Source: Rand, J. et al., Queued Up, Lawrence Berkeley National Laboratory, data through end of 2025. Compiled from the queues of the 7 ISO/RTOs and dozens of non-ISO utilities. A request is a proposal to connect, not a commitment to build: historically most are withdrawn. Capacity is the requested interconnection size; hybrids include the storage component.
