Working Group 4

About Rule 21 Working Group Four:  On July 13, 2017, the Commission issued an Order Instituting Rulemaking R.17-07-007 in order to consider a variety of refinements to the interconnection of distributed energy resources under Rule 21. Working Group Four will develop proposals to address four issues related to streamlining and improving the interconnection process, see the scoping memo. The four issues are:

  • Issue 18: Should the Commission adopt changes to anti-islanding screen parameters to reflect research on islanding risks when using UL 1741-certified inverters in order to avoid unnecessary mitigations? If yes, what should those changes entail?
  • Issue 19: Should the Commission adopt streamlined interconnection procedures (e.g. standard configurations eligible for expedited review) to facilitate the implementation of California Zero Net Energy building codes and, if so, what should those procedures entail?
  • Issue 29: Should the Commission establish a forum, either within this proceeding or externally to develop interconnection safety standards to address safety and environmental risks as the interconnection of distributed energy resources devices grows
  • Issue F: What interconnection rules should the Commission adopt to account for the ability of DERMS and aggregator commands to address operational flexibility need.
