FERC initiated a rulemaking on dynamic transmission line ratings, Managing Transmission Line Ratings, Docket No. RM20-16-000. The Notice of Proposed Rulemaking proposes to reform the pro forma Open Access Transmission Tariff and the Commission’s regulations to improve the accuracy and transparency of transmission line ratings. Specifically, the proposal would require: (1) transmission providers to implement ambient-adjusted ratings on their transmission lines; (2) Regional Transmission Organizations and Independent System Operators (RTOs/ISOs) to establish and implement the systems and procedures necessary to allow transmission owners to electronically update transmission line ratings at least hourly; and (3) transmission owners to share transmission line ratings and transmission line rating methodologies with their respective transmission providers and, in RTOs/ISOs, relevant market monitor(s). Comments are due on or about mid-January 2021.
