These maps are designed to help contractors and developers find potential project sites. The maps show electric transmission lines, distribution lines and substations in our service areas. They also list information such as hosting capacity, grid needs, operating voltages, line capacity and substation names.
The map does not guarantee that generators can interconnect at particular times and places. Many factors affect interconnection capability and costs, for example:
You can submit an Interconnection Application to our Generation Interconnection team through email: email@example.com. We'll determine your requirements and costs based on our review of your project's location, size and application date compared with other projects in the same area.
In addition, government-permitting procedures may limit the suitability of a particular site. These procedures are designed to minimize environmental and land use impacts. They're independent of our interconnection process.

Pacific Gas and Electric Company (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 including publishing a Grid Needs Assessment (GNA) report.
The data being released is PG&E's intellectual property. By using this information parties agrees to:
While PG&E supports GNA's scope as currently defined, PG&E cannot support the inappropriate use of this data that:
PG&E's sharing of GNA or any other information is contingent on the above areas being aided or unaffected.
Following are frequently asked questions (FAQ) and answers about our PV RAM project map.
Will PG&E provide the map in a Google Earth® file format or any other downloadable format?
At this time, we do not plan to make the map available in any other downloadable format. Following are the reasons for this decision:
Will PG&E provide the information in the pop-up windows for electric distribution lines in a table format, such as Excel or comma-separated value (CSV)?
Some data is provided through links in pop-ups. We're considering providing information in a broader data portal as part of an ongoing project.
Why doesn't the map show the locations of existing distributed generators?
The California Public Utilities Commission (CPUC) doesn't require utilities to show the locations of existing distributed generators. Only the amount of the generation on a circuit is required. In addition, the distributed generators are not owned by PG&E. We don't have permission from distributed generators to show their facility locations. Therefore, the map is not configured to provide this type of information.
