Sønderborg Varme secures a greener future
Sønderborg Varme has many technological initiatives underway to ensure greener district heating production.
Together, we integrate the right heat production technologies and connect multiple district heating consumption areas.
A greener district heating
Advising Sønderborg Varme on the transition to green district heating and utilization of excess heat.
Sønderborg Varme is facing the complex task of ensuring a green and sustainable future for district heat production. This involves not only implementing various heat production technologies but also efficiently interconnecting multiple district heating zones — a challenge that requires careful planning and coordination.
While converting to green district heating is technically feasible, doing so in a way that also guarantees economic viability and supply robustness is a far greater challenge. That’s where we step in. With our expertise, we support the development of a detailed roadmap that outlines both the timeline and approach for implementing new heat sources — while phasing out older plants. We optimize the plan to ensure the system remains resilient and flexible, even in the face of future changes in regulations and market conditions.
The figure to the right shows the new transmission line to be built between Dybbøl and Adsbøl, as well as the gas-supplied areas that include the towns of Nybøl and Vester Sottrup. Added Values has prepared a project proposal aimed at connecting Nybøl and Vester Sottrup to the existing district heating network, thereby extending the reach of green heat supply. The project also includes the construction of a transmission line between Dybbøl and Adsbøl and the installation of a biomass boiler in Gråsten. This new infrastructure will effectively link Sønderborg and Gråsten, supporting a more sustainable and cost-efficient heat supply for the region.
Sønderborg Varme’s green transition strategy and collaboration with Added Values
Project and Development Manager Tue Gejl Christensen from Sønderborg Varme shares insights into the company’s strategy for the green transition of its district heating system. He explains how Sønderborg Varme is working to implement new sustainable heat sources and adapt its infrastructure to meet future energy demands.
Tue Gejl Christensen highlights the important role that Added Values has played as a strategic partner in this process — contributing with expert advisory services, technical solutions, and meticulous planning of district heating projects. Their ability to develop detailed roadmaps and evaluate investment scenarios has been crucial in ensuring that all initiatives are both effective and economically sustainable.

AVPLAN-model
The purpose of AVPLAN’s calculations and its various visual representations is to provide clients with a solid foundation for making well-informed decisions. In close collaboration with the client, AVPLAN helps identify which energy solutions to invest in, where to place them, and when to implement them.
The figure to the right shows the Sønderborg Varme system as represented in the AVPLAN model. It illustrates both existing assets and investment opportunities, along with their respective locations.
Our AVPLAN software is built using the GAMS modelling language. It has been continuously developed over the past 10 years — and we keep refining it to meet the growing demands for climate-neutral energy solutions.
