Electricity markets and RES integration – Key challenges and possible solutions / Arthur Henriot &#38; Jean-Michel Glachant. European University Institute, March 2015, 55 p.

In this report we identify four key challenges for electricity market design in the context of RES integration. First, there is a need to ensure resources adequacy in the long-term. This challenge emerged as the profits of conventional generation assets have eroded under the pressure of intermittent RES with “zero” marginal costs. It is then not guaranteed that the assets being decommissioned will be replaced, especially as the deployment of RES is driven by uncertain support policies rather than market signals. Second, it is crucial that the flexible resources required to cope with RES variability are in place and incentivised to operate flexibly. Third, electricity market design must ensure efficient expansion of the transmission and distribution network, as significant investments are needed to connect intermittent RES. This challenge is made more difficult by the lack of coordination between network investments and generation investments, especially when the generation investments are driven by uncertain policies. Fourth, while the traditional organisation of power systems was based on a centralised operation of a set of large plants adjusting their production to follow load variations, system operation at the distribution level will be increasingly challenging with the development of distributed resources...Contents :1 Introduction: Intermittent RES features and market integration2 Challenges for electricity market design and RES integration towards 20303 Design elements to cope with these challenges
