Overview

GridPermit collects California residential solar and permitting facts directly from official sources (city, county, and state government sites, utilities, and public utilities commissions) and shows only what we can verify, with a confidence score and a link to where it came from. Nothing here is estimated or inferred beyond what's stated below. See our methodology for the rules this page follows.

Permit timeline

3–5 days

The City's own guide states: 'The GWP Solar Team typically completes the initial review of your PV Interconnection Application (and optional energy storage) within 3-5 business days. This review occurs before your application moves on to Engineering, Building & Safety, or both.' This covers only GWP's own initial interconnection-application review stage (Step 2 of 12); it does not include the separate Building & Safety plan review/permit issuance time (Steps 4-7) or the post-inspection NEM meter reprogramming time (7-10 working days, Step 11), which are not given as day-count figures in this guide.

Generation supplier

Glendale Water and Power (GWP) (utility)

GWP is a vertically-integrated municipal utility (like LADWP, Pasadena Water and Power, and Burbank Water and Power) — it generates/procures and delivers its own power rather than sitting alongside a separate CCA. No Community Choice Aggregator was found serving Glendale in the sources reviewed this session.

Directly re-verified via browser this session — the same 'Guide for Applying for PV Interconnection and NEM' page directly and comprehensively covers GWP's own interconnection/NEM process (PowerClerk application, Interconnection Agreement, GWP meter reprogramming), so is used for both permit_url and interconnection_url. An earlier, differently-titled 'guide-for-applying-for-interconnection' URL identified via search-engine indexing could not be independently confirmed to still exist and is no longer used.

Inspection steps

  • After installation, the solar contractor uses their Glendale Permits account to schedule the inspection with Building & Safety
  • After the inspection and final sign-off, Building & Safety notifies GWP Engineering that the system passed inspection
  • GWP Engineering then submits a work order to GWP Field Services for NEM reprogramming of the electric meter, taking 7-10 working days
  • Once the meter is reprogrammed, GWP notifies the contractor/customer that the system can be turned on

Per the City's own process guide, Steps 9-12.
