Grid development pipeline
National interconnection queue intelligence
Track 38,000+ interconnection requests and 1.86 TW of active queue capacity across ERCOT, PJM, CAISO, MISO, and other ISO/RTO regions — sourced from LBNL Queued Up and ISO filings.
What is the interconnection queue?
The interconnection queue is the pipeline of generation and large-load projects seeking grid connection. Queue depth, fuel mix, and withdrawal rates are leading indicators of where power infrastructure investment is heading — and where grid constraints may emerge.
