Southwest Power Pool

Two show cause revision requests landed this week, the large-load thread runs through both, and five comment windows closed in a single day. Here is the week, in order of what you can still do about it.

The through line: show cause, twice

SPP posted two new revision requests carrying "Show Cause Order" in the title this week. Show Cause Order - Transmission Service to Large Load is open for comment through September 1, and it is the one to read first: the large-load question has been the running story in this footprint all summer, and this docket puts it squarely into the tariff process. Its sibling, Show Cause Order Non-Transmission Facilities, arrived on the tracker this week with its comment window already shut, August 7. If you meant to weigh in on that one, the window is already history, and the tracker below keeps it in view as it moves.

Also new and worth a look: the Storage Reliability and Flexibility Initiative and BP 7700 RFP Criteria Points Weighting, both taking comments through August 24.

Closing this week

Three rule changes still have their windows open, briefly:

Tomorrow, August 13: Business Practice 8200 Effective Load Carrying Capability. Accreditation mechanics; if capacity value matters to your fleet, this is the one.

Monday, August 17: VRL Ramp Rates.

Submission Date Alignment closes today, August 12; if it is on your list, it is a same-day turn.

A dozen routine FERC filings also close between August 14 and 19, mostly interconnection agreements and service-agreement housekeeping: ER26-2401-001 and ER26-2403-001 (the Incorporated County of Los Alamos deficiency responses, August 14), the Leeward, Blue Valley Grid, and NextEra interconnection filings (August 14), Avangrid's meter agent agreement (August 14), the SPS NITSA cancellation (August 14), Evergy Metro and North Iowa Municipal NITSA updates (August 17), and two surplus interconnection filings from NextEra Development and Longroad (August 19). Silence on a routine filing is the usual answer; they are here so nothing closes unseen.

What moved

August 11 was closing day: five comment windows shut at once. Interchange Transactions Clarification and Enhancement, Uninstructed Load Deviation, Enhance Forecast Submission, BP 1700 Profiling Transmission Service, and Price Adaptive Load Service all move to their working groups with whatever arrived by the deadline. Intermediate Planning closed August 5.

Coming up

August 20: comments due on the Tariff Clean-Up Filing.

August 21 is a crowded date: the CPP ICS Facility Analysis and Affected System notification revision request, the OMPA NITSA deferral, Empire District's tariff filing, NERC's Risk Management for Third-Party Cloud Services comment period, and six separate Energy Authority PTP agreements (4927, 4930, 4931, 4939, 4940, and 4941), all due the same day.

August 24: Storage Reliability and Flexibility Initiative and BP 7700 RFP Criteria Points Weighting.

August 26 and 27: a run of SPP tariff revisions including Order 831 offer caps and GHG adder updates, the SHOC multiplier update, the Order 719 LSE attestation clarification, and the Markets+ business day definition. Several carry an effective date of 12/31/9998, which is tariff shorthand for indefinitely, not a plan for the year 9998.

September 1: the large-load show cause window closes.

September 23: NERC's CIP-008 reporting threshold modification comment period ends.
