Applications for
M2M SIM cards in the energy sector

Secure remote access

Remote Maintenance & Remote Control

Reliable mobile radio-based access, e.g. to photovoltaic and wind power plants - both for maintenance and troubleshooting from a distance - saves costs and on-site personnel deployment.

Wind farm control

Wind farm control & power retrieval

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.

Transmission of performance data - from anywhere

Smart metering: remote data reading and more

Permanent availability of consumption data for end consumers and energy suppliers thanks to automated remote reading. This allows you to identify potential energy savings and increase customer service and flexibility in the deployment of specialist personnel by eliminating meter reading appointments.

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 a commercial building, the street lighting in a pedestrian zone or a 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.
