About this data

For each analysed line section, PG&E reports the largest load, generation and solar project that could connect without upgrades, the criterion and hours that limit each, and whether PG&E expects it to fail Screen L. Sections on one feeder share the feeder's capacity, so the values should be counted or ranked, never summed. Storage needs room both ways, so its capacity is the smaller of load and generation.

What people use it for

  • Find line sections that could take a project of a given size
  • Compare hosting capacity across a PG&E area
  • See what limits capacity at a location
