ACER’s amendment proposals for the European Grid Codes
This document offers a brief overview for those who may not be familiar with the role of electric vehicles (EVs) in Europe’s electricity grids, specifically highlighting the requirements for generators (RfG) as part of ACER’s proposal. With the rising number of EVs, challenges such as load peaks and grid instability arise, but they also present opportunities for better management of renewable energy. European lawmakers have assigned the Agency for the Cooperation of Energy Regulators (ACER) the task of revising the Grid Codes to create standardized connection requirements for EVs and electric vehicle supply equipment (EVSE). The proposed modifications aim to improve grid stability and facilitate vehicle-to-grid (V2G) systems, which can provide crucial services like frequency regulation. If these updates receive approval, they are anticipated to be implemented by the end of the decade.
