Why Merrimac is not in the retail-choice market

Massachusetts deregulated retail electricity in 1998, but only in investor-owned utility areas. The state's 41 Municipal Light Plants (MLPs) were specifically excluded.

Eversource / National Grid territory

  • ·Shop a supplier for the supply line.
  • ·Basic Service auction price every 6 months.
  • ·Two parts on the bill: supply + delivery.

Merrimac (MLP)

  • ·Supplier choice is not available.
  • ·Rate set by local commission, usually changed once a year.
  • ·One bill, one phone number, one website.

Frequently asked questions

Can I pick a competitive supplier in Merrimac?
No. Merrimac is a Municipal Light Plant town, which Massachusetts retail choice excludes. MMLD supplies all the power its customers use.
Is my rate set by the MA DPU?
No. MMLD rates are set by the Merrimac Light Commission, which answers to the town's residents, not the state. The DPU has no authority to approve or reject the rates.
Who do I call for a downed power line?
Merrimac Municipal Light Department at (978) 346-8311, day or night. If lives are at risk, call 911 first.
