Typical savings

Program overview
Maine's Net Energy Billing program (governed by P.L. 2019 c. 478, P.L. 2021 c. 390, and PUC Chapter 313) was the engine of the state's community solar growth. LD 1777 and LD 1792 - passed in 2025 - close NEB to new front-of-meter projects effective December 31, 2025, reform the tariff-based credit, and add stronger consumer protections. Existing 5 MW projects continue to operate under their original tariff terms; a successor program is in active rulemaking.
The laws & rules
Established the two NEB sub-programs (kWh credit and tariff-rate) that drove ~750 MW of community solar development in Maine.
Closes NEB to new front-of-meter applicants on 12/31/2025, reduces the tariff-rate credit going forward, and tightens subscriber consumer protections.
Companion bill addressing rate impacts and successor-program design parameters.
Existing front-of-meter projects capped at 5 MW. Successor program structure under PUC rulemaking.

What Cannon does in Maine
We're tracking PUC rulemaking and positioning sponsor and landowner pipelines for day-one application under the replacement program.
Construction of any remaining NEB-eligible projects through 2025 close, plus build-ready successor pipeline once rules are finalized.
Maine's installed NEB community solar fleet needs 25-year O&M. CANOS takes over orphaned, distressed, or sponsor-owned sites in 30–60 days - with a real Maine response footprint.
Migration support for subscribers as projects move between owners, and bill-credit reconciliation under the revised LD 1777 tariff structure.
Why we win Maine
