What is the Peaker net margin in ERCOT?
The Peaker Net Margin (PNM) is used by ERCOT and its market monitor as a measure of generators’ economic rent.

Is ERCOT a capacity market?
Unlike other grid operators, the Electric Reliabiltiy Council of Texas (ERCOT) operates only an energy market to meet customer demand and does not use a capacity market to ensure necessary resources will be available. Instead, the state depends on the promise of higher prices to incentivize generation.
Does ERCOT set rates?
