Powerex intends to terminate a large portion of its rights on PacifiCorp’s transmission system in response to the utility’s plans to update its transmission tariff to align with CAISO’s EDAM.

CAISO will be inherently compromised in its role as an operator of a deeper Western market because of its conflicting responsibilities as BA within that market, a group of entities that support SPP’s Markets+ argue in their latest “issue alert.”

Markets+ proponents argue that the SPP framework allows more flexibility for integrating greenhouse gas emission reduction programs across various states than CAISO’s EDAM.

The white paper by The Brattle Group offers a point-by-point comparison of CAISO’s Extended Day-Ahead Market and SPP’s Markets+ that leans in favor of EDAM but stops short of endorsing either market.

CAISO focused on CRRs when it served up the latest volley in the ongoing dispute over what played out on the Western grid during the January cold snap that forced Northwest utilities to import high volumes of energy to avoid blackouts.

Proponents of SPP’s Markets+ contend in their latest “issue alert” that the framework provides a much more equitable solution to tackling market seams than under CAISO’s EDAM.

Enhanced protections against uncompetitive market behavior are among several tools to ensure fair and accurate pricing under a Markets+ framework, according to the latest "issue alert" from entities that back its development.
