Exelon’s (NYSE:EXC) Delmarva Power on Feb. 12 said that it has energized two major substations, totaling more than $24m, to enhance electric service for more than 15,400 customers across Wicomico and Queen Anne’s counties in Maryland.
Company spokesperson Jake Sneeden on Feb. 18 told TransmissionHub that the 69/25-kV Hebron substation in Hebron, Md., in Wicomico County, represents an approximately $11m investment, and that the 138/25-kV Carville substation in Centreville, Md., in Queen Anne’s County, represents an approximately $13m.
Tyler Anthony, senior vice president & COO, Pepco Holdings, which includes Delmarva Power, said in the statement: “Maintaining the safe and reliable service our customers expect requires ongoing efforts to modernize the local energy grid. Energizing these new substations helps us continue to meet this commitment and deliver record electric service reliability for our customers.”
Substations, like Hebron and Carville, reduce the voltage of electricity as it is delivered across the region to homes and businesses, Delmarva Power said, adding that the new substations, which were built by Delmarva Power and local contract crews, will help deliver energy more efficiently and create new configurations on the local energy grid that allow Delmarva Power to automatically restore service more quickly or isolate damage. By automating certain functions on the electric system, the new substations create a smarter energy grid and reduce the number of potential outages in the neighborhoods they serve, the company said.
Delmarva Power said that the new substations are part of a broader reliability improvement plan that the company is implementing on the Eastern Shore to reduce outages and enhance the resiliency of the local energy grid. That effort includes modernizing infrastructure, such as transmission and distribution lines, and adding greater automation on the local energy grid with new substations and equipment, the company noted.
Noting that it has invested hundreds of millions of dollars across its service area to modernize the local energy grid over the last five years, Delmarva Power said that its customers continue to benefit from the enhancements being made and have seen the frequency of outages decrease 34%.
The company also noted that energy delivery charges on customer bills pay for important projects, like the new substations, that help deliver energy to customers in Delmarva Power’s service area. Delmarva Power said that it spent more than $425m in 2018 to enhance the local energy grid and provide safe and reliable service for customers.
