Delmarva Power & Light Co. is seeking to recover $18.5 million in costs related to spending on infrastructure reliability improvement projects.

In a filing with the Maryland Public Service Commission, the Exelon Corp. subsidiary requested to recover investments on: building two major substations in Hebron and Centreville, Md.; upgrading transmission lines, one in Talbot County and another between the North Salisbury and Hebron substations; and replacing underwater cable running beneath the Isle of Wight Bay, as well as installing newer equipment to increase electric system capacity.

If approved by the commission, a typical residential customer using 1,018 kWh per month will see a bill increase of about $5.10, or 3.6%, according to a Dec. 5 news release.

The company said over the past five years the number of electric outages on its system has decreased by 34%.
