The use of steel utility poles is gaining ground in the mid-Atlantic states.This is evidenced by Delmarva Power’s continued conversion from wood to steel utility poles over the past few years. Delmarva Power, a subsidiary of Pepco Holdings, Inc. (PHI), is the electric power provider to more than 506,000 electric delivery customers in Delaware and Maryland and nearly 126,000 natural gas delivery customers in northern Delaware. The utility’s service area covers some 5,000 miles, including a considerable amount of coastline on the Chesapeake Bay and Atlantic Ocean, and strong winds are a fact of life. In an effort to update its aging system infrastructure for greater durability, resilience and reliability, Delmarva has initiated a number of key capital projects that are primarily focused on converting aging wooden power poles to safer, more weather-resilient galvanized steel poles.

One way that APS has found to harden its line as well as make it resilient is by replacing downed wood poles with steel poles. Continue reading
