Power infrastructure resilience

Standing strong against any threat

Power supply reliability is more important than ever before – on all voltage levels, from the point of grid infeed all the way to the consumer.

Discover solutions from Siemens that help establish highly resilient power systems that immediately recover from disruptive events and adapt to impending threats and dangers. 

Identifying risks, increasing reliability

A holistic approach to power infrastructure resilience

The influencing factors on modern power systems are numerous, and they are constantly changing. That’s why it takes an integrated, intelligent, and comprehensive concept to protect today’s power systems. Such a concept needs to cover the entire power system on all voltage levels and to anticipate all possible risks. A main constituent of power system protection is to implement resilience. A more resilient power infrastructure has a higher ability to withstand disruptive events, reduce their impact, and speed up recovery.


Resilience with and despite digitalization

In the wake of digitalization, power systems have evolved from relatively self-contained, straightforward networks to complex intelligent infrastructures that are more prone to incidents of natural and human origin across multiple levels. 


Addressing the potential risks associated with this inescapable process as well as other developments, such as climate change, the rise of distributed power systems, and a sharp increase in cases of vandalism in some countries, necessitate that resilience be an integral part of all future power system operation, optimization, and planning.


“By failing to prepare, you are preparing to fail – especially in an increasingly complex energy system.”

Michael Weinhold, CTO of Siemens Energy Management


“When a storm comes, the oak will fall, but the reed will bend and quickly stand up again once the storm is over. We have to stop building oaks and start to build an energy system that is much more like reeds.”

Christoph Frei, Secretary General of the World Energy Council

Proactive, holistic power system protection

The resilience of a power infrastructure stands or falls with the weakest system component. It is crucial to identify all possible disruptive factors, anticipate incidents, and proactively secure the entire system. That’s why Siemens has developed a unique, holistic, three-dimensional approach.

Why action is needed

New challenges call for new strategies

Disruptive events in power supply infrastructures can never be completely ruled out. But a resilient power system is able to anticipate and absorb potentially disruptive events, adapt to them, and rapidly recover from an incident.


Safety concerns any power system as a whole

Power system operators have always taken extensive measures against system faults and system failures. But there are new threats that need to be addressed.


The vulnerability to cyber threats, for instance, is increasing in the wake of digitalization and with the growing number of interconnections. Extreme weather conditions due to climate change have quadrupled over the past 30 years and have become a severe threat to power systems in several parts of the world. The problem of vandalism is becoming steadily worse. The number of power outages caused by vandalism has reached alarming levels in several supply areas. In view of such new challenges, resilience is increasingly required to ensure a reliable supply of power. 

It’s a law of nature that you can’t avoid failures. The trick is to incorporate enough fault tolerance into a system and to make it learn from past failures to become even more stable. That’s the essence of resilience.

The many facets of resilience

Standing strong against any threat

The numerous aspects of power infrastructure resilience have one thing in common: They are based on the ability to anticipate, react, adapt, and recover quickly thanks to fast, targeted, and effective action on the physical as well as on the digital and the systemic side.
