Applications for
M2M SIM cards in the energy sector

Remote Maintenance & Remote Control

Secure remote access
Reliable cellular network-based access, e.g. to photovoltaic and wind power plants - both for maintenance and troubleshooting remotely - saves costs and on-site personnel deployment.

Wind farm control & power retrieval

Wind farm control
Secure and virtually fail-safe transmission of performance data such as for power generation by regenerative energies for project planners, energy suppliers and power producers.

Smart metering: remote data reading and more

Transmission of performance data - from anywhere
Permanent availability of consumption data for end users and energy suppliers thanks to automated remote reading. This allows you to identify potential energy savings and, by eliminating meter reading appointments, increase customer service as well as flexibility in the deployment of specialist personnel.

Monitoring of open space PV

Monitoring of open space PV
Regardless of where a solar park is installed: With our M2M SIM card, plants can be monitored from anywhere. Mobile radio-based data transmission not only provides better protection against outages, but is also cheaper than transmission by cable, depending on the location.

Transmission of performance data - from anywhere

Transmission of performance data - from anywhere
Whether from the smart heating system in the commercial building, the street lighting in the pedestrian zone or the wind farm in the middle of nowhere: With our M2M SIM in your telematics units, sensors and routers, you receive data from your systems worldwide in near real time.

Smart Grid: Intelligent Electricity Networks

Smart Grid: Intelligent Electricity Networks
Cellular network-based transmission of data to utilities on energy production and consumption. For decentralized management of energy flows and for timely control of power fluctuations and avoidance of unstable grid conditions.

M2M SIM cards for smart energy solutions

For the efficient control of energy: Whether you are a municipal energy supplier, electricity producer or PV project developer - with our M2M and IoT SIM card, we offer you access to the strongest mobile network on site at every location. In this way, generation and consumption data is transmitted automatically, reliably and securely at all times.

Modern energy management requires the consistent and reliable use of data. With our M2M solution, we enable your end devices to transmit data via mobile communications so that you have all the relevant data at your fingertips. Whether for controlling the energy production of an offshore wind farm or for remote reading of smart meters. You benefit from flexible M2M rates and maximum network availability.
