Data behind our tables

Source
Prices are the average residential price per kWh for each state and D.C. from the U.S. Energy Information Administration, Electric Power Monthly, Table 5.6.A, copied as published. EIA marks its most recent month as a preliminary estimate. Costs are calculated from those prices with the method listed under each dataset; nothing is estimated or adjusted by hand.
