The town of Frederiksværk in the northern part of Zealand in Denmark has a population of around 13,000 inhabitants.

Frederiksværk Municipal District Heating company supplies almost 100 % of town with district heating.

In 2002-03, Ramboll worked with the city council to install a new wood-chip boiler plant that made the total heat supply of the city CO₂ neutral.

Early in the project, Ramboll prepared a feasibility study for the city council in which both the technical and the economic aspects of the project were compared to alternatives.

The report led to the only real logical conclusion - a new wood-chip boiler was both the most cost effective and efficient way to eliminate CO₂ emissions from the heating of all buildings in the town.

With the city council’s approval of the proposal, Ramboll took responsibility for the detailed design of the new boiler installations. We then followed through with procurement, construction management and commissioning.

The boiler was installed in an existing boiler house, joining another biomass fuelled boiler.
