Renewable Energy Policy: Risk Hedging Is Taking Center Stage

The costs of renewable energy technologies have fallen sharply. Now the financing costs of new installations are playing an increasing role in the overall cost of Germany’s energy transition. This has put the primary focus of support instruments for renewable energy on creating more affordable financing conditions for investments. This report compares the effects of various policy instruments on risk ...

Market Incentives for System-Friendly Designs of Wind Turbines

Up until now, wind turbines have been designed to generate electricity at the lowest possible total cost, independent of this electricity’s market value. With an increasing penetration of wind power in the system, the market value of electricity generated by wind turbines is declining, since wind turbines tend to produce electricity at the same time. For this reason, it will be important in the future ...

Green New Deal nach Corona: Was wir aus der Finanzkrise lernen können

Bereits während der Finanzkrise in den Jahren 2008/2009 wurde diskutiert, ob klimapolitische Maßnahmen kurzfristig die Produktion und Nachfrage stimulieren und so auch Teil von Konjunkturpaketen sein können. Obwohl politische Entscheidungsträger in einer Krise dazu tendieren, auf bewährte Mittel zu setzen, wurden damals weltweit klimafreundliche Komponenten in die nationalen Konjunkturpakete integriert. ...

Private langfristige Stromabnahmeverträge (PPAs) für erneuerbare Energien: kein Ersatz für öffentliche Ausschreibungen

Der Ausbau von erneuerbaren Energien hat in Deutschland lange nur eine Richtung gekannt: steil nach oben. Jüngst ist er aber ins Stocken geraten, speziell der Wind-kraftausbau ist längst nicht mehr so dynamisch wie früher und nicht so, wie er sein sollte, damit Deutschland seine Ausbauziele für Erneuerbare und seine Klimaziele erreicht. In diesem Kontext werden Privat-abgesicherte PPAs (Power Purchase ...

A Green New Deal after Corona: What We Can Learn from the Financial Crisis

Already after the financial crisis in 2008/2009 there was a debate on whether elements aiming at sustainable development can be part of the stimulus packages and support the recovery of the economy. Despite the instinct of policy makers to prioritise battle-tested policies during a crisis, significant levels and different types of climate-friendly components were integrated in the 2009 stimulus packages ...

Way Off: The Effect of Minimum Distance Regulation on the Deployment of Wind Power

Several countries and regions have introduced mandatory minimum distances of wind turbines to nearby residential areas, in order to increase public acceptance of wind power. Germany’s largest federal state Bavaria introduced such separation distances of ten times the height of new wind turbines in 2014. Here, we provide a novel monthly district-level dataset of construction permits for wind turbines ...

Renewable Energy Policy in the Age of Falling Technology Costs

Cost of renewable energies have dropped, approaching wholesale power price levels. As a result, the role of renewable energy policy design is shifting – from covering incremental costs towards facilitating risk-hedging. An analytical model of the financing structure of renewable investment projects is developed to assess this effect und used to compare different policy design choices: contracts for ...

Too Good to Be True? How Time-Inconsistent Renewable Energy Policies Can Deter Investments

The transition towards low-carbon economies requires massive investments into renewable energies, which are commonly supported through regulatory frameworks. Yet, governments can have incentives - and the ability - to deviate from previously-announced support once those investments have been made, which can deter investments. We analyze a renewable energy regulation game, apply a model of time-inconsistency ...

Financing Power: Impacts of Energy Policies in Changing Regulatory Environments

Power systems with increasing shares of wind and solar power generation have higher capital and lower operational costs than traditional technologies. This increases the importance of the cost of finance for total system cost. We quantify how renewable policy design can influence cost of finance by addressing regulatory risk and facilitating hedging. We use interview data on wind power financing costs ...
