In preparation for a smart meter roll-out in the Netherlands the involved parties (including grid operators) set up standard specifications for the smart meter, the so called Dutch Smart Meter Requirements (DSMR).
During the handling of Smart Meter legislation by the Dutch parliament some questions and concerns were raised regarding security & privacy and the functionalities of the smart meter. The latter concerned the possibilities to connect external units such as displays or energy management system via the so called consumer interface (P1 port) and measuring the gross local generation.
The Association of Dutch Network operators - "Netbeheer Nederland" - created a taskforce that carefully investigated the (latent) wishes of all stakeholders regarding the functionalities of the smart metering infrastructure. This resulted into a roadmap consisting of five phases.
