HA Sustainable Infrastructure Capital (HASI)

The company, formerly widely known as Hannon Armstrong, works with project developers, asset owners, and corporate or public-sector customers that need capital for infrastructure tied to decarbonisation. Its investments can include interests in renewable energy projects, distributed energy systems, efficiency upgrades, storage, and related infrastructure. Rather than focusing on a single technology, HA Sustainable Infrastructure Capital aims to build a diversified portfolio across the energy transition, balancing yield, risk, and long-term growth potential.

Revenue and earnings are driven by net investment income, equity method income from project interests, gains on asset sales, and recurring fees from asset management activities. The model depends on disciplined underwriting, access to capital markets, and the ability to structure investments that match the cash-flow profile of sustainable infrastructure assets. What distinguishes the company is its role as a specialist capital provider in a sector where large amounts of private investment are needed. It connects institutional capital with real assets that are designed to reduce emissions, improve energy productivity, or modernise critical infrastructure.
