DER Application

Instructions
This application must be completed and submitted with fees established in Table III of the Interconnection Requirements of Wisconsin Electric Cooperatives (IRWEC), which are also show below. Personal information collected will be used for administrative purposes only.

This application is for interconnection to the electric distribution system of distributed energy resource (DER) systems sized up to 15 megawatts (MW) alternating current (AC) and associated equipment in compliance with the IRWEC.

If a DER Facility has an interconnection agreement but has simply changed ownership, do not fill out this form. Fill out "Change of Ownership Form for DER Systems".

An applicant seeking to interconnect a distributed energy resource facility to the distribution system of an electric cooperative shall maintain liability insurance equal to or greater than the amounts stipulated in the Table below, per occurrence. 

Applicant Contact Information














Location of the DER System










Does this application relate a change or modification of an existing system?
If there is already generation at the point of interconnection, this is a modification, and the total export capacity kW in alternating current at this location (existing plus addition) shall be used within this application.







Electricity Use, Production and Purchases



Project Design and Engineering





Installing Contractor Information (if known)








If protective equipment is separate from the inverter, provide a protection and control diagram along with data sheets on all related equipment in accordance with IRWEC. If equipment is known, attach manufacturer specification data sheets.
