Current Rate Schedules
Eversource NH bills electric delivery under NHPUC No. 10 (Electricity Delivery). Commercial and industrial customers fall into demand-metered classes - notably Rate GV (100-1000 kW) and Rate LG (>1000 kW) - which combine a monthly customer charge, a per-kW demand charge, and per-kWh delivery energy charges, plus state riders (Stranded Cost, System Benefits, Storm, etc.). Generation supply is separate: Eversource Default Energy Service was about $0.11303/kWh for Feb-Jul 2026, or customers may shop competitive suppliers. Exact C&I delivery $/kW and $/kWh figures vary by rate sheet and effective date; consult the NHPUC No. 10 tariff book and the NH Summary of Electric Rates for current values.

Rate Recommendations by Use Case
Mid-size commercial building (100-1000 kW)
Office, retail center, or light-manufacturing site in Eversource NH's GV demand class.
GV accounts are demand-metered and EPO-eligible, so per-kW demand charges dominate delivery cost. Interval data unlocks targeted peak management.
- Subscribe to Energy Profiler Online for interval data
- Shave coincident peaks to reduce billed demand
- Shop competitive supply against Default Energy Service
Large industrial facility (>1000 kW)
Manufacturing or large institutional load above 1,000 kW on Rate LG.
LG is the largest demand class; demand and supply both materially affect cost, and custom competitive supply contracts are common.
- Use EPO interval data for demand-response and load shifting
- Negotiate a custom competitive supply contract
- Monitor power factor and statewide riders
Small business / storefront
Small commercial account below demand-metering thresholds (Rate B).
Energy-only delivery keeps billing simple; the main lever is comparing competitive supply against default energy service.

Cost Optimization Strategies
For Eversource NH C&I customers, the biggest savings come from managing peak demand (which drives per-kW delivery charges) and shopping competitive generation supply in NH's deregulated market.
Peak demand management
For: Rate GV, Rate LG
Stagger equipment startups and shift discretionary loads off coincident peaks to lower the billed per-kW demand charge on GV/LG accounts. Use EPO interval data to find peaks.
Shop competitive generation supply
For: All C&I classes
Compare competitive electric power suppliers against Eversource Default Energy Service (~$0.11303/kWh Feb-Jul 2026). Larger C&I loads often secure custom fixed-price contracts.

Frequently Asked Questions
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.
