For example, in 2012, Hawaii residents had the highest average residential electricity rate in the United States (37.34¢/kWh), while Louisiana residents had the lowest average residential electricity costs (8.37¢/kWh). Even in the contiguous United States the gap is significant, with New York residents having the highest average residential electricity rates in the lower 48 U.S. states (17.62¢/kWh).
That means that customers in Houston paid an average of $5,500 more for electricity over a 14-year time span beginning in 2002, according to the group that buys electricity on behalf of municipal governments in Texas. The calculation, which uses data from the U.S. Energy Information Administration, assumes monthly electricity use of 1,300 kilowatt hours.
Once you sign up for your new energy plan, your local utility will be notified of the change and begin your service from the alternative supplier at the beginning of your next billing cycle. Upon starting your energy supply service, your utility company will include this charge on your energy bill and continue to charge for the delivery service portion of your bill. Why? Because although your supplier may offer you a competitive rate for electricity supply, your utility is still in charge of the infrastructure that delivers energy to your home – such as power lines and energy meters.
Twenty-nine states have deregulated electricity, natural gas or both. That allows you to shop for the supply portion of your bill from alternative providers who may offer rates lower than the default supplier – usually a utility. Delivery services and billing will remain the responsibility of the local utility as they own the power lines and wires that keep the lights on.
