Abstract:

In May, 1989, the Western Area Power Administration and the Bureau of Reclamation published a report entitled Replacements: Units, Service Lives, Factors. This report showed that equipment lives have significantly shortened for substation and switchyard equipment and for the associated supervisory control and communications networks since the last study was published in August, 1981. A shortened service life has a simple resulting impact - increased revenues are required to replace retiring equipment.
