Energy (Solar)

LD 450 repeals Maine's net energy billing laws, prohibiting the Public Utilities Commission from requiring utilities to offer bill credits for excess solar energy sent back to the grid. It directly affects residential and commercial solar customers who currently participate in net energy billing programs and the utilities serving them. The bill removes specific statutory provisions (35-A MRSA §§3209-A through 3209-E) and adds a new section (§3209-F) explicitly banning the requirement for net energy billing. Additionally, it amends property tax exemptions for solar equipment to align with the repeal, requiring that solar-generated energy must be used on-site or connected to a net energy billing customer.

This bill eliminates Maine's net energy billing program, which allowed residential and business customers with solar installations to receive bill credits for excess electricity they sent back to the grid. It directly affects solar customers who currently participate in this program by prohibiting utilities from offering net energy billing under any circumstances. The bill repeals all related provisions in Maine law (including sections governing billing practices and tax exemptions) and explicitly states the Public Utilities Commission cannot require utilities to implement such billing. This changes how solar customers are compensated for surplus energy, shifting away from bill credits toward alternative compensation methods.

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.

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.

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 359 prohibits certain customers from participating in net energy billing (a system where solar/wind energy credits offset electricity bills) unless they have a direct financial stake in the renewable energy system. It requires customers to own, lease, or have a power purchase agreement for the system, effectively ending shared solar programs where multiple customers pool resources without direct ownership. The bill limits shared arrangements to 10 meters for investor-owned utilities and sets size limits (under 5 MW for most systems). It directly affects residential and commercial customers in "shared solar" programs who previously could join without owning the equipment. Existing projects approved before June 2021 are exempt from these new requirements.
