The first improvement in the new HMLP IS GOING GREEN program is in the Home Energy Assessment area. HMLP and ENE will now perform an infra-red inspection of the customer’s home as a part of the assessment. This inspection will help determine energy-saving interventions, such as insulation, caulking, and window and door re-glazing or replacement.

Save money. Save Time. Save carbon. 

Now is the time to switch from gasoline to electricity. Plug-in electric cars are fast, fun, affordable, and efficient. Compared to gasoline vehicles, electric vehicles (EVs) are less costly to operate and maintenance is cheaper and simpler. 

Hingham Drives Electric is a local initiative designed to raise awareness about the benefits of replacing gasoline-powered vehicles with EVs. Residents in HMLP’s territory are encouraged to test drive and experience the speed and power of EVs first hand. The Hingham Drives Electric website helps you access available rebates (link to applications are also below), take advantage of EV deals, and stay informed on rapidly growing EV market.

Be part of this important program. Schedule a test drive to see which car is the best fit for you! Call 1-833-44-EV-ENE (1-888-443-8363) or visit the Hingham Drives Electric website to learn more. View current offers or schedule a no-obligation test drive today!

CFL bulbs are available at HMLP’s office on 31 Bare Cove Park Drive, Hingham, MA.

HMLP has had several energy efficient lighting programs with Light-Emitting Diode (LED) bulbs, including subsidizing discounts at local stores, distributing free bulbs at its office, giving bulbs to several groups at the Senior Center, sharing bulbs with Hingham students at various educational outreach programs, and making bulbs available to participants during Hingham Family Fun Day. HMLP will continue to find opportunities to encourage its customers to use LEDs. HMLP can increase LED usage by introducing the benefits of LEDs through continuing promotions (giveaways) and working with its customers when they purchase bulbs.

HMLP will offer a rebate in the form of a credit on the bills of customers who install and own a photovoltaic system at their home in Hingham. The amount of the rebate will vary according to the capacity of the photovoltaic system. There is a cap of $5,000 per account. The HMLP will rebate $1,000/kW x the rated output of the system or $5,000, whichever is less. For example, an HMLP customer who installs a photovoltaic system that has a rated output of 2.5 kW will receive a rebate credit on their bill of $2,500. If that same customer installed a system with a rated output of 10 kW, then they would receive a rebate credit of $5,000.

Commercial properties can now receive Energy Assessments that cover lighting and HVAC equipment. To schedule an assessment, please call Energy New England (ENE) at 888-772-4242 or email

HMLP has contracted with Energy New England to provide energy management studies and to develop a plan of action for each energy conservation measure identified. The assessments cover such end-uses as lighting, heating, ventilation, and air conditioning (HVAC). The specialist develops energy conservation measures that are end-use specific based upon standard engineering analysis as well as cost estimates derived from experience or other similar projects. HMLP has structured the program so that the customer pays one third (1/3) of the cost of the assessment. The remaining two thirds (2/3) of the cost of the assessment will be paid for by HMLP. HMLP’s portion will range from $500 to $3,750.

HMLP offers a Commercial Lighting Retrofit Rebate Program to its commercial, industrial, and municipal customers that retrofit inefficient interior lighting systems, or convert outdoor lighting to Light Emitting Diode (LED). The lighting rebate applies to the retrofitting of existing:

  • T12 fluorescent lamps with magnetic ballasts to T5 or T8 lamps with electronic ballasts
  • T12 high output or high intensity discharge (HID) fixtures to T5 or T8 high output with electronic ballasts
  • Compact fluorescent lamp (CFL) exit signs with new Light Emitting Diode (LED), Electroluminescent, or Photo luminescent exit signs
  • High pressure sodium, mercury vapor, or incandescent outdoor lighting to LED
  • The installation of occupancy sensors – passive infrared and/or ultrasonic detectors only with no manual ON or override switches

HMLP caps the rebate amount at 50% of the project cost with a maximum of $4,000 per account. The rebate amount is credited to the customer’s account.

For more information about this program, call Energy New England at 888-772-4242 or email

Industry studies indicate that facility HVAC equipment represents approximately 31% of potential electric savings and 33% (over 2,000 kW) of potential Peak kW Demand reduction. An HVAC program has been developed by a Consortium for Energy Efficiency. HMLP’s HVAC program will be geared toward commercial/industrial customers who utilize roof top units (RTUs). The program will encourage customers to purchase high efficiency units for new applications or when replacing failed units. Rebates will be developed based on the tonnage of the unit as well as the efficiency. HMLP intends to develop a program similar to the Consortium’s “Cool Choice” program (details to be provided). Due to the technical nature of motors and HVAC systems, HMLP envisions creating the specifics of this program with the ENE specialists.

The HMLP reserves the right to change any portion of this program or end the program at any time without notice.
