The “Smart Local Area Network” project celebrates its completion:
LACROIX confirms its leading role in smart grids in Germany

In June, the LACROIX Environnement business teamed up with wesernetz Bremerhaven to celebrate the completion of their “smart local network” project in the city of Bremerhaven in northern Germany.

LACROIX remote control systems (SAE computer systems in Germany) have been used by wesernetz Bremerhaven since 2011 for the monitoring and operational management of gas, water, district heating and electricity networks. As a network operator in the maritime city of Bremerhaven, the service portfolio of wesernetz Bremerhaven GmbH includes 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 over 2,700 kilometers long. The electricity network occupies approximately 1,292 km and has 78,964 E-house connections, including 306 km of medium voltage cables (20 kV). Wesernetz Bremerhaven’s annual electricity sales amounted to 478.9 million kWh in 2020.

As part of the outdated technology replacement project, local substations were upgraded to meet new network management requirements in terms of transparency and controllability, as well as security and reliability. For example, substations should always be switchable in the future, in order to guarantee 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 allows precise monitoring of the state of the network. A comprehensive redundancy concept and extensive IT security measures in accordance with ISO 27001 complete the project.

The project, which began in 2018, is now complete, 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 is that the project was completed without delay, despite significant challenges caused by the component crisis and the pandemic.

“We have been working successfully for 11 years with SAE IT Systems, a LACROIX brand in Germany, and are very proud to be able to complete this major project in Bremerhaven without any delays”, says Oliver Martens, project manager of wesernetz Bremerhaven GmbH, “thank you to LACROIX technology, we are well prepared for all the challenges of the electrical network in the years to come.”

“This project is a perfect illustration of our intelligent positioning, our know-how and our proximity to our customers”, continues Ronald Vrancken, President of LACROIX Germany, “a four-year project to retrofit the existing infrastructure with telecontrol stations to make it smarter and safer, all without delay. We are very grateful to have had the chance to help Wesernetz Bremerhaven switch to a smarter grid.
