Line 30: * C is capable of 50 MW at $120/MWh (from 200 to 250 MW of system power). At the expected demand is 150 MW (a vertical line on the graph), unit A will be engaged at full 120 MW power, unit B -will run at the '''dispatch level''' of 30 MW ~~power~~, unit C will be kept in reserve. The area under the dispatch curve to the left of this line represents the cost per hour of operation (ignoring the startup costs, $30 * 120 + $60 * 30 = 5,400), the incremental cost of the next MWh of electricity ($60 in the example, represented by a horizontal line on the graph) is called '''system lambda''' (thus another name for the curve, ''system lambda curve'') == Minutes-ahead operation ==
