On Mar 29, 2012 the ISO revised its default operations and maintenance cost adders, which represent the per-megawatt hour variable, non-fuel costs of running a generating unit at or above its minimum operating level. The ISO increased the number of adder values from two to ten to differentiate costs by technology for all generation resources participating in the market. The ISO will re-evaluate these values every three years.
