What HASI does
HASI (HA Sustainable Infrastructure Capital, Inc.), a publicly traded firm on the NYSE under ticker HASI and headquartered in Annapolis, Maryland, is a specialty sustainable infrastructure investment manager focused exclusively on climate solutions. The company invests across three markets: Behind-the-Meter (distributed solar, storage, and energy efficiency), Grid-Connected (utility-scale solar, onshore wind, and battery storage), and Fuels, Transport & Nature (renewable natural gas, clean transportation, and ecological restoration). HASI provides flexible capital structures including structured equity, senior debt, mezzanine financing, tax equity, and a specialized land financing product with nearly $2 billion in closed transactions. The firm's underwriting platform is anchored by its proprietary CarbonCount® metric, which standardizes environmental impact measurement (metric tons of CO2e avoided per $1,000 invested) and underpins performance-linked pricing on its credit facilities.
HASI generates revenue primarily through investment income (interest, dividends, and fees from its portfolio of sustainable infrastructure assets), supplemented by asset management and advisory fees from co-investment vehicles, including CarbonCount Holdings 1 with KKR. The firm sources transactions through enterprise, relationship-driven origination with developers, owners, and operators of clean energy projects, including programmatic partnerships with companies such as AES, Sunrun, Ørsted, ENGIE, Clearway, Pattern Energy, Lightsource bp, Ameresco, and Morgan Stanley. As of Q1 2026, HASI managed over $16 billion in assets across 1,300+ cumulative investments, sourced an annualized adjusted recurring net investment income of approximately $400 million, and held investment-grade credit ratings (Baa3/BBB-/BBB-) from Moody's, Fitch, and S&P.
The business model is asset-yield-driven: HASI raises long-dated capital through a green bond framework (S&P "Dark Green" assessment), credit facilities, and co-invest vehicles, then deploys it at new-asset yields above 10.5% across contractually backed clean energy cash flows with investment-grade counterparties. The firm completed a record $4.3 billion in new transactions in 2025 (87% YoY growth) and is expanding into new verticals such as advanced biofuels, sustainable aviation fuel, and bio-LNG through the Neogenyx Fuels joint venture with Ameresco. The company revoked its REIT election effective January 1, 2024, becoming a taxable C-Corporation to enable larger structured equity and joint venture commitments.

HASI competitors and assessment
Company assessmentDirect peers
- Generate Capital: Privately held sustainable infrastructure investment platform financing distributed energy, storage, transportation, and circular economy projects. Closest private-market peer to HASI in terms of investing across behind-the-meter, grid-connected, and emerging clean-infrastructure verticals.
- Brookfield Renewable Partners: One of the world's largest publicly traded renewable energy and storage platforms, owning and operating utility-scale hydro, wind, solar, and storage assets. Directly comparable to HASI in its role as a capital provider and asset owner in clean-energy infrastructure across North America.
- Clearway Energy: Publicly traded renewable energy company operating utility-scale wind, solar, and energy storage assets across the U.S. Direct HASI counterparty and competitor for clean-energy infrastructure capital, with comparable portfolio scale and contracted revenue profile.
- NextEra Energy Partners: Yieldco affiliated with NextEra Energy that acquires and manages contracted renewable energy projects, primarily wind and solar, with long-term PPAs. Highly comparable business model of contracted clean-energy cash flows, similar to HASI's grid-connected portfolio.
- Atlantica Sustainable Infrastructure: Publicly traded sustainable infrastructure company that owns and manages a diversified portfolio of renewable energy, efficient natural gas, and water assets in North America, South America, and EMEA. Closely mirrors HASI's model of providing long-term capital to contracted sustainable infrastructure.
Broad incumbents
- BlackRock Global Infrastructure Partners: Mega-fund infrastructure platform (formerly Global Infrastructure Partners) with significant renewable energy exposure. Competes with HASI for institutional capital flows into clean-energy assets but operates at significantly larger fund size and broader infrastructure mandate.
- Macquarie Asset Management (Green Investment Group): Global infrastructure and renewables asset manager with one of the longest-running dedicated green investment franchises. Comparable to HASI in originating and financing renewable energy projects across solar, wind, and emerging transition assets.
- Stonepeak Infrastructure Partners: Large private infrastructure investor with significant renewable energy and energy transition focus. Comparable to HASI's infrastructure finance model but with broader infrastructure mandates including transport, digital, and conventional energy assets.
- KKR Global Infrastructure: Major global infrastructure investor with renewable energy as a core strategy, and an actual HASI co-investment partner (CarbonCount Holdings 1). Comparable in its deployment of institutional capital into clean-energy projects but operating at vastly larger AUM scale across multiple asset classes.
Emerging players
- I Squared Capital: Independent global infrastructure investor with active renewable energy and energy transition strategies. Comparable to HASI in targeting mid-to-large scale clean-energy equity and debt investments, particularly in distributed and utility-scale renewables.
