Abstract
This paper addresses the question of how renewable energies can contribute to security of supply. In order to analyse this subject, the paper has two differentiated parts. In the first part, the concept of security of supply is reviewed. This provides the baseline to understand how current electricity systems are planned, and how renewable energies fit in these systems. The
second part of the article assesses the actual contribution that variable renewable energies can make to security of supply, firstly from a qualitative point of view and secondly in measurable terms. The study is based on hourly 2013 data from offshore wind, onshore wind, wave and solar PV power production. The analysis is done over a year based on hourly values and based on a historical year.
Provided that the capacity credit is the amount of power variable renewables can reliably be
expected to produce at the times when demand for electricity is highest, the study focuses on
the capacity credit of future Danish scenarios including high penetrations of offshore wind,
onshore wind, wave and solar PV.
The results of this project can ultimately lead towards the improvement of existing rules and
methods in system planning and the development of integrated energy systems where the
electricity, heating and transport sectors are merged.
