Rate Schedules & Tariff Analysis
ONG C&I bills are built from a fixed monthly Service Charge, a per-Dth Delivery Fee, and (for larger sales/transportation schedules) a Monthly MDQ demand fee for reserved pipeline capacity. The volatile commodity cost of gas is passed through separately via the Purchased Gas Adjustment (Tariff 1001), so distribution margins are stable while the gas-cost line moves with the market. Choosing between sales (200/291-S) and transportation (291-T) service is the main structural decision for large users.
Oklahoma Natural Gas (ONG) Rate Schedule List
| Schedule | Applicability |
|---|---|
| 200-SCI / 200-LCI Sales | Non-residential sales up to 5,000 Dth/yr |
| 291-S Sales | Non-residential firm sales, 5,000-30,000 Dth/yr |
| 291-T Transportation | Transportation customers, 5,000 to <30,000 Dth/yr |
Oklahoma Natural Gas (ONG) Rate Features & TOU Details

Natural Gas Transportation Service
Commercial/industrial customers with 5,000+ Dth annual usage can buy gas from an OCC-approved third-party supplier while ONG provides distribution under transportation tariffs (e.g., 291-T). The chosen supplier receives monthly 867 EDI usage data; ONG dual-bills distribution charges.

- 02Select an OCC-approved supplier from ONG's Gas Suppliers list
- 03ONG establishes a transportation account
- 04Supplier receives monthly usage via 867 EDI

Oklahoma Natural Gas (ONG) Data Access FAQ
Can we pull Oklahoma Natural Gas usage data through an API?▾
Not directly from ONG. There is no public ONG API and no Green Button. The practical programmatic path is Nectar, which (with customer authorization) normalizes ONG billing history and exposes it via REST API — see docs.nectarclimate.com. Transportation suppliers receive monthly 867 EDI usage data, but that channel is limited to OCC-approved suppliers.
How far back does Oklahoma Natural Gas billing history go online?▾
MyAccount retains 13 months of PDF statements. Older history must be requested from customer service, or accessed through Nectar, which may hold a longer collected history.
Which tariff applies to our commercial or industrial gas account?▾
ONG assigns sales-service customers by annual volume: 200-SCI for small sales (<150 Dth), 200-LCI for large sales (150 to <5,000 Dth), and 291-S for 5,000-30,000 Dth. Customers above ~5,000 Dth can instead take transportation service (e.g., 291-T) and buy gas from a third-party supplier.
Can our facility get 15-minute interval gas data?▾
Only if your meter is on ONG's limited AMR network, mostly in the Oklahoma City area. Interval data is not shown in MyAccount and must be requested from customer service; most accounts have monthly reads only.
How are ONG commercial gas charges structured?▾
ONG bills a fixed monthly Service Charge plus a per-Dth Delivery Fee, with the commodity cost of gas added separately under the Purchased Gas Adjustment (Tariff 1001). Larger sales and transportation schedules (291-S/T) add a Monthly MDQ (demand) Fee for reserved pipeline capacity. All rates are OCC-approved.
