RAP has developed and presented to regulators, member states and stakeholders an overview of the key elements of European electricity market integration in Europe and how decisions in the various areas of integration may act either to advance–or interfere with–Europe’s power sector decarbonisation agenda. RAP Principal Meg Gottstein and co-author Philip Baker from University of Exeter have provided briefings and Q&A forums on these issues in Brussels, in coordination with the European Climate Foundation. This is the Advisory Note prepared by RAP on the consultation issued for comment by the Agency for the Cooperation of Energy Regulators (ACER) on one aspect of the market integration rules: the draft Framework Guidelines for Grid Connection.
