The Tennessee Valley Authority (TVA), the largest public power provider in the United States, via its EnergyRight program has a straightforward mission: serve the Tennessee Valley by delivering affordable, reliable energy while conserving natural resources and supporting economic development.

Over the years, TVA has built a strong residential rebate program covering technologies like HVAC, duct sealing, refrigeration, and others. Heat pump water heaters (HPWHs), with their high efficiency and major utility bill savings potential, recently emerged as a natural fit in the residential rebates portfolio and have become a key part of TVA’s energy savings strategy. In 2025, due to a large incentive and successful program design, TVA EnergyRight saw sales of the product increase dramatically.

The First HPWH Rebate Attempt: Downstream Model

TVA Energy Right’s HPWH journey began in October 2023 with an $800 rebate (called a downstream model) directly to homeowners and builders. But after a full year, participation stalled at only 90 rebates. A conversation with contractors led to the core issue: suppliers and retailers simply weren’t stocking HPWHs. Without inventory, homeowners couldn’t buy them, contractors didn’t trust they could install them, and the rebate program couldn’t gain momentum.

This pushed TVA EnergyRight to take a step back and rethink the entire approach.

Rethinking the Strategy: A Quick Pivot — Upstream Model

In late 2024, TVA consulted with Efficiency Maine and its collaborators to identify barriers and strategic solutions for implementing a successful HPWH incentive model. Maine has the most successful HPWH program in the country and has been teaching the rest of the nation how to replicate its success. After consulting with Efficiency Maine, TVA explored a rebate strategy where they incentivized HPWH manufacturers directly (called an upstream model). But within just three weeks of testing the idea, in early 2025, TVA realized this model wasn’t its ideal long-term solution. Long payment timelines and limited data made it difficult to scale this program for the long term.

What Finally Clicked: The Midstream Model

The breakthrough came in March 2025, when TVA EnergyRight shifted to a midstream program focused on incentivizing distributors and retailers (which Maine has also perfected). This new model offered a $1,300 discount on a HPWH at checkout, making the price drop instant and lucrative for customers. To keep things simple, TVA removed barriers like requiring an installation address or proof of whether the old water heater was gas or electric. The goal was to make HPWHs an easy, affordable choice.

Distributors also received an administrative fee ($50) for reporting data and supporting customers, while contractors earned a $50 compensation for providing installation details. EnergyRight also built a geographic eligibility system using mapping tools, focusing on locations where at least 70% of the service area fell within the Tennessee Valley. They made exceptions for areas near national parks and regions with low population density to keep participation flexible. On their website, they have included an energy savings calculator designed to help consumers estimate their annual energy savings when they switch to an HPWH.

The Results: Incredible Growth and New Momentum

The midstream model delivered results almost immediately and was supported by simple yet effective marketing materials like flyers and QR codes. More than 1,500 HPWH sales were reported by early October, a 1600% jump from the previous year’s rebate number (90). By late October 2025, the program was supported by 12 distributors and 176 participating locations, achieving a remarkable 4 gigawatt-hours of energy savings overall.

The impressive sales before October then paled in comparison to the end-of-year surge in HPWH sales. Since October 1, over 10,000 units have been rebated through the program, far beyond what was anticipated. To put this number into context, nationwide HPWH sales in 2023 totaled 190,000. Shattering all doubts, TVA’s success cemented a midstream program model’s ability to move markets on scale.

What truly worked for TVA EnergyRight was the program’s clarity. They simplified the process; instant discounts, minimizing administrative burden and maintaining consistent engagement with distributors and contractors throughout the program

Rebate amount being reduced to $900 on February 15

To ensure the program’s longevity and stretch available funding through the remainder of the year, TVA is adjusting the rebate structure.

Effective February 15, 2026:

• The rebate amount for qualifying Heat Pump Water Heaters (HPWHs) will be $900 per unit.

• To qualify for the current $1,300 rebate, units must be sold by February 15, 2026, and reported no later than March 20, 2026.

TVA is continuing to build on this momentum, engaging with distributors and retailers, focusing on expanding inventory, strengthening supplier and distributor relationships, training contractors, and educating homeowners about the benefits of HPWHs through newsletters, blogs, and other outreach tools.

With streamlined processes and a commitment to a more energy efficient future for the Tennessee Valley residents, TVA has exceeded its original expectations for HPWH adoption. What began as a 4000 HPWH installation goal scaled into an exceptional market shift driven by a simplified process. TVA EnergyRight has proved that HPWH growth can be vastly accelerated with strong rebates and smart programs.
