Change Request 2025-CRF-008

The WRAP Forward Showing deliverability requirement established the Forward Showing firm Transmission requirement which is currently defined as firm transmission from source to load for 75% of the Monthly P50 Load forecast plus the monthly FSPRM.  The availability of NEW long term firm transmission across the west is very constrained and expected to persist into the future.   Removing the PRM share of the current Forward Showing Transmission requirement would remove participants’ obligation to acquire long-term firm transmission from source to load beyond their expected load service, while still preserving the 75% long-term firm transmission requirement.   Participants continue to acquire short-term firm transmission to reliably serve load after the Forward Showing deadline.

Removal of the PRM from Forward Showing Transmission Requirement. In all references to the definition of FS Transmission requirement replace FS Capacity Requirement with P50 Load Forecast.

(and Forward Showing Instruction Manual)

In all references to the definition of FS Transmission requirement replace FS Capacity Requirement with P50 Load Forecast.

BPM 106 Qualifying Contracts – added clarification of P50 loads on transmission requirements (and general abbreviation cleanup)

BPM 107 Forward Showing Deficiency – update to deficiency calculation (and general cleanup of citations)

BPM 108 Forward Showing Submittal Process – replace ‘FS Capacity Requirement’ with ‘P50 Peak Load Forecast’ in Transmission Requirement, ‘P50 Peak Load Forecast’ is already a defined term. 

Change reduces the burden on participants to acquire long-term firm transmission 7 months in advance of flow, in order to meet the P50 Peak Load plus the PRM requirement, in an environment where new additional long-term firm transmission is not available. Participants purposely chose not to require 100% of transmission for load service so that the uncertainty of long term load forecasts could be managed more efficiently by utilizing the short term transmission market. Requiring acquisition of long term firm transmission for PRM plus 75% of P50 load erodes the efficient use of transmission and is likely to force participants to over invest in transmission even if it was available.  Participants are planning to serve load, their own transmission acquisition of firm transmission should be aligned with that principle to assure deliverability to load.
