How Unitil Corporation and Retail Suppliers Work Together
Unitil serves northern MA and southern NH.
Unitil handles distribution. CES competition applies. The supply portion of your bill — typically the largest single line item for commercial accounts — is where retail competition applies. That's the piece a broker targets.
Unitil rates are regulated by MA DPU and NH PUC depending on the service territory.
What "Switching Suppliers" Means for Unitil Corporation Customers
Standard ISO-NE process for CES switching applies.
Smaller CES market than Eversource/National Grid territories.
The process: you authorize a supplier to serve your account, they notify Unitil Corporation, and the change takes effect at your next billing cycle. No technician visit. No service interruption. Same reliability, different supply rate.

Understanding Your Unitil Corporation Commercial Bill
A typical commercial Unitil Corporation bill has several distinct charges:
- Supply charge: Cost of electricity generation. This is negotiable — it's what retail suppliers compete on.
- Distribution/delivery charge: Unitil Corporation's fee for owning and maintaining the wires. Regulated, fixed.
- Transmission charge: High-voltage grid cost, managed by ISO-NE. Regulated, fixed.
- Demand charge: Based on your peak 15-minute interval each month. Can represent 30–50% of your total bill.
- Capacity charges: ISO-NE capacity market costs. Pass-through, not negotiable with suppliers.
A broker focuses on the supply charge — the one component where you have leverage. We make sure you understand all other charges so there are no surprises.
Frequently Asked Questions
Does switching suppliers affect my Unitil Corporation service?
No. Unitil Corporation handles physical delivery of electricity regardless of which supplier you choose. Standard ISO-NE process for CES switching applies. Your Unitil Corporation account number stays the same; you'll simply see a different supplier name on the supply portion of your bill.
Why is my Unitil Corporation bill so high?
Commercial Unitil Corporation bills have several components: supply charges (electricity generation), delivery charges (wires and poles), transmission, capacity charges, and taxes. Only the supply charge is negotiable through a retail supplier. Unitil handles distribution. CES competition applies.
What is Unitil Corporation's default service rate?
Unitil Corporation's default service (or 'provider of last resort' service) is the rate applied to accounts that haven't chosen a retail supplier. Unitil rates are regulated by MA DPU and NH PUC depending on the service territory. Competitive suppliers often offer better rates than default service for commercial accounts.
How do I get competing quotes for my Unitil Corporation account?
We pull your 12-month usage history from Unitil Corporation (with your authorization), build your load profile, and submit to 30+ active retail suppliers in the Unitil Corporation territory. You receive competing offers within 24–48 hours at no cost.
What's the difference between Unitil Corporation and a retail energy supplier?
Unitil Corporation owns the wires that deliver electricity to your building. A retail energy supplier (REP) generates or purchases the electricity itself. You pay Unitil Corporation for delivery and your chosen supplier for supply — two separate charges on one or two bills depending on the market structure.
