Hitachi Energy’s EconiQ™ technology powers TenneT’s Maasbracht substation

Hitachi Energy will supply its pioneering 380-kilovolt (kV) EconiQ™ gas-insulated lines (GIL) to upgrade TenneT’s legacy substation in Maasbracht, a small town on the banks of the river Maas in southeastern Netherlands. The eco-efficient technology will enable TenneT to maintain a reliable electricity supply in Maasbracht and remove sulfur hexafluoride (SF₆) gas, considerably reducing carbon emissions.

TenneT is responsible for ensuring a reliable and secure electricity supply to more than 43 million domestic and business users across the Netherlands and Germany. As the first cross-border European Transmission System Operator (TSO), TenneT plays a pioneering role in the transition to a sustainable, decarbonized energy system, toward which it invests in innovative high-voltage technologies to minimize the use of SF₆ in the transmission network. The Maasbracht substation has been in operation for several decades and is the main connector between the Netherlands, Belgium, and Germany. The substation is a critical component of the country’s energy infrastructure and Hitachi Energy’s technology will modernize the substation by delivering over seven kilometers of its eco-efficient EconiQ GIL product, which uses a game-changing technology that eliminates polluting SF₆ gas and is proven to significantly reduce carbon footprint throughout its entire life cycle. By choosing EconiQ GIL, TenneT will achieve its sustainability goals by avoiding the addition of over 70,000 kilograms of SF₆ into the transmission network, which is the equivalent of removing CO₂ emissions from almost 826,000 cars from the road in a year¹.

Hitachi Energy is committed to supporting the energy transition with sustainable and innovative solutions such as EconiQ. This project is a testament to that commitment to enable a sustainable energy future for today’s generation and those to come.
