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.

Check into all the saving opportunities now!
