Project Description

Amherst College is constructing a networked geothermal system to serve its entire campus, installing a 143-borehole field and approximately 10,000 feet of underground piping connected to the central energy plant.^1,2 The system replaces the college’s existing steam-based heating infrastructure with a low-temperature hot water network powered by ground-source heat pumps, serving 80 buildings and approximately 3,130 tons of cooling capacity.^2,8 The project is the centerpiece of Amherst College’s Climate Action Plan, which commits the institution to carbon neutrality by 2030.¹

Construction broke ground in March 2023. Phase 1, which included 10,000 linear feet of distribution piping and conversion of 10 buildings, was completed in fall 2023.⁸ Subsequent phases will continue building conversions and heat pump installation through 2029, with full campus steam retirement expected by 2030.¹ The project is expected to reduce carbon emissions by approximately 13,300 metric tons of CO₂ annually.⁸

Key Actors and Governance

The Board of Trustees formally approved the project in May 2022, with Chair Alison Overseth and President Kathleen McCartney providing institutional leadership.² Internal capital project managers Chris Tait and Daren Gray lead day-to-day oversight, supported by the Climate Action Task Force.⁴ Integral Group produced the 2019 Zero Carbon Energy Study that guided the campus energy transition, and Salas O’Brien serves as lead design engineer.^5,6 Additional partners include Haley & Aldrich, Berkshire Design, and C&H Architects.⁴

Funding and Costs

The Board of Trustees authorized approximately $80 million for the geothermal project, funded entirely through institutional capital.⁷ The new energy system will require an estimated $4.4 million every 17 years for infrastructure replacement.⁸ The college is pursuing IRA tax credits, including prevailing wage, domestic content, and energy community bonus credits, though specific dollar amounts have not been publicly disclosed.¹⁰

Unlike community-led or utility-led projects, Amherst College’s self-financing model bypasses the feasibility-to-construction funding gap that stalls many Massachusetts geothermal projects. A 30-year lifecycle net present value comparison found the geothermal system ($279M) less costly than maintaining the status quo ($340M).^2,10

Permitting and Approvals

The project requires a Board of Health geothermal well permit, wetlands permits related to Fearing Brook, and standard building, drilling, street opening, and railroad permits for subsurface infrastructure.^9,10 Agencies with oversight include the Amherst Board of Health, Conservation Commission, and local building authorities.¹¹ Despite initial delays in obtaining the drilling permit, key approvals have been secured and construction is proceeding on schedule.¹¹

Massachusetts law requires geothermal boreholes to be registered and all drillers to hold MassDEP certification.⁶ The Conservation Commission approved the project with conditions related to Fearing Brook wetland protection, and a well construction permit was issued in January 2026.^11,12

Community Engagement and Equity

Engagement has taken place through public hearings, planning board presentations, Conservation Commission hearings, and Board of Health proceedings, along with town committee updates and opportunities for public comment.¹² Local news coverage and college communications have informed the broader Amherst community.⁸ One concern documented in the public record involves potential impacts to wetlands and Fearing Brook, raised during Conservation Commission discussions.¹²

Equity and environmental justice are not central to the project’s stated rationale, which is framed around institutional decarbonization rather than community-serving infrastructure. Northampton’s January 2025 fossil-fuel-free building code update provides broader municipal policy context for the region.^5,13
