Central Ohio data-center power demand
The breakout emerging market — where gigawatt-scale hyperscale campuses turned Columbus's suburbs into a national power story.
Central Ohio — New Albany, Hilliard, and the broader Columbus metro — has become the emerging market everyone watches. Gigawatt-scale sites are in development and hyperscalers including AWS have committed multi-billion-dollar campuses, pulling Ohio into the same league as the established primary markets.
The speed of that ramp put AEP Ohio's load forecast under strain and triggered a regulatory fight over who pays for the grid upgrades large loads require — an early test case for the data-center cost-allocation debates now spreading nationwide.
Why it matters
As primary markets like Northern Virginia hit capacity limits, demand spills into secondary markets — and Ohio is first in line. How its regulators handle cost allocation and interconnection will set precedent for every emerging market behind it.
