25 Market Outlook 25

26 Market Outlook Retail Electricity Supply Final conditions set by the law for commencement of open access and retail competition are nearly met. Retail market will initially cover bulk users with at least 1 MW demand. PEMC is appointed as the Central Registry Body Renewable Energy Market Renewable Energy law passed in 2008 provides for establishment of a renewable energy market by the Department of Energy. Ongoing public consultations on implementing rules and regulations. 26

27 Market Outlook Reserve Market WESM design includes co-optimization of energy and reserves. Tradable reserves include regulating dispatchable reserves. Other ancillary services are procured through long term contracts by the System Operator. Regulatory approval of pricing and cost recovery methodology is still pending. 27

28 Market Outlook Transition to Independent Market Operator Law requires eventual transfer of market operations functions to an Independent Market Operator Philippine Department of Energy is responsible for selection and appointment Development of new Market Management System Hardware obsolescence Enhancements needed to address regulatory and rule changes and auditor recommendations 28
