The Illinois Power Agency, in collaboration with ILLUME Advising (ILLUME), a national research firm selected as the Evaluator of Illinois Solar for All (ILSFA), has released the 2022-2023 Program Year Annual Evaluation Report. The ILSFA program must undergo regular evaluation to measure its impact and identify future opportunities for improvement.
In addition to reporting the overall program metrics, ILLUME evaluated energy, environmental, and social impacts and findings for projects approved in and energized by the end of the 2022-2023 program year, which ran from June 1, 2022, to May 31, 2023. Job and economic impacts for these approved and energized projects were also analyzed to determine the financial benefits passed down to program participants.
Findings from the Annual Evaluation report include:
- Projects approved for ILSFA in the 2022-2023 program year resulted in an estimated 33.1 GWh/year of solar energy produced, and projects energized helped to satisfy participant electricity demand on a day when the high temperature was approximately 100 degrees Fahrenheit, and the electric grid loads reached their annual maximum values.
- The modeled GDP impacts of 2022-2023 program year energized projects totaled over $29.5 million, of which more than $12 million came from investments in community solar projects.
- The average per-participant monthly net savings range from $47 to $95 for residential Distributed Generation participants and $72 for Community Solar participants.
- From the 2021-2022 program year to the 2022-2023 program year, the total number of approved residential projects increased by 25% from 209 to 261, representing a 13% increase in solar capacity.
The Illinois Power Agency is hosting a webinar in which ILLUME will present its findings from the 2022-2023 Program Year Evaluation Report, answer questions, and share planned data collection and plans for future evaluation reports.
