Key driver: Extreme grid saturation on O'ahu (HECO) limits new large-scale interconnection without storage; land scarcity on island; high existing rooftop penetration.
Permitting process
Local permitting pathway
CUP-M under Honolulu LUO for utility-scale. State Land Use Commission Agricultural or Conservation district boundary amendment often required.
Setbacks & buffers
LUO-based setbacks vary by zoning district. Utility-scale (>1 MW) requires Conditional Use Permit Major (CUP-M). Minimal undeveloped land for large-scale ground-mount on O'ahu.
Spacing requirements
None codified.
Size restrictions
Grid capacity is the primary restriction; HECO has limited O'ahu grid headroom for new utility-scale solar without storage.
Penalties & bonding
Total penalty: +5 (Denial +5)
State-level permits & approvals
CUP-M via Honolulu Department of Planning & Permitting (DPP) for utility-scale. LUC boundary amendment if reclassifying agricultural/conservation land. PUC/HECO interconnection agreement with RFP/RFI process. Chapter 343 HRS environmental review. FAA Part 77 coordination.
