Unit A needs refitting to increase availability from 80% to 98%. To force the refitting and have it made before the year 2021 will cost an additional 2 million during the year 2020. Without forcing the investment, the unit will be retrofitted by the year 2022. A dry year, we have anticipated that a change in price movements would contribute to 10x higher profitability compared to a normal year for unit A. A normal year profitability is about 2 million. There is a 45% chance that a dry year will happen in the year 2021. Should we force the investment? r=6%
