I'm doing an LCA for wind electricity generation. From the tutorials and webinars that I have been watching, I got to know where/ how I should import the input materials (e.g. metals used for manufacturing the wind turbine, etc) but I still don't know what I can do with the capacity (e.g. 2MW wind turbine) and lifetime..etc., which cannot be expressed as per unit of electricity (e.g. 30 kg of nickel required per MWh of electricity). But most of the wind electricity LCA papers mention the capacity of wind turbine, but don't mention what they do with it. Am I supposed to calculate the annual electricity generation based on the capacity and make it into per unit of electricity?
What about the lifetime? If I assume 5 maintenance works are required for 20 years of lifetime of the wind power station, how can I import those maintenance data (e.g. 1kg of lubricant oil is required per maintenance, so 5kg in total during the 20-year lifetime) into OpenLCA?
If anyone can help me out, that would be great.
Thank you in advance.
