HA Sustainable Infrastructure Capital, Inc. (HASI) and the American investment firm KKR have announced a new joint commitment of $1 billion to CarbonCount Holdings 1 LLC (CCH1), their co-investment vehicle dedicated to long-term financing of sustainable infrastructure projects in the United States. Each entity will invest $500 million, reinforcing their joint strategy for capital deployment in the energy sector.
CCH1 was initially launched in May 2024 with a $2 billion contribution shared equally between the two partners. This new contribution raises the combined commitments to $3 billion. Including the financial leverage already in place, the vehicle’s total investment capacity is expected to reach approximately $5 billion.
Extended investment period to support growth
The investment period has been extended to the end of 2027 or until all funds are deployed, whichever comes first. The extension supports the rapid growth of the portfolio, which has reached nearly $3 billion in commitments across various asset classes in just 18 months.
In June 2025, CCH1 had already strengthened its financial structure by raising $592 million through the issuance of 20-year senior unsecured fixed-rate notes. This transaction expanded the fund’s operational capacity while maintaining a long-term structure attractive to institutional investors.
Targeted diversification of energy assets
Investments span six asset classes, including renewable energy, storage systems, transmission networks, and energy efficiency projects. The portfolio is structured to reflect growing long-term demand for energy solutions in the North American market.
HASI’s Chief Revenue and Strategy Officer stated that the platform enables “efficient capital deployment into projects addressing the country’s rising power demand.” KKR highlighted the strength of the partnership, describing it as “evidence of the robustness of current market opportunities.”
A funding model aligned with sector needs
The partnership aligns with a broader strategy to mobilise patient and flexible capital for capital-intensive projects. CCH1’s long-term commitments respond to increasing demand for structured financing, especially for projects with ten-year or longer timelines.
The continued investments through CCH1 come at a time of heightened infrastructure needs, driven by grid modernisation targets and the growth of new models for energy production and distribution across the United States.
