| Sumario: | District heating covers most of the residential areas and industries in the two
neighbouring Swedish municipalities Nyköping and Oxelösund. In Nyköping,
Vattenfall AB Värme produces heat in a bio-fuelled CHP plant. In Oxelösund,
waste heat and use of waste gases from the steel production at SSAB
Oxelösund is the basis in the district heating system.
This report examines the environmental consequences of a connection between
the two district heating systems. A broad system approach is used and the focus
is on environmental effects in the system.
A system analysis has been performed on the result of simulations of different
heat and electricity production alternatives. The alternatives simulated were
one where Vattenfall Nyköping covers the base load in the joint district heating
system and two where the power plant at SSAB Oxelösund supplies the heat
base load.
The conclusion in this report is that the consequences of connecting the two
district heating systems can be both positive and negative, depending on
system boundaries and on the environmental focus. An efficient use of
resources can be achieved by letting SSAB Oxelösund supply the base load of
heat in the system. Such a solution will lead to a decrease in electricity
production in Nyköping and Oxelösund. This might not be desirable since a
large part of this production is renewable. With a focus on renewable
electricity production the first alternative, with base load production at
Vattenfall Nyköping, would be the best alternative. |
