The Consumer Protection Division is responsible for enforcing Maine's "monopolies and profiteering" (or antitrust) law. Maine antitrust law prohibits conspiracies in restraint of trade (e.g. price fixing), monopolization offenses, and mergers that may substantially lessen competition. We investigate potentially anticompetitive conduct within and outside the state which has or could harm Maine consumers and bring actions in state and federal court to enforce the state's antitrust law, and to bring claims on behalf of the state and consumers.

Antitrust in the Oil and Gas Industry

Maine law requires 30 days-advance notice to the Attorney General prior to acquiring retail gasoline or heating oil assets.

The Maine Atty. Gen. does not monitor gasoline or heating oil prices. When price increases do not appear to result from market-driven causes, the FTC alerts the appropriate state Attorney General

Maine's Petroleum Market Share Act requires wholesale suppliers of home heating oil and motor fuel oil to provide annual reports to the Attorney General of gallons sold to retailers and end users. See 10 M.R.S. sec. 1673. The Act also states that every 2 years the Attorney General shall make a report to the Legislature describing the concentration of retail outlets in the State, and recommending whether additional legislation is needed. Also, the Attorney General posts aggregate data collected pursuant to the Act annually. Links to the reports/data are below.
