Equity-Driven Approaches to Clean Energy Planning, Implementation, and EvaluationList All
Equity-Driven Community Engagement
The Equity Working Group developed and applied equity screening questions to the mitigation strategies discussed by the technical working groups. A portion of that group’s funding also supported direct outreach surveying community members to inform their discussions and recommendations. The facilitator worked directly with the Equity Working Group to craft the survey and compile results, and group participants that had the capacity to conduct surveys were compensated for their work. That outreach was geographically targeted to Knoxville’s lower-income zip codes. The Equity Working group delivered recommendations to staff that generally assessed a strategy’s ability to advance potential equity outcomes. When setting final lists of priorities and presentation of strategy rankings in the Sustainability Work Plan, staff deferred to the recommendations of the Equity Working Group on strategies that were most likely to advance equity outcomes.

The Knoxville Utilities Board (KUB), a municipally-owned utility (MOU), is the primary electric and natural gas utility for the City of Knoxville. The Tennessee Regulatory Authority sets the rates and services standards of the investor-owned natural gas, electric, and water utilities. The municipal energy utilities implement Tennessee Valley Authority (TVA)-funded energy efficiency programs, which are outlined in the TVA Integrated Resource Plan (IRP). To learn more about the state requirements for electric and gas efficiency, please visit the Tennessee page of the State Database.
The Knoxville Utilities Board also provides the City of Knoxville with drinking water services and wastewater treatment, while the City provides stormwater management.

Low-Income & Multifamily EE Programs List All
Low-Income Programs
KUB offers multiple low-income efficiency programs to best meet customer needs. KUB supports both electric and natural gas energy efficiency through its Round It Up program, which collects voluntary customer bill round-up contributions for low-income weatherization assistance. The program is administered by Knoxville-Knox County Community Action Committee (CAC), which administers a weatherization assistance program.
KUB also partners with TVA on the Home Uplift Program to provide low-income weatherization services to additional customers. Home Uplift addresses home comfort and health and includes measures such as air sealing, duct sealing/replacement, attic insulation, water heater, and pipe insulation, wall insulation, HVAC clean and tune, HVAC replacement, windows and door replacement, heat pump water heaters, refrigerator replacement, LED bulbs, and low flow showerheads. The program is funded by TVA, KUB Budget Contributions, and TDEC grant, and is administered by CLEAResult. In addition to weatherization programs, KUB also customers in need of immediate assistance utilize Bill Payment Assistance funds.
In addition, both Home Uplift and Round It Up provide additional resources for health and safety measures such as bathroom fans for gas homes, occupant safety repairs, electrical repairs, mechanical repairs, structural repairs, plumbing repairs, and moisture repairs. In addition, CAC administers a lead safety program and emergency home repair program which can be leveraged in conjunction with Round It Up.
The program has had approximately $700,000 contributed annually. In addition to customer funds, starting in 2021 KUB committed to $1 Million in annual contributions to weatherization programs. These funds along with KUB’s partnership with TVA’s Home Uplift Program build upon the Round It Up program to weatherize additional homes for families in need. Home Uplift has provided over $2 million since 2018, and together with Round It Up, over 500 homes have been served in addition to the 1,278 homes served through the Knoxville Extreme Energy Makeover from 2015 to 2017. In addition, the Tennessee Department of Environment and Conservation (TDEC) will provide $750,000 in 2021 and 2022 for weatherization in the KUB service area, and TVA will also provide an additional $75,000 to support the comfort and health benefits of weatherization.
As part of the City of Knoxville’s Smarter Cities Partnership, KUB works closely with community leaders and partners including the City of Knoxville, CAC, TVA, Alliance to Save Energy, Socially Equal Energy Efficient Development (SEEED) and others to develop, advertise, and implement the low-income weatherization assistance programs. In addition to weatherization assistance, KUB, in partnership with TVA, provides free home energy and water savings workshops to the community, with over 700 customers served since April 2019. Customers who attend the workshops receive free conservation kits, valued at more than $40.
In 2021, according TVA, KUB achieved 405 MWh an in energy savings through TVA programs, while spending $14,723,248 on electric low-income programs, which includes spending for KUB, Memphis Light, Gas, and Water, and Nashville Electric Service Programs. According to TVA, KUB served 176 customers in 2021. We were unable to verify the natural gas savings, spending, and customers served data in 2021 for KUB.

Efficiency Efforts in Water ServicesList All
Citywide Water Efficiency and Goals
KUB is the water utility in Knoxville and an EPA WaterSense partner. KUB, in partnership with TVA, is providing free energy and water conservation workshops to the community. KUB has presented workshops to over 800 customers since April 2019, and workshop attendees receive conservation kits valued at more than $40. The kits include water conservation measures. Additionally, through a current partnership with the City of Knoxville, CAC, and others, some water efficiency measures are being installed in some of the homes being weatherized through KUB’s Round It Up program.
At this point, the City of Knoxville has not established a water savings target or goal.
Water Plant Efficiency and Self-Generation
KUB has made significant investments to improve energy efficiency. Plant efficiency has been optimized with the installation of efficient equipment (e.g., variable frequency drives) and operational adjustments. KUB has had multiple energy assessments of its plants conducted by third parties. One such assessment was conducted by the State of Tennessee in 2015, and the results noted KUB’s plants are extremely efficient and there is little more that can be done to improve efficiency. Still, KUB strives for efficiency in its water and wastewater operations, and recent efforts include installing LED lighting, participating in TVA’s demand response program, improving aeration systems, and implementing advanced technology to prevent water loss.
In addition to water and energy conservation, KUB is a Platinum-level participant in the National Biosolids Partnership, through which all of the organic solids (approx. 33,000 wet tons per year) from the wastewater treatment process are certified as fertilizer by the Tennessee Department of Agriculture and applied to regional farmlands at no cost to the farmers. An interdisciplinary team within KUB remains active in exploring additional efficiency opportunities. Implementation of data analytics software is scheduled to support efficiency efforts.
KUB’s Kuwahee (KUW) Wastewater Treatment Plant (WWTP) produces approximately 359 MMBTU of biogas per day. Biogas is captured for direct use of two processes at the plant including mixing and heating sludge. Biogas used for the heating process is redirected away from the environment and provides an alternative to natural gas.
