Energy Deregulation in MaineHistory of Energy Deregulation in Maine

Technically speaking, the energy industry in Maine wasn’t deregulated but rather restructured. Some of the results of its restructuring are the same as those enjoyed by deregulation in other states: lower prices for consumers and more options for “green energy” and renewables for suppliers.

Historically, the utility companies in Maine were responsible for generating and distributing power – everything from creating energy to ensuring that the power lines into homes were in good repair. Prior to 2000, most of Maine’s power came from fossil fuels, and consumer prices were higher than in many other states.

But in 2000, Maine’s state legislature implemented the Restructuring Act, and it required utilities to sell their generation assets and allowed independent distributors to open shop in the state. This now gives the residents an option for who will supply their power. The lowered energy price is only one of Maine’s many benefits from The Restructuring Act.

Soon after, the state government and provided companies built renewable power sources. These include wind turbines that can now be found everywhere in the state. Aside from this, Maine is also utilizing tidal power as another renewable energy source.

Thanks to the changes brought about by The Restructuring Act, Maine is now known as one of the biggest storehouses of renewable energy in New England. This makes living in Maine more bearable, even in the long cold winters.

Quick Energy Facts about Maine

  • Non-hydroelectric energy use. Maine has one of the highest percentages of renewable energy use in the country that isn’t related to hydroelectric power.
  • Regional Greenhouse Gas Initiative (RGGI) member. Along with ten other Northeast states, Maine is a part of the RGGI. The Initiative aims to limit greenhouse gas emissions by capping carbon dioxide emissions from the electrical generation sector.
  • Renewable Energy. The state requires the utilities in Maine to sell up to 30 percent of their energy from renewable resources
  • Gasoline is not mixed with renewable fuels. Unlike other states with deregulated energy provisions, Maine does not require its gasoline supply to be mixed with ethanol or other renewable energy.
  • No appliance efficiency standard. Other states impose an appliance efficiency standard so that appliances like freezers that are usually found in business establishments are efficient in their energy use. Maine does not have this standard, so businesses and homes can continue to use their appliances as they see fit.
  • No capping of greenhouse gas emissions. Maine does not cap the greenhouse gas emissions of the businesses in the state. But since they are members of the RGGI, they do cap the greenhouse emissions of power plants in the state.
