The Midcontinent Independent System Operator - the second largest US grid operator after PJM Interconnection - on Friday proposed a set of requirements large loads must meet before they can connect to the grid, including ramping and ride-through specifications.
The “interconnection reliability requirements” framework aims to improve MISO’s visibility into large load “characteristics and behavior, support reliable planning and operational decision-making, and establish scalable and technically justified expectations proportional to demonstrated reliability risk,” the grid operator said in its filing with the Federal Energy Regulatory Commission.
The proposal is a part of MISO’s response to FERC’s mid-June “show cause” orders requiring major grid operators to set rules that meet certain criteria for adding data centers and other large loads to the grid. MISO said it plans to make additional proposals by a Nov. 16 deadline.
MISO’s proposal follows similar actions at the Electric Reliability Council of Texas and&nb
