Notes: Data for the years 1997 - 2007 were updated reflecting revisions reported by Energy Velocity. 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). Totals may not equal sum of components because of independent rounding.
