Planned transmission upgrades
9,999 transmission projects still to come — new lines, new and expanded substations, transformers and rebuilds — compiled from the seven grid operators' own published plans. Where a plan prices its projects, the open work adds up to about $113.2B. Upgrades near a site show up on the vet and in the site screen of the API. As of 2026-10-20.

Grid-operator plans list what transmission owners intend to build; dates slip and scopes change, so confirm a project's status with its owner. Interconnection network upgrades assigned to a specific new load are decided in that load's own study and are not in these plans.
