“Intelligent local grid” project celebrates its completion:
LACROIX confirms its leading role in smart grids in Germany

In June, LACROIX Environment activity joined wesernetz Bremerhaven to celebrate the completion of their "intelligent local grid" project in the northern German city of Bremerhaven.

Telecontrol systems from LACROIX (SAE IT-systems in Germany) have been in use by wesernetz Bremerhaven since 2011 for monitoring and operational management of the gas, water, district heat and electricity networks. As a network operator in the maritime city of Bremerhaven, wesernetz Bremerhaven GmbH's service portfolio includes the transport, storage and metering of energy and drinking water. Its supply area covers approx. 114,000 inhabitants, an area of 7,763 hectares with a pipeline network of over 2,700 kilometers in length. The electricity network takes up about 1,292km of this and has 78,964 E-house connections, 306km of which consist of medium-voltage cable (20kV). The annual electricity sales of wesernetz Bremerhaven amounted to 478.9 million kWh in 2020.

As part of the project to replace outdated technology, the local substations were upgraded to meet new network management requirements in terms of transparency and controllability, as well as safety and reliability. For example, substations must consistently be switchable in future, in order to ensure shorter downtimes in the event of faults. The connection of network analysis systems, short-circuit and earth-fault indicators as well as protection devices to the LACROIX telecontrol system enables precise monitoring of the network status. A comprehensive redundancy concept and extensive IT security measures in accordance with the ISO 27001 standard round off the project.

The project, which began in 2018, has now been completed, with a total of 422 LACROIX telecontrol stations installed to help ensure the future security of Bremen’s supply networks. What makes this even more remarkable, the project has reached completion with no delays, despite significant challenges caused by the component crisis and the pandemic.

"We have been working with SAE IT Systems, a LACROIX brand in Germany, successfully for 11 years, and are very proud to be able to complete this major project in Bremerhaven without any delays" says wesernetz Bremerhaven GmbH project manager Oliver Martens, "thanks to LACROIX technology, we are well prepared for all challenges in the power grid in the coming years."

“This project is a perfect illustration of our smart positioning, know-how and proximity with our customers”, continues Ronald Vrancken, President of LACROIX Germany, “a four-year project of retrofitting the existing infrastructure with telecontrol stations to make it smarter and more secure, all this without delays. We’re very grateful to have had the chance to help wesernetz Bremerhaven transition to a smarter grid.”
