The Vermont Heating Cost Challenge & Geothermal Economics
Vermont's Comprehensive Energy Plan mandates net-zero greenhouse gas emissions by 2050. Because standard air-source heat pumps experience steep COP degradation during severe sub-zero cold snaps in the Green Mountains, geothermal is the premier engineering choice for full decarbonization without relying on fossil fuel backup or expensive electrical resistance strips.

Vermont Subsurface Geology & Bedrock Drilling Conditions
The spine of Vermont's Green Mountains is composed of metamorphic rock — schist, phyllite, gneiss, and bands of marble and quartzite. These crystalline rock units provide high structural integrity for open-loop standing column wells and vertical closed loops. Valley formations along Lake Champlain and the Connecticut River feature deeper glacial lacustrine clay and gravel overburden requiring steel casing down to bedrock refusal.
- Standing Column Wells (SCW): Strong in Green Mountain hard rock zones; hydrofracturing available for low-yield formations
- Vertical Closed-Loop Borefields: Universal; excellent performance in Champlain Valley and river terraces
