Site Control Compliance Blog

Practical guides on FERC Order 2023 site control compliance, RTO coverage thresholds, and interconnection queue risk management.

FERC Order 2023 replaced the patchwork of RTO-specific site control rules with graduated, stage-aware thresholds. Developers must now prove eligible instrument coverage at every queue milestone — from application through IA execution. These articles break down the per-RTO rules, instrument eligibility, option-to-lease conversion timelines, encumbrance exclusions, and the coverage math that determines whether your package passes or fails. Whether you're filing in PJM, MISO, CAISO, ISO-NE, NYISO, or SPP, start here. For quick answers, see our FAQ.
