CAISO has kicked off an effort to implement major changes in the way it procures backstop generation needed to maintain grid reliability.

The California PUC (CPUC) will vote on a proposal to replace reliability-must-run contracts between CAISO and Calpine.

CAISO unveiled its latest revisions to a program meant to compensate uneconomic generation units needed to maintain reliability.

A CAISO proposal released would allow power producers to temporarily suspend the operations of unprofitable generators not needed for system reliability.

CAISO stakeholders voiced skepticism about the effectiveness of a new ISO initiative to prevent early retirement of unprofitable generators.

The CAISO Board of Governors approved an ISO request to designate two Calpine natural gas-fired plants as reliability-must-run (RMR) despite criticism.
