Rate Schedules & Tariff Analysis
C&I gas rates at Boston Gas are driven mostly by the per-therm distribution charge tier (which falls as volume rises) plus the CGAC supply pass-through and the LDAC. Because supply is deregulated, the largest controllable lever for high-volume C&I customers is buying the commodity from a competitive supplier and using National Grid for delivery. The pending D.P.U. 26-50 rate case (~$342M) will raise distribution charges effective January 1, 2027.
Boston Gas Company d/b/a National Grid Rate Schedule List
| Schedule | Applicability |
|---|---|
| Rate G-41 / G-51 | Small C&I (low / high load factor) |
| Rate G-42 / G-52 | Medium C&I |
| Rate G-53 | Large C&I |

Limitations & Considerations
- ⚠National Grid does not provide automated API access to billing data through the standard My Account portal; automated third-party access requires Green Button Connect or EDI.
- ⚠Energy Profiler Online interval data is non-billing-quality and may contain gaps when meters cannot communicate.
- ⚠Specific per-therm distribution dollar figures are published only in the filed tariff provisions and change with rate cases (e.g., pending D.P.U. 26-50).
- ⚠EDI access is limited to approved ESCOs/suppliers and is not available to individual retail customers.
Boston Gas Company d/b/a National Grid Data Access FAQ
Can my business buy gas from a competitive supplier instead of National Grid?▾
Yes. Massachusetts gas supply is deregulated, so C&I customers can purchase the gas commodity from any DPU-licensed competitive supplier while National Grid continues to provide regulated delivery. If you don't choose, you receive default Cost of Gas service from National Grid at a regulated pass-through rate.
How do I get my facility's interval gas usage data?▾
Enroll your facility in National Grid's Energy Profiler Online (EPO) service, which requires an interval-capable meter (call 1-800-322-3223 to confirm). EPO provides daily, weekly, and monthly load shapes. Sub-hourly data and bill history are also available through Green Button Connect.
How can a consultant access our data automatically?▾
Have your consultant register with National Grid's Green Button Connect My Data program (operated by UtilityAPI). You authorize access via OAuth 2.0, and they retrieve bill and usage data through the API without you sharing login credentials. You can revoke access at any time.
What rate class is my business on?▾
Boston Gas assigns C&I customers to rate classes (G-41, G-42, G-51, G-52, G-53, etc.) primarily by annual therm usage, load factor, and meter capacity. Your class appears on your bill; verify it as usage changes, since high-load-factor classes can carry more favorable per-therm distribution charges.
Are gas rates changing soon?▾
Yes. National Grid filed base distribution rate case D.P.U. 26-50 on January 16, 2026 seeking roughly $342 million in additional distribution revenue. A DPU decision is expected by November 30, 2026, with new rates taking effect January 1, 2027.
Does National Grid support EDI for suppliers?▾
Yes. Approved energy service companies (ESCOs) can use ANSI X12 EDI (814 enrollment, 810 billing, 867 interval, and acknowledgment transactions) after obtaining DPU certification, submitting the supplier documentation package, and completing EDI testing with National Grid.
