EIA-860M. Planned capacity is the developers’ own schedule as reported to EIA each month; projects often slip or are cancelled.
The batteries already running on the U.S. grid against the pipeline due in the next year. When the planned line runs high relative to what is operating, a fast year of additions is queued up, if the projects arrive on time.
