Currently, businesses with an average monthly consumption of at least 2,000 kWh (equivalent to a monthly electricity bill of at least $400) are eligible to choose their electricity provider. They can exercise their choice of buying electricity, or from the wholesale electricity market at half-hourly prices (i.e. become contestable).

If you are an eligible business consumer, you can add up your electricity usage across different locations in Singapore to meet the consumption threshold. Find out if you are eligible to exercise your choice here.

With the soft launch of Open Electricity Market from April 2018, households and businesses in Jurong can choose to buy electricity from a retailer with a price plan that best meets their needs. This would involve consumers whose premises have postal codes starting with 60, 61, 62, 63 and 64.

Note that consumers who are under the Pay-As-You-Use (PAYU) metering scheme with SP Group can only switch to a retailer after clearing all outstanding arrears owed to SP Group.


Contestability for Consumers under Master-Sub Metering Arrangement

Master-metered account holders can only exercise their choice of electricity provider under the following schemes:

En-Bloc Contestability Scheme

Under the En-Bloc Contestability Scheme, the master-metered account holder will buy electricity for the entire premises on behalf of all his tenants. The consent of all tenants is required for the master-metered account holder to become contestable under this scheme.

Note that if any of the tenants subsequently withdraws consent for the master-metered account holder to buy electricity for his premise on his behalf, the contestability status of the master-metered account holder will be revoked. All consumers at the premises will revert to buying electricity from SP Group at the regulated tariff as non-contestable consumers.

Learn more about the En-Bloc Contestability Scheme Guidelines.

Demand Aggregation Scheme

A master-metered account holder who is unable to obtain the consent of all the tenants may become contestable under the Demand Aggregation Scheme. Under this scheme, the master-metered account holder can carve out part of his common services load and the load of one or more consenting tenants for contestability under a sub-metered account. The remaining tenants who do not wish to be part of the scheme can continue to buy electricity under their preferred electricity supply arrangement.

Note that if any of the consenting tenants subsequently withdraws consent for the master-metered account holder to buy electricity for his premise on his behalf, the contestability status of the master-metered account holder will be revoked. All consumers under the scheme will revert to buying electricity from SP Group at the regulated tariff as non-contestable consumers.
