Getting Started with NH Thermal Renewable Energy Credits (TRECs)

House_w_geoGround Energy Support (GES) offers comprehensive services for owners of geothermal heat pumps in New Hampshire to begin metering and reporting renewable thermal energy. A 6-ton heat pump providing a typical 2,500 hours of heating will generate approximately $625 worth of Thermal Renewable Energy Credits (TRECs) annually. TRECs are new to New Hampshire and will also soon be added to Massachusetts Alternative Energy Portfolio Standard as well.

Below is the detailed step-by-step process for New Hampshire homeowners to take advantage of this opportunity, including the costs associated with each step.

Step 1

Confirm your system's eligibility.

Geothermal heat pump systems in New Hampshire that began operation after January 1, 2013 are eligible to receive TRECs.

Step 2

Install a meter.

For systems with capacity less than than 16.6 tons, TRECs can be calculated using heat pump runtimes and published performance data. We offer the GxTracker-Basic, starting at $395. Installation of a GxTracker-Basic typically takes one to two hours, costing approximately $200.

For large systems, a heat meter is required and we can assist you in specifying a heat meter that will be suitable for reporting TRECs. See other metering options for a more detailed discussion and flow chart.

Step 3

Retain an Independent Monitor.

An Independent Monitor is required to conduct an initial inspection of the system to confirm compliance with the TREC requirements and then report measured thermal energy monthly to the New England Power Pool Generation Information System (NEPOOL-GIS) database. GES charges a one-time flat fee of $120 for a residential on-site inspection and a $60 annual fee for reporting data to the NEPOOL-GIS.

To retain GES as your Independent Monitor, complete this Independent Monitor Agreement and email to: info@groundenergysupport.com or fax to: (603) 374-8091.

Step 4

Schedule a site inspection.

Contact GES to schedule a site inspection. During the inspection, GES personnel will confirm the heat pump and metering equipment meet the requirements of the TREC program and provide the required stamp of a Professional Engineer, at no additional charge.

Step 5

Register with NH Public Utilities Commission (NH PUC).

At no additional charge, GES will assist homeowners in completing the application to register their system with the NH PUC and will submit the application to NH PUC on behalf of the homeowner.

Step 6

Report and sell TRECs.

Once approved by the NH PUC, GES will report your renewable energy production to the NEPOOL-GIS. Ongoing reporting carries an annual fee of $60. We recommend that residential users retain the services of an Aggregator to sell their TRECs. Aggregators typically charge a 10% commission on the sale of TRECs. GES can assist you in locating an Aggregator.

For a residential system with a single heat pump, the total upfront costs are approximately $800, with an ongoing annual cost of $60 for reporting and an approximately 10% commission fee for selling the TRECs.

  • Our Mission

    Ground Energy Support strives to provide high quality data and objective analyses to support the ongoing development of ground source heat pump technology.
  • What customers say:

    • Your system has been absolutely crucial in helping me monitor problems as they occur, right at my fingertips. Doing without it would be like driving a car without any gauges. - Pete W., Homeowner
    • It is interesting to follow the data and understand what the system is doing. …Love this information, wish I had known about it before – I am really glad I installed it. – Steve H., Homeowner
    • I look at it every day! -- Paul B., Homeowner
    • I did not know that my oil heat circulator was cycling on every 6 hrs until this monitoring showed me that. Why add heat 4 times a day in summer?! I turned it off after GES alerted me to what was happening.” Pete Tavino, P.E., IGSHPA Instructor
    • I have been checking the GxTracker, and noticed that the total heat rejected was less than it should be. I checked it out and the machine was a little low on refrigerant so I recharged it. I checked the website and system efficiency improved by almost 40%, cool! -- John S., Geothermal Professional
    • We just ran the AC for first time last night … Pretty cool to see all the data! -- Greg M., Homeowner
    • Well, more “kudos” to Ground Energy Support. I just got a call from my installer who will address this issue. Again, thanks so much for everything. --Joseph P., Homeowner
