anti-islanding performance, voltage/
frequency protection, and the potential for
reverse power flow.1 Stage Pre-Application
Documentation
The interconnection process begins with the
submission technical and administrative
documentation via TEPCO’s online
application portal through licensed
electrical contractor authorized to
coordinate distributed energy connections.g.3. National Survey Report Power Applications Japan 2019. This
