In the Netherlands the Authority for Consumers and Markets (ACM) regulates the grid operators in the electricity sector and the gas sector because they, by nature, are monopolists. As a Dutch grid operator in both sectors Enexis Netbeheer is subject to the tariff regulation of the ACM, which is aimed at stimulating efficiency and ensuring that the quality of the network is good. The tariff regulation applies to a regulatory period, and the current regulatory period stretches five years, from 2017 until 2021. The next regulatory period will cover 5 years as well and will be applicable from 2022 until 2026. The publication of the new method decision by the ACM was published on 20 September 2021.
