Cirro Energy’s Flattest Plan Beats Its Own “Simple” One — All 9 Houston Plans at 500, 1,000 and 2,000 kWh, and a 62% Billing-Complaint Share (Sept 2026)

Cirro Energy sells itself on simplicity, and on nine of its Houston plans that promise mostly holds up. On September 10, 2026, Cirro Energy priced between 13.9¢ and 20.9¢ per kWh at ZIP 77002 depending on plan and usage, and its two flattest plans moved less than a cent between 500 and 2,000 kWh. The exception is the pair of Bill Bonus plans, where a $125 or $150 credit swings the average price by 13 cents. Below is every Cirro Energy plan at all three usage levels, the NRG ownership picture, and the one number in Cirro’s PUCT complaint record that stands out from every other Texas provider.

What is Cirro Energy?

Cirro Energy is a retail electricity provider that sells only in deregulated Texas. Legally it operates as US Retailers LLC under PUCT certificate #10177, and it is one of NRG Energy’s four residential retail brands in the state; NRG’s own broker transition materials list Cirro alongside Reliant, Green Mountain Energy and Direct Energy Business. Cirro’s About page describes a Texas-based company that has run on “fair prices, simple plans, no surprises” for over 20 years, which puts its founding in the early 2000s, shortly after Texas deregulated retail electricity in 2002.

That shared parent matters when you shop. Cirro Energy, Reliant, Green Mountain and Direct Energy compete for the same Houston and Dallas customers with different plan designs, different websites and different call centers, but the same corporate hedging desk behind them. Switching between NRG brands changes your rate and your bill format; it does not change who ultimately supplies your power. Cirro’s role in that lineup is the no-frills one: the smallest plan card of the four, no renewable premium tier, no rewards program, and a website that shows all three usage prices at once instead of making you toggle.

Cirro Energy plans and rates in Houston (September 10, 2026)

These are all nine plans Cirro Energy displayed for ZIP 77002 (CenterPoint Energy delivery area) on September 10, 2026. Cirro publishes 500, 1,000 and 2,000 kWh prices on every plan card simultaneously, which is unusually transparent for a Texas REP — most providers show one usage level and make you change a filter. Prices are Cirro’s own displayed average price per kWh and include CenterPoint delivery charges; taxes are extra. Oncor, AEP Texas and TNMP addresses will differ by the delivery charge.

Which Cirro Energy plan is cheapest for your home?

If your usage reliably clears 1,000 kWh every single month, Bill Bonus 9 at 7.9¢ is the cheapest thing Cirro Energy sells and one of the lowest 1,000 kWh prices in Houston. The catch is the same one every credit plan carries: at 500 kWh it prices at 20.9¢, so a single mild month costs you roughly what two months of savings earned. And note the shape — Bill Bonus 9 is 13.9¢ at 2,000 kWh, worse than at 1,000, because a fixed $125 credit spread over twice the kilowatt-hours is worth half as much per kWh. It is a plan tuned for one specific meter reading.

Bill Bonus Saver 18 is the same idea moved up a level: 11.9¢ at 2,000 kWh on a $150 credit, but 20.2¢ at 500 and 19.7¢ at 1,000. A 2,000 kWh household is usually a large home with central air, and those homes swing hardest between August and March, which is exactly the wrong profile for a threshold plan. Run your own 12 months of usage before you take either Bill Bonus.

For everyone else the answer is Smart Nights 24, and it is the most interesting plan on Cirro’s card. At 15.7¢ / 15.2¢ / 14.9¢ it moves eight tenths of a cent across the entire range — flatter than Direct Energy’s Live Brighter, flatter than Amigo’s Weekends Free — and it undercuts Cirro’s own Smart Simple 24 at every usage level while locking for the same 24 months. The night discount from 8 p.m. to 8 a.m. is a bonus on top of an already competitive flat rate rather than the whole pitch, which is the opposite of how most time-of-use plans in Texas are priced. Smart Lock Saver 9 ties it at 1,000 kWh and beats it at 2,000, so a high-usage household that wants a short term has a real alternative. Skip Smart Lock Saver 12 (a full cent above the 9 at 500 and 1,000 for no benefit), skip Smart Nights 12 (worse than the 24 everywhere), and treat Smart Flex 2000 as a bridge plan for a short stay, not a place to sit.

Cirro Energy’s PUCT complaint record (March–August 2026)

The Public Utility Commission of Texas publishes informal complaint counts by provider and category. Here is Cirro Energy’s six-month record next to the other large REPs, pulled from the PUCT’s Customer Complaint Statistics page on September 10, 2026. These are raw counts, not rates: the PUCT does not publish customer totals alongside them, so a provider with more customers will naturally log more complaints.

Source: PUCT Customer Complaint Statistics, Retail Electric Providers, 3/1/2026–8/31/2026 (summary generated 9/10/2026). Cramming and “all other” columns omitted (Cirro Energy: 0 and 0). Billing share is billing complaints divided by that provider’s total, calculated by myutilitysearch.com. Counts are not normalized by customer count.

Cirro Energy’s total of 138 puts it mid-pack, tied with Just Energy and well below Reliant’s 340. The number worth reading is the mix. Across all Texas REPs, 49% of informal complaints are about billing. For Cirro Energy it is 62% — 85 of 138 — the highest billing share among the eight large brands, and eleven points above its own sister brand Direct Energy. Cirro’s slamming and discontinuance numbers are unremarkable, which suggests the issue is not how customers are signed up or cut off but what happens on the invoice afterward. For a provider whose entire pitch is “one combined bill line” and “no surprises,” that is the category you would least want to lead. Two of its nine plans are threshold-credit plans, and a credit that does or does not appear is exactly the kind of thing that generates a billing complaint.

Is Cirro Energy a good electricity provider?

For a household that wants a flat, boring, competitive rate and no math, yes. Smart Nights 24 is one of the best-shaped plans we’ve priced in Houston this month: cheapest-in-class at 500 kWh, within a rounding error at 1,000 and 2,000, no threshold to miss, and a night discount thrown in. Cirro Energy also publishes all three usage prices on the plan card without making you hunt for a filter, which is a genuine consumer courtesy and rare in this market. Its weaknesses are a thin nine-plan card with no renewable option, a variable plan (Smart Flex 2000) that is expensive below 2,000 kWh, two bill-credit plans that behave like every other bill-credit plan, and a billing complaint share well above the market. If you value the lowest possible number at exactly 1,000 kWh, Amigo Energy’s 7.0¢ and Cirro’s own Bill Bonus 9 at 7.9¢ are in the same tier; if you value a bill that reads the same every month, Cirro Energy is a better answer than most of its NRG siblings.

How to sign up for Cirro Energy (and what to check first)

1. Compare Smart Nights 24 against Smart Simple 24 first. They lock for the same term, and Smart Nights was cheaper at all three usage levels on September 10. There is no reason to pay more for the “simple” label.
2. Only take a Bill Bonus plan if you have 12 months of usage in hand. Pull it from Smart Meter Texas or your old bills. If any month in the last year fell below the threshold, the credit plan probably costs you money.
3. Read the EFL for the usage charge, not just the base charge. Cirro’s Smart Simple and Smart Flex plans advertise no usage charge; the others may carry one below a threshold, and that is what makes the 500 kWh column jump.
4. Check the term against your lease or move date. Cirro sells 9-, 12-, 18-, 24- and 36-month locks plus a month-to-month; early termination fees apply on the fixed terms, and Texas law waives the fee only if you move somewhere Cirro can’t serve.
5. Save the enrollment confirmation and check your first two invoices. Given the billing complaint pattern, confirm the rate, the credit and the delivery charges on the bill match the EFL before the third cycle.

Cirro Energy for business: Smart Lock, Smart Flex and Smart Flex Index

Cirro Energy, an NRG retail brand, is one of the few Texas suppliers that names its business products. As of September 28, 2026 it sells three: Smart Lock Business, a fixed price for the whole term with terms from 3 to 60 months and a cancellation fee; Smart Flex Business Index, priced to the market with an option to lock in, where eligibility varies by location; and Smart Flex Business, a no-commitment plan on which the rate adjusts monthly and the customer “can change plans or change providers at any time without penalty.” No rates are published; quotes come through the commercial portal. Because Cirro is an NRG brand, NRG Business’s published Texas small-commercial terms are the closest public reference for the base charge, pass-through and exit fee — and Champion’s public 9.7¢ energy charge on Oncor is the price to beat.

What a commercial contract adds over the residential plan on this page: a price built from your meter’s 12-month usage and load factor rather than a published rate card, term choices from 12 to 36 months or longer, a base charge and pass-through structure that differ from the residential EFL, and exit terms that scale with the months remaining.
