Commercial and industrial Eversource NH bills have two distinct components: regulated delivery (NHPUC No. 10) and competitive or default generation supply. Delivery charges for GV and LG classes are dominated by per-kW demand charges, making peak-demand management the largest lever. Generation supply can be optimized by shopping competitive suppliers in NH's deregulated market.

Limitations & Considerations
- ⚠Green Button Connect My Data (automated third-party API) is still in development for New Hampshire; mature only in Eversource's Massachusetts territory.
- ⚠Energy Profiler Online interval data is limited to GV and LG rate classes (commercial/industrial); residential and small commercial cannot access EPO directly.
- ⚠Customer portal has no native CSV/XML billing export; Green Button or aggregator platforms are required for structured data.
- ⚠AMI smart meter deployment is still in progress in NH; 15-minute interval data availability depends on meter type and location.
- ⚠NH-specific EDI implementation guides are still being finalized through the EDI-EBT Working Group; MA EBT guides are referenced for X12 4010.
Public Service Company of New Hampshire (Eversource) Data Access FAQ
How can a commercial or industrial customer in NH get 15-minute interval data?▾
GV (100-1000 kW) and LG (>1000 kW) accounts use Energy Profiler Online (EPO), the primary interval-data channel. A signed EPO Service Agreement provides secure portal credentials within 2 business days. Pricing is roughly $50 one-time, $25/month, or $300/year per account. Smaller accounts rely on Green Button or aggregator platforms.
Can a consultant or broker pull our usage data on our behalf?▾
Yes. The EPO Service Agreement doubles as a Letter of Authorization, allowing brokers and consultants to request interval usage (GV/LG) and ICAP tag data. Aggregator platforms like UtilityAPI (Green Button OAuth) and Urjanet (credential-based) also retrieve bills and usage once the customer authorizes access.
How far back does Eversource NH usage and billing data go?▾
The online portal shows up to 36 months of billing history. Green Button downloads provide 13 months of usage. EPO interval data can extend 24+ months depending on meter type.
Does Eversource NH support EDI for competitive suppliers?▾
Yes. Eversource supports ANSI X12 v4010 EDI for registered CEPS and aggregators, including 814 (enrollment/change/drop), 810 (usage/invoice), 867 (historical usage), 820 (payment), and 997 (acknowledgement), with 2- and 3-part TOU and net metering support.
Is electricity supply deregulated for businesses in New Hampshire?▾
Yes. NH has retail electric choice. Eversource provides regulated delivery plus a default energy service (about $0.11303/kWh for Feb-Jul 2026), and C&I customers may instead buy generation from a competitive supplier. Compare offers at Energy Switch NH.
