The threshold: MISO wants to define large loads as projects with >50 MW of demand, and carve out a category for “computational loads” with >25 MW of demand from IT equipment.
The requirements include: 1) Providing real-time and day-ahead load forecasts and 2) demonstrating that these facilities can ride through an unexpected drop in grid voltage.
Plus: The grid operator has proposed a fast-track large-load interconnection process for projects >250 MW (with contracted generation). By studying the load and generation in parallel, MISO could offer approval within 120 days.
