Lower Energy Prices to Decrease Average ComEd Residential Bills

New “Price to Compare” begins in June

CHICAGO--(BUSINESS WIRE)--ComEd today filed with the Illinois Commerce Commission (ICC) new rates that will decrease the amount residential customers will pay for energy supply beginning in June. This will contribute to an even larger decrease of about $2 in the total monthly average residential customer bill next January if the ICC approves the lower delivery rates that ComEd requested last month – its third rate decrease in a row.

Energy supply charges account for nearly half of the monthly residential customer bill, and ComEd passes these costs along to customers without profit or markup.

The new Price to Compare, which is the sum of the purchased electricity and the transmission services charge, beginning in June will be 6.473 cents per kilowatt-hour (kWh) compared to 7.175 cents per kWh in January. This reflects a new purchased electricity charge for residential customers of 5.168 cents per kWh for the summer period, a decrease from about 6 cents per kWh for the non-summer period that began in January.

New energy supply prices were established in the spring energy procurement event conducted by the Illinois Power Agency, which oversees purchases of energy on behalf of Illinois electric utilities ComEd and Ameren. The monthly transmission services charge, which is included in the supply section on ComEd bills, is increasing by about 30 cents on the average residential bill.

In April, ComEd asked for an $11.5 million decrease for the delivery of electricity compared to rates in effect in January of this year. With the new energy supply rates filed today, the average total monthly residential bill would be about $81 beginning in January of next year, which would be lower than ComEd customer bills in 2008.

Based on the most recent national data, ComEd’s combined rate for energy distribution and supply of 12.99 cents per kWh is below the national average and 20 percent below the average rate for utilities in the top 10 metropolitan areas by population.

The ICC posts the Price to Compare for ComEd and Ameren at Plug In Illinois, where customers can compare utility supply prices to offers from retail electric suppliers: pluginillinois.org.
