FERC Initiates Rulemaking on Managing Transmission Line Ratings

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.

For those interested, another great post on Energy Central on this topic was recently published: https://energycentral.com/c/tr/it%E2%80%99s-time-use-accurate-line-ratings%E2%80%A6

While forcing the reliability coordinators and transmission operators to use dynamic line ratings is not necessarily a bad thing, it is not the “silver bullet” for all transmission system constraints. This will allow thermal ratings to be moved up on the transmission lines. It does nothing to address potential thermal limitations within the substation equipment or protection systems. Also, if a transmission system has a stability limit or a voltage limit causing a restriction, upping the thermal capability of the transmission lines doesn't buy you anything. People have to understand dynamic line ratings are a good thing, but they do not cure all the evils that are out there.

There are so few real silver bullets out there-- given that, do you have additional 'prescriptions' you'd add that could go well with dynamic linie ratings, John?
