Grid resilience

Our  Pretact® concept maximizes the resilience of modern power grids. It comprises a comprehensive set of modular features to prevent and protect transformers and high-voltage products better from operational issues as well as against natural disasters or forced outages.

The world’s first explosion- and fire safe substation concept Pretact EcoSafeT™.  It sets new standards in environment, health and safety to achieve a reliable fire- and explosion safe solution for the entire substation and all its products.

Production of intermittent renewable energy has risen significantly over the last decades. Therefore, new technologies are needed to keep high-voltage 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.

We provide a range of prefabricated substations that are equally suited for either temporary or permanent use in challenging grid expansion and maintenance programs.

High-voltage transmission assets are a critical part to supply high quality energy to our society. We have the unique competence as an OEM to render a comprehensive suite of services to keep your assets in service over decades. This includes spare parts, refurbishments, digitalization such as SIEAERO, our overhead power line (OHL) inspection technology based on drones and artificial intelligence, consulting and audits – even full service such as operation and maintenance contracts.

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).

HVDC technology offers an efficient means of transmitting large amount of power over long distances, helps to connect renewable offshore power to the grid, establishes grid interconnections between countries and stabilizes 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.
