The Illinois Power Agency (the Agency) seeks public comment on a proposed modification to the new Distributed Generation (DG) Disclosure Forms.
The new Distributed Generation (“DG”) Disclosure Forms that were put out for public comment in December 2022 (for implementation starting June 1, 2023) included a new section titled “Project Efficiency.” The intent of the section was to provide information to customers on if their project was designed or sited in a sub-optimal way. For example, if a solar project is shaded or is sited on a northern facing roof, it is important that the customer understand the limitations of the project design and/or siting. The IPA proposed this new disclosure because it is aware that projects have been submitted in both the Illinois Shines and Illinois Solar for All programs that have relatively low performance because of siting or design issues.
In the public comments, questions were raised about exactly what number would be disclosed and how that number would be calculated.
Based on that feedback, the Agency is considering modifying this portion of the disclosure form to be framed as “Project Performance” – that is, eliminating the use of the term “efficiency” – and using the Total Solar Resource Fraction (“TSRF”) as the actual number that is disclosed.
The Request for Public Comment includes additional information regarding the proposed modification and a mock-up of how the disclosure form’s new “Project Performance” section would appear using the TSRF approach.
Comments in response to this request are due on March 10, 2023. Comments should be submitted to ipa.contactus@illinois.gov with the subject line “[Responding Entity Name] – Response to New DG Disclosure Forms – Project Performance (“Efficiency”) Disclosure. Comments will be posted online.
