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.

Battery/solar incentive program on record

PWP Residential Solar and Battery Rebate Pilot Program - Battery Storage Track

Battery energy storage incentive of up to $550/kWh for residential customers, part of a pilot program launched April 7, 2026. No funding cap or end date stated in the source.

Status on file: active. Verify current status before relying on this.

Confidence: High (0.85)

Permit fees

  • Self-Generation/Interconnection Application Fee (GFIA): $800 (flat)

    Check payable to 'City of Pasadena'. Additional fees may apply if a supplemental review or detailed interconnection study is required (amount not specified by source).

  • Plan Review and Inspection Fees: $0 (flat)

    PWP states it is not charging plan review and inspection fees for solar and battery systems. Structural, Building & Safety, meter, and other non-energy-related fees may still apply. The relationship between this waiver and the separately-stated $800 GFIA application fee above is not fully reconciled by these two source pages — confirm directly with PWP before treating both as simultaneously accurate.

Generation supplier

Pasadena Water and Power (utility)

PWP is a vertically-integrated municipal utility, not layered with a separate CCA. Per PWP's own materials: about 10% of power demand is met by PWP-owned generating facilities; the remainder is purchased via contracts (conventional and renewable) and the wholesale energy market. No Community Choice Aggregator was mentioned anywhere in PWP's own materials reviewed this session.

Interconnection

https://pwp.cityofpasadena.net/selfgenusp/

PWP's own self-generation/interconnection requirements page. Content directly confirmed, including the full application process — no bot-blocking encountered on pwp.cityofpasadena.net this session, unlike pge.com/sanjoseca.gov/fremont.gov in prior records.

Confidence: High (0.9)

Permit authority

City of Pasadena Department of Planning & Development issues the building permit; Pasadena Water and Power's interconnection approval is required first, before a building permit application can be submitted.

Distinguishes the two authorities per this record's collection rules: PWP is the interconnection authority (and the utility itself); the City's Planning & Development department is the separate building-permit-issuing authority. No City of Pasadena Planning & Development page was independently fetched this session — this fact comes from PWP's own description of the process.

Required documents

  • Completed GFIA (Generation Facility Interconnection Application) Form
  • Site plan with system description and parameters
  • Single line diagram of electrical components
  • Certification test verifying equipment compliance
  • Signed contractor agreement (required when: if available)

Inspection steps

  • Submit application package (GFIA form, site plan, single-line diagram, certification test, contractor agreement if available) to PWP Customer Relations - DG Applications
  • PWP reviews and determines if simplified interconnection or a detailed study is needed
  • PWP issues an approval letter (required before applying for a building permit)
  • Sign the applicable GFIA Interconnection Agreement (separate forms for systems above vs. below 15 kW)
  • Obtain a building permit from the City of Pasadena Department of Planning & Development
  • Install the system and schedule fire/building inspections
  • Submit a 'Permission to Operate' request with final inspection documentation
  • PWP performs a field inspection and meter replacement, then issues the 'Permission to Operate' letter

This is PWP's full 8-step interconnection-to-operate sequence, not a narrower 'inspection only' list, because PWP's own material presents it as one unified process with the building-permit step (step 5) embedded partway through.
