2026.08.11 | RTO Tariff Revisions & FERC’s Cost-Allocation Mandate

The six major RTOs and ISOs are facing an imminent August 17th deadline to file revised data center interconnection tariffs in compliance with FERC’s landmark June 18th cost-allocation order. This directive requires data centers to bear the full cost of grid upgrades directly tied to their own interconnection, presenting severe mathematical challenges for operators attempting to isolate direct-tie assets from broader transmission system benefits in highly integrated alternating current networks. Utility planners and regulatory analysts must analyze these RTO filings to manage rising stranded asset risks while navigating the 3-to-5-year battery permitting mismatch and SPP's out-of-market dispatch overrides that artificially mute local scarcity price signals.
