Your Home Energy Audit is more comprehensive than before, to schedule the audit please call 1-888-772-4242.

Tier 1 and 2 services: We will continue to offer the Tier 1 and 2 services as described by the Massachusetts Department of Energy Resources. Customer Specialists at Energy New England will answer customer inquiries concerning energy savings measures they can enact to lower their electric bills. The customer can also request an energy audit which the HMLP provides free of charge through ENE. The 1st improvement in our new HMLP IS GOING GREEN program is in the home energy audit area. We will now perform an infra-red inspection of the customer's home as part of the audit. This inspection will help determine where such money-saving interventions like: is insulation needed, will caulking could seal costly cracks, whether a window or door needs to be re-glazed or whether there's a need for window replacements.

LED bulbs are available at our office

Lighting:The HMLP has had several energy efficient lighting programs with Light-Emitting Diode (LED) bulbs that have included our subsidizing discounts at local stores, distributing free bulbs at our office, giving them to several groups at the Senior Center, sharing them with Hingham students at various educational outreach programs and have made them available to participants at the Hingham Family Fun Day. The HMLP will continue to find opportunities to encourage its customers to use LEDs. We can increase their usage by working with our customers when they purchase a bulb and by our continued promotions with give-aways as a method of introducing the benefit of a LED to our ratepayers.

We've added additional appliances & raised the rebate amount you'll receive for purchasing efficient appliances

Appliance Rebate Appliance Rebate Program: HMLP's Appliance Rebate Program gives residential customers a rebate for purchasing energy efficient appliances (Energy Star rated). The following appliances are eligible for the rebate program:
  • Refrigerator $25 (Old refrigerator must be taken away);
  • Clothes Washer $25;
  • Central A/C (SEER >=16.5) $50;
  • Dehumidifiers $25;
  • Thermostat/s (Smart WI-FI Enabled) $100;
  • Programmable Thermostat/s $50;
  • Heat Pump Water Heaters (AHP - Air Source Heat Pump) $500;
  • Ductless mini-split (see program) $500/ton with a $2000 cap;
  • Duct AHP; (see program) $500/ton with a $2000 cap
  • A rebate for solar installations

    Solar: The HMLP will offer a rebate in the form of check (effective January 1, 2021) to customers who install and own a photovoltaic system at their homes in Hingham. The amount of the rebate will vary according to the capacity of the photovoltaic system. There is a cap of $6000 per account. The HMLP will rebate $0.06/W x the rated output of the system or $6000, whichever is less. For example, an HMLP customer who installs a photovoltaic system at their home in Hingham and whose system has a rated output of 2.5kW will receive a rebate check for $1500. If that same customer installed a system with a rated output of 10kW, they would receive a rebate check for $6000. If they installed a system with a rated output of 5kW they will receive a rebate check for $3000. Additionally, HMLP has partnered with the Commonwealth of Massachusetts Department of Energy Resources (DOER) for an additional rebate. The DOER will, for as long as funds are available and the system meets DOER design criteria, offer rebates in the form of a check. The DOER rebate is equal to $.60/W x the design capacity output of the system with a cap of $6000 on installations up to 25 kW less.

    Financial help for weatherizing your home

    Home Weatherization: The HMLP will offer a rebate of 50% with a cap of $1000 per account in the form of a rebate for customers who are electric heat customers or who have central air conditioning and make certain energy efficiency improvements in their existing Hingham homes. Weatherization work as a part of new construction is not eligible for a rebate. Additions on existing homes are considered new construction. To apply for a rebate in the form of a credit on their bills the HMLP residential customer should arrange through ENE for an energy audit. Eligible improvements must come recommended in the audit and have a payback of less than 10 years to qualify for a rebate. Improvements which are eligible include:
  • Attic, wall, floor or crawlspace and rim joist insulation
  • Air sealing measures such as weather stripping, caulking, interior storm windows If a homeowner does the work themselves they should save all receipts for materials associated with the installation. A dollar value for self-labor is not eligible for a rebate.
  • Commercial properties can now receive Energy Audits that will cover lighting and HVAC equipment, to schedule the audit please call 1-888-772-4242.

    Energy Audits:HMLP has contracted with certified commercial and industrial specialists (ENE) to provide an energy management study and then develop a plan of action for each energy conservation measure identified. The audits cover such end-uses as lighting and heating, ventilation and air conditioning (HVAC). The specialist develops energy conservation measures that are end-use specific, based on standard engineering analysis, cost estimates derived from experience and similar projects as well as designed to improve or maintain existing comfort and lighting levels. The HMLP has structured the program so that the customer pays one third (1/3) of the cost of the audit and the HMLP picks up the remaining two thirds (2/3). HMLP's portion will range from $500 to $3,750.

    Rebates for those commercial customers who retrofit inefficient interior lighting systems or convert their outdoor lighting to Light Emitting Diode (LED)

    Lighting System Rebate Lighting: The HMLP would offer a Commercial Lighting Rebate program to its commercial, industrial and municipal customers. The lighting rebate applies to the retrofitting of existing
    1. T12 fluorescent lamps with magnetic ballast to T5 or T8 lamps with electronic ballasts
    2. T12 high output or high intensity discharge (HID) fixtures to T5 or T8 high output with electronic ballasts
    3. New Light Emitting Diode (LED), Electroluminescent, or Photo luminescent exit signs that replace incandescent or compact fluorescent lamps (CFL)
    4. And the installation occupancy sensors - passive infrared and/or ultrasonic detectors only with no manual ON or override switches
    5. High pressure sodium, mercury vapor, incandescent outdoor lighting to LED
    The HMLP would cap the rebate amount at 50% of the project with a cap of $4,000 per account. The rebate amount will be credited to their account

    Commercial customers who replace inefficient HVAC systems will receive a rebate

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