*All system size ratings submitted as kW AC (battery) and kW AC-CEC (solar).
Type 1, 2, 3 and 4 Interconnection Process.
Type 1 – PV (NEM)/BESS
Customers or contractors can apply under the Type 1 Interconnection Process for PV (NEM) and/or BESS projects that meet the following Service Planning requirements.
Type 1 Interconnection Process should be followed if the proposed system is up to and including 30kW* aggregate system size* and does not include:
1) a service panel upgrade;
2) a three (3) phase service connected to the customer’s project;
3) projects that contain any non-NEM eligible cogeneration components; and
4) other multi-meter interconnection types such as apartment buildings, tract home projects, etc. (e.g. multi-meter interconnections are not “single meter” interconnection applications).
Type 1 Interconnection Process will typically involve these steps:
*Note: Additional LADWP solar programs information is available on the Solar Programs page.

Type 2 – PV (NEM)/BESS/COGEN
Customers or contractors can apply under the Type-2 Interconnection Process for PV (NEM) and/or BESS projects that meet the following Service Planning requirements.
Type 2 Interconnection Process should be followed if the proposed system is up to and including 30kW* aggregate system size* (or 10kW and below, 3 phase) and does include:
1) a service panel upgrade; and/or
2) other small multi-meter interconnection types such as apartment buildings, tract home projects, etc. i.e. not a single meter interconnection application and/or
3) projects that contain any non-NEM eligible cogeneration components up to and including 30kW* aggregate system size.
Type 2 Interconnection Process will typically involve these steps:

Type 3 – PV (NEM)/BESS/COGEN
Customers or contractors can apply for the Type 3 Interconnection Process for PV (NEM), BESS and/or Cogeneration projects that meet the following Service Planning requirements. All system size ratings submitted as kW AC and kW AC-CEC (solar).
Type 3 Interconnection Process should be followed if the proposed system installation is greater than 30kW* and less than 1MW (for NEM and BESS) aggregate system size, for all non-NEM eligible cogeneration project greater than 30kW* and less than 1MW aggregate system size, and/or does include:
1) a part of a new tract home project (i.e. five or more homes being interconnected);
2) a three (3) phase service connected to the customer’s project with aggregate system size* greater than 10kW*; and
3) other large, multi-meter interconnection types such as apartment buildings, tract home projects, etc. i.e. not a single meter interconnection application.
Type 3 Interconnection Process will typically involve these steps:

Type 4 – COGEN ONLY
Customers or contractors can apply for the Type 4 Interconnection Process for PV, BESS and/or Cogeneration project that meet the following Service Planning requirements. All system size ratings submitted as kW AC and kW AC-CEC (solar), as applicable.
Type 4 Interconnection Process should be followed If the proposed installation is greater than 1MW (for PV and BESS) aggregate system size*, for all non-NEM eligible cogeneration project greater than 1MW aggregate system size.
*Sum total of all forms of customer owned generation on-site. Example: For inverter-based generation, the sum total of (if applicable) all non-solar dedicated inverter nameplate ratings (kW AC), or kW AC-CEC (solar) values.
Type 4 Interconnection Process will typically involve these steps:
