Municipalities may own, maintain and operate a municipal light plant (MLP) in order to provide electric and/or gas services to their citizens.
Forty-one communities have established MLPs that serve all or part of 50 municipalities for electric service.
Generally, MLPs are run by municipal light boards or commissions in a municipality, or by the mayor/board of selectmen.
The DPU’s role in regulating MLPs is limited since MLP's rates are set by municipal officials. The MLP provides both distribution and supply service to its customers.
