Which term is used to describe the RUC process after the DRUC?

• C. CRUC
• D. URUC

Answer: (B)

Reliability Unit Commitment is run in stages to ensure enough generation for the expected load and reserves. After the day-ahead Reliability Unit Commitment, the next step is the Hourly Reliability Unit Commitment. This hourly adjustment ensures the upcoming hour has the right mix of committed units based on updated load forecasts, outages, and other real-time conditions. It may bring additional units online or adjust commitments to maintain reliability for that hour. The day-ahead step sets plans for the whole next operating day, while the hourly step tightens those plans to the immediate hour. Other terms aren’t used for the ERCOT process in this sequence, so the hour-by-hour commitment adjustment is the correct term.
