The Council of European Energy Regulators (CEER), Energy Community Regulatory Board (ECRB) and the Association of Mediterranean Energy Regulators (MEDREG) are organising their 3rd Trilateral CEER-ECRB-MEDREG Workshop on Regulatory means to foster active customer engagement – Flexibility, demand response, prosumers. Consumer protection is a core pillar of CEER, ECRB and MEDREG activities and a central target of regulatory work. This year’s trilateral event will discuss regulatory means to foster active customer engagement and the impact of Covid-19 on the end consumers. Special focus will be out on flexibility, demand response, prosumers. The workshop will be the occasion to present different case studies and trends in the region of activity of the three associations. The meeting will be organised in an online format.
