Five electric utilities in one county
Eversource lists most towns here. Four town-owned utilities cover the rest or part of it, according to the Connecticut Municipal Electric Energy Cooperative:
- Norwich Public Utilities serves about 21,000 customers in the City of Norwich.
- Groton Utilities serves about 14,000 customers in the City of Groton and portions of the Town of Groton.
- Bozrah Light & Power serves about 2,800 customers in Bozrah and portions of Montville and Lebanon.
- The Jewett City Department of Public Utilities serves about 2,700 customers in the Borough of Jewett City, in Griswold.
Eversource's list also names Norwich, Groton, Montville, Lebanon and Griswold, so in those towns your bill decides. It does not name Bozrah.
What changes in town-owned territory
SunPol offers a cash purchase or a loan only in town-owned territory. The Solar PPA, Propel and the Prepaid Solar Program are not offered there.
- Norwich Public Utilities uses buy-all/sell-all metering: all of a system's output is exported at a set rate and all electricity you use is bought at the standard residential rate. Its credit rate effective November 1, 2026 is $0.06321/kWh plus the variable purchased-power adjustment. The contractor supplies a utility-grade meter socket shown on the single-line diagram, and a production meter is required.
- Groton Utilities (which also runs the Bozrah Light & Power web pages) lists a SolarPlus residential solar-and-battery rebate pilot (solar installed in tandem with a battery) for systems up to 12 kW AC at 1–2 family homes; confirm current terms with Groton Utilities. The system must be owned by the customer, and third-party ownership is not permitted in its territory. Interconnection must be approved and the rebate reserved before installation.
- Bozrah Light & Power and the Jewett City DPU: ask the utility for its current interconnection rules before design.

Ways to go solar in New London County
- Solar PPA: pay for the power from 16¢/kWh† for qualified customers, no upfront system cost, yearly increase 0% to 2.99%†. You will still get a utility bill.
- Direct ownership: cash purchase or loan, same price; you own the system, with SunPol's 10-year workmanship warranty.
- Propel: always loan-financed; SolSource owns the system first and a prefunded Early Buyout is applied after Contract Year 5 unless you opt out§. Project and lender approval required.
- Batteries: Tesla Powerwall 3 with a Solar PPA, direct ownership or Prepaid; FranklinWH aPower 2 with direct ownership; Enphase IQ Battery 10C with Propel. A home battery on its own: a 10- or 12-year Tesla Powerwall 3 lease through our financing partner, or a cash or loan purchase of a Tesla Powerwall 3 or FranklinWH aPower 2. Backup for your essential circuits; run time depends on your usage and battery size. You will still get a utility bill.
- Prepaid Solar Program: 30% lower program price than buying the same system*, paid upfront, no monthly payments to SunPol*, 25 years of system coverage*, for systems in service by Dec 31, 2027*. You will still get a utility bill.
Homes served by a municipal electric utility can choose a cash purchase or a solar loan; the Solar PPA, Propel and the Prepaid Solar Program aren't offered there.
Prepaid Solar Program: how it compares with buying
- The Prepaid Solar Program is one price paid upfront for 25 years, with no monthly program payments: exactly 30% less than buying the same system, for systems in service by December 31, 2027.
- Estimated breakeven is about 8–10 years,
- with an estimated $30,000–$60,000 in savings over 25 years.
Savings are not guaranteed. You will still get a utility bill.
How it works
- Share your bill. About 2 minutes.
- Get your custom design. Payment options with real numbers, on a 30-minute call.
- We handle the rest. Permits, installation and utility paperwork, with Eversource or one of four town-owned utilities depending on your address.
