The Vermont Public Service Board supervises the rates, quality of service, and overall financial management of Vermont's public utilities: electric, gas, telecommunications and private water companies.

The board also supervises cable television companies, reviews the environmental & economic impacts of proposals to purchase energy supply or build new energy facilities, monitors the safety of hydroelectric dams, evaluates the financial aspects of nuclear plant decommissioning and radioactive waste storage, reviews rates paid to independent power producers, and oversees the statewide Energy Efficiency Utility.
