Rate Recommendations by Use Case
Small/mid commercial facility
A typical commercial building (restaurant, small manufacturer, office) using under ~150,000 cf/month should be on General Service-Small (GSS-2099).
GSS pairs a low fixed charge ($39.30/mo Houston) with a moderate commodity rate (~$0.060/Ccf), which is cheaper than GSLV at lower volumes.
- Track average monthly usage to ensure you stay below the 150 Mcf/mo breakpoint
- Use My Account to monitor 24 months of usage and spot anomalies
- Watch the PGA line for gas-cost swings
Large commercial / industrial load
Facilities averaging more than 150,000 cf/month should take General Service-Large Volume (GSLV-630).
GSLV is the applicable schedule above the breakpoint; its higher customer charge is spread across large volumes. A written contract is required above 25 Mcf/day.
- Right-size your contract maximum daily quantity to avoid $10/Mcf over-run charges
- Compare GSLV vs. Rate T transportation if you can procure your own supply
- Use CES Online for multi-account invoice management
Very large industrial user evaluating supply choice
Very large-volume industrials should evaluate Transportation Service (Rate T) and self-procured gas supply.
Buying gas directly and paying CenterPoint a delivery charge can beat the bundled PGA commodity rate for high, steady loads.
- Model delivered cost (supply + transport) vs. GSLV bundled rate
- Engage a qualified gas marketer/broker for supply
- Confirm metering and contract terms with CenterPoint
Multi-site portfolio / energy manager
Portfolios spanning multiple Geographic Rate Areas should centralize data access and account for area-specific rates.
Customer and commodity charges differ by rate area (Houston/Texas Coast vs. South Texas/Beaumont). Centralized access (Authorized Users or UHIT) streamlines monitoring.
- Use Authorized Users for portal access or UHIT API for programmatic pulls
- Normalize usage to Ccf across sites
- Track per-area rate differences in your cost model
Historical Rate Trends
CenterPoint Entex base rates are reset in RRC rate cases (e.g., GUD OS-23-00015513) and adjusted annually through the GRIP (Gas Reliability Infrastructure Program) rider, which steps up the customer charge each year.
January 1, 2026
2026 GRIP rider added to customer charges (e.g., +$55.20 on GSLV Houston/Texas Coast, +$4.18 on GSS), reflected in the GRIP 2026 rate sheets.
GRIP rider step-upJanuary 1, 2025
2025 GRIP rider added to customer charges (e.g., +$60.89 on GSLV, +$5.12 on GSS) per Case 00020313.
GRIP rider step-upOverall trend: Rising. Customer charges have increased via successive GRIP riders — for example, GSLV adds a 2025 GRIP charge of $60.89 and a 2026 GRIP charge of $55.20 on top of the $390.00 base (Houston & Texas Coast), reaching the current $506.09 total customer charge.
Next expected change: Next annual GRIP rider adjustment (typically filed/effective each year); future base-rate change subject to the next RRC rate case.
Cost Optimization Strategies
Because CenterPoint Entex gas rates are regulated and largely volumetric plus a fixed charge, C&I optimization focuses on rate-schedule selection, demand/usage management, and verifying pass-through adjustments rather than supplier shopping.
Confirm correct rate schedule (GSS vs. GSLV)
For: All C&I gas accounts
The GSS/GSLV breakpoint is 150,000 cf/month average. Sites near the threshold should model both schedules — GSLV's high fixed charge plus higher commodity rate is not always cheaper than GSS.
Evaluate transportation service for very large loads
For: Large industrial users (well above 150 Mcf/mo)
Very large-volume users may benefit from Rate T transportation service by procuring their own gas supply and paying CenterPoint a delivery-only charge.
Audit PGA and rider pass-throughs
For: All C&I gas accounts
The Purchased Gas Adjustment and GRIP/tax riders move independently of base rates. Track them to validate bills and forecast cost.
Manage usage and avoid over-run charges
For: GSLV customers with written contracts
On GSLV, deliveries over the contract's maximum daily quantity incur unauthorized over-run charges ($10.00/Mcf plus the monthly rate). Right-size contract quantities and manage peak days.

Deregulated Market Shopping
Texas natural gas distribution is regulated; there is no residential-style retail gas-supplier choice in the Entex territory. The closest analog for large customers is Transportation Service (Rate T), under which a qualifying large-volume customer arranges its own gas supply (often through a marketer) and pays CenterPoint a regulated delivery charge.
How to Compare CenterPoint Energy Entex (Texas Gas) Suppliers
- 01Confirm eligibility for transportation service based on volume
- 02Solicit gas supply offers from licensed marketers/brokers
- 03Model delivered cost (supply + CenterPoint transport) vs. bundled GSLV
- 04Execute a transportation/delivery agreement with CenterPoint
Contract Terms for CenterPoint Energy Entex (Texas Gas) Supply Agreements
- Written contract required for deliveries above 25 Mcf/day
- Maximum daily quantity and over-run provisions apply
- Supply contract term and pricing negotiated with the marketer
Common Pitfalls When Shopping CenterPoint Energy Entex (Texas Gas) Rates
- Unauthorized over-run gas is billed at $10.00/Mcf plus the monthly rate
- Transportation does not eliminate the fixed customer/delivery charge
- Most small and mid-size customers are not eligible and remain on regulated GSS/GSLV
Frequently Asked Questions
Can my business get interval (hourly/15-minute) gas usage data from CenterPoint Entex?▾
No. Natural gas service in the Entex Texas territory provides monthly usage (in Ccf) only. CenterPoint's Itron smart gas meters are read monthly, and there is no public interval-data feed for gas as there is for electric service.
How does a large C&I gas customer access billing data?▾
Large commercial and industrial customers use CES Online. Complete the CES Online Access Request Form with your company and account details; CenterPoint typically issues credentials within 1-2 business days, after which you can view invoices, manage multiple accounts, and receive notifications.
How can a consultant or aggregator pull our usage programmatically?▾
Through the Usage History Inquiry Tool (UHIT) REST API. With signed customer authorization, register with CenterPoint Competitive Retailer Relations (cr.support@centerpointenergy.com), accept the terms of use, and query historical monthly usage in XML/JSON.
Is the Texas gas market deregulated?▾
Gas distribution is regulated by the Railroad Commission of Texas; small and mid-size customers are billed on regulated rate schedules. Very large-volume transport-eligible customers can negotiate written transportation contracts, but there is no residential-style retail gas choice in the Entex territory.
What rate schedule applies to my business?▾
Commercial/industrial accounts averaging 150,000 cubic feet/month or less take General Service-Small (GSS); accounts averaging more than 150,000 cubic feet/month take General Service-Large Volume (GSLV). Both have area-specific customer and commodity charges plus periodic GRIP, PGA, and tax adjustments.
