What is a “TVA-preferred air source heat pump”?

A TVA-preferred air source heat pump is any heat pump that meets certain minimum standards for energy efficiency. In addition to replacing an existing electric heat source, a new, all-electric heat pump must have a minimum SEER2 rating of 15.2 for cooling and an HSPF2 rating of 8.1 for heating. It must also have a variable speed compressor (excluding two-stage compressors), and the system should produce 100% of rated heating capacity without backup heat at 17 degrees outdoor temperature. Cooling capacity cannot exceed 125% of cooling load at design conditions. The system must be installed by a manufacturer-certified installer who participates in our Quality Contractor Network. And finally, the installer must provide a Manual J Calculation 8th edition with their project submission in order to qualify for EPB and TVA EnergyRight® Home Energy Rebates. EPB Energy Pros can help you better understand these requirements.

For current Solar Share participants: Charges will appear the month after you sign up with credits appearing the month after that. For example, if you contact EPB and sign up on July 15 for a panel, you will see the CHARGE on your AUGUST invoice (the next month and all following months). The CREDIT will appear on your SEPTEMBER invoice (approximately 2 months after you sign up and all following months). Why? During the first month after your purchase, your panel is generating electricity. That generation is accumulated throughout the month and then credited on your next bill. If a customer opts for the multi-year license, this is a one-time only charge.

For current Solar Share participants: Each solar panel within the array is estimated to produce approximately 37 kWh per month. Determine the percentage of your business's energy use you want to receive as a solar credit and multiply that by your average monthly energy use. For example, if you want 25% of your company's power use to be solar, and your average use is 1,600 kWh per month, you would license 11 panels (1600 x .25 = 400/37 = 10.8).
