~LeGtrLC I . Purchased approximately 276.0 million kWh of energy, an increase of 4.6% from 2010. The system peak day was 57.7 MW. 2. ERMU's 201 I reliability indexes are: Average Service Availability (ASAI) = 99.994%, Customer Average Interruption Duration Index (CAIDI) = 105 min, System Average Interruption Duration Index (SAIDI) = 31.1 min, System Average Interruption Frequency Index (SAIFI) = 0.2966. These excellent reliability index numbers reflect the condition of our robust electrical system as well as our superb response time. 3. Continued system maintenance and fuse coordination through a systematic program to change failing cutout and resize system fusing. Changed out rusted electrical equipment, J-boxes, and switchgear. 4. Performed major service work changing gaskets on 35 electric switchgear cabinets due to a manufacture's material specification compliance issue for components of the switchgear. 5. Completed work on a voltage upgrading project changing from 2400 volt to 7200 volt along County Road 30 west of Waco Street. Began work on another voltage upgrade project changing from 2400 volt to 7200 volt along Meadowvale Road and Islandview Drive. 6. Continued work on rebuilding Irving, 4th, 5th, 6th, and 7th Street removing rear lot line overhead and replacing with underground electrical distribution in the front easements/ROW. 7. Purchased a directional bore rig and brought a significant amount of underground electric cable placement in-house. Initial forecast is a 2 year return on investment. A typical directional bore right has a 5 year life expectancy. 8. Miscellaneous projects: Rebuilt Baldwin Ave.; Relocated overhead electric feeders to facilitate City Public Works Building construction; Added 3-Phase service for Guardian Angels expansion, ERX snow cross track, Aggregate Industries, Barton Sand and Gravel, Spectrum School, Pizza Ranch, and others.
