Houston, TX 77251

Houston's 77251 zip code sits in the heart of Harris County — home to over 2.3 million residents and one of the most competitive electricity markets in Texas. Served by CenterPoint Energy (CNPT) for delivery infrastructure, this zip code is fully deregulated, meaning residents have genuine freedom to choose from 42 retail electric providers offering 192 plans as of March 2026. That level of competition is exceptional even by Houston standards, and it translates directly into meaningful savings opportunities for households across all income levels. With a median household income of $56,019 in Harris County, finding a rate that fits your budget matters — and the spread between the best available rate and the market average is wide enough that shopping actively can save hundreds of dollars annually.

Rate Landscape in Houston 77251 — March 2026

The most competitive rate currently available in the 77251 zip code is 7.9¢/kWh, offered through the GridPlus 12 plan from Chariot Energy. That's a significant discount compared to the market average of 13.0¢/kWh across all 192 available plans — a gap of more than 5 cents per kilowatt-hour. For a household using 1,200 kWh per month, that difference amounts to roughly $60 per month, or $720 per year. Rates in this area range broadly depending on contract length, provider, and plan structure, with fixed-rate plans (149 available) offering the most predictability heading into Houston's high-demand summer months.

Contract Strategy: Short, Medium, or Long Term?

Contract length plays a major role in what you'll pay in 77251. Short-term plans (1–6 months) currently average 11.5¢/kWh — surprisingly competitive and worth considering if you expect to move, want flexibility, or believe market rates may drop later in 2026. Medium-term plans (7–18 months) average 13.1¢/kWh, while long-term plans (19+ months) average 13.7¢/kWh. In this market, locking in a long-term deal doesn't automatically mean a better price — shorter contracts are outperforming longer ones right now. That said, if you find a standout fixed rate like Chariot Energy's 7.9¢/kWh on a 12-month term, locking it in before summer demand spikes is a smart move.

Provider Competition in 77251

With 42 providers actively competing for customers in this zip code, 77251 is among the most competitive electricity markets in Houston. Established names like TXU, Reliant Energy, Direct Energy, and Constellation Energy compete alongside value-focused providers like Gexa Energy, Frontier Utilities, and Payless Power, as well as green-energy specialists like Green Mountain Energy, Chariot Energy, CleanSky Energy, and Rhythm Energy. That diversity means consumers can prioritize price, renewable content, customer service reputation, or contract flexibility — rather than settling for a one-size-fits-all plan. Notably, 42 green or renewable plans are available, making 77251 a strong market for eco-conscious shoppers.

Local Market Context: How 77251 Compares

Rates and plan availability in 77251 are broadly consistent with neighboring Houston zip codes including 77001, 77002, 77003, 77004, and 77005, all of which fall within the same CenterPoint Energy service territory. However, plan-level pricing and promotional offers can vary slightly by zip code, so it's always worth checking rates specifically for 77251 rather than assuming a neighbor's plan applies. Houston's subtropical climate drives significant electricity demand from May through September, when cooling costs spike — making March an ideal time to lock in a competitive fixed rate before summer pricing pressure builds.
