Community Power Coalition of New Hampshire (CPCNH) Rate Selection 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.

Rate Recommendations by Use Case
General/medium commercial buildings (offices, retail) in a CPCNH community
Default Granite Basic supply offers stable community-power pricing without a contract; compare each period against host-utility default service.
CPCNH Granite Basic (14.0-14.9 cents/kWh for Feb-Jul 2026) is the opt-out default and is competitive with default service while supporting local programs.
- Re-benchmark CPCNH vs. default service each rate period
- Pull host-utility usage data to verify class assignment
- Opt out only if a competitive fixed price beats CPCNH net of fees
ESG-driven C&I customer needing renewable supply
Opt up to Clean 50 or Clean 100 to meet renewable/RPS goals while keeping a single consolidated utility bill.
CPCNH renewable tiers provide verifiable renewable content via one election, avoiding separate REC procurement.
- Match the tier to the exact renewable percentage you must report
- Compare the Clean 100 premium to buying RECs separately
- Document the environmental disclosure label for ESG reporting
Large demand-metered industrial/institutional load
Use CPCNH supply mapped to your host-utility large C&I class and focus optimization on interval-data-driven demand management.
For large loads, host-utility delivery demand charges often dominate; interval data from EPO/Unitil/NHEC drives the biggest savings while CPCNH provides competitive supply.
- Set up Eversource EPO or Unitil downloads for interval analysis
- Target peak-demand reduction to cut delivery demand charges
- Evaluate group net metering for on-site generation
Historical Rate Trends
CPCNH resets supply rates roughly semiannually by board action based on its cost of service. The default Granite Basic rate moved from 13.419 cents/kWh (through Jan 31, 2026) to a 14.0-14.9 cents/kWh band effective February 1, 2026, reflecting market supply costs and a new community-reserve adder.
February 1, 2026
Granite Basic default supply rate set to a 14.0-14.9 cents/kWh band (e.g., 14.663 cents/kWh in Portsmouth), up from 13.419 cents/kWh, including a community-reserve adder.
~+4% to +11% (varies by utility/class)August 1, 2025
Prior CPCNH supply-rate period (Aug 2025-Jan 2026) with Granite Basic default near 13.419 cents/kWh.
n/aOverall trend: Modestly increasing into 2026, driven by wholesale supply costs and the addition of a community-reserve adder to retire financing obligations.
Next expected change: Next scheduled supply-rate reset expected around August 2026 (CPCNH publishes Feb-Jul and Aug-Jan periods).
Cost Optimization Strategies
Because CPCNH controls only the supply portion, C&I cost optimization centers on comparing supply options, matching renewable tiers to goals, and reducing/shaping consumption using host-utility interval data.
Compare CPCNH vs. default service vs. competitive supply
For: All C&I accounts
Benchmark the CPCNH Granite Basic rate against the host utility's current default-service supply rate and any competitive C&I offers each rate period; switch or opt out if a better fixed price is available.
Right-size the renewable tier
For: C&I with sustainability targets
Elect Granite Basic for lowest cost, or opt up to Clean 50/Clean 100 only to the extent needed for ESG/RPS goals, since higher tiers carry a per-kWh premium.
Use host-utility interval data to manage load
For: Demand-metered C&I
Pull interval data (Eversource EPO, Unitil daily, NHEC AMI) to identify peak usage and shift/curtail load, lowering both supply kWh and host-utility delivery demand charges.
Leverage group net metering / on-site generation
For: C&I with on-site generation
Use CPCNH group net metering and REC aggregation to offset supply costs for members with solar or other distributed generation.

Deregulated Market Shopping
NH offers retail electric choice. In CPCNH communities, customers are enrolled in CPCNH supply by default (opt-out) but may instead take host-utility default service or sign with a competitive supplier. Delivery charges are unaffected by the supply choice.

Frequently Asked Questions
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.
