Developer outlook
Grundy County is a high-risk jurisdiction for utility-scale solar — documented ordinance hurdles are significant and approval history is mixed or unfavorable. Illinois's state RPS policy provides a supportive macro backdrop for renewables, even where individual county ordinances are restrictive. Market saturation is elevated in this area — expect competition for prime land parcels and interconnection capacity.
