Delmarva Power Seeks Change in Maryland Delivery Rates

SALISBURY, Md. -- Delmarva Power today asked the Maryland Public Service Commission (PSC) to authorize an increase in distribution rates in Maryland, the first delivery rate increase in more than a decade. If approved, the change would add about 3.4 percent to monthly residential electric bills and the typical bill for a Standard Offer Service residential customer using 1,000 kilowatt-hours a month would increase $4.48 from $131.95 to $136.43.
The proposed $20.3 million increase reflects ever increasing costs since the mid-1990s to maintain the poles, wires and critical high-tech equipment of the electric distribution system. The increase also would be used to improve reliability and support investment in new technology to keep pace with growth and increasing customer demand for power. At the proposed rate levels, Delmarva's distribution rates still will be below 1998 levels in inflation-adjusted terms.

Delmarva Power's customers have benefited from stable electric delivery rates for more than a decade while Delmarva Power's costs to provide safe and reliable service have continued to increase and the Consumer Price Index has recorded inflation of over 40 percent. In just the last three years, for example, the cost of transformers has more than doubled, and the cost of electric cable jumped 85 percent.

"While Delmarva Power remains committed to controlling its operation and maintenance costs, we know that our customers do not want us to sacrifice reliability in the name of keeping delivery rates flat," says Gary Stockbridge, President, Delmarva Power Region. "We recognize the strain that the higher supply costs have put on our customers in recent years and are doing all we can to keep our distribution rates as low as possible. The relatively modest rate increase we are seeking will help us maintain and improve our electric delivery system so that we can ensure the continued, reliable flow of electricity to our customers."

Distribution rates are separate from electric supply rates. Supply rates adjust annually to reflect the cost of power that Delmarva Power buys on behalf of its Maryland customers who do not contract with an alternative supplier. Customers who buy their electricity from a competing supplier will see the same increase in distribution rates, but their new total monthly bill will depend on the per-kilowatt-hour price charged by their supplier.

Supply costs are driven primarily by the cost of fuel to make electricity and were largely responsible for the increase in supply rates earlier this year for Maryland customers. 

If approved by the PSC, the new delivery rate for Maryland customers would become effective in the middle of June 2007.
