 Note: There will be a transition period through the end of 2024. Until then, availability of the old maps is as follows:

• The ICA map, API and downloadable data will be maintained and updated to support users
• The DIDF map, API and downloadable data will be maintained, but not updated

Grid Resource Integration Portal

The Grid Resource Integration Portal is designed to help engineers and developers find information on potential project sites for Distributed Energy Resources (DERs). The map includes 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.

Access the Grid Resource Integration Portal and legacy maps

The new Grid Resource Integration Portal is a directional tool designed to support interconnection, energization, and planning.

Interconnection Projects with PG&E

The data on the Grid Resource Integration Portal do not provide any guarantees. All interconnections are subject to engineering review. Many factors affect interconnection capability and costs, and the data do not guarantee that generators or load can interconnect at a specific site or in a specific time frame.

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.
