These projects have involved low-income housing tax credits, new markets tax credits, and historic tax credits.

He has extensive experience in solar, wind, and battery storage projects. Louis also has experience with electric vehicles, advanced manufacturing facilities, and the related incentives, programs, and tax credits.
