Rate Schedules & Tariff Analysis

Columbia Gas of Kentucky C&I rates separate the regulated distribution (delivery) charge from the Gas Cost Adjustment commodity pass-through. Firm commercial/industrial customers default to GSO, which uses a declining-block delivery charge that rewards higher volume. Very large loads can pursue interruptible service (IS) or move to transportation (DS) to procure their own gas — the principal lever for large-volume customers is supply procurement, since interval/demand-response options are limited by the lack of smart metering.

Columbia Gas of Kentucky Rate Schedule List

ScheduleApplicability
GSO — Commercial/Industrial$110.00 + declining-block delivery ($3.1581→$2.1078/Mcf) + GCA.
IS — Interruptible Service$5,000 + tiered delivery + $18.8406/Mcf firm demand.
IUS — Intrastate Utility Service$1,135 + $0.9198/Mcf base ($8.8038 total).
DS — Delivery ServiceTransportation for >25,000 Mcf/yr; customer procures own gas.

Columbia Gas of Kentucky Rate Features & TOU Details

Columbia Gas of Kentucky Data Access FAQ

Can a commercial customer get interval gas data from Columbia Gas of Kentucky?

No. Columbia Gas of Kentucky has not deployed AMI or smart meters, so only monthly usage (in Mcf) is available — there is no 15-minute, 30-minute, or hourly interval data and no API. C&I customers who need granular data typically install their own building-level metering or data loggers.

How does a consultant or aggregator access a customer's Columbia Gas data?

There is no Green Button or formal third-party authorization portal. The options are (1) shared portal credentials / secondary-contact access, or (2) a written customer authorization submitted to Customer Care (1-800-432-9345 or the Document Upload form), which returns PDF bills/usage by email in roughly 5-10 business days.

Does Columbia Gas of Kentucky support EDI?

No. Per the official Columbia Gas suppliers FAQ, the utility uses a proprietary flat-file data exchange rather than ANSI X12 EDI. The EFTP file exchange and Aviator nominations system are available only to gas suppliers (Customer Choice) and transportation customers (Delivery Service), not to standard residential or commercial accounts.

What rate schedule applies to a commercial or industrial gas customer?

Most non-residential firm customers take Rate Schedule GSO (General Service — Commercial or Industrial): a $110.00 monthly customer charge plus a declining-block delivery charge starting at $3.1581/Mcf for the first 50 Mcf, plus the Gas Cost Adjustment. Very large customers may qualify for Interruptible Service (IS) or Intrastate Utility Service (IUS), or move to transportation (Delivery Service) and buy their own gas.

Can a large customer buy its own gas supply?

Yes. Customers under 25,000 Mcf/year can use the Columbia Choice supplier program; customers over 25,000 Mcf/year can take Delivery Service (transportation) and procure gas independently, with nominations managed through the Aviator platform. Columbia Gas continues to own the distribution system and bill delivery charges in both cases.
