Under the ICER platform, energy regulators cooperate within ICER through virtual Working Groups (WGs).
From 2009-2015, ICER was structured along four Working Groups: Security of Supply, Climate Change, Competition and Affordability, and Good Regulatory Practices. For the 2015-2018 period, the Working Groups were refocused on the roles and challenges that regulators face in evolving market situations, as follows: Electricity (VWG1), Gas and Other Fuels (VWG2), and Technology and Innovation (VWG3). As of August 2023, VWG1 and VWG2 have concluded.
