Documents LADWP asks for

• Interconnection application formOnline NEM portal application (www.ladwp.com/NEM) -> confirmation email with WR#; AIA cases: AIA Submission Information Form + shell application Gridpol prepares this.
• Photos (meter, main panel, equipment)Photos of service panel/existing electric service and installation area (Types 1-3)
• Interconnection agreement (when applicable)>10 to <=30 kW-AC: Short-Form/Small System IA (solar and/or ESS); >30 kW and all non-solar: Standard Offer Interconnection Agreement (SOIA)
• Single-line diagram (one-line) (when applicable)Type 2+ (>10 kW, panel upgrade, three-phase, multi-meter, battery): single-line diagram with system size and inverter specs Gridpol prepares this.
• Site plan / site layout (when applicable)Plot/site plan for Type 2+ Gridpol prepares this.
• Battery spec sheet (when applicable)BESS Technical Data Sheet if storage
• Load calculation (when applicable)Load Schedule if required (Types 1-2); required for Types 3-4 (>30 kW)
• Other utility-specific document (when applicable)Service Planning Information Form (Type 2+); Preliminary Review Approval (Type 4 if required); Solar Lease Compliance Form for leased systems; portal error screenshot for AIA
• Final inspection sign-offLADBS permit and final inspection approval; ESR verification for Type 2+

How the LADWP process runs

1. Submit online application with documents and photos at www.ladwp.com/NEM; apply for LADBS permit (Owens Valley/portal error: email AIA package to SolarCoordinator@ladwp.com, wait for approval, submit shell application with proxy address, send WR# within 7 business days)
2. Receive confirmation email with Interconnection/NEM Work Request number (WR#); pay Expenditure Recovery Charge(s)
3. LADWP review: ESR preliminary review/site visit and location drawing, engineer review (Type 2+), Interconnection Agreement approval ('OK to build')
4. Install system; LADBS final inspection; ESR final verification (Type 2+)
5. LADWP construction/testing as needed; crew installs net (and performance) meter
6. LADWP NEM Permission to Operate (PTO) notice by email; system must stay off/locked until then

Fees

Utility fees are paid by the installer or customer; they are not part of the Gridpol plan.

Size levels and limits

PV rated kW AC-CEC, BESS kW AC. Single-phase aggregate generation limited to 20 kW (inverter max output); larger must be balanced three-phase (feasibility study possible up to 40 kW at customer expense). NEM limited to <=1 MW.

Storage, EV and stamps

Common issues the utility lists

• AIA submittals not following all steps (one email per address, required subject line, error screenshot) are delayed or cancelled
• AIA request cancelled if WR# not provided within 7 business days of approval
• Non-compliance with LADWP Electric Service Requirements, local ordinances or electrical codes fails LADWP solar inspection

Gridpol’s pre-submission check covers these before we file.
