CarbonCount Holdings 1 LLC Expands Investments in Clean Energy Projects
CarbonCount Holdings 1 LLC (CCH1), a strategic partnership between KKR and HA Sustainable Infrastructure Capital (HASI), has announced its investments in clean energy projects in the U.S. The joint initiative, launched in 2025, has been focusing on behind-the-meter, grid-connected, renewable natural gas, and transport projects.
The partnership between KKR and HASI was established with the objective of accelerating the build-out of sustainable infrastructure in the U.S. In 2024, the two companies launched CCH1 with $1 billion commitments from each investor. The strategic partnership was officially announced in July 2025, with the issuance of $592 million of 20-year fixed rate senior unsecured notes.
According to public information, CarbonCount Holdings 1 LLC was established as a result of this joint initiative between KKR and HASI. HASI's August 2025 quarterly filings and earnings releases mention their indirect subsidiary, confirming its activity by mid-2025. No earlier references to CarbonCount Holdings 1 LLC appear in the results, suggesting the launch occurred most likely during the first half or mid-2025.
CCH1's investments are consistent with HASI's existing investment strategy. This transaction further demonstrates HASI's ability to access low-cost capital due to the low-risk nature of their underlying assets. The investment capacity of CarbonCount has been increased to $2.6 billion following the new transaction.
Marc Pangburn, HASI's Chief Revenue and Strategy Officer, stated that the expanded investment capacity enables increased investment activity and capital efficiency. The investment period for CarbonCount's platform has been extended from 18 months to continue through November 2026.
CCH1 looks forward to further strengthening their strategic partnership with HASI. The expansion of CCH1's investment capacity is a significant step towards meeting the objective of supporting energy availability, affordability, and reliability in the U.S.
