Texas Home Battery Payback Calculator (2026)
Priced on Retail choice (no default TOU) Flat (representative) rates and full-retail export rules. No federal tax credit is assumed — Section 25D ended 2025-12-31.
Why Texas is different
Texas is a battery state without a battery rate story. ERCOT's retail-choice market means your rate and export terms depend on which REP you sign with — there is no default TOU plan, so our model uses a representative flat rate of about 15.9 cents. Buyback plans credit exports at or near retail, which means storing solar does not cut the bill; the value is elsewhere. And elsewhere in Texas is serious: after Winter Storm Uri in 2021 left millions without power for days, whole-home backup moved from nice-to-have to the primary purchase driver, with summer heat close behind. VPP programs (Tesla's Texas VPP, Base Power, aggregators) add income but vary by provider — verify before counting on it.
Rate structure
| Rate | Value | Notes |
|---|---|---|
| Peak rate (discharge window) | $0.16/kWh · flat rate — same price every hour | |
| Off-peak rate (charging) | $0.16/kWh | |
| Export credit | $0.16/kWh · At or near retail (buyback plans vary) | |
| Average residential retail | $0.159/kWh · EIA statewide residential average 15.88¢ (2026-07) |
Verification status: Sourced. Representative flat rates (the EIA statewide average stands in)
Export mechanism: full-retail export
In Texas, At or near retail (buyback plans vary) — storing solar instead of exporting it does not reduce your bill. Custom rates that credit exports below retail flip this mechanism; turn on 'use my own electricity prices' in the calculator to model that plan.

Outage context
ERCOT weather outages are the primary driver of battery value in Texas
Typical payback in Texas
Precomputed with the same model as the calculator, at the Texas rates above and the reference installed cost of $12,000 (13.5 kWh usable, pre-incentive). Your numbers move with your bill, your quote and your rate plan.
| Scenario | Year-1 savings | Simple payback | 10-year net |
|---|---|---|---|
| Have solar · $200/mo bill · 13.5 kWh · $12,000 installed | $0 | — | −$12,000 |
| Have solar · larger bill · $600/mo bill · 13.5 kWh · $12,000 installed | $0 | — | −$12,000 |
| Battery only · $200/mo bill · 13.5 kWh · $12,000 installed | $0 | — | −$12,000 |

Frequently asked questions
How much can a battery actually save on my Texas bill?
On bill savings alone, the model's honest answer for a default Texas flat-rate plan is about $0: exports are credited at or near retail, so storing solar does not reduce your bill. The value case rests on backup power and VPP payments, which the results screen shows separately and never folds into the payback ratio.
Does Texas pay for home batteries?
Texas has no state battery rebate program Program terms change mid-cycle — verify on the program's own page before counting on any rebate.
Is a battery worth it in Texas without the federal tax credit?
Section 25D ended 2025-12-31, so every result on this site assumes no federal credit. That makes the break-even installed price the most useful number on the results screen: it is the price at which the ten-year arithmetic stops working at your assumptions. Compare every quote against it, and read the outage context above — backup is real value, just not a cash flow.
