Summary
The finance committee approved an amendment to add borrowing for a solar array at the municipal water treatment plant. The committee and staff said federal tax credits (estimated at 30%) and potential grants could substantially reduce net city cost; the motion passed and staff will proceed with design and grant pursuit.
The Common Council Finance Committee approved an amendment to add borrowing for a municipal solar array at the water treatment plant, with the motion calling for $2.5 million in authorized borrowing and direction that any grants or tax-credit proceeds be used to reduce outstanding debt.
Alder Henke moved the amendment; Alder Watson seconded. Committee members discussed project timing, grant and tax-credit uncertainty, and upfront design costs. Staff said they expect a 30% federal investment tax credit could apply, an additional 10% bonus may be possible for certain domestic content, and grant awards remain uncertain until decisions expected in the spring.
Staff estimated design and bid preparation costs of roughly $100,000–$150,000 that the city would pay up front and potentially reimburse from borrowing later. Finance staff said, if constructed, the debt retirement for an unsubsidized $2.5 million general-obligation borrowing would be about $300,000 per year over 10 years beginning in 2027; those numbers would fall if tax credits or grants were applied to the city’s share.
Committee members said the project is one piece of a broader strategy to stabilize water rates over time; the committee approved the borrowing amendment and instructed staff to pursue grants and tax credits and return status updates to finance and infrastructure committees.
The committee also discussed procurement timing, panel availability and the importance of moving forward before certain tax-credit deadlines that may affect project economics.
