Rate Schedules & Tariff Analysis
National Grid NY gas bills separate PSC-regulated delivery charges (declining-block per-therm plus a fixed minimum) from the gas supply commodity, which can be bought from a competitive ESCO. Delivery economics favor larger declining-block volumes and the right service-class fit; the biggest C&I lever is supplier choice on the commodity portion and selecting the correct rate class (e.g., SC-4A high load factor or SC-21 transportation for large steady loads). Heating service (SC-2-2) carries materially higher per-therm delivery than non-heating (SC-2-1).
KeySpan Energy d/b/a National Grid (New York Gas) Rate Schedule List
| Schedule | Applicability |
|---|---|
| SC-2-1 Non-Residential Non-Heating | General commercial, non-heating |
| SC-2-2 Non-Residential Heating | General commercial, heating |
| SC-3 Multi-Family | Multi-family dwellings |
| SC-4A / SC-21 Large | High load factor and large transportation |

- ⚠Green Button Connect is in beta but operational; functionality may expand.
- ⚠Energy Profiler Online requires a $600/year subscription and an interval meter.

KeySpan Energy d/b/a National Grid (New York Gas) Data Access FAQ
Can a commercial gas customer choose its own supplier on National Grid NY?▾
Yes. New York has a deregulated retail gas market. National Grid NY (KEDNY/KEDLI) remains the regulated delivery company, but commercial customers can buy the gas commodity from a competitive ESCO or take default supply from National Grid. Delivery (distribution) charges are the same regardless of supplier.
What interval data is available for commercial gas accounts?▾
Gas usage is monthly (billing-quality), with daily granularity where AMI is deployed; there is no sub-daily interval for gas. Commercial customers with interval meters can subscribe to Energy Profiler Online ($600/year) for detailed load profiles.
How does a data aggregator access National Grid NY gas data automatically?▾
Through Green Button Connect My Data on the UtilityAPI platform (certified to Green Button v3.3). Register at utilityapi.com, pass National Grid review, and request data for utility NGNY via REST API once the customer authorizes.
Which gas service classes apply to commercial and multifamily customers?▾
SC-2 (Non-Residential, split into Non-Heating SC-2-1 and Heating SC-2-2) covers general commercial; SC-3 covers Multi-Family; SC-4A (High Load Factor) and SC-21 (large transportation) serve large/industrial loads.
Is EDI access available to non-ESCO consultants?▾
Generally no. EDI is for ESCOs in the retail-access program. Non-ESCO aggregators should use Green Button Connect via UtilityAPI; large aggregators may negotiate limited EDI access with National Grid Business Customer Services (1-800-752-6633).
