At the turn of the year, GP JOULE SERVICE surpassed the 2-gigawatt milestone for power plant capacity in operations management.

Over five years, GP JOULE SERVICE has doubled its contract volume in operations management. “I am especially pleased that the market recognises the quality of our services, allowing us to continuously expand our trustworthy relationships with customers,” says Markus van Hümmel, Managing Director of GP JOULE SERVICE. “Our primary focus is on managing the facilities throughout their entire life cycle.

Ongoing development and international activities
A team of approximately 80 skilled professionals oversees the energy generation plants across Germany and France. In photovoltaics, the comprehensive service offering includes not just commercial and technical management but also all services across the entire life cycle of the systems, such as technical consultancy, system optimisation, and solar repowering.
In the wind sector, GP JOULE SERVICE has recently expanded its portfolio to incorporate advisory engineering services, assisting operators in achieving operational risk management via inspections, SCADA data analyses, and condition monitoring systems.
