Note: Potential delays anticipated for some “new business” customer projects. PG&E is conducting accelerated safety inspections of electric infrastructure. This includes upgrading and strengthening our electric system in the highest fire-risk areas. As a result, interconnection projects requiring design, construction, or inspection through Service Planning may experience delays. Please contact the Electric Grid Interconnection (EGI) lead assigned to your project if you have additional questions.
