Another Electric Utility Experiments With ‘Undergrounding’
The report recognized that full undergrounding of electrical systems is too costly to be feasible but recommended further investigation of several underground options, including burying service lines, placing new lateral distribution lines underground, to bury existing laterals when requested by a majority of the customers in an area, identification of "fully urbanized" main distribution lines that are at capacity limits and require burial when they are replaced, and burying main and lateral distribution lines that require relocation because of road and highway construction.
The state's other large power supplier, Public Service Co. of Oklahoma (PSO), has had an aerial to underground conversation program under way for several years. PSO, a business unit of American Electric Power, serves metropolitan Tulsa and portions of eastern and southwestern Oklahoma.
