It covers only voltage ride-through and post-fault active power recovery, for the computational load (~70-90% of site load), mirroring ERCOT NOGRR 282 and MISO. Cooling loads are exempted.

It commits only the computational load (typically 70-90% of a site) to ride-through, excludes cooling loads, and proposes that existing facilities never have to comply. Interpretation: SLED regulators will read this as an industry negotiating position, and account teams should present it that way.","engineering":"Engineering framing: the spec follows MISO's convention and closely mirrors ERCOT's NOGRR 282, with constant power from 0.9 to 1.2 p.u. and 90% load recovery within 2 seconds after faults. It states true fault ride-through is not achievable with current UPS and PSU designs, and that compliance may need PSU firmware, MV-UPS or hardware redesign that varies by OEM. Pre-sales engineers should validate per-site, per-PSU feasibility.","delivery":"Delivery framing: the implementation plan proposes an effective date, lifetime exemption for operating or contracted facilities, and voluntary best-effort compliance for grandfathered sites.
