View the solar photovoltaic and renewable auction mechanism (PV RAM) project map

The map is designed to help contractors and developers find potential project sites. The map shows electric transmission lines, distribution lines and substations in our service areas. It also lists information such as 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:


  • Distributed generation system size
  • Distributed generation system type, such as inverter or machine-based
  • Circuit load and substation and capability
  • Operating voltage

You can submit an Interconnection Application to our Generation Interconnection team through email: 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.

  • The map shows selected electric transmission lines, distribution lines and substations in our service area.
  • Contractors and developers use the map to find potential project sites.
  • Our electric system is dynamic. Circuit configurations on the distribution system change for various reasons. Examples include new loads, undergrounding projects, seasonal switching patterns, new circuits, voltage and reliability.
  • We update the map monthly. Over time, a location may produce different circuit results.
  • You must log in to access the map.

View frequently asked questions

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:


  • The need to keep files that represent the electric system out of the public domain
  • The dynamic nature of our electric system, and the prospect of different users with varying files and system configurations
  • The method used to display the data and its associated volume


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)?

We’re considering providing the distribution circuit data in a tabular format.


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.
