Retroactive C-PACE reimburses eligible costs incurred within a defined lookback window. For a developer who funded construction with equity and wants that equity back to redeploy, this is frequently the highest-value application of the entire mechanism — capital returned without a sale, without refinancing the senior loan, and without dilution. It is also the one developers most systematically overlook, because the window closes on its own. Run as a portfolio sweep rather than project by project, filtering on mechanical and envelope scope rather than on whether the project felt like an energy project. Includes the qualifying screen, the documentation list, and what retroactive funding does not change.
