While I am unsure about the different units for conventional vs. renewable energy, pricing for large scale power projects is generally reviewed on a per unit of generation basis, not a capital cost basis. That way the cost incorporates all costs, including operations, maintenance, financing, insurance, and so on, and also includes expected plant performance levels. The $/MWh cost to the utility is the fairest way to compare different sites and different technologies.
