Your electricity in zip code 77373 is delivered by CenterPoint Energy. Since this area is deregulated, you can choose your retail electricity provider while CenterPoint Energy maintains the power lines and handles outage restoration.
Spring, Texas residents in zip code 77373 are served by CenterPoint Energy's delivery network and have access to one of the most competitive retail electricity markets in the state. Located in Harris County — home to over 4.7 million residents and a median household income of $72,845 in Spring itself — this zip code benefits from full deregulation under Texas's choice electricity system. As of March 2026, 42 licensed retail electric providers (REPs) are actively competing for your business with 189 available plans, ranging from short-term flexible options to long-term fixed-rate contracts. With rates starting as low as 7.9¢/kWh, Spring 77373 shoppers have real leverage — but only if they know where to look and what to compare.
The most competitive rate currently available in the 77373 zip code is 7.9¢/kWh, offered through the GridPlus 12 plan from Chariot Energy. The average rate across all 189 available plans sits at 13.1¢/kWh — meaning savvy shoppers who compare before signing can potentially save over 5 cents per kilowatt-hour compared to simply picking a plan at random. For a household using 1,500 kWh per month, that gap translates to roughly $75 in monthly savings. Pricing in this area is shaped by wholesale power costs in the ERCOT Houston zone, seasonal demand (particularly summer cooling loads), and the high level of provider competition that keeps margins tighter than in less-contested markets.
March 2026 rate data for 77373 reveals an interesting pricing curve worth understanding before you sign:
For most Spring households, a short-term or carefully selected medium-term fixed-rate plan offers the best balance of savings and stability heading into the high-demand summer months.
The 77373 market is classified as HIGH competition — and that's a genuine advantage for consumers. Among the 42 active providers, you'll find nationally recognized names like TXU, Reliant Energy, Direct Energy, and Constellation Energy alongside Texas-focused providers such as Chariot Energy, Gexa Energy, Frontier Utilities, Rhythm Energy, Good Charlie, and Green Mountain Energy. This breadth of competition means providers regularly offer promotional rates, bill credits, and renewable energy options to win customers. Notably, 42 of the 189 available plans are green or renewable-backed — a strong selection for environmentally conscious households.
Regardless of which retail provider you choose, CenterPoint Energy (CNPT) remains responsible for the physical delivery of electricity to your home in 77373. Their regulated delivery charges — covering the poles, wires, and meter maintenance — are identical for every provider and every customer in this territory. You can reach CenterPoint at 1-800-332-7143 or centerpointenergy.com for outage reporting or delivery-related issues. To switch providers, simply contact your chosen REP with your ESIID number (found on your current bill). Switching is completely free, causes zero service interruption, and your new rate typically activates on your next scheduled meter read date.
Neighboring Spring zip code 77379 falls within the same CenterPoint delivery zone, so rate structures are broadly comparable across the Spring market. Spring's suburban growth, driven by proximity to The Woodlands corridor and major employment centers along I-45, keeps electricity demand steady year-round — with peak pressure arriving in June through August when cooling loads surge. Shopping or re-shopping your plan in late winter or early spring, as you're doing now in March 2026, is strategically smart: you lock in a rate before summer demand pushes wholesale prices higher.

Lock in a fixed-rate plan before May if your current contract is expiring — Spring's electricity demand surges from June through September, and wholesale prices historically climb as summer heat tightens grid capacity across the CenterPoint service territory.
Set your thermostat to 78°F or higher when away from home during Spring's summer months. Gulf Coast humidity makes indoor cooling expensive, and each degree of adjustment can reduce your cooling costs by approximately 3%, adding up meaningfully over a four-month summer.
Check whether your REP offers a free or subsidized smart thermostat program. Several providers serving Spring's zip codes partner with brands like Nest or Ecobee to help customers automate temperature schedules and reduce peak-hour consumption without sacrificing comfort.
If your Spring home was built before 2005, consider having CenterPoint-approved insulation or weatherization improvements done before summer — older Harris County homes often lose significant conditioned air through attics, which can add $30–$60 to monthly summer electric bills.
Compare both the energy charge (cents per kWh) and the base monthly fee when shopping plans in Spring. Some REPs advertise attractive per-kWh rates but carry $9–$15 monthly base charges that can erode savings, especially for smaller households using under 1,000 kWh per month.
As of March 2026, the most competitive rate in zip code 77373 is 7.9¢/kWh, available through the GridPlus 12 plan from Chariot Energy. The average across all 189 plans is 13.1¢/kWh, so comparing before enrolling can lead to significant savings.
