McKinstry presents solar pairing with roof projects; district could see multi‑million energy savings
Summary
Facilities staff and McKinstry presented three school‑site solar models tied to required roof replacements, estimating federal incentives and a 25‑year utility‑cost avoidance of roughly $7.2 million and net economic benefit depending on financing approach.
McKinstry, an energy‑services firm, presented to the Kenosha Unified School District facilities and finance committee on Nov. 1 how rooftop and ground‑mounted solar projects paired with scheduled roof replacements could reduce district energy costs over the long term.
John Sutter, the district's director of facilities, introduced the concept and said project timing was selected to align solar installations with necessary roof work at three sample buildings. Sean Curry of McKinstry described the company's guaranteed‑savings approach and said the firm models structural and electrical engineering as part of project proposals.
"We implement projects that have energy and operational savings. We guarantee those savings going forward," Sean said, explaining the performance‑contracting framework McKinstry uses to mitigate district risk.
Presenters walked the committee through three sample sites, describing expected offsets (one site modeled near a 90% offset, others lower) and the role of federal incentives. They noted a 30% federal investment incentive used in modeling and said project approvals and construction would need to meet the incentive program's completion window. Using conservative escalation and financing assumptions, presenters estimated a 25‑year avoided utility cost of roughly $7.2 million and a net economic benefit of $2.6–$4.1 million depending on whether the district funds projects with debt (using Wisconsin statute 66.0133 for energy‑savings borrowing) or pays from operations.
The committee asked practical questions about structural engineering and roof types. Presenters said the project cost model includes structural and electrical design and that switching to a fully adhered roof under panels can reduce ballast weight and structural stress. They also discussed limited direct utility financing; utilities may offer REC purchases or community solar programs but typically do not provide direct project financing.
Committee members asked about timing and risk if federal incentives lapse; presenters said some programs require approval or completion by a deadline and that they model projects conservatively to account for such uncertainties. The presentation closed with examples of nearby districts that implemented similar projects and a staff recommendation to investigate an engineering feasibility study as a next step.
Next steps: facilities staff plan to pursue a funded engineering study and return with refined cost estimates, structural assessments and financing options before seeking any board action.
