Grid Resilience

Leading the Energy Transition

Enhancing grid reliability and network stability

To deliver electricity in the required quantity, quality, and reliability, the grid must be prepared with the right set of capabilities. Expanding, automating, and upgrading the transmission grid as well as ensuring grid stability are fundamental prerequisites for the success of the energy transition.


With our high-voltage products and systems, it is possible to transport renewable energy more reliably and with fewer losses to where it is needed: the world’s cities and hubs. On this basis, we are able to use various digital technologies to make grids work more efficiently – especially for large amounts of fluctuating energy and the ultra-short-term storage of renewable energy.


Digitalization gives us a higher transparency on the asset conditions and helps to predict or forecast the needs and the future behavior of the grid. With our Sensproducts technology we can react faster and take countermeasures earlier. With the launch of edge products we are making a technological breakthrough that will facilitate highly efficient transmission operation. All these technologies increase the reliability of grids by a higher degree of digitalization towards the Internet of Energy (IoE).

Grid stability

Production of intermittent renewable energy has risen significantly over the last decades. Therefore, new technologies are needed to keep HV power grids stable. Our Flexible AC transmission portfolio (FACTS) are designed to prevent high voltage fluctuations and power failures, to utilize network assets optimally, and to mitigate load-induced disturbances.

HVDC technology offers the most efficient means of transmitting large amount of power over long distances, help connect green offshore power to the grid, establish grid interconnections between countries and stabilize three-phase-grids. As a pioneer in HVDC technology, we provide  a comprehensive portfolio of efficient and sustainable solutions in all fields of application for HVDC technology.
