MU Power at a Glance

Serving Morristown and Surrounding Areas

All together, MPS operates and maintains 39 miles of transmission lines, 412 miles of distribution lines, and thirty-five 13.2 kV distribution feeders which serve nearly 15,436 customers in the city of Morristown, TN.

3 Industrial Parks

Industrial/Commercial loads account or over 75% of energy sold. All distribution feeders are protected by state-of-the-art digital relays, providing the optimum in feeder coordination.  MPS also has over thirty 3-phase reclosers on distribution circuits to isolate faults and provide increased reliability to industrial customers.

Smart Metering

Smart metering allows for real time interaction with customers for improved outage management, power quality monitoring, peak load control and new products for cost savings.  Both the SCADA and Smart metering are enabled across our high speed Fiber to the Home optical network.

Power System Maintenance Evaluation

All distribution feeders are protected by state-of-the-art digital relays, providing the optimum in feeder coordination.  MPS also has over thirty 3-phase reclosers on distribution circuits to isolate faults and provide increased reliability to industrial customers.  MPS actively tracks outages and cause to monitor electric quality and reliability. MPS is committed to a Maintenance Program that is cost effective and ensures high reliability to all customers.

39 miles of transmission line and 412 miles of distribution line

The system load peak is 167 MW, all served by the Tennessee Valley Authority through two points of delivery.  MPS receives power at 161-kV from TVA at three delivery point substations and operates its own 69-kV sub-transmission system serving ten distribution substations in a redundant scheme.  MPS has twenty-eight 13.2-kV distribution feeders that feed power throughout the City.

Dedicated Monitoring

MPS monitors electrical system performance using a SCADA system at our Power Operations Center where dispatchers have real-time information of feeder loading and device status.  This system allows remote operation of equipment, alarm history and valuable performance information.

Diamond Level Certification

The American Public Power Association (APPA) awarded the Morristown Power System (MPS) with the Diamond Level certification of the RP3 Program for Reliable Public Power performance which benchmarks public power systems across the United States. MU scored a perfect 100 of a possible 100 points in the evaluation indicating a very high rating when comparing MU against other municipal power systems. The program evaluates municipal power systems in four major areas: Reliability, Safety, Workforce Development and System Improvement.

CO2 Emissions Rate

Morristown Utilities Commission’s CY2022 as-delivered CO2 emission rate average for our non-commercial and non-industrial customers is 671.11 CO2 lbs/MWh. The CO2 rates disclosed reflect TVA’s CY2022 renewable energy credit adjustment, which resulted in a reduction of 3.50 percent in its as-delivered CO2 lbs/MWh rate.  Consistent with generally accepted voluntary carbon accounting standards and in response to customer  requests, actual CO2 emissions have been annually allocated to customers in the same manner as costs.  Morristown Utilities Commission’s CY2022 CO2 lbs/MWh rate includes emissions and generation from owned and purchased power. TVA does not create or transfer RECs from any of its hydroelectric sources. Therefore, consistent with CDP guidance, any hydroelectric energy percentage disclosed by TVA in this disclosure letter can also be reported as renewable to CDP. This as-delivered aggregated generation was comprised of a power composition by source of:
• 31.951% natural gas,
• 15.285% coal,
• 0.007% diesel,
• 9.596% hydroelectric,
• 38.059% nuclear,
• 2.088% renewables (1.683% wind and 0.242% solar, 0.001% biomass and 0.162% biogas) and the
 remainder is
• 3.015% null power (includes REC-encumbered renewable sources that have not yet been retired to the generation mix or sold).
