Overview
- FERC used Section 206 show‑cause orders to require the six largest RTO/ISOs to defend or change their interconnection rules and gave each region about 60 days to respond.
- The commission said regions must address cost allocation and called for cost‑recovery or upfront funding agreements so very large loads do not shift upgrade costs onto other wholesale and retail customers.
- FERC pressed faster, clearer study tracks and asked operators to consider alternative transmission technologies and load flexibility as ways to shorten long interconnection queues.
- Industry groups, state regulators, and environmental advocates praised the focus on transparency and reliability while noting key details on who pays and which technologies will be required remain unresolved.
- The orders set a regional template that will affect future high‑growth users of power, and parallel state actions such as new Texas batch‑study rules mean implementation will vary by region and could change local rates and siting decisions.
