Studstrup and Avedøre power stations are gearing up to change their primary fuel source from coal to biomass. The two plants will together make a significant contribution to the increase in green electricity production and district heating in Denmark.

Communities around Aarhus and Copenhagen can look forward to receiving heat and power derived from green energy.

When Studstrupværket and Avedøreværket convert from coal to wood pellet based energy production during 2012 and 2014, they will probably be the world's largest biomass conversion schemes. The silo installations in itself will hold 100,000 tons biomass.

"These conversion projects mean that it will be possible to deliver carbon free electricity and heat that can meet a large proportion of the heat consumption in areas around Aarhus and Copenhagen. Together, the two plants are some of the largest in Denmark. This means that we will see a significant increase in green district heating in Denmark, " says Mogens Skov, vice director of Ramboll 's power division.

Modernise

Ramboll is undertaking the projects for DONG Energy and is responsible for overall advice about the conversion process throughout the supply, design and construction phases.

The project will see the conversion of a block at Avedøre and another block at Studstrup and includes the development of unloading facilities, transport systems, coal mills, boilers, storage facilities and buildings.

Ramboll consultancy role also extends to conducting the technical and economic assessments needed to identify which components are worn out and must be replaced or modernised.

A model for international power development

The projects have attracted a great deal of attention internationally - especially in Germany, Sweden and England. The interest from Germany has been triggered by their decision to start phasing out their nuclear power plants, whilst the Swedes are experiencing a large growing market for biomass, and the English are faced with an aging portfolio of fossil-fuel power plants that need to be replaced.

"Other countries are very interested in Denmark's expertise in plants, district heating systems and large heat storages. Our main strength lies in thinking holistically and integrating district heating systems across consumption patterns, production demands and fuel types. In addition, we have unique capabilities in relation to energy production from biomass. This makes Denmark a model for other European countries that are now looking to convert from fossil-fuels to green energy," adds Mogens Skov.

Studstrup CHP and Heat Plan Aarhus was in 1981 the first to be approved in accordance with danish energy legislation. Avedøre CHP was the first CHP at a new site near a heat market in accorcance with the legislation. Today all EU-cities have to consider this in accorcance with EE-directive.
