Rate Schedules & Tariff Analysis

Columbia Gas of Pennsylvania C&I bills separate the regulated distribution charge (PUC-approved) from the gas commodity, which can be bundled (sales service) or supplied competitively (distribution-only). The choice of schedule is driven primarily by annual throughput - the 64,400 therm/year threshold splits small from large general service - and by whether the customer shops for supply. Surcharges (STAS) and riders (PGDC, CAF, Universal Service Plan) layer on top of base distribution and customer charges.

Columbia Gas of Pennsylvania Data Access FAQ

Can a commercial customer choose their natural gas supplier with Columbia Gas of Pennsylvania?

Yes. Pennsylvania has a deregulated gas market. Under the PA Customer Choice program, commercial and industrial customers can buy the gas commodity from a licensed competitive supplier while Columbia Gas continues to provide distribution and billing. Compare offers against Columbia Gas's Price to Compare at PAGasSwitch.com before switching.

How does a C&I customer get historical usage data from Columbia Gas?

Commercial and industrial customers (and their authorized suppliers) can query historical usage through the Aviator-credentialed Historical Usage Portal at hdp.columbiasuppliers.com. Customers can also authorize a third party to receive billing and usage data using the Customer Information Release Form, or use Nectar, which provides API access to this utility's billing data — see docs.nectarclimate.com. Columbia Gas does not offer Green Button or a public API.

Does Columbia Gas of Pennsylvania support Green Button or EDI?

No. Columbia Gas of Pennsylvania does not implement Green Button (Download or Connect My Data) and explicitly does not support EDI. Supplier data exchange uses a proprietary flat-file File Exchange format rather than ANSI X12 or EDIFACT.

What rate schedule applies to my business?

It depends on annual throughput and whether you shop for supply. Small commercial/industrial customers (<= ~64,400 therms/year) fall under SGSS (sales) or SGDS (distribution-only); larger loads use LGSS, LDS, MLDS, or CDS. Exact per-therm distribution rates are set in the Columbia Gas PA tariff (Supplement No. 414).

How much did Columbia Gas rates change for 2026?

The PA PUC approved an annual distribution-revenue increase of about $55.6 million (roughly 6.05%) effective for service rendered on or after January 1, 2026 - far below the ~$110.5 million (12%) Columbia Gas requested. The residential customer charge rose to $23/month. C&I distribution charges also adjusted; see the tariff for per-schedule figures.
