Interconnection queue in the USA — page 23

Before a new power plant or battery can connect to the US grid, it joins a queue for studies and an interconnection agreement. Most requests never get built. This shows every request: active, built and withdrawn.

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 A request is a proposal to connect, not a commitment to build: historically most are withdrawn.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.
