Hayden Station Power Plant Maintenance System Preventive Maintenance Program. Final Report

摘要

Result of the CUEA Preventive Maintenance Program is that the number of corrective work orders at Hayden Station is decreasing while the amount of preventive maintenance work is increasing. Other results are: the need to perform work on a highest-priority basis has been reduced by 19%; overtime work, previously 11%, has been as low as 1/2%; the maintenance backlog has been reduced by 15%; maintenance costs are down by 26%; and direct maintenance work productivity has increased 6.2%. Equivalent availability (power generating capability) has improved 22% on generating Unit 1 and 11% on generating Unit 2; and forced outage rates are down 6.8% on generating Unit No. 1 and 2.3% on generating Unit No. 2. Although the final net cost benefit will not be known until after several years of operation, it is now estimated that the net benefit at the Hayden Station will be in excess of $1.0 million per year.
