Portal Updates

Portal Development Roadmap

The Portal Development Roadmap is designed to preview upcoming, planned development for the Illinois Shines portal. Updates on the following planned activities will be provided in weekly Program announcements, and detailed below in the Portal Updates Blog in conjunction with software releases.

 

Roadmap Update: December 19, 2026
QUARTER 4 2025 (October, November, December) 

Subscriber Management Foundations 
Foundational development for Community Solar Subscriber Management capability. When the full feature is complete, Approved Vendors (“AVs”) and Designees will be able to view, create, edit, and terminate subscription records within the Portal.  

Improved AV and Designee Company and User Structure 
Continued improvements to AV and Designee management. The Portal now: 

  • Allows companies to have multiple users per AV and Designee ID 
  • Allows users to manage Disclosure Forms for multiple Designee IDs 
  • Collects associated Designee ID on Disclosure Forms via portal, CSV, and API 
QUARTER 1 2026 (January, February, March) 

Subscriber Management  
Final development for the Subscriber Management Feature and improvements to usability. Scope to be informed by feedback from AVs and Designees. 

Batch Fee Report 
Show batch fee calculations in real-time when AVs generate a batch to increase application fee transparency. AVs will also be able to download a report with itemized application calculations and fees for selected batches. 

QUARTER 2 2026 (April, May, June) 

Historical CS Subscriptions 
Allow AVs and Designees to add inactive community solar subscriptions to the Portal so that full historical data can be used to calculate daily averages and complete annual reporting. 

Address Validation 
Use of address validation tool to standardize installation addresses, to identify expansions, co-locations, and duplicate applications before contracting. 

Program Year 2026-27 Setup + New Long Term Plan Changes 
Changes to the Portal to support the new 2026-27 Program Year and 2026 Long-Term Plan updates. 

Community Solar Subscriber Management Portal Feature

The Program Administrator continues development of the Community Solar Subscription Management Feature for the Program Portal, which is slated for a March 2026 launch. This new feature will replace the current manual workbook process in SharePoint and will allow for improved subscriber data quality and the centralization of access. The new feature will give Approved Vendors (“AVs”) and Designees the ability to view and manage subscriptions, view unsubscribed Disclosure Forms, and import and export subscription data. Additionally, AVs will have the ability to manage project permissions and assign Designees to view/manage community solar projects. Click on each of the following sections for details on the development timelines: 

The Program Administrator invited AVs and Designees, who participated in the 2025 AV/Designee Subscriber Management Working Group, to participate in a live demo and testing session, where AVs and Designees had the opportunity to provide feedback on the new feature.

The Program Administrator will review the feedback from the AV Testing Session of the core functionality and consider potential enhancements to the Portal feature before official launch.

Mid-February: Disclosure Form Transfer Process

The Illinois Shines Program Administrator has developed the Disclosure Form Transfer process, which allows Disclosure Forms to be transferred from one entity to another in circumstances where written requests are provided to the Program Administrator from all parties involved. This will provide flexibility to Approved Vendors (“AVs”) and Designees should they need to manage Disclosure Forms that were not generated directly by that specific AV or Designee.

Based on the permissions settings in the new Subscription Management Portal Feature, AVs or Designees who did not originally generate a Disclosure Form will not be able to subscribe that Disclosure Form to a Community Solar project. The Disclosure Form Transfer Process will support these circumstances where there is a mismatch between the entity who generated the Disclosure Form and entity who is managing the Disclosure Forms and subscriptions for the project. The Program Administrator has reached out to AVs where disclosure form transfers may be necessary, asking AVs to submit requests if necessary. The full process is outlined in the Subscriber Management Training Guide.

Mid-February: Data Import

To support the launch of the Community Solar Subscription Management Feature, the Program Administrator will import all current subscriber data into the Portal in late February/early March, including the most recent subscriber data from the December Semi-Annual Verifications and the December–February Part II Quarterly Period. Prior to final subscriber data import, the Program Administrator will perform a series of data validation checks on all subscriber records. Subscriber records with any data validation errors will not be imported into the Portal. The Program Administrator will identify records omitted from the final data import due to data validation errors and share those records with Approved Vendors (“AVs”). AVs will be responsible for correcting the subscriber data errors that prevented validation and importing the updated data into the Portal once the Community Solar Subscription Management Feature is live. AVs must ensure the subscriber data in the Portal is accurate and up to date. Any records that are not imported into the Portal will not be considered for subscriber verification purposes or Annual Report daily average calculations.

Please see Appendix A of the Subscriber Management Training Guide for a list of data validations.

The Program Administrator will reach out to AVs once the final subscriber data import has been completed and outline any outstanding action items and next steps.

Late-February: Final Subscriber Data Import

The Program Administrator will import current subscriber data into the Portal that passes all required data validation checks. Any subscription rows that do not pass required data validation checks will not be imported. The Program Administrator will communicate to AVs and Designees that have impacted records to explain the data issues and how the AV can resolve the issues by updating the subscriber data and importing the data after official feature launch.

Late-February: Subscriber Management Live Webinar

The Program will host a live webinar on February 26, 2026, from 12:00 – 1:15 p.m. CPT. The webinar will provide a live demo, recorded reference resource, and detail the feature’s development, benefits, and upcoming changes to subscriber data management processes. Please register with this link.

Feature goes live in Portal. SharePoint-based process is retired.

To support the transition and the full launch of the Feature, the Program Administrator will be requiring AVs to complete several action items prior to and after launch. Each action item is listed below with a short description of the request and expected timeline. The Program Administrator will reach out to all AVs in the coming weeks with any additional updates and requests to complete these outstanding action items. 

Reviewing and confirming Designees by project: The week of February 2, 2026, the Program Administrator reached out to AVs to confirm current Designees by project by February 11, 2026. Generally, Disclosure Forms and their associated subscriptions will only be able to be managed by the “owner” of the form, which will default to the AV and/or Designee named on the form when it was initially created. The Program Administrator will be able to transfer Disclosure Forms to a new “owner” and will identify records where the current Designee does not match the Designee on the Disclosure Forms. For these mismatched records, AVs will need to consider requesting a Disclosure Forms transfer to make records editable based on the confirmed Designee associations.

Reviewing and curing data validation errors post launch: The Program Administrator will import subscriber data, which must meet required data validations, into the Portal prior to launch. Data records that fail any data validations will not be imported by the Program Administrator. These data validation errors have been identified in subscriber workbooks for remediation. The Program Administrator will identify any remaining records with data validation errors which will be omitted from the final data import. AVs will need to cure data validation issues and import the omitted subscriptions into the Portal after March 2026, once the feature is fully functional. 

Setting up project delegation: After feature launch, AVs will be responsible for delegating Designees to manage Community Solar projects in the Portal. Delegating a Designee to manage a project will allow that Designee to view all subscription records for a project. However, personally identifiable information will be redacted from records where a Designee is not the “owner”. 

Retiring SharePoint-based process: AVs will need to review the accuracy of subscription records and delegate Designees to all Part II Verified projects in the Portal after March 2026, once the feature is fully functional.
