Breaking News! — DOE Report on GSHPs

Ground Source Heat Pump Mass Deployment reduces grid requirements by 33%!

U.S. Department of Energy’s latest report on the grid impact of ground source (geothermal) heat pumps provides a path to electrification without “breaking” the grid. Below are quotes from the report and a link for download.

• Even though building heating is electrified with GHP deployment—increasing winter electricity use for homes and businesses that otherwise are heated with fossil fuels—the increase is more than offset by the electricity savings from the high-efficiency performance of GHPs for summer cooling and reduced thermal loads owing to weatherization in single-family homes, resulting in substantial net reductions in grid generation, capacity, and transmission.

• The mass GHP deployment reduces transmission expansion requirements by 33% under the Grid Decarbonization scenario and by 38% under the EFS scenario. This amount equates to roughly 24,500 mi of transmission that can be avoided under the Grid Decarbonization scenario and nearly twice as much (43,500 mi) under the EFS scenario, which is enough to cross the average contiguous US coast-to-coast distance 9 and 16 times, respectively.

NOTES: “GHP” is “Geothermal Heat Pump”, one of the terms used for Ground Source Heat Pump or Geothermal Heat Pump technology. “EFS” is “Electrification Futures Study”.

IGSHPA Announces 2024 Membership Program!

As IGSHPA continues to grow and provide more benefits to members, we occasionally need to review our membership program to ensure that it is fair to all members, it is positioned to help the organization and the GSHP industry grow, and it is easy to understand.

We have spent the last two years discussing the current membership program with members and the IGSHPA board of directors. We are excited to present a new membership program, effective January 1, 2024, that will put IGSHPA on a new path for growth and provide members with many more choices to participate. It will also help correct some of the confusion with membership and certification, and provide discounts for members, as well as additional incentives. IGSHPA’s last membership cost increase was in 2016. This new program will have very little financial impact on members but will provide a much better program for IGSHPA and members long-term.

Below is a summary of changes for 2024. You can find all of the details in the new membership brochure or online at our membership page.

  • Individual IGSHPA membership has stayed the same as 2016 at $125 per year.
  • Certification renewal for members for AI (Accredited Installer), CGI (Certified Geothermal Inspector), and CRD (Certified Residential Designer) decreased from $100/year to $75/year. Overall cost for membership plus certification renewal increased by $50/year for members. For non-members, the overall cost for membership plus certification renewal increased by $100 per year. Note that CGD (Certified GeoExchange Designer) certification is administered by AEE (Association of Energy Engineers) and therefore certification renewal and AEE membership has not changed.
  • HVAC, GHEX, and other contractor memberships increased by $30 per year.
  • A new directory only listing (no membership or voting) has been added for contractors, distributors, and MEP firms at $200 per year. This is a new level to encourage more industry participation and help customers find GSHP businesses in the online directory.
  • Utility memberships have been broken out separately (previously part of manufacturer memberships) as distribution co-operatives, municipal utilities, G & T co-operative utilities, Investor-owned utilities, and (Canadian) Crown corps.
  • Distributors and MEP firms memberships increased by $230 per year. This is part of our efforts for membership fairness, better leveling out the membership types.
  • A new student/retired individual membership has been added.
  • A new community organizations membership (trade schools, community colleges, university departments, government, and state provincial associations) has been added.

If you have any questions at all, please contact us at , 1-800-626-4747, or 1-217-212-2112. Thank you for your support of IGSHPA!

2024 Kirk T. Mescher Innovation Award

The Kirk T. Mescher Award was established in 2015 after the tragic loss of one of the brightest and most innovative professional engineers, Kirk Mescher of CM Engineering. Kirk had the courage to implement his innovative ideas and was fearless in the pursuit of making his designs work better, simpler, and more efficiently.   He was always pushing the envelope.   Kirk was very active with ASHRAE, serving as a Director-at-Large on the ASHRAE Board of Directors just prior to his passing. It is for these reasons that the ASHRAE St. Louis Chapter gives an award of $3000 in Kirk’s name each year.  The deadline for 2024 applications is Sunday, January 7, 2024.

NGWA Headquarters spotlight available

NGWA (National Ground Water Association) broke ground on a geothermal retrofit at its headquarters on August 22, 2023, in Westerville, Ohio. Utilizing the geothermal tax credits available for nonprofit organizations that were signed into law in 2022, NGWA is replacing 9 furnaces, 9 air conditioners, and a mini split with 9 geothermal units. Ductwork and other modifications will be made to improve comfort and better utilize the building’s HVAC system. Many industry stakeholders came together for this renovation, including IGSHPA and NGWA members and suppliers of equipment, pipe, and other system components. An IGSHPA member engineering firm even provided discounted pricing for design of the system. This project is a great example of how retrofit applications can work well and be good business for well water and geothermal contractors, engineering firms, and building owners.
