The aim of this project is to inform the successful implementation of theNational Climate Change Strategy. This will be realised by increasing knowledge and addressing key information gaps surrounding the interactions between energy policies and the NCCS measures relating to the electricity supply sector.

Study on the Economic Analysis of RE Support Mechanisms in the Electricity Generation Sector , a research project funded by Sustainable Energy Ireland under its Renewable Energy Research, Development and Demonstration Programme. The study is co-ordinated by the Energy Economics Group in Vienna University of Technology and the other project partners are Ecofys and Distributed Energy Compnay. It provides a detailed technical, economic, financial and regulatoy analysis of the various market based renewable energy support mechanisms the may be employed to meet Irish RE targets going forward. See Final Report
