EV Charger Program

Monitor and Control Charging of Your EV from the Palm of Your Hand!

Sterling Municipal Light Department (SMLD) has partnered with its energy efficiency program manager, Massachusetts Municipal Wholesale Electric Company, (MMWEC), to provide a free or discounted Wi-Fi-equipped Level 2 residential electric vehicle charger to customers signing on to the NextZero Scheduled Charging Program.

What is a Scheduled Charging Program?

Scheduled charging is a set schedule to determine when a charger can be used at full power. Through the Wi-Fi connection enabled in the charger, SMLD will power off the EV charger during periods of peak energy usage for the rest of our distribution system. Learn more by downloading SMLD’s charging agreement or check to see if your EV model qualifies. Visit the Department of Energy Resource’s Alternative Fuels Data Center to compare different EV models.

How it Works

Between the hours of 5:00 p.m. and 9:00 p.m. on non-holiday weekdays, your EV charger will not charge. Outside of this time period, the charger will automatically unlock to allow you full Level 2 fast-charging functionality.

Emergency Scheduling

Sometimes major events happen on the electrical system outside of our control. To respond to these events, emergency scheduling allows SMLD to temporarily access your charger via Wi-Fi connection to lower your charging rate until the event passes. This limits strain to our system and allows us to continue to deliver low-cost, reliable electricity.

Charger Incentive

SMLD customers are eligible for a free charger for electric vehicles (EVs) and a $200 or $300 rebate for plug-in hybrids (PHEVs) in exchange for enrolling the charger into the Scheduled Charging Program. Refer to the table below for more information.
