Current Rate Schedules
National Grid NY gas delivery (distribution) charges are set by the NY PSC and structured as a fixed minimum charge for the first few therms plus declining per-therm blocks. The commercial classes are SC-2 (Non-Residential, split into Non-Heating SC-2-1 and Heating SC-2-2), SC-3 (Multi-Family), SC-4A (High Load Factor), and SC-21 (large firm transportation, tiered by MW). Figures below are KEDNY delivery charges verified effective April 1, 2026 (exclusive of GRT); KEDLI rates differ. Gas supply (commodity) is separate and varies by chosen ESCO or National Grid default.

Rate Recommendations by Use Case
General commercial building (heating)
SC-2-2 Heating service; shop the commodity and target heating efficiency.
Heating service carries the highest per-therm delivery; commodity choice and efficiency on heating peaks drive savings.
- Compare ESCO fixed-price offers against National Grid default supply
- Use Green Button data to benchmark heating load
- Confirm correct heating vs non-heating class placement
Multi-family property
SC-3 Multi-Family service with whole-building benchmarking.
SC-3 declining-block delivery suits multiple-dwelling load; benchmarking supports NYC LL97 / energy reporting.
- Pull 24 months of usage via My Account / Green Button
- Authorize a benchmarking partner via UtilityAPI
- Evaluate ESCO supply for the building's aggregate load
Large industrial / high load factor
Evaluate SC-4A High Load Factor or SC-21 Transportation.
Large steady loads get materially lower per-therm delivery on SC-4A/SC-21; transportation enables direct commodity procurement.
- Model load factor to qualify for SC-4A
- If on SC-21, manage MPDQ and nominations via GTIS
- Engage an ESCO or marketer for transportation supply
Energy consultant / aggregator
Use Green Button Connect via UtilityAPI for automated data.
Green Button Connect provides standardized monthly gas data without ESCO/EDI overhead for non-ESCO consultants.
- Register at utilityapi.com and pass National Grid review
- Request data for utility NGNY (gas, monthly)
- Combine with NY System Data Portal for siting/grid context
Historical Rate Trends

Next expected change: Annual delivery-charge update; next statement typically effective April 1.
Cost Optimization Strategies
The largest C&I gas-cost levers on National Grid NY are choosing a competitive ESCO for the commodity, fitting the correct delivery service class, and managing seasonal/load-factor profile.
Shop the gas commodity (ESCO)
For: All commercial and industrial gas accounts
Buy the supply portion from a competitive ESCO via the NY PSC Power to Choose marketplace. Fixed-price contracts can hedge winter price spikes; delivery charges are unaffected.
Right-size the service class
For: Large / high-load-factor gas users
Confirm placement in the lowest-cost applicable class — e.g., high-load-factor SC-4A or transportation SC-21 for large steady loads vs general SC-2, which carries higher per-therm delivery.
Capacity / nomination management (transportation)
For: SC-21 large transportation customers
Transportation customers on SC-21 manage MPDQ demand and monthly nominations via GTIS; accurate nominations avoid imbalance and demand penalties.
Interval analytics for load shaping
For: Commercial customers with interval meters
Use Energy Profiler Online or Green Button data to identify usage patterns and target efficiency on heating-driven peaks (SC-2-2 carries the highest per-therm delivery).
To implement these strategies, you need your 15-minute interval data. Learn how to download KeySpan Energy d/b/a National Grid (New York Gas) interval data →

Frequently Asked Questions
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).
