2007 Missouri Electric Rates Among the Lowest in the Nation
Two of Missouri's key electrical rates were the fourth and seventh lowest in the nation in 2007, according to the Missouri Public Service Commission and U.S. Energy Information Administration.
Missouri's 6.25 cents per per kilowatt-hour (kWh, the industry standard measurement) for commercial service made it the fourth lowest for the 50 states plus the District of Columbia.

The Show-Me State's 7.57 cents/kWh for residential rates was seventh lowest in the nation.

Missouri's industrial electricity rate, at 4.73 cents per kWh, ranked the state 8th in that category.

An average of all the categories combined showed that Missouri was the 9th lowest in the nation for electric rates, at 6.48 cents per kWh.

Hawaii's position as most expensive state
for electricity hasn't changed since 2004. The net electricity
importer Aloha State was again the most costly overall for
electricity in 2007, at 21.29 cents/kWh.
Idaho was the least costly state for 2007 across all rate categories with industrial electricity costs, at 3.88 cents/kWh, residential at 6.35 cents/KWh, and commercial at 5.13 cents/KWh.
