MISO (Midcontinent Independent System Operator) proposed rules for loads above 50 megawatts, including computational loads with 25 megawatts of IT demand.

The Midcontinent Independent System Operator proposed reliability requirements for large electricity loads. MISO defines a large load as one exceeding 50 megawatts.

The proposal separately defines a computational load as a large load containing at least 25 megawatts of demand from information-technology equipment. This distinguishes the IT component of a data center from the site’s overall electricity demand, which can also include cooling and other facility systems.

The separate classifications allow MISO to direct particular requirements toward data centers and other computational facilities. The supplied source description did not specify the complete interconnection process, compliance deadlines or penalties under the proposal.
