Energy

This bill ends Maine's net energy billing program, which allowed residential and commercial solar customers to receive bill credits for excess electricity they sent back to the grid. It repeals all existing rules governing this program (including sections 3209-A, 3209-B, and 3209-C) and explicitly prohibits the Public Utilities Commission from requiring utilities to offer net energy billing in the future. The change directly affects current and future solar customers who previously relied on this billing method for compensation. It shifts Maine's policy away from compensating solar generators for exported energy toward a different framework for distributed generation.

LD 1138 requires Maine's Department of Transportation and the Maine Turnpike Authority to conduct greenhouse gas emissions and traffic impact assessments before approving new road expansions or capacity increases (like adding lanes or improving roadways). Starting July 1, 2026, these assessments must project 20-year emissions, net changes in vehicle miles traveled, and account for "induced demand" (increased driving from new road capacity). Projects found inconsistent with Maine's climate targets must be redesigned, include mitigation measures, or be canceled. The bill directly affects transportation planning decisions for state road projects and aims to align infrastructure development with the state’s climate action goals.

LD 1321 reformulates Maine's net energy billing program for solar and renewable energy systems. It limits new residential and small commercial systems to 20 kilowatts after November 2025 (with limited exemptions), caps shared ownership to 10 customers per project, and restricts individuals to owning no more than 5 systems. The bill sets a hard end date of December 31, 2045, or 20 years from a system's agreement date, whichever comes first. It also requires that renewable energy credits generated must be sold within Maine and adjusts compensation rates based on historical utility rates with annual 2.25% increases. This directly affects residential and small commercial customers with solar installations participating in net energy billing.

LD 741 requires Maine's Technical Building Codes and Standards Board to update the state's building code to include solar energy standards from Appendix CB of the 2021 International Energy Conservation Code for all new commercial buildings. This affects developers and builders constructing new commercial properties after the effective date. The bill exempts buildings that already secured all permits before July 1, 2026, and any projects receiving funding from the Maine State Housing Authority. The key change ensures new commercial construction incorporates solar-ready infrastructure from the start, without mandating solar panel installation.

LD 830 requires solar energy developments in Maine to be concealed from view using a barrier like trees, bushes, or fencing that hides the panels from adjacent properties. The Department of Environmental Protection must verify this concealment before approving any new solar project. This bill directly affects solar developers, who must design projects with such barriers, and the Department, which gains authority to enforce this requirement during approvals.
