DIW Discussion Papers 1495 / 2015
In Germany and beyond, various capacity mechanisms are currently being discussed with a view to improving the security of electricity supply. One of these mechanisms is a strategic reserve that retains generation capacity for use in times of critical supply shortage. We argue that strategic reserves have specific advantages compared to other capacity mechanisms in the context of the European energy ...

DIW Discussion Papers 1494 / 2015
Abstract EU power market design has been focused on facilitating trading between countries and for this has defined interfaces for market participants and TSOs between countries. The operation of power systems and markets within countries was not the focus of these developments. This may have contributed to difficulties of defining or implementing a common perspective in particular on intraday and ...

Germany changed renewable remuneration for wind power from a fixed Feed-In Tariff (FIT) to a floating Market Premium Scheme (MPS) in 2012. One aim of this adjustment was to better align the supply of generated wind electricity with the demand for it, e.g. through more system-friendly wind turbine technology choices. In energy systems with a high share of variable renewable energies, such turbines produce ...

We examine under which conditions a cap-and-trade mechanism can deliver a dynamically efficient abatement pathway and contribute to a robust investment framework. For this we develop a numerical dynamic partial-equilibrium model that includes differentiated objective functions of different market participants for holding emission allowances based on their banking strategy. If the surplus of allowances ...

DIW Discussion Papers 1456 / 2015
We revisit key elements of European power market design with respect to both short term operation and longer-term investment and re-investment choices. For short term markets, the European policy debate focuses on the definition of common interfaces, like for example gate closure time. We argue that that this is insufficient if the market design is to accommodate for the different needs of renewable ...

DIW Discussion Papers 1441 / 2015
The financing of infrastructures is a major topic in recent energy policy debates. Project finance, as a specialized form of debt finance, thereby has become a well-established financing tool. This paper contributes a qualitative and quantitative analysis of the determinants of the debt ratio in project finance, using data on 26 liquefied natural gas (LNG) export and import projects. We argue that ...

A shift from zonal pricing to smaller zones and nodal pricing improves efficiency and security of system operation. Resulting price changes do however also shift profits and surplus between and across generation and load. As individual actorscan lose, they might oppose any reform. We explore how free allocation of financial transmission rights to generation and load can be used to mitigate the distributional ...

DIW Discussion Papers 1387 / 2014
The 2014 reform of the German Renewable Energy Act introduces a mandatory shift from a fixed feed-in tariff to a floating premium system. This is envisaged to create additional incentives for project developers, but also impacts revenues and costs for new investments in wind generation. Thus uncertainties for example about balancing costs and the impact of the location specific generation profile on ...

This paper analyzes the trade-offs for using feed-in tariffs or tenders to remunerate different scales of solar photovoltaics (PV) projects. In recent years, European countries increasingly combined feed-in tariffs for small renewables systems with tenders for large installations. This study develops an analytic framework to quantify deployment effectiveness of responsive feed-in tariff adjustment ...

DIW Discussion Papers 1271 / 2013
In the European Emissions Trading System, power generators hold CO2 allowances to hedge for future power sales. First, we model their aggregate hedging demand in response to changes in expectations of future fuel, carbon and power prices from forward prices. This partial equilibrium analysis is then integrated into a two period model of the supply and demand of CO2 allowances considering also emissions ...
