Community Power Coalition of New Hampshire (CPCNH) Data Access Guide
CPCNH is a nonprofit Community Choice Aggregator that procures electricity supply for 68+ New Hampshire municipalities and counties on an opt-out basis. It sets supply (generation) rates only; metering, billing, and usage data remain with the host distribution utilities (Eversource, Liberty, Unitil, NHEC), so C&I data access runs through those utilities.

Billing Data Access
CPCNH does not issue bills or maintain a billing system. Customers receive a single bill from their host distribution utility (Eversource, Liberty, Unitil, or NHEC) that includes both utility delivery charges and CPCNH supply charges. Billing and usage history must be accessed through the host utility's portal; the CPCNH portal handles only enrollment and supply-rate/renewable-tier selection.

Rate Schedules & Tariff Analysis
CPCNH competes against host-utility default service and competitive suppliers on the supply portion only. Its February 2026 Granite Basic band of 14.0-14.9 cents/kWh reflects cost of service plus a community-reserve adder. C&I buyers should compare the CPCNH rate (and any opt-up tier premium) against the host utility's current default-service supply rate and any third-party offers, while delivery charges remain constant regardless of supplier.
Community Power Coalition of New Hampshire (CPCNH) Rate Schedule List
| Schedule | Applicability |
|---|---|
| Granite Basic - General & Outdoor Lighting | Small/general commercial supply |
| Granite Basic - Medium Commercial | Medium commercial supply |

Limitations & Considerations
- ⚠CPCNH provides supply (generation) rates only; it does not own meters, issue bills, or hold usage data.
- ⚠All billing and interval data access flows through the host utility (Eversource, Liberty, Unitil, NHEC), each with different capabilities.
- ⚠Green Button Connect My Data is not yet live in NH (Unitil pilot targeted 2026-2027).
- ⚠Liberty interval data is limited until its smart-meter rollout completes (2026-2027).
- ⚠Brokers/consultants cannot exchange EDI directly with utilities; they must work through a registered supplier.
Community Power Coalition of New Hampshire (CPCNH) Data Access FAQ
How do C&I customers get interval data for a CPCNH account?▾
Through the host distribution utility, not CPCNH. Eversource provides 15-30 minute interval data via Energy Profiler Online (EPO) for eligible C&I accounts, accessible by brokers with a signed LOA. Unitil offers daily usage (90 days) plus monthly billed usage (24 months) with spreadsheet export. NHEC provides hourly AMI data via SmartHub. Liberty interval access expands as its smart-meter rollout completes.
Does CPCNH set delivery rates or just supply?▾
CPCNH sets only the supply (generation) portion of the bill. The host utility sets and bills the regulated delivery charges. A CPCNH customer sees both on one consolidated utility bill.
What renewable supply options exist for commercial accounts?▾
CPCNH offers tiered products: Granite Basic (default), Granite Plus, Clean 50, and Clean 100. Higher tiers carry more renewable content at a different per-kWh price, letting C&I customers align electricity supply with sustainability targets.
Can a third party access CPCNH C&I data programmatically?▾
Not directly from CPCNH, which has no public API. Nectar provides API access to billing and usage data for the NH host utilities — see docs.nectarclimate.com — alongside host-utility programs such as Eversource EPO. When Unitil's Green Button Connect My Data pilot goes live, OAuth-based ESPI interval access will be available for Unitil customers.
How is a CPCNH C&I customer billed and how often do supply rates change?▾
The host utility issues a single monthly bill combining delivery and CPCNH supply charges. CPCNH supply rates are reset by board action (e.g., the rate effective February 1, 2026), typically on a semiannual basis tied to its cost of service.
