Jefferson County County, TN — Solar Development Risk Assessment

Local solar ordinance barriers, board sentiment, and utility policies that affect development timelines and risk.

59
Risk Grade
Poor
Jefferson County scores C-high (Risk 48.35) because the 2023 ordinance with 750 ft setbacks represents a substantial compliance barrier, the political trajectory is clearly worsening as Knoxville exurban growth brings more anti-solar residents, and the withdrawal of multiple large proposals confirms that real-world development difficulty has increased sharply since 2022.

Board Sentiment & Political Risk

Sentiment Analysis
Resistant — Douglas Lake retirement and recreation community is politically active against utility-scale solar; Appalachian Electric Cooperative territory; growing Knoxville exurban population brings similar anti-industrial-solar suburban sentiment; county commission adopted 2023 ordinance in response to organized opposition
Basis for Assessment
Jefferson County is experiencing rapid growth as a Knoxville exurb (Dandridge area); Douglas Lake is a major recreation/retirement destination whose residents organize politically against utility-scale solar; the 2023 ordinance adoption reflects a county commission that responded to organized opposition by substantially raising barriers; East Tennessee anti-solar network influence is strong
