influence on the O&M cost. An average (line in Fig. 4.2) for O&M cost is determined at 30 €/MWh (€ 0.03 per kWh), by calculating a boxplot based on the
middle 50%, omitting the maximum and minimum outliers, which are considered as
unreliable or exceptional (Miedema 2012).
To identify possibilities for synergy, a more refined O&M OPEX distribution is
necessary to identify activities which can be executed more efficiently by
