Suboptimal Unit Commitment from Deterministic Dispatch Models
Definition
Traditional deterministic optimization in unit commitment and economic dispatch ignores renewable uncertainties, leading to higher total costs, more start-up/shutdown cycles, and increased wear on coal-fired power plant units. Stochastic models reduce these by accounting for wind/solar variability in dispatch. This causes recurring poor decisions in day-ahead and intraday markets.
Key Findings
- Financial Impact: $Reduced by stochastic model (exact baseline overrun not quantified)
- Frequency: Daily
- Root Cause: Lack of uncertainty modeling in UC/ED, relying on fixed inputs

Financial Impact
$1.2M-$2.1M annually (municipal utility operating ~100-150 generators, 2-4% operational cost overrun) • $1.5M-$2.8M annually (municipal utility trading floor: 2-4% operational cost overrun + opportunity losses from suboptimal market positioning) • $1.8M-$3.2M annually (accelerated coal unit wear, unplanned outages, emergency repairs, reduced plant lifetime value)
Current Workarounds
Boiler/turbine engineer tracks cycling in maintenance logs (paper or database); schedules reactive repairs after failures; informal communication with control room on equipment limits • Compliance manager tracks emissions manually from operational logs; applies emission factors retroactively; uses historical average to forecast compliance risk • Conservative fuel procurement (over-purchase to hedge uncertainty); manual coordination calls with Plant Manager on likely commitment levels; Excel forecasts based on historical capacity factors
