Rate Schedules & Tariff Analysis
Columbia Gas of Virginia C&I rates combine a fixed customer charge, a SAVE Rider, tiered declining-block volumetric charges, and — for Large General Service — a monthly demand charge ($14.53/Dth effective 5/29/2026). The volumetric rate bundles base gas (commodity, replaceable via CHOICE/TS), base non-gas (delivery), and PGA/ACA adjustments. Larger volumes earn lower marginal rates, so right-sizing the rate schedule and managing demand and balancing are the key levers.

Columbia Gas of Virginia Data Access FAQ
How can a C&I customer or consultant access our gas usage history?▾
Two paths: (1) the customer authorizes sharing via the Release of Information form and the third party requests data from Columbia Gas; or (2) for Transportation Service C&I accounts, an approved supplier retrieves usage history through the Historical Data Portal (hdp.columbiasuppliers.com, company 38) using Aviator credentials. There is no public API or Green Button feed.
Does Columbia Gas of Virginia support EDI or a public API?▾
No. Columbia Gas does not use traditional ANSI X12 EDI and does not publish a public REST API or Green Button endpoint. Suppliers exchange data through NiSource's proprietary flat-file File Exchange (encrypted FTP), the Aviator nomination system, and the Historical Data Portal.
Which rate schedule applies to a commercial or industrial account?▾
Small commercial accounts fall under Small General Service (SGS-1/2/3) by annual volume (0-208.9, 209.0-626.6, and >626.6 Dth). Larger accounts use Large General Service (LGS-1 for moderate volumes, LGS-2 for very large) with a monthly demand charge plus tiered volumetric rates, and may elect Transportation Service (TS-1/TS-2) or Standby Service.
What does an LGS customer pay as of mid-2026?▾
Per the tariff effective 5/29/2026 (Case PUR-2024-00030), LGS-1 has a monthly demand charge of $14.53/Dth and a customer charge of $719.39 plus a $312.82 SAVE Rider, with firm billing rates of ~$5.50/Dth on the first 1,000 Dth declining to ~$4.02/Dth over 5,000 Dth. LGS-2 has a $3,618.47 customer charge, $1,683.58 SAVE Rider, and firm rates of ~$4.13/Dth declining to ~$3.80/Dth at higher volumes.
Can a C&I customer buy its own gas?▾
Yes. Through Transportation Service (TS-1/TS-2), a C&I customer procures gas from a supplier who nominates delivery via Aviator. Columbia Gas charges the same demand and customer charges as the firm LGS schedule, plus Banking and Balancing Service charges for imbalance tolerance.
Is interval (sub-monthly) gas data available?▾
Not as a public self-service feed. Most accounts are billed on monthly meter reads; the myAccount 'My Usage' view is monthly. C&I usage history is available to approved suppliers through the Historical Data Portal. For sub-monthly needs, contact Business Support.
