Ethernet data networks - a key success factor in the energy efficiency transition

Interview with
Ralf Klein, Managing Director HARTING Electronics

The necessity of (industrial) Ethernet networks for networking in the energy transition is of crucial significance. Only by consistently expanding data networks to each and every energy consumer will efficient and intelligent energy infrastructures be enabled. Ethernet, as a reliable and widely used technology for data transmission, plays a key role in integrating various energy sources and consumers into the power grid.

The energy transition is geared to shifting away from fossil fuels towards renewable energies. This means discontinuing the combustion of fossil fuels for transport purposes, but also refraining from their use in heating in the building sector and generating electricity from fossil fuels in power stations. This will lead to a change in energy sources and consequently to an increasing decentralisation of energy generation. Wind farms, solar power plants and other renewable sources are being built where they are strategically favourable and efficient, as is the production of alternative energy sources such as hydrogen. This is where networking enters the picture. Ethernet enables efficient communication and control between decentralised energy systems and the power grid.

Electricity generation

Networking allows renewable energy sources to be interconnected in order to share surplus energy and compensate for bottlenecks. This significantly improves the overall efficiency and reliability of the electricity grid. In addition, communication via Ethernet enables real-time monitoring and control of energy generation, allowing for optimum adaptation to current demand. Away from unnecessarily high, possible peak loads and towards the dynamic, demand-oriented production of energy according to current consumption.

Consumers

Ethernet also promotes the development of smart grids. By implementing intelligent technologies and communication systems, consumers will be able to manage their energy consumption more efficiently and distribute loads better. This will result in the better integration of electric vehicles, home storage systems and other energy-efficient technologies. The bottom line is that the major share of larger electrical consumers, both private and commercial, should become smart in future and be able to "coordinate" their consumption with energy suppliers.

In the industry

Networking is also crucial for the success of energy management systems in industrial companies. Ethernet-based solutions enable the comprehensive monitoring and analysis of energy consumption in real time, which in turn leads to better energy efficiency and lower costs. The energy requirement can be recorded and communicated very precisely, depending on the time of day and the ongoing production. By intelligently analysing the data over longer periods of time, algorithms can predict demand within a certain framework. This is particularly important in industry, which at 43% accounts for the largest single demand for electrical energy in Germany. If the transport sector becomes increasingly electrically powered in the future, this sector will also become very relevant for the precise coordination of demand and production.

In summary, it can be stated that Ethernet and networking play a central role in the energy transition, as they provide a common foundation for communication that enables the seamless integration and control of decentralised energy sources. By implementing intelligent technologies and smart grids, we will create sustainable and efficient energy infrastructures that are essential for a successful energy transition.
