Rate Recommendations by Use Case
Small/general commercial customer
Standard commercial customer on bundled sales service.
Rate 220 bundles delivery and gas supply with the quarterly GCA, the simplest option for general commercial loads that do not meet the 25,000 therm/yr transportation threshold.
- Track therms and GCA changes through My Account.
- Add an authorized user for your energy consultant.
Larger commercial / mid-size facility
Higher-volume general-service customer.
Larger general-service sales customers fall under Rate 240; review whether annual volume approaches the 25,000 therm transportation threshold where Choice becomes available.
- Benchmark usage via the Energy Data Portal / ENERGY STAR if available.
- Model transportation savings as volume grows.
Large industrial / transportation-eligible customer
Non-residential customer using >=25,000 therms/year that can buy its own gas.
Transportation service lets large customers procure gas from an approved supplier and pay CenterPoint delivery only, often beating bundled commodity cost. Rate selection depends on volume and contract term.
- Compare quotes from approved suppliers (Constellation, Symmetry, CIMA, Kinetrex, NRG).
- Use the Gas Tracking System for nominations, usage, and settlement.
- Confirm consolidated vs. dual billing in the agency agreement.
