The Public Service Commission regulates telecommunications, electric, gas, water and sewer utilities. The agency is charged with assuring that rates and charges for services are just and reasonable, that the service rendered is reasonably adequate, and that any facilities constructed or acquired are required for the convenience and necessity of the public. Additionally, the agency exercises safety jurisdiction over gas pipelines and has area jurisdiction over all public utilities. In carrying out its responsibilities, the commission answers complaints, makes investigations and conducts both formal and informal hearings.
