Frequently Asked Questions

What is a Group Study

A group study is a distribution analysis consisting of multiple distributed generation (DG) projects and their collective impact on the system, to understand what system modifications would be required to support these DG projects when interconnected. When done on an individual project basis, this analysis is referred to as an impact study.

I received a notification on June 12th that my project will be part of the group study. How do I know which project is being included? 

After the general notification went out, customers received a project specific, individual follow up with the work order number/application ID that was invited to be part of the Group Study.
