Willington committee weighs geothermal, PV and long-term cost forecasts as budget work continues
Summary
Committee reviewed budget updates and preliminary cash-flow forecasts for renovation vs. new-site options, discussed geothermal and PV trade-offs (geothermal ~ $3.4M before reimbursement), and asked the design and financial teams for detailed energy and tax-impact analyses.
At its June 22 meeting, the Willington School Building Committee reviewed updated budget summaries and preliminary cash-flow forecasts for options that include renovating existing facilities or building a new school on a different parcel.
Scott, the committee's consulting lead, presented two budget variants and preliminary cash-flow projections intended to help the town financial advisor model 20- to 30-year impacts. Scott and other members flagged geothermal systems as a high-upfront-cost option—the committee cited a preliminary all-in geothermal additional cost figure of about $3.4 million before reimbursement, including wells, contingency and design fees. Committee members noted the conversation changes markedly if a 93–95% reimbursement rate applies.
"When you take 93 or 95% of that, it's like a $200- to $250,000 cost," one member observed, describing net-town exposure after reimbursement. Another member who ran model assumptions (20-year bonds, partial eligibility assumptions and current heating costs) said geothermal could be net-positive from the start and yield nearly $500,000 in net benefit over 20 years under optimistic assumptions.
Members asked Tecton to provide projected operational savings, PV-system sizing (kilowatt assumptions), and an energy-use-intensity analysis using the town's utility bills so the committee and the public can compare options ahead of the public presentation scheduled for June 23. The committee agreed the presentations should include clear, comparable assumptions for capital cost, reimbursement percentage, and expected annual operational savings.
The financial advisor continues work on structuring potential debt and tax impacts; the committee anticipates preliminary tax-impact calculations and a fuller financial strategy in the coming weeks. The Chair emphasized the timeline goal: committee milestones are intended to support an October 6 referendum if the town moves forward.
Next steps: Tecton to model geothermal and PV scenarios with explicit kW and maintenance assumptions, the financial advisor to provide tax-impact scenarios for 20- and 30-year options, and staff to circulate the results to the committee and public before subsequent meetings.
