Implementation of Dynamic Line Ratings
Commenters in the Order No. 881 proceeding expressed a range of opinions on whether and how the Commission should require the implementation of DLRs. On one end of the spectrum, Southwest Power Pool, Inc.’s Market Monitoring Unit (SPP MMU) stated that it supported a requirement for DLR implementation on all transmission lines.[17] Similarly, Industrial Customer Organizations and the R Street Institute contended that DLRs should be required by default, with exceptions given when justified by cost-benefit analyses.[18]
