PROPOSED RATE AMENDMENTS

REGULATORY CHARGE: FIEC proposes a fixed monthly Regulatory Assessment per meter to recover the cost of the annual assessments charged by the Maine Public Utilities Commission (Commission), the Maine Office of the Public Advocate, Efficiency Maine Trust, and amounts due to the Maine State Housing Authority for expired net energy billing credits (per M.R.S. 35-A §3209). The rate will be updated each year to reflect changes by governmental entities. Every customer with an active meter will pay this charge each month, regardless of kWh use.

The estimated 2026–2027 charge would be:

$74.66 per meter annually

$6.22 per month

LOW-INCOME ASSESSMENT CHARGE: FIEC proposes replacing the current kWh-based LIAP Assessment with a fixed monthly charge per meter. The rate will be updated each year to reflect changes by governmental entities. Every customer with an active meter will pay this charge each month, regardless of kWh use.

The estimated 2026–2027 charge would be:

$33.39 per meter annually

$2.78 per month

DECREASED DELIVERY RATE: To avoid overcollection of regulatory costs, FIEC proposes decreasing T&D rates by $30,263, which is the amount currently included in the T&D rates for regulatory expenses, as follows:

Rate Class T&D Rate/kW Proposed T&D Rate/kW % Change

Residential $0.13708/kWh $0.13435/kWh -2.03%

Residential Peak Period $0.11028/kWh $0.10345/kWh -6.60%

Commercial $0.09752/kWh $0.09299/kWh -4.87%

Large Commercial $0.09094/kWh $0.09071/kWh -0.25%

Small Power $0.12311/kWh $0.12280/kWh -0.25%
