100kw wind turbine for private project

I’m investigating the costings for the installation of a 100kw wind turbine with 50% used on site and 50% back to the grid. I’ve found all sorts of figures on line non of which seem to answer the one basic question I have.

How much roughly can we expect to earn from the 50% that goes back to the grid? I realise its winde dependent but if someone can just give me a ball park figure I’d be very grateful.

I think they purchase power from private generators.
