The New Hampshire Heating Cost Problem
New Hampshire's rural character means many homes in the Lakes Region, Upper Valley, and Monadnock region have zero access to natural gas pipelines. These homeowners are paying $4,000–$6,000 annually for delivered oil or propane. Geothermal provides a permanent escape from deliverable fuel price volatility — and the NH Electric Cooperative offers some of the strongest geothermal rebates in the region.

New Hampshire Geology & Drilling Conditions
New Hampshire's White Mountain granite and metamorphic bedrock creates excellent conditions for standing column wells, particularly in the southern tier. Northern regions above the notches may require deeper drilling through more fractured formations. GDNE has drilled extensively across the state and understands the geological variation from the Seacoast to the Upper Valley.
