Retail Competition and Open Access (RCOA) introduces retail competition to the power industry. The retail market has created an opportunity for electricity end-users with an average peak demand of at least 1MW to secure retail supply contracts from licensed Retail Electricity Suppliers (RES) or Local RES. PEMC, as the Central Registration Body, is determined to cater to the needs of its expanding clientele with the entry on new contestable customers as the threshold level is further reduced to 750 kilowatts (kW). At this level and beyond, new entities or business function called Aggegators shall be allowed to supply electricity to end-users whose combined demand within a contiguous area is at least 750 kW. This development 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.
