BELLINGHAM, Mass.— Dandelion Energy and Woodland Peak Development have partnered to incorporate geothermal heating and cooling systems into Whitman Acres, a new 15-unit all-electric townhome community in Bellingham, marking another step forward in the growing adoption of geothermal technology in residential construction.
The project will bring geothermal systems to all 15 townhomes across five buildings, creating a community designed around energy efficiency, lower operating costs, and reduced environmental impact. The development was made possible in part through new construction market transformation rebates offered by National Grid through Mass Save®, Massachusetts’ statewide energy efficiency program.
The collaboration reflects a broader industry shift toward electrification and high-performance homebuilding as developers seek alternatives to conventional heating and cooling systems that can improve homeowner comfort while reducing energy consumption.
“Geothermal has long been the best way to heat and cool a home, but the missing piece has been making it work economically for builders,” said Dan Yates, CEO of Dandelion Energy. “What we’re doing with Woodland Peak and builders across the country is proof that we’re there. When Mass Save rebates, production-scale deployment, and a committed builder come together, geothermal stops being a premium option and starts being a standard one.”
Whitman Acres represents the latest example of Dandelion’s effort to scale geothermal deployment in new residential construction. The company specializes in integrating geothermal systems into production homebuilding through a streamlined design and installation process intended to reduce costs and simplify implementation for developers.
Unlike conventional air conditioning systems or air-source heat pumps, geothermal systems use underground piping loops to access the earth’s stable subsurface temperatures. The technology provides year-round heating and cooling while maintaining efficiency during periods of extreme weather.
According to Dandelion, homeowners at Whitman Acres can expect significantly lower energy costs, quieter operation, reduced maintenance requirements, and system lifespans exceeding 25 years. The company estimates geothermal systems can reduce energy bills by as much as 50 percent compared to traditional heating and cooling technologies.
“Woodland Peak is constantly looking for ways to stay ahead of the curve, and geothermal is by far the highest quality heating and cooling anyone can bring to a new home,” said Ernie Feiteira, Founder and CEO of Woodland Peak Development. “Partnering with Dandelion allows us to elevate Whitman Acres by offering a premium, reliable, and exceptionally quiet system without additional costs or complications to our construction timeline.”
Beyond benefits to homeowners, proponents of geothermal technology point to its potential impact on electric grid reliability. Because geothermal systems require less electricity during peak heating and cooling periods, they can help reduce strain on the grid during periods of high demand.
Dandelion estimates geothermal systems use approximately 25 percent less energy during peak summer demand and 65 percent less energy during peak winter demand than conventional alternatives.
“As we continue to explore ways to save ratepayers money, technologies like geothermal are leading the way,” said Melissa Lavinson, Executive Director of the Office of Energy Transformation. “The savings don’t stop at the front door. By decreasing demand on the grid, especially during the hottest and coldest days of the year, geothermal can deliver ratepayer-wide savings now and in the future.”
National Grid officials said the project aligns with broader efforts to support innovative energy technologies and improve long-term affordability for Massachusetts residents.
“As a Sponsor of Mass Save®, National Grid is proud to support this project, advancing the development of residential geothermal technology,” said Amy Vavak, Director of Massachusetts Customer Energy Management at National Grid. “This investment will lower energy and maintenance costs, help reduce energy bills, and advance long-term sustainability goals for Massachusetts.”
The Whitman Acres development follows Dandelion’s recent partnership with Lennar to deploy geothermal systems in more than 1,500 new homes in Colorado, one of the largest residential geothermal initiatives undertaken in the United States. The company is currently working with builders nationwide as interest in geothermal heating and cooling continues to grow among developers, utilities, and policymakers seeking scalable solutions for energy-efficient housing.
