MOUNT PLEASANT — The Henry County Board of Supervisors held a work session Tuesday morning to review proposed ordinances for solar energy and battery storage projects. While no action was taken, the discussion outlined key concerns and potential changes as large-scale renewable energy development continues gaining traction.
Setbacks and Screening
Supervisors generally agreed that current setbacks—300 feet from homes, 50 feet from roads—are in line with other counties. They also discussed the 15-foot height limit on panels, with questions raised about whether it accounts for sun-tracking systems that tilt. Concerns about glare were addressed, though newer solar technologies appear to minimize reflection.
Zoning and Farmland Use
The board emphasized alignment with the county’s 2017 comprehensive plan, which prioritizes preserving high-value farmland and discouraging commercial development in rural areas. Supervisor Marc Lindeen expressed skepticism about converting row crops to solar, questioning whether it truly reduces carbon emissions long-term.
Residential vs. Commercial Systems
A 100-kilowatt threshold still marks the divide between residential and commercial projects, with larger systems facing stricter regulations. Supervisor Steve Detrick noted Access Energy lacks the infrastructure to support major commercial solar or battery storage developments.
Noise and Environmental Oversight
Supervisors discussed potential noise from transformers and tracking systems, referencing reports showing some units reaching 65–105 decibels—well above the county’s 45-decibel ordinance. They also stressed the need for DNR oversight on floodplain and drainage concerns, particularly for projects like a proposed 10,000-acre solar installation in the Green Bay Bottom.
What’s Next
The board tentatively scheduled another work session for 9:00 a.m. on August 15, inviting representatives from Access Energy and industry consultant Bruce Hudson to provide input. Supervisors want to ensure Planning & Zoning is on the same page before advancing ordinance changes.
