Background• North Bethesda is quickly becoming
a center for economic development• The area is transitioning from a
suburban to an urban environment• Major development is occurring
along the I-270 corridor and the White Flint area
• Significant capacity growth is expected in the region
3
North Bethesda Future Development
North Bethesda continues to grow, with more than 10 million sq. ft. of development slated for the area
Project Overview• We are constructing a new 69kV/13kV
distribution substation in the White Flint area• The White Flint substation will allow us to
continue to deliver safe, reliable, affordable, and sustainable energy to nearby families and businesses in the growing North Bethesda area
• Reliability enhancement work includes extending current 69kV and 13kV feeders from surrounding substations to White Flinto This involves both underground transmission and
overhead transmission construction

Project Design
• The design of the project was a multi-year process including several alternative analyses, community meetings, and discussions with permitting authorities
• After extensive analysis, Pepco and its specialty vendors designed the substation and feeder extensions to meet the demands of the surrounding area with consideration for future growth
• All aspects of the design – location, equipment type, and architectural aesthetic –were considered and incorporated into the final design

Project Status• 13kV and 69kV underground duct banks are
being installed along Nebel St., Marinelli Rd., Old Georgetown Rd., Citadel Ave., Randolph Rd., and Parklawn Dr. to provide a pathway for electrical cabling
• Civil construction started in April 2020 and is expected to be completed in 2022
• Seven new overhead steel poles will be installed along Randolph Rd., Parklawn Dr., and Nicholson Ln.

Upcoming Project Construction• On Aug. 30, Pepco's construction contractor, CW &
Sons, will begin a 6-month construction effort on thewestbound lanes of Randolph Rd., between Nebel St.and Parklawn Dr.o Work includes excavation of two micro-tunnels under the
CSX railroad tracks
• Westbound lanes of Randolph Rd. will be closed, and allwestbound traffic will be detoured to Parklawn Dr.
• Eastbound lanes on Randolph Rd. will remain open totraffic
• Businesses located along the westbound side of thisstretch of road will remain open throughout theconstruction and will be accessible via the eastboundlanes of Randolph Rd.
• Sidewalks on Randolph Rd. will remain open topedestrians throughout construction
9For construction updates, please contact Shamyra Edmonds, Project Ombudsman, CW & Sons
Safety Is Our Top Priority
• We’re coordinating with the Montgomery County Department of Transportation to create traffic control plans to ensure work is done safely and to minimize disruption o Appropriate signage and flaggers will be used to direct
traffic for the detour and to access businesses o Please use caution when driving near work zones
• We’re committed to minimizing impacts to pedestrians and businesses and appreciates the cooperation and understanding of residents as we continue to perform this important reliability enhancement work in the area
10
Keeping You Informed• We welcome the opportunity to work with residents and
business owners to gather feedback and input • We’re committed to keeping you informed every step of
the way
