Tortoise Capital Advisors plans to launch the Tortoise Energy & Infrastructure Interval Fund in the second half of 2026, adding a new semi-liquid vehicle to its platform focused on a diversified mix of energy and infrastructure investments. The strategy will span both public markets and private assets, seeking to give investors broader access to opportunities across the evolving energy ecosystem. 

The fund will target assets across the energy value chain—upstream, midstream and downstream—covering exploration and development, power generation, storage, utilities and related infrastructure tied to electrification and rising power needs from digital and AI-driven growth. Overland Park, Kansas-based Tortoise, which manages approximately $8.9 billion in assets, expects to partner with a “best-in-class” private energy and infrastructure manager to oversee the private allocation, bringing deep sourcing, underwriting and operational capabilities. 

CEO and Chairman Tom Florence said the offering is designed to marry Tortoise’s long-standing expertise in public securities with the institutional capabilities of a leading private energy manager, creating a differentiated interval fund structure with a built-in liquidity buffer not typically seen in the space.  

Under the anticipated partnership, Tortoise will lead product design, portfolio oversight, distribution and public-market investments, while the private manager focuses on originating and executing private deals across the strategy’s target sectors.
