Investment Thesis

The AI power story's safest expression: every data centre signs a decades-long power contract with somebody in this book, and regulators guarantee the return on the grid spending that follows. A -7% year as yields rose is the standard utility rate-sensitivity — and the standard entry: utilities bought at rate peaks have historically compounded through the cuts that follow, with 2.6% paid along the way and demand growth running at levels the sector hasn't seen in a generation.

Who It's For

Defensive income investors who want the regulated side of the AI power boom — bond-proxy stability with a growth story attached for the first time in decades.
