Wisconsin Interconnection Standards
|Date Last Updated||11/16/2012|
|Policy Type||Interconnection Standard|
|Policy Administrator/Contact Office||The Public Service Commission of Wisconsin (PSC)|
|Policy Initiation Date||2/1/2004|
|Policy Summary||The PSC has adopted interconnection standards for distributed generation (DG) including CHP systems <15 MW in capacity. The rules categorize DG including CHP systems by capacity and provide for several levels of interconnection review, as follows: |
Minimum liability insurance of at least $300,000 per occurrence is required for systems <20 kW (Category 1) with higher amounts for larger systems based on the category of review under which they fall. However, the law also permits applicants to prove financial responsibility using a negotiated agreement with the utility in lieu of the insurance requirements. Additionally, Category 2-4 facilities must name the utility as an additional insured party in the insurance policy.
Application and study fees vary by category, but systems <20 kW are not required to pay any fees. Facility owners are permitted to file an appeal with the PSC if they believe they are being held to unreasonable requirements, but the rules provide do not provide any guidance on how such appeals will be addressed.
|CHP Eligibility Requirements||Both fossil-fueled and renewably-fueled CHP systems are eligible for standardized interconnection.|
|Eligible Project Size (MW)||Standardized interconnection applies to systems <15 MW.|
