Corpus Christi Gas Division Rate Selection Guide
Corpus Christi Gas Division is the City of Corpus Christi's municipal natural gas utility, serving 57,512 customers inside the city limits and surrounding environs on an Infor Public Sector billing system. Data access is portal-and-paper: a Municipal Online Payments portal for bills and payment history, manual third-party requests governed by Texas Utilities Code § 182.052 confidentiality rules, and no AMI, Green Button, API, or EDI capabilities.
Market Overview
Corpus Christi Gas Division is a municipal utility whose rates are set by city ordinance and council vote rather than commission proceedings. The Texas Railroad Commission has jurisdiction only over environs (outside-city) rate areas; rates inside city limits are governed entirely by municipal ordinance. There is no retail gas choice for CCGD customers.

Current Rate Schedules
Corpus Christi Gas Division sets rates by city ordinance and council vote rather than Texas Railroad Commission tariff (the RRC regulates only the environs areas outside city limits). The current rate structure dates to June 1, 2021, when the city restructured rates after Winter Storm Uri: the residential minimum charge rose to $18.60/month with the first 2 MCF included, and consumption above that bills as straight volume charges (around $2.25/MCF base) rather than declining blocks — plus the pass-through cost of gas, which spiked from ~$4 to over $100/MCF during Uri and drives most bill volatility. Separate rate sheets apply Inside City Limits and Outside City Limits (Environs), and the city publishes distinct General Customer (commercial/industrial) and Incentive Air Cooling & Conditioning schedules. See the city's published rate PDFs for current meter charges and MCF pricing tiers.
Effective: June 1, 2021 · Full Tariff Book →
| Schedule | Type | Applicability | Structure | Rate |
|---|---|---|---|---|
| General Customer Gas Service (Commercial/Industrial, ICL) | commercial | Commercial and industrial gas customers inside city limits — restaurants, hotels, laundries, process heat | Meter charge sized to service plus per-MCF volume charges and the monthly pass-through cost of gas. Rates set by city ordinance; see the General Customer Rates section of the city's gas rate PDF for current charges. | — |
| General Customer Gas Service (Environs / Outside City Limits) | commercial | Customers in unincorporated environs areas served by CCGD outside city limits | Parallel rate sheet with higher meter and volume charges than inside-city service; environs rates fall under Texas Railroad Commission jurisdiction. See the Outside City Limit rate document for current figures. | — |
| Incentive Air Cooling & Conditioning Rate | commercial | Customers operating natural gas air cooling/conditioning equipment | Discounted incentive pricing to encourage gas cooling load, which improves the system's summer load factor. Qualification and current rates per the city's rate schedule — contact utility billing at (361) 826-2489. | — |
Rate Recommendations by Use Case
Restaurants, hotels, and hospitality with steady gas load
Coastal Bend hospitality businesses on the General Customer schedule should focus on the pass-through cost of gas, which dominates bill variability under the post-Uri volumetric structure.
Since the 2021 restructuring moved CCGD to straight volume charges plus gas cost pass-through, there is little rate arbitrage between usage tiers — the levers are consumption efficiency and winter price exposure. Uri demonstrated that the commodity component can multiply 25x in a single week.
- Track the monthly cost-of-gas line on bills separately from the city's base charges
- Budget winter months conservatively — the commodity pass-through is unhedged at the customer level
- Verify your meter charge matches actual service size; oversized meters carry higher fixed costs
Industrial process heat and large boiler loads
Large industrial gas users in Corpus Christi's port-adjacent industrial corridor should engage the Gas Division directly on rate classification and service sizing.
CCGD publishes a single General Customer class rather than graduated industrial tiers, so large loads should confirm with the utility billing office whether contract or negotiated arrangements apply, and whether inside-city vs environs siting changes the applicable rate sheet and regulator (city council vs RRC).
- Call utility billing at (361) 826-2489 to confirm classification before committing to load additions
- Compare ICL vs environs rate sheets if siting flexibility exists — jurisdiction and pricing differ
- For very large loads, evaluate bypass/transport alternatives available in the Texas intrastate market
Facilities considering gas cooling or summer load
The Incentive Air Cooling & Conditioning rate rewards facilities that add summer gas load — unusual among municipal gas utilities.
Gas distribution systems are winter-peaking; CCGD discounts gas used for cooling to flatten its annual load curve. Facilities running gas absorption chillers or desiccant systems can capture below-standard pricing on that load.
- Confirm equipment eligibility and metering requirements with the Gas Division before installation
- Model gas cooling economics against electric chiller costs on AEP Texas/retail electric rates
- Combine with the General Customer schedule analysis for total facility optimization
Cost Optimization Strategies
As a gas-only municipal utility with a volumetric rate design and full commodity pass-through, CCGD cost optimization centers on managing the cost-of-gas exposure that Winter Storm Uri exposed, right-sizing fixed charges, and using the city's incentive cooling rate. There are no demand charges or TOU periods to arbitrage — consumption efficiency and winter risk management do the work.
Cost-of-gas tracking and winter exposure management
For: All commercial and industrial customers
The pass-through commodity charge is the largest variable on a CCGD bill — Uri pushed it from ~$4 to over $100/MCF in one week, and the city is amortizing that debt over 7-10 years. Track the monthly cost-of-gas factor, weight winter budgets accordingly, and consider reducing February gas dependence (thermal storage, dual-fuel capability) for critical operations.
Consumption efficiency on volumetric rates
For: All gas customers
Because the 2021 restructuring bills straight volume charges with no declining blocks, every MCF saved earns the full marginal rate plus the commodity pass-through. Boiler tune-ups, steam trap maintenance, heat recovery, and pipe insulation pay back directly with no rate-structure complications.
Incentive cooling rate enrollment
For: Facilities with or considering gas cooling equipment
Facilities with gas absorption chillers, desiccant dehumidification, or other gas cooling equipment can qualify for the city's Incentive Air Cooling & Conditioning rate, capturing discounted pricing on summer load that helps the utility's load factor.
Meter and service right-sizing
For: Commercial accounts with changed load profiles
Fixed meter charges scale with service size on the General Customer schedule. Facilities whose load has shrunk (equipment electrification, downsizing) should request a meter review so they aren't carrying capacity charges for unused service.
Rate ordinance monitoring
For: All customers
CCGD rates change by city council ordinance rather than commission filing, so changes can move faster and with less industry notice than RRC-regulated utilities. Monitor council agendas and the city's utility rates page; the current structure dates to June 2021 and Uri-debt surcharges will evolve as the 7-10 year recovery progresses.

Frequently Asked Questions
How do commercial customers access Corpus Christi Gas billing data?▾
Register at https://corpuschristitx.municipalonlinepayments.com/ with your account number and service zip code to view current bills, payment history, and account status, and generate PDF bills. For multi-year history (3-5 years is typical for energy analysis), submit a written request to the Utility Billing Office at (361) 826-CITY — expect PDF copies in 5-10 business days.
Does Corpus Christi Gas provide interval data?▾
No. There is no AMI deployment — gas meters are read and billed monthly, and no 15-minute, hourly, or daily data exists. Facilities needing granular load data should pull interval data from their electric utility instead; gas analysis must work from monthly MCF consumption on bills.
How can an energy consultant get a client's Corpus Christi Gas data?▾
Texas Utilities Code § 182.052 makes municipal utility customer data confidential by default. Have the customer complete a signed authorization (template from the Utility Billing Office) specifying account number, time period, and your firm as recipient, then submit it with a business description to (361) 826-CITY. Data arrives as PDF bill copies in roughly 5-10 business days — there are no ongoing feeds, so repeat the request each period.
Does Corpus Christi Gas support Green Button, an API, or EDI?▾
No to all three. The utility is not ESPI-certified, publishes no API or developer documentation, and has no EDI trading partner program (no 814/810/820/867 support). The Infor Public Sector CIS exposes no public integration surface. Nectar provides API access to this utility's billing data — see docs.nectarclimate.com.
Who sets Corpus Christi Gas rates?▾
The City Council, by ordinance — not the PUCT. Inside-city rates are pure municipal authority; the Texas Railroad Commission has jurisdiction only over environs (outside-city) rate areas. Current schedules (effective June 1, 2021) for inside and outside city limits are posted as PDFs on the city's utility rates page.
Can an aggregator or platform partner with Corpus Christi Gas?▾
Not through any existing utility program — there is no Share My Data mechanism or portal API. Platforms can serve individual CCGD customers via the manual § 182.052 authorization process, via Nectar's API (docs.nectarclimate.com), or propose a pilot program to the City of Corpus Christi Office of the CIO at 1201 Leopard Street for anything automated.
