NYISO requested a three-year extension to comply with FERC Order 881, saying it needs more time to implement software and hardware updates needed to support ambient-adjusted ratings on transmission lines.

FERC found SPP mostly in compliance with the directives of Order 881.

NYISO stakeholders gave final approval to rules for "internal controllable lines" and revisions to day-ahead market congestion settlement procedures.

NYISO members approved new rules for ambient line ratings and HVDC lines.

Grid-enhancing technologies have been piloted in many places, but with recent FERC orders and federal funding, they are poised to become much more common.

SPP’s Board of Directors and its state regulators endorsed congestion-hedging improvements that have been years in the making, accepting staff’s recommendation to approve a package of eight proposals.

FERC partly approved Order 881 compliance filings from several transmission providers, asking for more information on timelines for calculating or submitting ambient-adjusted line ratings.

FERC issued orders directing transmission providers to clarify their timelines for calculating and submitting ambient-adjusted line ratings under Order 881.

FERC approved the compliance filings of six transmission providers, including those of NYISO and CAISO, with Order 88.
