Summary
McClure briefed the board on phase‑1 completed work, a planned HVAC summer schedule and an amended plan to add solar under a power purchase agreement; the contractor said utility rate changes and roof conditions affected the original savings projection.
Representatives from McClure updated the Caroline County School Board on an energy‑performance contract that includes building efficiency work completed in phase 1 and a proposed solar power purchase agreement (PPA) to capture additional savings.
Chris Stoltz and Christy Sherif of McClure briefed the board that lighting and building‑envelope work are complete and that the next construction focus this summer will be HVAC work, primarily at Caroline High School and Caroline Middle School. The McClure team described a revised solar plan: interconnection applications for roof‑mounted arrays at the original three schools were approved at resized capacities after coordination with the local utility, Rappahannock Electric Cooperative (REC), and McClure said it is negotiating PPA terms and an amendment with Virginia Energy.
Why it matters: The energy project was originally projected to deliver roughly $108,000 in annual utility savings (approximately $3.3 million over 20 years) for the three primary buildings. McClure told the board utility rate structures and incremental usage data required array resizing and altered the projected savings; McClure proposed advanced recommissioning (adjusting building control sequences and start‑up procedures) and expanding the program to two additional elementary schools to recoup savings.
Key technical and financial points presented: - Interconnection: McClure reported approved interconnection at revised sizes and said PPA details are being finalized with Virginia Energy and the local utility. - Savings: Revised projections showed about $84,500 annual savings for the original three schools with advanced recommissioning (about $2.9 million over 20 years). Expanding to five schools raised estimated savings to about $115,000 annually (about $4.0 million over 20 years) in McClure’s scenarios. - Recommissioning: McClure emphasized “demand‑shift” opportunities revealed by 10‑ to 15‑minute interval utility data. By aligning building energy use with solar production windows and modifying start‑up sequences, McClure said the division could increase net savings without upfront capital from the district. - Roofs and scope limits: Facility condition assessments flagged roofing issues at Bowling Green and Madison elementary schools, which limited immediate solar deployment there without roof repairs; McClure suggested the roofing work be integrated into future amendments if the board chooses to expand. - Contract model and risk: McClure described the PPA as having no upfront cost to the school division; the PPA would set fixed per‑kilowatt‑hour rates and include production guarantees. McClure said such agreements insulate the district from volatile market spikes for the contracted portion of power.
Board concerns and clarifications: Board members asked whether McClure would cover any shortfall versus earlier guaranteed savings. McClure said the existing performance contract did not include solar or the advanced recommissioning scope and therefore did not obligate McClure to absorb differences for work outside that original scope; McClure said it nonetheless is working to recover as much of the original projected savings as possible through recommissioning and potential program expansion.
Schedule and next steps: McClure said it aims to finalize PPA amendment language and scopes for the original three schools by the board’s next meeting and to begin procurement and installation to get arrays online in early 2026, noting interconnection timelines are governed by the utility review process.
