CET helps people and businesses save energy and reduce waste. For more than 40 years, the non-profit organization has worked with partners throughout the region to help transform the way they live and work for a better community, economy, and environment.

IMPORTANT NOTE ABOUT EV CHARGERS: PMLD is always concerned with your power quality and reliability. Installing an EV Charger will put an additional load onto the distribution system and could cause a power quality issue. Please let PMLD know if you have installed an EV Charger, or are planning to install one. PMLD will inspect your transformer and upgrade it if necessary, at no cost to you.

NEW! PMLD's Commercial & Industrial Program

We now offer attractive Rebate, Incentive and Energy Audit opportunities for Commercial and Industrial customers, including a new Prescriptive HVAC Program. Learn more online, in our PDF Flyer, or by calling NEXTZERO at 413-308-1311.



PMLD parters with NEXTZERO and others, who offer a wide array of Rebates and Incentives to assist you with the costs of implementing a variety of energy efficiency measures.

PMLD is now offering a new program: Connected Homes. With Connected Homes, Princeton residential customers can better manage your smart WiFi-connected devices in your home and save money, while reducing your carbon footprint.
