Act of 23 March 2007 on the Supply of Electricity and Electricity Supply Ordinance of 14 March 2008

Article 17a ESA - Smart metering systems
1 A smart metering system installed on the premises of the end-consumer, producer or stockholder is a metering device which records electricity, allows two-way data transmission and records actual electricity flow and real-time fluctuations.
2 The Federal Council may issue requirements concerning the introduction of such smart metering systems. In this regard, it shall take account of the international standards and the recommendations of the recognised specialist organisations. It may in particular require grid operators to proceed to fit smart metering systems until a given date on the premises of all end-consumers, producers and stockholders or certain categories of these.
3 Having regard to the federal legislation on metrology, the Federal Council may set minimum technical requirements which smart metering systems shall meet and other characteristics and additional equipment and functions which they shall include, especially in relation:
a. to the transmission of metered data;
b. to the support of tariff systems;
c. to the support of other services and applications.

Article 8 ESO - Metering system and information processes
1 The grid operators shall be answerable for the metering system and information processes.
2. For this purpose, they shall establish clear and non-discriminatory directives governing, in particular, the obligations of the businesses concerned and the schedule and form of data for communication. Such directives shall allow third parties the option of participating in the provision of services, with the grid operator’s consent, in the context of the metering and information system.
3 Within an agreed time limit, and in a uniform and non-discriminatory way, the grid operators shall provide the businesses concerned with the measurements and information necessary:
a. to operate the grid;
b. to manage the balance;
c. to supply electricity;
d. to allocate the costs;
e. to calculate remuneration for grid utilisation;
f. to run the billing processes under EnA and the Energy Ordinance of 1 November 2017 (EnO);
g. to engage in direct marketing; and
h. to use smart order and regulation systems.
3bis They shall not bill buyers for services under paragraph 3 over and above the grid usage charge. If the services referred to in paragraph 3 are provided by third parties, the grid operators shall compensate them fairly.
4 On request, and against compensation covering the costs, the grid operators shall provide additional data and information to the persons responsible for balance groups and other businesses concerned, with the agreement of the end-consumers or generators concerned. All figures recorded in the preceding five years shall be supplied.
