Our partnership with the Vivalia hospital group has taken on a new dimension in recent years thanks to two CHP (cogeneration) projects delivered in Arlon and Marche-en-Famenne. With these investments, Vivalia is committing not only to energy efficiency but also to lower CO₂ emissions and financially sound operations. For Luminus Solutions, this marks the continuation of a strong, long-term partnership.
Vivalia is a leading hospital group in the Province of Luxembourg with several sites, including the hospitals in Arlon and Marche-en-Famenne. For their energy projects, they sought a reliable partner with CHP experience who also understands their specific needs. Thanks to our long track record with the Arlon site, our expertise, and the right technical solutions, Vivalia once again chose our team for the new CHP in Marche-en-Famenne.
A long-term partnership
Our collaboration with Vivalia goes back more than ten years. In 2014, we built the original CHP installation for the Arlon site, a project that has proven its value year after year. This longstanding cooperation forms the basis of the trust Vivalia places in us. With our experience in designing, installing, and maintaining CHP in the healthcare sector—an environment where continuous heat and electricity demand is a perfect match for CHP—we remain the ideal partner for their energy projects.
Two recent projects
Over the past year in Arlon, we carried out a full overhaul of the existing 365 kWe CHP installation that we built in 2014. Thanks to this intervention, the unit—which had already accumulated more than 65,000 operating hours—can run for at least another 25,000 hours. In addition to overhauling the engine and generator, various components were renewed, pipes and pumps were replaced, and everything was thoroughly cleaned and tested. The installation was recommissioned at the beginning of 2024—perfectly timed for the heating season.
At the Hôpital Princesse Paola site in Marche-en-Famenne, we delivered a completely new CHP installation (357 kWe) based on a reliable MAN engine. Beyond installing the unit itself, we also integrated it with the existing electrical and heat networks, including a buffer tank for optimal operation. The installation was commissioned at the end of 2022 and has since been maintained and monitored remotely by our own team.
Only advantages
The benefits for Vivalia are significant:
-
The refurbished installation in Arlon has a payback period of only 2.5 years, while maximum use of green certificates is guaranteed until 2028.
-
In Marche-en-Famenne, the project will reduce CO₂ emissions by nearly 35%, thanks to an electrical efficiency of 38% and a thermal efficiency of 51%, with a payback period of just over 5 years.
Thanks to maintenance contracts and our 24/7 monitoring, Vivalia can count on high availability and operational reliability for both installations.
Proud of a sustainable collaboration
We are especially proud of the trust that Vivalia has placed in us for more than a decade. Together, we are not only delivering high-performance energy solutions, but also contributing to the hospital group’s sustainability objectives.
(It is a privilege for us to help build a future with lower CO₂ emissions, higher energy efficiency, and a reliable energy supply for healthcare institutions.)
