2026.08.18 | FERC’s Section 206 Deadline & The RTO Large Load Interconnection Battle

Yesterday's August 17th deadline for the six major RTOs and ISOs to respond to FERC’s Section 206 show cause orders marks a critical regulatory inflection point for large load interconnection tariffs. These landmark filings address four core operational categories—flexible large loads, collocation, behind-the-meter generation, and electrically approximate facilities—while state-level actions concurrently advance Oncor’s 765kV transmission line docket in Texas and Southern California Edison's hydroelectric asset divestiture. Utility executives and project developers must closely analyze these highly fragmented regional responses to manage predictable discounted cash flow models, mitigate cost-shifting risks to legacy ratepayers, and navigate shifting state-level capex recovery baselines. This final weekly briefing of Current Events: The Electric Utility Today marks the official conclusion of this broadcast series, and we extend our deepest gratitude to the transmission engineers, financial analysts, system operators, and utility executives whose daily work remains central to the operational stability and financial viability of the grid. As we sign off, we leave our community of power professionals with one final planning question: are statutory frameworks designed for the 20th century structurally capable of scaling at the speed required by the technological load growth of the 21st?
