Pricing FAQs

Asset Publisher

There are five components that make up a delivery price. The PUC separately sets the five pieces that make up our delivery prices.

  1. The distribution piece covers the costs of local power lines, meter readers, and bucket trucks. For most customers, this makes up the majority of their delivery price.
  2. The transmission piece covers the costs of large power lines and substations and is regulated by the Federal Energy Regulatory Commission.
  3. The stranded cost (Public Policy) piece covers costs associated with purchase power agreements to encourage renewable energy, state-mandated low-income assistance programs and energy efficiency programs.
  4. The conservation assessment piece funds energy efficiency initiatives.
  5. The Electricity Lifeline Program (ELP) provides assistance to qualifying residential customers.

The prices, practices, and level of profitability are regulated primarily by the Maine Public Utilities Commission (PUC). The PUC was created by Maine law and began work in 1914. Its three commissioners were nominated by the Governor and confirmed by the Maine Senate.

The Commissioners are assisted by legal, technical, financial and consumer-assistance staff. PUC proceedings use court-like standards of evidence, procedure and decisions that allow opportunities for interested citizens or groups to participate as formal interveners in the process.
