Michels Power, Inc. worked with an East Coast utility company to transform a 240-acre site on top of a closed coal mine into a 230kV electrical substation in Scranton, PA.
The substation has four-bay 230kV side that converts power from incoming transmission lines and a five-bay 69kV side that sends it out to neighborhood transformers that steps it down to 12kV to enter homes and businesses. Michels Power installed the transformers, buses, control house, conduits and wiring.
Michels Power also constructed 240 7-inch micropiles with rock sockets from 10 to 100 feet deep and drilled 190 shafts that ranged in diameter from 3 to 6.5 feet and up to 87 feet deep with 50-foot rock sockets. Because the project is located over a closed coal mine, the micropiles and shafts were extended through the void of the coal mine and into the rock layer below for stability.
Rock was encountered as close as 3 feet below grade.
Michels Power completed all the concrete work.
