HASI is a public investment vehicle focused on renewable energy and storage infrastructure, with $16B in managed assets across solar, wind, RNG, and distributed energy projects.

The tech stack reflects traditional institutional finance: SQL Server, Power BI, Tableau, and Intacct, with documented pain around transaction closing workflows and cross-portfolio integration.
