Distributed Generation Guidelines for Customer-Owned Generation
This information applies to Xcel Energy service territories in Michigan only.
FERC Rules
Federal Energy Regulator Commission (FERC) provides standards for small generation (less then 20 MW) interconnection for facilities within the jurisdiction of the commission. This generally applies to transmission-level interconnection. Distribution-level interconnection is usually regulated by each state's public utilities commission.
State Rules
The Xcel Energy interconnection documents comply with the 2003 version of R 460.601-460.656. The link below is to the 2009 version with which all other Michigan utilities must comply. The 2003 version can be found below attached to the Xcel Energy only interconnection requirements document.
