CAN Europe thanks the European Union’s Agency for the Coordination of Energy Regulators (ACER) for the opportunity to engage in preparatory discussions about the upcoming Scenario Guideline for the Ten Year Network Development Plans (TYNDPs). Following the series of Scenario Guideline workshops in July and August 2022, we summarise in this submission our proposals for key principles that would improve substantially the quality of the TYNDP scenarios if enshrined in the Scenario Guideline.

During the past decade, the scenario building process for the TYNDPs has been driven primarily by the European Networks of Transmission System Operators for Electricity (ENTSO-E) and for Gas (ENTSOG), following their legal mandate. In view of the introduction of the new Scenario Guideline, CAN Europe sees an important potential for improving the quality and credibility of the scenarios. The TYNDP scenarios can only live up to their role as the masterplan for Europe’s energy infrastructure if they help to prepare the ground for an accelerated energy transition. The scenario building must not prolong path dependencies on fossil fuels but spearhead the EU’s way towards the Paris Agreement’s objective of limiting average global temperature increase to 1.5°C.
