The Public Utilities Commission of Ohio regulates the state's investor-owned utilities — setting the rates, terms, and service standards under which a company like AEP Ohio delivers electricity. Its cases run as docketed proceedings with filed testimony and public comment, so a PUCO docket is a durable record of what a utility proposed and what it was allowed.
PUCO is where the cost of accommodating a new large load can surface: a utility's request to build infrastructure, recover a special-contract arrangement, or shift the cost of serving a hyperscale customer onto or away from other ratepayers runs through the commission. It pairs with the Ohio Power Siting Board, which certifies where a major facility is built; the separate federal FERC holds jurisdiction over interstate wholesale power, while the PUCO's own authority is the state's retail service and rates — a division of labor the platform keeps straight when tracing who approved what.
