Variable fee
Variable fee means the annual fee component paid by the first bundled unit on a site with a licensed thermal power rating greater than 250 MWt and less than or equal to 2,000 MWt; or the annual fee component paid by additional bundled units on a site that have a licensed thermal power rating of less than or equal to 2,000 MWt. The variable fee is the product of the bundled unit thermal power capacity (in the applicable range) and the variable rate.
