Becoming a Retailer

Licensed electricity retailers are companies authorised by the Energy Market Authority (EMA) to retail electricity to contestable customers.

There are two types of electricity retailers: Market Participant Retailers (MPRs) and Non-Market Participant Retailers (NMPRs).

MPRs have to be registered with the Energy Market Company (EMC) to purchase electricity from the National Electricity Market of Singapore (NEMS) to sell to contestable consumers.

NMPRs need not register with EMC to participate in the NEMS, since they will purchase electricity indirectly from the NEMS through the Market Support Services Licensee (MSSL).

For more information on becoming a retailer, please refer to EMA’s Guide to Becoming a Licensed Electricity Retailer
