Urgent Alert

Distributed Resource Planning (DRP) data & maps

Find details on potential project sites for Distributed Energy Resources (DERs)

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.

PG&E has transitioned the PVRAM map data to the ICA and DIDF maps. All data is available on these maps. 

Access ICA map

The ICA map is designed to help contractors and developers find potential projects sites for DERs.

Access DIDF (GNA/DDOR) map

The DIDF (GNA/DDOR) map shows assumptions and results of the distribution planning process that yield grid needs related to distribution grid services.

Interconnection Projects with PG&E

The data and maps on the DRP Data Access Portal do not provide any guarantees. All interconnections are subject to engineering review. Many factors affect interconnection capability and costs, and the maps 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.


Generation customers

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

Submit an application 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.

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.

The DIDF process leads to the DIDF Request for Offers (RFO) and the DIDF Partnership Pilot.

PG&E has a strong interest in enabling technologies, models, policies, and ways of thinking that advance public safety, system reliability, energy affordability, and clean energy adoption within its service territory. As such, PG&E supports the Distribution Resources Plan's objectives.


The data being released is PG&E intellectual property 

By using this information, parties agree to:

  1. Recognize this information and all derivatives as the property of PG&E;
  2. Not utilize this information beyond its intended use.


While the ICA and DIDF maps include the best information currently available, PG&E makes no representation as to the accuracy or quality of the data provided, its fitness for the purpose intended, or its usability by the recipient; PG&E cannot be held liable for inaccuracies or the impact of decisions made on this information.


PG&E does not support the inappropriate use of this data that:

  1. Puts the physical or cyber-security of the electric grid or gas pipelines at risk;
  2. Violates customer privacy;
  3. Compromises sensitive market data; or
  4. Voids company intellectual property, patents, or trade secrets.


PG&E's sharing of the information on this map is contingent on the above areas being aided or unaffected. PG&E notes that, although as of December 31, 2018, the maps and data are available for on-line registration and access by third-parties without further restriction, PG&E has requested the Commission to authorize it to restrict third-party access to Critical Energy Infrastructure Information ("CEII") on and underlying the map, and reserves the right to implement and enforce such restrictions upon approval by the Commission in order to protect its electric distribution system from physical attack and cybersecurity threats.
