Delmarva Maryland filed a petition July 14 with the Maryland Public Service Commission to authorize a base rate adjustment of $27 million to recover infrastructure investments that led to Delmarva’s significantly improved reliability.

The rate adjustment would increase a typical residential customer’s total monthly bill by $2.78, or 1.91 percent.

In 2016, Delmarva Power had its best reliability performance in recent history, due in part to $68.1 million the company spent in 2016 to improve its Maryland distribution system reliability and to enhance customer service. These investments, which did not represent an increase in budgeted spending, include replacing aging infrastructure, making targeted distribution system upgrades, implementing storm protective measures and expanding system capacity. During 2016, Delmarva Power implemented projects to improve safety, reliability and customer service, while enabling customers to reduce their overall bills through efficiency gains and energy conservation.

Those projects included:

— Upgrading 56 feeder power lines.

— Replacing 35.7 miles of underground cable.

— Replacing equipment at 16 substations.

— Installing 69 reclosers, or equipment to auto-restore power after momentary interruptions.

— Repairing or replacing aging equipment such as broken cross-arms, poles or transformers.

— Work on multi-year projects to add additional substations and upgrade others in the

Centreville and Salisbury districts.

From 2013 to 2016, the company invested over $302.2 million in Maryland distribution reliability projects. Since 2012, Delmarva Power Maryland customers have seen 29 percent fewer outages and a 43 reduction in the duration of outages.
