Interconnection-queue requests filed here (last two years)
Requests to connect generation or large loads, as the ISO/RTO publishes them. Filing is an application, not a commitment to build.
No dated queue filings for this county in the files we ingest (some ISOs don't publish a county or filing date).
Local impact
Water, on-site generation and air permits, incentives, regulatory events and large-load tariffs, where a source documents them. Counts are of sourced records, not of the state's totals.
