In February 2026, Luminus Solutions secured the contract for the turnkey integration of a new CHP unit at the Centre Hospitalier Régional de la Haute Senne in Soignies. This project was the result of a thorough feasibility study and highlights the continued relevance of CHP technology in the energy transition: the hospital achieves significant energy savings and improved efficiency, with limited CO2 emissions.
The Centre Hospitalier Régional de la Haute Senne (CHRHS) in Soignies has made strong efforts in recent years to improve energy efficiency. Through an ambitious program of energy-saving measures, the hospital succeeded in significantly reducing its energy consumption. These efforts also created a new opportunity: due to the achieved savings, the existing boiler room had become oversized, leaving room for the integration of a combined heat and power unit.
From feasibility study to implementation
After an extensive feasibility study, which examined the hospital’s energy needs and explored various scenarios for their technical and financial viability, a CHP installation of 125 kWe was initially dimensioned, optimally aligned with the hospital’s energy demand after the implemented efficiency measures.
One of the main challenges of this project was integrating the CHP unit into the limited space of the existing boiler room. The hospital did not have extensive technical areas available, requiring a compact and well-thought-out solution.
Luminus Solutions therefore opted for a custom-made CHP unit of 139 kWe, specifically designed in a compact format to ensure optimal integration into the hospital’s boiler room.
The turnkey integration has recently been launched and includes not only the delivery and installation of the CHP unit itself, but also all necessary auxiliary equipment, which will be integrated into the existing boiler room:
- Electrical integration into the existing switchboard
- Hydraulic connections with the existing heating system
- An exhaust system with silencer to limit noise disturbance
- Acoustic enclosure to further reduce noise levels
- Ventilation adapted to the boiler room
- Energy meters for accurate monitoring
- Advanced control systems
A reliable installation with strong energy performance
Once installed, the CHP unit will achieve a total efficiency of 87%. This means that 87% of the input energy is converted into useful electricity and heat, a significant improvement compared to the separate generation of the same energy.
With an expected operating time of 6,000 hours per year, the installation will make a substantial contribution to the hospital’s energy supply. The electricity produced will be consumed on-site, while the heat will be used for heating and domestic hot water.
The installation also complies with strict emission standards, with NOx emissions of a maximum of 125 mg/Nm³ and CO emissions of a maximum of 150 mg/Nm³ (at 5% O2), contributing to improved air quality.
In addition to the total efficiency of 87%, Luminus Solutions also guarantees high availability of the installation thanks to a comprehensive all-in maintenance contract over a period of 10 years.
CHP, a building block in the energy transition
The new CHP unit at CHRHS is a strong illustration of the ongoing relevance of combined heat and power technology in the energy transition. While electrification and renewable energy sources such as solar and wind remain at the forefront, CHP technology offers a complementary solution that ensures a flexible and reliable energy supply with high efficiency, independent of wind, rain, or sunshine.
For hospitals, which require both electricity and heat 24 hours a day, CHP is an ideal technology. The continuous demand for heat for heating, sanitary hot water, and sterilization ensures optimal use of the generated heat, resulting in significant energy savings and a fast return on investment.
Moreover, the project contributes to the hospital’s CO2 reduction objectives. Due to the high efficiency of the CHP unit, less primary energy is consumed compared to separate generation, resulting in lower CO2 emissions per unit of energy produced.
Provisional acceptance is scheduled for November 2026, after which the hospital will benefit from energy savings and increased energy efficiency. The project reaffirms Luminus Solutions’ position as an expert in high-performance energy solutions for the healthcare sector and demonstrates that CHP technology continues to deliver strong results in the transition toward a more sustainable energy supply.
