The Princeton Municipal Light Department (“PMLD”) has been providing electrical service to the businesses and residents of Princeton for over 100 years.  The mission of the Princeton Municipal Light Department is to provide a safe, reliable, and economical source of electric power for our customers, to acknowledge and implement the need for renewable energy from within the diversity of available energy sources, and to enhance the benefits of municipal utility ownership for our customers.  The PMLD has its own elected Board of Commissioners, General Manager, and staff that operate autonomously from the Town of Princeton Selectmen, Town Administrator, and other boards and committees.
