Integration Costs of Wind and Solar Photovoltaics

Structuring the debate around the costs of integrating wind and solar photovoltaics into power systems

  • Project Duration: 12/2014 - 06/2015

Wind and solar power are increasingly shaping and transforming power systems in Europe and worldwide. The generation costs of these technologies (as captured e.g. by the LCOE) have experienced a strong decrease over the last few years. Nevertheless, given their unique features (variable and uncertain output, location-specific), wind and solar energy bring specific economic challenges when integrated into power systems. These challenges encompass the so-called “integration costs”, which cover the impact of renewable energies on grids development, balancing and changes in the utilization of the conventional generation fleet. The definition and the range of these impacts are subject to controversy amongst academics and policy advisers. This project, launched together with the French institute IDDRI, aims at better understanding the diverse assessments on this issue amongst experts both in France and in Germany. Its goal is to initiate a constructive dialogue process, to help developing a common understanding of the different perspectives on integration costs and to discuss the effects of potential political choices.
