I do not understand your question, what do you mean by LCI? Not 'system processes'? You can of course model a coal power plant (there are already exisiting datasets, in several databases), with unit processes.

Thanks Dear Ciroth for your reply, Actually I want to model a coal power plant with its upstream processes and change its efficiency to explore the effects of changing efficiency on environmental indexes. I would so glad if I could get your answer.

Ah I see - then you can make a compilation of the "inventory" of the plant (oven, heat exchanger, transportation belts, ...) and the material and coal (and type and specific preparation of coal) that goes into the plant, other material is chemicals and water used in flue gas cleaning e.g., and the electricity and maybe heat produced, and the related emissions. You will need the life time of the components of the plant, and can then "allocate" the impacts caused by their production to the plant and its product (e.g., 1 kWh, and per 1kWh you need 1e-10 pieces of transportation belts e.g.). This will be of course a somewhat complicated process data set, but you can check e.g. in the ecoinvent unit process database how this can be done. Good luck!

thanks very much. I would so appreciate if you could send me case study of coal-fired power plant.
Also I can not find out how for example coal transport has been modeled in coal power plant dataset. In, for example, NREL database, transport has been directly input in the coal power plant dataset while in the ecoinvent i cant see such thing.
thsnks for you help!

Hello! You can check out the process 'electricity production, coal' in an unit process-based ecoinvent version and you should be able to see how it was approached there.
