This 11% Yielder Powers AI’s Insatiable Appetite But The Leverage Makes You The Co-Pilot

Energy Infrastructure Is Having Its Moment. The Question Is Whether TYG Is The Best Way To

Every week, we’ll profile a high yield investment fund that typically offers an annualized distribution of 6-10% or more. With the S&P 500 yielding less than 2%, many investors find it difficult to achieve the portfolio income necessary to meet their needs and goals. This report is designed to help address those concerns.

Macro Context

The artificial intelligence revolution has an energy problem. Not a software problem, not a talent problem — a raw, physical, megawatt-hours-per-day problem. Morgan Stanley estimates that U.S. data center electricity demand could reach 74 gigawatts by 2028, creating a 49 GW shortfall against current capacity.^[1] The EIA projects U.S. electricity consumption will rise 1.9% in 2026 and 2% in 2027 — the fastest demand growth in decades.^[2]

Power industry capital expenditures hit $1.5 trillion in 2025. Wolfe Research forecasts natural gas generation additions for 2025–2029 approaching 70 GW, more than double projections from a year earlier.^[3] Natural gas prices have responded, with Henry Hub trading above $5/MMBtu for the first time since late 2022.

Enter Tortoise Energy Infrastructure Corp. (TYG) — a $1.4 billion closed-end fund yielding 11.69% that sits at the nexus of everything the AI buildout needs: pipelines, utilities, power generation, and the midstream plumbing that moves natural gas from basin to turbine.

Fund Background

TYG launched in February 2004 as one of the first CEFs dedicated to energy infrastructure. Managed by Tortoise Capital Advisors, the fund invests in equity securities of North American energy infrastructure companies — pipeline operators, natural gas processors, power generators, and regulated utilities.^[4] Unlike a pure MLP fund, TYG has evolved its mandate to include C-corp utilities and power companies, broadening exposure to the full energy value chain.

The fund employs structural leverage of approximately 20.8% of total assets ($280 million outstanding) at an effective all-in cost of 4.71%. TYG reports on a 1099 basis rather than issuing K-1s, removing a major administrative headache for income-focused investors.
