Integration Capacity Analysis and Distribution Investment Deferral Framework maps

The Integration Capacity Analysis (ICA) and Distribution Investment Deferral Framework (DIDF) maps are designed to help contractors and developers find information on potential project sites for Distributed Energy Resources (DERs). The maps include hosting capacity, forecast data, grid needs, and other information about PG&E's electric distribution grid.

The information on these maps is illustrative and is likely to change or be modified over time. PG&E's electric distribution system is dynamic. Circuits on the distribution system change for various reasons. Examples include, but are not limited to, circuit upgrades, new loads, new DERs, new circuits, and seasonal switching. Over time, a single location may have different results due to these changes.

Many factors affect interconnection capability and costs, and the maps do not guarantee that generators can interconnect. In addition, government permitting procedures may limit the suitability of a site. These procedures are designed to minimize environmental and land use impacts and are independent of PG&E's interconnection process. For these reasons, you should contact and work with PG&E directly to obtain accurate information to evaluate the specific details of your project.


Generation customers must submit an interconnection application through the Interconnection Portal to determine requirements and costs based on the project's location, size, and application date compared with other projects in the same area.

Wholesale Distribution and Rule 21 Export customers can be evaluated by applying through "Your Projects." Customers are encouraged to use the Pre-Application process to get general engineering review of a specific site without committing to a project application or queue.

Please refer to the public generation interconnection queue status to see if capacity is already being used by queued projects.


Load customers must submit an application for service using "Your Projects."

Load customers requesting a new service, relocation, or change to an existing service can access online tools and resources.

Please refer to location services for siting new projects.

DIDF opportunities

The DIDF process leads to the DIDF Request for Offers (RFO), the DIDF Standard Offer Contract (SOC) pilot and the DIDF Partnership Pilot. Visit Wholesale Electric Power Procurement for more information.

announcement icon Alert - Data correction


PG&E identified and corrected an issue in the ICA code that incorrectly calculated minimum value. We have corrected these values on the map and the downloadable shapefile, and are in the process of correcting the tabular files. The issue affected approximately 550 line sections, less than 0.05% of the line sections analyzed in the ICA system. Please contact us at if you have any questions.

safety icon Follow Up - Data Correction


PG&E recently identified incorrect project cost data in Appendix A (Planned Investments) and Locational Net Benefits Analysis (LNBA) values in Appendix E (LNBA – Planned Investments) for six projects (Weber 1102, Ashlan 1112, Beresford 401, Shepherd 2112, Tracy 1106, and Tres Vias 900). This error has no impact to the final Candidate Deferral Opportunities. PG&E refiled Appendix A and Appendix E with the correct information on March 24th, 2023.

safety icon Follow Up - Intermittent error


We have updated the ICA map to fix the intermittent pop-up error. Please refresh your cache, and email us at if you are still experiencing the error.

announcement icon Alert - Data correction


An error related to the published project costs was found on the DIDF map and DDOR appendix, and is undergoing correction. There is no impact on the Candidate Deferral Projects. PG&E is working on correcting this, and will share more information by the end of the week.
