COMMENTS OF THE NEW ENGLAND STATES COMMITTEE ON ELECTRICITY

Pursuant to the Advance Notice of Proposed Rulemaking issued by the Federal Energy Regulatory Commission (“Commission” or “FERC”) on June 27, 2024,[1] the New England States Committee on Electricity (“NESCOE”) files comments on the Commission’s consideration of the need to establish requirements for transmission providers to use dynamic line ratings (“DLRs”) to improve the accuracy of transmission line ratings as well as potential reforms to ensure transparency in the development and implementation of DLRs.[2]

I. DESCRIPTION OF COMMENTER

NESCOE is the Regional State Committee (“RSC”) for New England.  It is governed by a board of managers appointed by the Governors of Connecticut, Maine, Massachusetts, New Hampshire, Rhode Island, and Vermont and is funded through a regional tariff that ISO New England Inc. (“ISO-NE”) administers.[3]  NESCOE’s mission is to represent the interests of the citizens of the New England region by advancing policies that will provide electricity at the lowest possible price over the long term, consistent with maintaining reliable service and environmental quality.[4]  These comments represent the collective view of the six New England States.

II. COMMENTS

NESCOE appreciates the Commission’s efforts to improve the accuracy of transmission line ratings and ensure that DLRs are developed and implemented in a transparent manner.  NESCOE strongly supports the Commission’s ANOPR.[5]

Alternative transmission technologies, such as DLRs, can provide substantial benefits to the electric grid when incorporated with existing and new transmission infrastructure.[6]  As the Commission has acknowledged, when added to existing infrastructure, alternative transmission technologies have the potential to “optimize the performance of such infrastructure, mitigating or deferring the need for development of new regional transmission facilities.”[7]  Certain alternative transmission technologies, including DLRs, can also enhance reliability benefits. [8]  NESCOE has long supported the efficient use of existing transmission facilities and the construction of new facilities, where necessary and appropriate, to ensure the transmission grid’s reliability, efficiency, and ability to integrate clean energy resources, consistent with certain States’ legal requirements and other mandates.[9]  Similarly, NESCOE supports requiring transmission providers to prioritize consideration of alternative transmission technologies when evaluating potential transmission solutions.[10]

The ANOPR builds on Order No. 2023[11] and Order No. 1920’s mandates that transmission providers evaluate alternative transmission technologies in interconnection studies[12] and transmission planning.[13]  NESCOE commends the Commission for considering how to implement DLRs in a transparent manner, and, thereby, improve the accuracy of transmission line ratings.  NESCOE is confident that efforts to adopt accurate transmission line ratings will lead to just and reasonable wholesale rates and, ultimately, consumer rates. Accordingly, NESCOE strongly encourages the Commission to advance the ANOPR to a proposed rule informed by the comments received on the ANOPR in order to encourage the continued deployment of DLRs.

III. CONCLUSION

NESCOE thanks the Commission for its consideration of these Comments.

 

Respectfully Submitted,
