Requests for Interconnection for NEM, BESS, and Cogeneration Projects

In an effort to keep customers at the forefront of our mission to reduce carbon emissions and meet aggressive renewable energy goals, LADWP is committed to the continuous improvement of our Service Planning’s Interconnection process.

Collaborative changes to the interconnection process for NEM (net energy metering), BESS (battery energy storage), micro-turbine, fuel cell, and wind generation systems have been identified and are currently undergoing implementation. In support of those customers who have made the commitment to reduce their carbon footprint, changes to our online application and interconnection processes -- designed to save both time and money -- have been made and are highlighted below:

 

10kW and Below (1ø & 3ø)*

*If your project has an aggregate system size in in the range of 10kW or below (1ø), then your project will follow the Type 1 Interconnection Process, except in cases where a service panel upgrade is required or a multi-tenant dwelling can be found on the premises. If either of these prove true, then the project will follow the Type 2 Interconnection Process. If your project is 10kW or below (3ø), it will follow the Type 2 Interconnection Process.

  1. Determined by Nameplate rating as maximum continuous output power at unity power factor.

  2. For combined systems, please use the higher of the two values for aggregate size of PV inverters and aggregate size of BESS inverters.

  3. See Website for details and examples of sample photos.

  4. Pending example and sample of photos.

  5. Onsite Pre-Construction Meeting is available should the customer elect to have one. Otherwise photos and other documents will be used to complete this step.

  6. Required for New Construction/ADU projects only.

*If your project has an aggregate system size over 10kW and up to and including 30kW, then your project will follow the Type 1 Interconnection process. However, if a service panel upgrade is required, a multi-tenant dwelling can be found on the premises, or additional generation is connected to the customer’s service, the project will follow the Type 2 Interconnection Process.

  1. Determined by Nameplate rating as maximum continuous output power at unity power factor.

  2. For combined systems, please use the higher of the two values for aggregate size of PV inverters and aggregate size of BESS inverters.

  3. Small System IA required. Please check website for most current version. Older revisions will not be approved.
