Power Struggle

by Jerry Wong, P.E., Transmission Design Engr.; Florida Light and Power Co., Juno Beach, FL,


Serial Information: Civil Engineering—ASCE, 1999, Vol. 69, Issue 6, Pg. 48-51


Document Type: Feature article

Abstract:

The Florida Light and Power Company could have replaced its deteriorating, H-shaped wooden power poles in the Tomoka River with exact duplicates, but they chose to use hybrid steel-and-concrete single poles instead. By locating the poles on the river's banks instead of in the river itself, as the old H-poles had been, FLP saved the $190,000 it would have taken to bring the poles up the river by barge. Limited easements for guy wires and high wind loads on the 66-m-tall poles were among the challenges the designers overcame. The new power line crossing leaves a higher clearance for boats, creates nests for endangered birds and produces a more community-friendly river crossing.
