Waiver of “Significant Transmission Project” Status
Table 1 and 2 update the planned transmission and generation projects, respectively, in PG&E service area that were presented in PG&E’s 2012, 2013, 2014, and 2015 Annual Progress Report. These projects were granted the waiver of “Significant Transmission Project” status for the purpose of Project Coordination Review Process.
Table 3 and 4 list the planned transmission and generation projects, respectively, in PG&E service area requesting waiver of “Significant Transmission Project” status. The purposes of these projects are for serving local load, to enhance or maintain local reliability, and/or to reduce local capacity requirements. These projects are not expected to have significant impacts on the operation of the Western Interconnected System. PG&E requests waivers of the “Significant Transmission Project” status for the purpose of Project Coordination Review Process.
