cost of electricity per kwh?

best answer
As you can see commercial electricity rates are lower than residential prices across the US. The only exception is Washington DC where the average commercial rate (14.95 cents/kWh) is higher than the residential rate (14.04 cents/kWh) by 6.5%. There are 18 states with average commercial rates below 10 cents/kWh and all states with the exception of Hawaii have average rates below 20 cents/kWh.
