Intelligent measuring system
An intelligent measuring system is a modern metering device that is connected to a communication unit (smart meter gateway).
The measuring data, e.g. electricity consumption, capacity or supplied energy, can be read remotely via the communication unit. You can view your measurement data via a local interface and personalized access so that you can use all information about your consumption or generation as required.
The data that has been read remotely is also made available to all relevant market partners. As your responsible meter operator and distribution system operator, we shall receive this data, as will your energy provider. Other authorised market partners may also receive the data.
In future, the intelligent measuring system will make it possible to control an installation via an controllable consumption unit in accordance with § 14a EnWG or a generation plant.
You can access your consumption data via a HAN interface (Home Area Network) of the smart meter gateway on site. We will be happy to provide you with the access data for the HAN.
Using the transparency and display software (TRuDI), you can track your billing-related consumption data on site via the communication unit at any time.
TRuDI offers a display function for the measured values available in the smart meter gateway. With the transparency function, you have the option of tracking your electricity supplier's tariff calculation locally based on the measured values and thus checking its invoice.
With TRuDI, the Bundesdisplay initiative provides a manufacturer-independent, standardized visualization solution that meets the requirements of the MsbG and the requirements of the Physikalisch-Technische Bundesanstalt (national metrology institute - PTB) and that can be used within the framework of the requirements of the Federal Office for Information Security (Bundesamt für Sicherheit in der Informationstechnik - BSI).
All information about TRuDI can be found on the PTB website:

The Smart Meter Operation Act (MsbG) prescribes so-called mandatory installation cases. The rollout time windows for the individual groups are staggered in time and depend on the technical availability of certified smart meter gateways. The technical availability was determined with the first so-called market declaration by the Federal Office for Security and Information Technology for the mandatory installation of final consumers with an annual electricity consumption between 6,000 kWh and 100,000 kWh. This market declaration has taken effect on February 24, 2020. A market declaration for generating plants and consumption facilities according to § 14a EnWG is currently not yet available.
|Mandatory installation cases||Market declaration occured?||Period exchange|
|Electricity consumption rate from 6,000 kWh up to 10,000 kWh per year||yes||within 8 years from 2020|
|Electricity consumption rate from 10,000 kWh up to 100,000 kWh per year||yes||within 8 years from 2020|
|Electricity consumption from 100,000 kWh per year||no||within 16 years from technical availability|
|Operation of a generation plant with an installed capacity of 7 kW to 100 kW||no||from technical availability within 8 years|
|Operation of a generation plant with an installed capacity from 100 kW||no||from technical availability within 8 years|
|Operation of a consumption unit in accordance with § 14a EnWG||no||from technical availability within 8 years|
An intelligent measuring system continuously registers electricity consumption and electrical output. The data is read remotely on a regular basis and is then stored. This information can be accessed via an online portal using a personalised access code.
Other metering devices, e.g. for gas or heat, can be integrated into the intelligent measuring system, with regular remote readings of all energy types creating even more transparency.
Having an intelligent measuring system enables you, in future, to take advantage of load-variable tariffs offered by an energy provider alongside the usual time-variable tariffs.
For intelligent measuring systems, the Measurement Point Operations Act (MsbG) bindingly sets out protection profiles and technical guidelines on guaranteeing data protection, data security and interoperability. This is intended to guarantee a uniform level of security which is extremely high.
The Federal Office for Information Security (BSI) is primarily responsible for the creation of these protection profiles and guidelines. Certified systems are those that carry the BSI seal. BSI is also responsible for the ongoing development of the protection profiles. We exclusively use certified intelligent measuring systems.
The technology for end consumers with an annual consumption between 6,000 kWh and 100,000 kWh is available with the first market declaration on February 24, 2020. A market declaration for the other installation cases is still pending. We will start installing the first intelligent measuring systems in the second half of 2020. The delivery of 500 devices is initially planned for this second half of the year. The number of intelligent measuring systems installed will increase continuously in the coming years. Legislators have provided that in the first three years after the rollout starts, ten percent of the corresponding customers, classified according to consumption groups, should be equipped with intelligent measuring systems. We will comply with this requirement.
We will inform you in good time by letter about the replacement of your meter and the appointment for replacing your current meter with a modern metering device.
