4.5 Assumptions
A number of assumptions have been used throughout the project and they are all listed in the
following sections.
4.5.1 Production
The plant was assumed to have 8 400 h of production each year. This corresponds to 50
weeks of full production during one year, the summer vacation and the reduced production
rate during Christmas taken into account. The measured weeks were assumed to represent a
standard production week and all calculated electricity consumptions for each week was
multiplied with 50 to get figures for one year. The calculated utilization ratios were also
assumed to represent a standard production week.
