on the Finnish electricity market at the moment. The power plant already exists
so this kind of calculation does not take into account the investment cost. The price of hard coal in the port of Rotterdam is currently around 25 Eur/MWh (fuel). Let’s assume that shipping coal from Rotterdam to the Meri-Pori power plant costs 10 Eur/MWh of fuel. The efficiency of Meri-Pori’s electricity production is 44%. Let’s assume that Meri-Pori runs at full production capacity all the time
i.e. 565 MW of electricity. In addition to fuel costs
the plant’s variable cost of electricity production is 6 Eur/MWh per unit of electricity produced. It is assumed that there is no fixed operating cost. In late autumn 2022
the average price of electricity on the Finnish market was around 180 Eur/MWh. Let’s assume that this price is now constant every hour.
