Imagine a world where values and approaches align, where people and the environment are prioritized through strategic investments in energy infrastructure and technology that improve building performance, the quality of life of residents, and the bottom line. This is where Geosource Energy plays.
A leader in the North American geoexchange market, Geosource Energy is a relatively small second-generation Canadian operation that is having a significant market impact by providing Earth Powered Solutions™ to clients across North America and beyond.
Using geothermal energy, which is generated and stored beneath the Earth’s surface, the company’s geoexchange systems provide cost-effective and highly efficient heating, cooling, and hot water for new construction and retrofit projects that seek to set the bar for sustainability and performance.
Backed by proprietary technology and a unique approach, over its 20-plus year history Geosource Energy has drilled over six million linear feet for more than 400 successful projects across Canada and the United States, establishing itself as a leader in the field and a true champion of geothermal.
Why choose geothermal?
An investment in geothermal is an investment in reduced energy use, and thus, lower demand on the grid, fewer emissions, lower life cycle costs, more predictable monthly rates, and optimal year-round comfort; it’s a win for both people and the environment, which is why a greater number of utilities and government entities are doubling down on these investments.
Geothermal systems are proven more sustainable versus conventional HVAC systems, while also being more cost-effective over the long term. In fact, users can experience 25 to 50 percent lower energy costs as a result of the investment, while the underground infrastructure can outlast the structure itself. As CEO Stan Reitsma notes, studies have shown that, “For every dollar that’s saved there, there’s nine dollars saved on the grid.”
In a market marred by volatility and unpredictability, particularly where energy is concerned, the untapped potential of geothermal to add capacity to the grid is something worth exploring. Studies are underway to better understand how geoexchange systems can be used to support the grid as it faces unprecedented demand, particularly in the wake of mass data centre expansion.
Naturally, a big driver in the U.S. is from utilities as they seek to meet this growing demand—more specifically, they are investigating the role of geothermal in cooling storage and demand side power management for data centres as they continue to come online at an impressive pace. “If they can start proving out geothermal for data centres, that’s going to create a whole different type of expansion in the market,” says Vice President Kate Cheng, an area that Geosource Energy is prepared to undertake.
Why choose Geosource?
With more than 20 years of experience offering utility grade construction services and best-in-class drilling and expertise, Geosource Energy is not only a leader in geothermal but also a technology leader who sets the bar and continues to drive the industry forward.
“One of the big differentiators we have is our drill rigs. Geosource has worked with Novamac, our drill manufacturer, for many, many years now and we have only one type of drill rig that we use across our entire company,” says Cheng of the highly flexible dual rotary drill rig which enables work to be done in even the most challenging conditions.
Since 2008, Geosource Energy has been positioning the bore field below a building’s footprint, a proprietary process referred to as At Grade, which allows the drilling to take place before excavation starts (though it can come at any point during new construction or retrofits thanks to angle drilling). Angle drilling enables Geosource Energy to go beneath infrastructure like roadways, buildings, or greenspace without disturbance, using a central location and a concentrated workspace to minimize the impact of its operations.
“When you’re in urban environments drilling next to multifamily buildings with balconies five feet from where you’re drilling, we really limit the acoustic impact of our drill rigs and we’ve developed specialized equipment that allows us to containerize all of our operations so we’re not a big messy site with spoils and grout flying around in the air,” Cheng explains.
This enables the team to get maximum capacity from a limited area, which is particularly useful for retrofit projects like 240 Markland in the Greater Toronto Area, where geoexchange not only improved overall energy efficiency, but also reduced the property’s energy reliance.
“We try to limit the amount of space that we’re actually using to do the geo by putting them very close together at surface and then spreading it out underground,” explains Reitsma, who notes space requirements can be reduced by upwards of 95 percent. “If we had not angle drilled, they would not have been able to retrofit those buildings. They didn’t have enough space.”
This patent-protected process optimizes the trade sequence and drives value from a project’s outset, and to ensure that the benefits of its use are not limited by Geosource’s own capacity, which has been tested by growing demand, the company will license out the technology to other drillers to ensure that industry best practices are being implemented.
This drive to advance geothermal is part of the company’s DNA. According to Cheng, “Our core innovation tenets being equipment innovation, process innovation, and data-driven operations means design improvements based on real performance data, new tools for geothermal field analysis, and intelligence for operational systems,” which enables the company to undertake industry-leading projects that move the needle forward for geothermal and sustainable construction.
Setting the bar
Geosource Energy has a rich portfolio of projects highlighting the value it brings to the market. At the University of Toronto’s St. George campus, Geosource Energy drilled 372 boreholes at 250 meters per borehole (approximately half the height of the CN Tower) to complete the largest operational urban geothermal/geoexchange system in Canada. The project boasts an energy capacity with a storage equivalent of 250,000 electric vehicle batteries and it has cut greenhouse gas emissions by up to 17,000 tonnes annually.
The demonstrated value for institutional operations is incredible, which is why more and more such clients are integrating geoexchange into their projects. There is a desire to reap the long-term benefits, deemed worthy of their upfront costs.
This was also the case recently at the new Western Memorial Regional Hospital in Corner Brook, Newfoundland and Labrador where Geosource designed and installed the geothermal system, which included 375 boreholes spanning 600 feet below the parking lot. Recognized as North America’s largest hospital geothermal system, the geoexchange system provides 100 percent of the hospital’s heating, replacing electric baseboards with a more efficient system that has resulted in a 50 percent reduction in electricity use.
These are the kinds of results Geosource has delivered in Canada over its 20-plus year history, and now it continues to make history south of the border as well. Selected by Lendlease for the 1 Java Street project, a residential development in Brooklyn comprising 834 rental units—30 percent of which are designated as affordable housing—as well as nearly 13,000 square feet of neighbourhood-oriented retail space, Geosource’s expertise and ability to execute is in high demand, and for good reason.
Upon completion, 1 Java Street became the largest geothermal residential project in the United States, thanks to Geosource Energy’s vertical closed loop geoexchange system comprising 321 boreholes at a depth of 500 feet. This system will reduce annual carbon emissions from heating and cooling by 53 percent compared with typical residential systems and as an all-electric building, emissions will be eliminated.
This project also set the stage for additional work in the U.S. and as such, Geosource made the decision to establish a U.S. headquarters in Manhattan to support growth in demand.
For instance, Geosource recently partnered with Honeywell on the John F. Kennedy Elementary School project in Boston, the city’s first geothermal retrofit of a school in the area. Certainly, the geology of the area presents unique challenges, but Geosource was up to the task.
Cheng credits the rigs as “a big part of what makes us so flexible in different geologies because no matter what the geology is, we can tool up to do rotary drilling.”
It’s a good thing, too, because interest is being generated out west with other major projects like Oracle Global Headquarters in Nashville, which means neither geology nor geography is going to stop the company’s success.
The growing push for decarbonization
For clients, geothermal can serve as a component part of achieving net zero/low-carbon outcomes and Geosource Energy, with its acute awareness that only a percentage of the market has been spoken for, continues to push on.
“We all work together trying to decarbonize the industry and we have a solutions mindset related to that,” explains Cheng, which is why Geosource continues to experience growth in demand for its expertise around North America, and even the world.
According to Cheng, “We have the practicality and work ethic of a field-driven construction company but with the analytical approach of an engineering and technology organization.” This is backed by an unmatched depth of experience in the field, actionable data, and technology leadership that enables the company to find success no matter where projects may take it.
With interest even being generated overseas, where there is growing recognition of the potential impact of geoexchange, Geosource Energy is a Canadian company who has become a global authority in geothermal. This is a team that continues to advance the market through exceptional projects and unmatched performance, raising the bar for an entire industry in the process.
