ERCOT system worked 'as expected' during Tuesday price spike: staffer

摘要

The Electric Reliability Council of Texas' market operated "as expected" when real-time wholesale power prices hit the systemwide offer cap of $9,000/MWh during Tuesday's early-morning ramp up in power demand, stakeholders heard Thursday. At the end of Thursday's meeting of ERCOT's Technical Advisory Committee, Chairman Bob Helton asked Dave Maggio, manager of market analysis and validation for the grid operator, to give a "highlevel" explanation for why prices surged into the high four-digits Tuesday. Real-time power spiked to $5,800/MWh for 15 minutes Tuesday morning, while the grid operator deployed non-spin reserves around the same time. In addition, real-time prices hit the current energy offer cap of $9,000/MWh during two five-minute intervals.
