Data Center Signal is tracking 3 clips about Midcontinent Independent System Operator data center developments across 3 states, including IL, IN, WI.
The rapid boom in AI data centers is causing significant strain on PJM Interconnection LLC, the largest US power grid operator, raising concerns about its potential breakup. Such a development would make Carmel, Indiana-based Midcontinent Independent System Operator (MISO) the leading electric grid operator in the nation.
Central and southern Illinois residents could face another summer of high electricity rates due to capacity auction results and rising demand, partly from data centers. Utilities Ameren Illinois and ComEd are navigating grid stability challenges, and state agencies are developing long-term energy plans to address looming shortfalls. Critics are concerned about the slow pace of these planning efforts.
A coalition of utilities, including Xcel Energy and American Transmission Company, has asked the Federal Energy Regulatory Commission (FERC) to pause competitive bidding for transmission projects, arguing that delays hinder the infrastructure needed for AI and data centers. Ratepayer advocacy groups, such as the Wisconsin Citizens Utility Board, oppose this, warning it could lead to higher electricity bills for consumers.
