Uneconomic adjustment policy

The primary purpose of the Parameter Tuning effort is to determine the values for the various Uneconomic Adjustment parameters – i.e., the penalty prices – to be used in the MRTU market software at the start-up of the MRTU markets and in the final phase of Market Simulation leading up to the market start-up. There are several ways to classify the various penalty prices to be studied in this effort: (a) scheduling run parameters and pricing run parameters; (b) Self Schedule parameters and constraint parameters; and (c) Day Ahead Market parameters and Real Time Market parameters. As a result of the Uneconomic Adjustment Policy effort the California ISO (the ISO) anticipates making a filing at FERC in July to amend certain related provisions of the MRTU Tariff.
