Traditional Community Solar (Group A and Group B) – Next Steps

As detailed above, the available 2026-27 block capacity allocation was not exceeded for either Traditional Community Solar Group A or B on the first day of the Program Year. Per Section 1.E of the Program Guidebook, if project applications batched on the “first day” do not exceed category capacity, then all applicant projects otherwise qualifying shall be deemed acceptable and may qualify for a REC Delivery Contract. Should category capacity fill later in the Program year, then from that point forward, only projects meeting this scoring threshold of 5 points may be considered for an eligible spot on the waitlist for the Traditional Community Solar category.

Community-Driven Community Solar (Group A and Group B) – Next Steps

As noted in Section 1.E. of the Program Guidebook, each Program Year there will be a 90-day application window for Community-Driven Community Solar projects to be submitted prior to any project selection. Upon closing of the 90-day application window, projects will be reviewed and scored based on the scoring criteria as outlined in Appendix F of the Program Guidebook, with projects selected from the application pool in the order of highest to lowest score until the available block capacity is fully allocated. A minimum score of 6 points must be achieved to be eligible for a REC contract in the CDCS category. After project selection for any given Program Year, projects that have a minimum score of 10 points will be placed on a waitlist for when capacity becomes available, which may be the following Program Year.

Thank you!
