures, a local market with simple rules (comparable to an "energy-eBay") can be easily installed.



Auction Schemes, Bidding Strategies and the Cost-Optimal Level of Promoting Renewable Electricity in Germany

Andreas Voss and Reinhard Madlener

Abstract:
Germany is among the leading countries regarding the promotion of renewable energy towards a sustainable energy system transition. In this paper, we investigate the German pilot auction scheme for solar photovoltaics introduced in the Renewable Energies Act 2014 (EEG 2014) that serves as a pilot for the auction-based promotion of the three major large-scale renewable electricity generation technologies (wind, solar, biomass) as of 2017. A strategic bidding model is used to determine the optimal bidding strategy and to determine the resulting project value. We consider pay-as-bid and uniform pricing and single and multiple bids. Moreover, we investigate the impact of investment cost uncertainty. In a sensitivity analysis we show how bid strategy adjustments affect the outcome. Specifically, higher uncertainty regarding the market clearing price increases the project value, as this additional uncertainty can be used to raise the probability of obtaining a higher level of remuneration by an adjusted auction strategy. The first-price auction can generate additional profits by placing a second, higher bid with a low probability of success. Investment cost uncertainty can have either a positive or negative impact on the project value, depending on the auction parameter values chosen.
