1. Network structure and security – an interplay of technology and strategy

The expansion of renewable energies has not destabilized the power grid in Germany – on the contrary. The increasing decentralization through photovoltaic and wind turbines ensures a more even distribution of feed-in and consumption. This increases reliability because individual failures can be compensated for locally more easily.

In addition, the so-called (n-1) principle plays a central role: the network is designed in such a way that even if a critical element – such as a line or a transformer – fails, the supply can continue without interruption. This high standard in network design makes the system particularly resilient to disruptions.

“The power supply will continue to be secure in the future if additional controllable capacities are built.” Klaus Müller, President of the Federal Network Agency.

2. Positive signals for investors, network operators and consumers

The current development has far-reaching effects – especially for investors in the areas of photovoltaics and storage technology. A stable grid offers a reliable basis for business models around renewable energies, especially if they can be integrated to benefit the grid.

Network operators also benefit: predictable network states, reduced susceptibility to failure and reduced effort in the event of a crisis improve operational efficiency. For end consumers, the high level of security of supply means more reliability and trust – a basic prerequisite for accepting the energy transition.

3. Challenges remain – but solutions are within reach

Despite the positive numbers, network transformation remains a challenge. The volatile feed-in from wind and solar requires flexibility, digital control and storage capacities. Particularly in the distribution networks, modernization and intelligent management are needed in order to maintain the network quality even with further expansion.

Technologies such as smart grids, real-time data analysis and controllable feeders are becoming increasingly important. The role of battery storage and controllable consumers such as heat pumps and electric vehicles is also increasing. They all help to smooth out load peaks and keep the network in balance.

4. Political framework: this is necessary now

The stability of the power grid is not only a technical achievement, but also the result of political decisions. Funding programs, investment incentives and clear guidelines for network operators have paved the way. Now it’s about developing this policy further: with a focus on digitalization, sector coupling and sustainable network expansion.

At the same time, politicians should focus on resilient structures – for example by promoting local energy projects, smart storage solutions and regionally coordinated network planning. The more complex the energy system becomes, the more important forward-looking coordination becomes.
