FERC decided it’s practical for MISO to have an almost three-year extension of the commission’s directive to implement ambient adjusted transmission line ratings.

FERC accepted a 17-month delay to ISO-NE and transmission owners’ implementation of Order 881 and Order 881-A compliance, pushing back the rollout of ambient-adjusted line ratings in the region.

The SPP Markets and Operations Policy Committee has approved tariff revisions that would implement dispatchable transactions in the real-time energy market.

The commission received dozens of comments on its advanced notice of proposed rulemaking that would require broad use of dynamic line ratings across the U.S. transmission grid.

National Grid introduced a pair of asset condition projects estimated to cost about $538 million to the ISO-NE Planning Advisory Committee.
