In Amendment No. 38, the ISO proposed modifications to Tariff provisions relating to the separation of contingency reserve energy from imbalance energy. Amendment No. 38 gives participants an option to indicate whether energy from Operating Reserve bids should be dispatched only for Contingencies or System Emergencies due to energy limitations. These bids would be separated out from the imbalance energy portion of the BEEP stack and dispatched based on effectiveness only when there is a Contingency or System Emergency. Pursuant to Amendment No. 38, the BEEP Split becomes effective ten days after the ISO posts a notice on the ISO Home Page that the modified software necessary to implement the BEEP Split is ready for use. The ISO software modifications are now complete. The ISO will therefore implement this function on May 22, 2001, starting with the Day Ahead Market for Trading Day May 23, 2001. The ISO is providing this notice to Market Participants via e-mail and will also post this notice on its Home Page.
