Hydroelectric category consists of both conventional hydroelectric and pumped storage. Gas Turbine and Small Scale category consists of gas turbine, internal combustion, photovoltaic, and wind plants. Notes: Expenses are average expenses weighted by net generation. A mill is a monetary cost and billing unit equal to 1/1000 of the U.S. dollar (equivalent to 1/10 of one cent). Total may not equal sum of components due to independent rounding.
