The time period under consideration was assumed to be reasonable at 30 years, over which the construction time was assumed to be three years, allocating 8% of the total investment costs to the first year, 60% to the second year and 32% to the third year
(Humbird et al., 2011). An additional expense of 7% of the fixed capital investment and reduced revenue of 50% in the first year were estimated as start-up costs. Within the time period under consideration reinvestments of equipment and plant units are considered. Thereby, the depreciation capital is calculated linear according to depreciation tables of the German Federal Ministry of Finance.
