Cost-efficient and sustainable deployment of renewable energy sources towards the EU 20% target by 2020, and beyond (RES4LESS)

The project aims to develop a roadmap to a cost effective deployment of RES in the period up to 2020 and 2030. In the project we will both analyze the time frames 2010 to 2020, and 2020 to 2030 respectively. The latter time frame is important as post 2020 targets and ambitions are to be expected and also in terms of focusing on the longer term aspects and to analyze possible lock-in situations. The roadmap will identify a potential RES development pathway, including the required cross-border cooperation mechanisms, and the potential cost/benefits that arise from cross-border cooperation in comparison to a more national, fragmented approach to achieving national RES targets. In order to design the Roadmap, the project will identify surplus potentials of RES, in particular wind energy, biomass and solar energy in EU27+. We will start with a preliminary estimate of the RES surpluses using the information from the National Renewable Action Plans (NREAPs) of the individual Member States.


  • Identification and quantification of the surplus potential/Valleys of Opportunity of renewable energy sources. Practical analysis of cooperation mechanisms to exploit surplus RES potentials /Valleys of Opportunity in EU27+ through concrete case studies.
  • Analysis and categorization of cooperation mechanisms to speed up the deployment of RES. A comparison of the benefits of coordinated and cooperative approach to achieving national RES targets compared to a national and fragmented approach.
  • Roadmap to successfully implement cooperation mechanisms allowing for a more cost-efficient development pathway.
  • Strong involvement and dialogue with stakeholder and policy makers.
  • Effective communication and dissemination of results.

Lessons learned

  • In order to maximize the chance of realizing cost savings through cooperation mechanisms it is very important to engage in early negotiations;
  • While the impact of risks and uncertainties can be reduced by starting with small size cooperation agreements, the maximum economic benefits can be achieved by ensuring the possibility to scale-up in case the right conditions are met;
  • Uncertainty can be reduced by performing feasibility studies and sensitivity analyses at an early stage.
