"The utilities are going to shift to winter peaking faster than they realize," Thomas cautioned, explaining that between growing data center demands and decarbonization efforts, utilities are struggling to plan for near-term power needs. While geothermal solutions provide an answer to this problem, "Contractors want volume and stable work so they can dedicate a crew and put a truck on the road dedicated to Geo," Thomas explained. He described it as a "chicken and egg" problem. Contractors need enough consumer demand within a "50-60 mile radius" to justify investing in a geothermal specialty.

Thomas’s warning comes as grid planners forecast peak demand growth of 38 gigawatts through 2028, with data centers alone expected to account for 44% of U.S. electricity load growth from 2023 to 2028. 

"They really can't build power plants that fast," Thomas noted, suggesting this capacity challenge could drive renewed utility interest in ground source heat pumps, similar to the industry's momentum in the 1980s and early 1990s when utilities faced similar constraints.

Drilling Capacity Already Strained as Industry Faces Growth

The timing of this energy crunch coincides with significant industry challenges, particularly in drilling capacity. Terry Proffer, a geologist with Major Geothermal, highlighted the growing backlog in ground loop installation. 

"We can train engineers and mechanical contractors, but we need more people to put in ground loops," he explained. "We're already seeing that when you ask a driller in the Rockies, ‘can you do this next month?’ They’ll say, ‘this month next year." 

Proffer emphasized the urgency of the situation: "We've turned a corner, and now it's up to the industry to meet that demand, and we really need to take advantage of this momentum while we got it." 

However, promising developments are emerging in utility engagement. Stacy Kinnaly from the Geothermal Drillers Association pointed to the Framingham Project, a network geothermal neighborhood in Massachusetts launched in partnership between an environmental group and a utility.

"The fact that the gas utility was allowed to go ahead and transition to a thermal utility just opened up all sorts of doors," she noted, suggesting a path forward for community-wide adoption.

Manufacturers Unite Behind 'Mission Geo' Initiative

Major manufacturers, including WaterFurnace, Rheem, and Bosch, are coordinating through Mission Geo, a unified industry initiative. Michael Stevens of Bosch emphasized that OEMs are making "a sizable investment" in the program. 

"If you're not familiar with Mission Geo, it is an initiative that the OEMs are supporting ... we're trying to create that unified message and really get targeted after which stakeholders are important to talk about and talk to, both on the residential side and on the commercial side," Stevens explained.

Joseph Palomba, Vice President of Enterprise Applications at Rheem, stressed the importance of expanding beyond traditional industry circles. "What we need to do is start going off site and looking for the decision makers, knocking doors at engineering companies, in the architectural firms, in the home builders, and creating that demand," he explained. "It's going to be easier, from a manufacturers perspective, from the Association, from the contractor … to explain our products, explain our benefits."

The manufacturers are already planning a two-phase approach through Mission Geo. As Stevens detailed, "the initial focus of Mission Geo right now is to build the infrastructure that we need, and then transition to phase two of Mission Geo: to create awareness at the consumer level, on the residential and commercial side."

Thomas emphasized that "consumer awareness is still not where it needs to be," adding that the industry needs "more motivated consumers that have initiative that says, 'No, no, if you're not going to quote me Geo, then just tell me, because I've got more phone calls to make.'"

The potential for market expansion appears substantial, as ground source heat pumps currently represent only 1% of the heating and cooling market share compared to air source heat pumps at 13%. These systems also boast significant efficiency advantages – up to six to eight times more efficient than air source heat pumps in certain conditions.

Given the looming energy challenges and efficiency benefits, the industry stands ready to play a crucial role in addressing future utility constraints. Stevens encouraged industry participation in shaping Mission Geo's future: "If there's areas where you feel like we should be attacking, reach out to us ... give us some of that feedback so we can take that into the meetings."
