Retail Competition and Open Access (RCOA) allows electricity end-users who have a choice to choose their supplier of electricity with an average demand set by the Energy Regulatory Commission (ERC) -- at least 500kW for Competitive Retail Electricity Market (CREM) and Electricity Retail Aggregation Program (ERAP), and at least 100kW for Green Energy Option Program (GEOP). This is in accordance with Section 31 of the Electric Power Industry Reform Act of 2001 (RA 9136). Eligible end-users may now secure Retail Supply Contracts (RSCs) from licensed/authorized Suppliers. The Central Registration Body shall be responsible for undertaking the required process, information technology, and other systems capable of handling customer switching and information exchange among participants. These developments in the retail market is envisioned to herald more quality, security, and affordability in electricity trade and promote further transparency, dynamism and competition in the WESM.
