Houston metro bill outlook · 2026 edition
Why Your Houston Electric Bill Could Hit a Record in 2026
Four things are pushing your bill at the same time. Hotter summer. Tighter grid. Eleven percent demand growth. Higher rates already locked in. Texas residential rates already jumped from about 11.7¢/kWh in 2020 to 15.56¢/kWh last year. ERCOT expects another 11% demand surge this year on top of that. This page lays out what's coming, where the numbers come from, and the one lever you actually control.

The four forces hitting your 2026 bill
- Heat. NOAA's April 16, 2026 seasonal outlook favors above-normal temperatures across most of the contiguous U.S. for May through July, with a 61% chance of El Niño emerging by mid-summer and persisting through year-end.
- Grid. ERCOT's December 2025 Capacity, Demand and Reserves report puts the summer 2026 reserve margin at 18.3% at the peak load hour. The same report warns that summer reserve margins cross over to negative values by 2028.
- Demand. The U.S. Energy Information Administration projects ERCOT electricity demand will grow 11% in both 2025 and 2026, more than any major U.S. grid region. Data centers and AI drive most of the new load.
- Rates. Texas residential electricity rates rose roughly 33% from 2020 to 2025. CenterPoint customers face an additional $4-plus per month from 2025 distribution rate actions already approved by the Public Utility Commission of Texas.
Heat plus grid plus demand plus rates. One force was a manageable problem. Four at once is the math behind a record bill.
How much have Texas electric rates already risen?
A lot. Here's the EIA primary data, residential customers only, statewide average.
| Year | TX Residential ¢/kWh | YoY change | Source |
|---|---|---|---|
| 2020 | ~11.7 | — | EIA EPM 5.6.B |
| 2021 | ~12.85 | +9.8% | EIA EPM 5.6.B |
| 2022 | ~13.76 | +7.1% | EIA EPM 5.6.B |
| 2023 | ~14.32 | +4.1% | EIA EPM 5.6.B |
| 2025 (annual avg) | 15.56 | +8.7% vs 2023 | EIA EPM 5.6.B |
| Feb 2026 | 15.41 (single mo) | +3.6% vs Feb 2025 | EIA EPM 5.6.A |
Two caveats worth saying out loud. First, this is the residential rate. The Texas all-sectors blended average is around 10¢, because industrial buyers get bulk pricing you don't. Second, Texas runs a deregulated retail market, so the 15.41¢ figure is a state-wide average. Your specific retail provider's plan can be higher or lower.
Why is the rate rising in a deregulated market? Three reasons. Distribution charges (the delivery side) are still regulated and going up. The generation mix is shifting, with coal and gas plants retiring faster than wind and solar add capacity. And demand is outpacing supply, which the EIA Texas Electricity Profile 2024 confirms: Texas is the #1 electricity-consuming state in the country at 505 million MWh in retail sales last year.
What is NOAA saying about summer 2026?
The Climate Prediction Center's April 16, 2026 long-range outlook favors above-normal temperatures across most of the lower 48 states for May through July. There's a 61% probability that El Niño will emerge during that same window and persist through the rest of 2026, peaking around October-December at +1.2°C, which qualifies as a moderate El Niño event.
Houston specifics. We're in a humid subtropical climate. August is the hottest month, with an average high of 95°F based on the 1991-2020 NOAA Climate Normals. Annual precipitation averages 49.77 inches across 104 days. The 2023 Texas summer set the ERCOT all-time peak demand record at 85,435 MW on August 10. That's the anchor for what a hot summer actually looks like on the grid.
Houston falls within the broad above-normal-favored region in the NOAA outlook. The agency publishes an updated specific probability map for the Houston grid cell each month. See the current outlook at the NOAA CPC Long Range page.
How tight is ERCOT's grid for summer 2026?
Tighter than the headline number suggests, and the trend is the real story.
| Period | Summer Planning Reserve Margin | Source |
|---|---|---|
| Summer 2024 (May 2024 CDR) | 38.2% with new contracted loads | ERCOT CDR May 2024 |
| Summer 2026 (Dec 2024 CDR) | -6.2% net peak / +5.2% peak load | ERCOT CDR Dec 2024 |
| Summer 2026 (Dec 2025 CDR, refined) | +18.3% peak load hr / +20.9% net peak | ERCOT CDR Dec 2025 |
| Summer 2028 forecast | NEGATIVE | ERCOT CDR Dec 2025 |
ERCOT's board target is a 13.75% minimum reserve margin, set under PUCT Project 42302. So 18.3% looks fine on paper. But two things matter underneath.
First, the methodology shifted hard. Texas House Bill 5066 (2023) requires the Public Utility Commission to consider transmission service provider attestations of new data-center load. When ERCOT folded those attestations into the December 2024 CDR, the projected summer 2026 margin dropped to negative. The December 2025 number recovered to +18.3% only because ERCOT refined assumptions about how those large loads behave during emergencies, not because the load went away.
Second, the pipeline keeps growing. ERCOT reports 226 GW of large loads sought interconnection as of November 18, 2025, up from 63 GW one year earlier. Data centers are about 73% of those requests. ERCOT projects data-center demand alone will exceed 22,000 MW by 2030, up from a 2,400 MW forecast for 2026.
The Monthly Outlook for Resource Adequacy (MORA) for July 2026 puts the peak hour load at 74,569 MW, with a 41.3% capacity reserve margin and a 0.21% probability of an Energy Emergency Alert at the highest-risk evening hour. See the ERCOT Resource Adequacy hub and the MORA July 2026 PDF for the full assumption set.
For context: 2023 had 13 conservation requests and one EEA Level 2 event on September 6, when operating reserves dropped below 1,750 MW. 2025 was a mild Texas summer (June 2025 was the 28th hottest in 131 years of records). 2026 is trending hotter with 11% more load on the system.
What's CenterPoint Energy charging now?
A lot more than two years ago. CenterPoint Energy Houston Electric is the regulated wires company for Pasadena and the broader Houston metro. Their distribution charges flow through to whatever retail provider sends your bill.
| Date | Action | $ Impact (1,000 kWh customer) | Source |
|---|---|---|---|
| Feb 2024 | 2024 Rate Case filed (PUCT Docket 56211) | — | PUCT Interchange |
| Jan 2025 | Rate Case settlement | -$1/mo for typical customer | CenterPoint |
| Apr 2025 | DCRF approval | +$2.22/mo | PUCT |
| Sep 2025 | Distribution rate increment effective | +1.35¢/kWh | PUCT filing |
| Oct 2025 | Storm-cost recovery rider (Beryl, derecho, Jan 2025 winter storm) | +$2/mo for 15 years | PUCT |
For a typical 1,000 kWh per month customer, that's roughly $4-plus per month in 2025 actions alone, before the higher per-kWh rate kicks in during summer when consumption doubles. Cumulative storm-recovery and rate-action approvals across CenterPoint's territory total around $1.2 billion in regulatory recovery over the multi-year amortization windows.
The full filing history sits at PUCT Docket 56211 on the Public Utility Commission of Texas Interchange.
How does this all add up to YOUR bill?
Walk it through with a real number. Take a 1,000 kWh per month CenterPoint customer, the benchmark used in the rate case settlement.
- 2024 bill at ~14.32¢/kWh (TX residential average): about $143/mo
- February 2026 rate, 15.41¢/kWh: $154. That's already +$11/mo, +7.7%
- Add the ~$4/mo CenterPoint distribution increases: $158
That's the average month. The summer surge is the real bill story.
A typical Houston home uses 1,500 to 2,200 kWh in July and August because of cooling load. Multiply 1,750 kWh by 15.41¢ and you get $270/mo in July. Multiply 2,200 kWh and you get $339. That's before any 2026 mid-year rate moves and before any grid emergency events that push retail providers to invoke higher peak pricing.
For homes with worse insulation (1980s and 1990s builds, R-19 attic, original ductwork) summer consumption can climb to 2,500 to 3,000 kWh per month:
- 2,500 kWh × 15.41¢ = $385/mo
- 3,000 kWh × 15.41¢ = $462/mo
A worst-case under-insulated 1980s Pasadena home with a 4-ton AC running constantly can reach $400 to $550 per month in July and August, before any further 2026 rate increases.
These are upper-band scenarios. Your specific home could be much lower. The point isn't that everyone hits $500. The point is the cushion against "wait and see" shrinks fast when four forces push the same direction. And replacing a failing 4-ton AC system in 2026 runs $9,000 to $15,000, which is more than a typical attic spray foam job.
What can a homeowner actually control?
Three levers. Honest about the size of each.
1. Switch retail provider
Free, takes 15 minutes on PowerToChoose.org. Saves 1 to 3¢/kWh if you're sitting on a default plan. Doesn't address rising rate trends or peak-hour risk. Small lever, worth pulling first because it costs nothing.
2. Reduce consumption
This is the big lever for Houston. Spray foam insulation in Pasadena typically cuts summer AC consumption 20-40% in older Houston homes by stopping the conductive heat load through the attic and the air leakage that pulls hot air into the conditioned space. Upgrading attic insulation in Pasadena is the single highest-impact move for most pre-2000 homes. AC tune-ups and smart thermostats add a few percent each. One-time investments, decoupled from rate volatility going forward.
3. Shift behavior
Pre-cool the house before 4 p.m., delay big appliance use until after 9 p.m. Free, takes daily attention. Helps during conservation alerts. Doesn't move the average bill much.
Why insulation is the consumption-hedge play. Rates go up. Your kWh use stays fixed unless you change the building. Bill goes up. Insulate the attic and you use fewer kWh regardless of where rates land. During grid stress events, you're using less of the strained capacity, which protects against peak-pricing exposure.
The federal incentive picture changed in 2025. The CenterPoint Energy rebate is the material 2026 program: up to $750 for all-electric homes or $450 for gas-heated homes, approved-contractor installations, R-11 to R-38 minimum upgrade. See our breakdown of Pasadena spray foam cost ranges and the CenterPoint rebate details for current pricing.
What about the federal tax credit you've been hearing about?
Section 25C, the Energy Efficient Home Improvement Credit, was terminated for property placed in service after December 31, 2025. The change came from Public Law 119-21, the One Big Beautiful Bill Act, signed July 4, 2025.
If you installed insulation in 2025, you can still claim 30% of qualifying material costs up to $1,200 on your 2025 federal return using Form 5695. That window closes when you file.
If you install in 2026, you cannot claim Section 25C. The 2032 sunset that the Inflation Reduction Act of 2022 had originally scheduled is gone. The IRS published the official guidance at the FAQ on Public Law 119-21 modifications.
The 2026 incentive picture is the CenterPoint rebate plus any current Texas State Energy Conservation Office programs (these change yearly). Confirm specific dollar amounts before relying on them. A lot of contractor websites still quote the old 25C rules, which is wrong for 2026 work.
When is the next conservation alert likely?
ERCOT's emergency alert risk peaks between 4 and 9 p.m. Central during August heat waves. Solar generation ramps down in the evening while residential and commercial load stays high. Cryptocurrency miners ramp back up. The MORA July 2026 report puts the highest-risk hour at 9 p.m. Central.
Recent track record:
- 2023 had 13 conservation requests across the year and one EEA Level 2 on September 6, when operating reserves fell below 1,750 MW
- 2024 had a winter conservation appeal during the January cold front
- 2025 was a mild summer with only routine alerts
Reasonable expectation for 2026: at least 2 to 5 conservation requests this summer if NOAA's hot-summer forecast verifies and load grows as projected. Better-insulated homes use less in those peak hours regardless of how many alerts ERCOT calls.
How alerts work for you. ERCOT issues conservation requests through your retail electric provider, often by text. The ask is voluntary: raise the thermostat 2-3°F, delay big appliance use. If reserves keep dropping, EEA Level 1 fires below 2,500 MW, Level 3 (controlled outages) at 1,500 MW.
