Delmarva Power proposes new $31.3m line to enhance reliability on Maryland’s Eastern Shore

Delmarva Power and Light is proposing to build a new $31.3m high-voltage transmission line between the Church substation in Millington, Md., and the Wye Mills substation in Wye Mills, Md.

The project is designed to enhance electric service reliability on Maryland’s Eastern Shore, especially for customers in Queen Anne’s, Talbot and Caroline counties, the company said on Feb. 6.

The existing 69-kV single overhead transmission line, which is currently on single wooden poles, will be replaced by a 138-kV and 69-kV, double-circuit overhead transmission line on more durable, single steel poles. The line’s length is about 26 miles.

“Engineering studies indicate that the new transmission line will help avoid extended power outages, should there be a major problem with the transmission and generation infrastructure,” Delmarva Power Region Vice President John Allen said in the statement. “This project is one of several similar transmission upgrade projects planned for the Delmarva Peninsula over the next several years, all of which demonstrate Delmarva Power’s commitment to continue to provide safe and reliable electric service for our customers.”

Delmarva Power said construction is scheduled to begin in January 2014 with completion by June 2015, and the company will coordinate the project with other utilities, local municipalities and the Maryland State Highway Administration to minimize disruption during construction. Most of the work will be done within the right-of-way.

Where necessary, Delmarva Power will coordinate its work procedures and schedule with any utilities that may be affected by the project, such as phone, cable television, water, as well as the Choptank Electric Cooperative, a Touchstone Energy Cooperative, a Delmarva Power spokesperson told TransmissionHub on Feb. 6.

“We will also coordinate the project with local municipalities, the Maryland State Highway Administration and the Maryland and Delaware Railroad Company,” he said.

Delmarva Power on March 30, 2012, filed an application for a certificate of public convenience and necessity (CPCN) with the Maryland Public Service Commission for authority to rebuild the Maryland portion of an existing 138-kV overhead transmission line from the company’s Church substation in Queen Anne’s County, Md., to its Townsend substation in New Castle County, Del.

The Maryland Public Utility Law Judge will hold a public hearing on the Church to Wye Mills project later this year, the spokesperson said. The hearing has not yet been scheduled.

Delmarva Power will host a community meeting on Feb. 20 in Centreville, Md., to provide information about the utility’s proposal.

The spokesperson said the Church to Wye Mills and Church to Townsend transmission projects are just two of several infrastructure improvement projects that will occur over the next several years in the Delmarva Power service territory.

Delmarva Power is a subsidiary of Pepco Holdings (NYSE:POM).
