Transmission Line Operating & Maintenance Expense per Circuit Mile

Transmission Line Operating & Maintenance Expense per Circuit Mile

KPI Details

Transmission Line Operating & Maintenance Expense per Circuit Mile measures the total transmission line operating and maintenance-related expense incurred by the company in relation to the number of transmission pole line miles available over the same period of time. A relatively high value for this metric is typically related to a few common factors, including overstaffing, general inefficiencies within the utility company's operating and maintenance practices (e.g., poor equipment maintenance, poor management of equipment installation, insufficient planning of where transmission poles should be located, etc.) and sub-par maintenance employee training and performance. Excessive values for this metric can lead to high rates of power supply issues which reduces customer satisfaction and increases customer attrition rates.

KPI Definition

The total transmission line operating and maintenance-related expense incurred by the company divided by the number of transmission pole line miles available over the same period of time.

KPI Best Practices

• Proactive maintenance measures to minimize the need for full repairs
• Regularly audit and monitor vegetation control processes to reduce instances of outages
• Develop a system to monitor substation, power line and transformer efficiency in real time

KPI Calculation Instructions Transmission Line Operating & Maintenance Expense per Circuit Mile?

Two values are used to calculate this KPI: (1) the total transmission line operating & maintenance-related expense incurred, and (2) the number of transmission pole line miles available over the same period of time. Include transmission poles used to carry subtransmission lines (power lines that carry higher voltage power between substations) and distribution lines (powerlines which distribute lower voltage power to customers) in the denominator. Include labor (wages, salaries, commissions, benefits), overhead (occupancy, utilities, supplies, advertising, legal fees, travel costs, etc.), and technology (hardware, software, etc.) costs in the numerator.

KPI Formula :

Total Transmission Line Operating & Maintenance Expense / Number of Transmission Pole Line Miles
