Calculate the yearly replaced electricity production

NVP for g) is 31.1 million DKK

The offshore wind farm has a total capacity of 20 MW. The lifetime of the wind farm is 20 years. The utilization time of the wind farm is 2250 full load hours per year. This gives a total electricity production from the wind farm of 45000 MWh per year. Furthermore, use the NPV from the socio-economic valuation in exercise 4 to answer question g) (like in the in-class exercise). Assume that the power production of the wind farm will substitute an electricity production mix which consists of 70% coal and 30% gas. Technical data: The coal power plant would have used coal with a heating value of 25.25 GJ per ton of coal and a CO2 emission factor of 800kg CO2 per MWh of coal. The efficiency of the coal power plants is assumed to be 40%. The gas power plant would have used gas with a heating value of 39.51 GJ per ton of gas and a CO2 emission factor of 400kg CO2 per MWh of gas. The efficiency of the gas power plants is assumed to be 50%. a) What is the yearly replaced electricity production of the coal power plant in MWh/year)? b) What is the yearly replaced electricity production of the gas power plant (in MWh/year)? c) How many tons of coal is expected to be replaced annually by the wind farm (in tons/year)? d) How many tons of gas is expected to be replaced annually by the wind farm (in tons/year)? e) What is the total annual CO2-reduction of the investment (in ton(CO2)/year)? f) What is the total CO2-reduction over the life time of the investment (in ton(CO2))? g) What is the socio-economic benefit achieved by the CO2 reduction over the lifetime of the investment (in DKK/ton CO2)?
