The government has progressively liberalised the retail electricity market to promote the efficient supply of competitively priced electricity, with plans to open up the market eventually to full competition. The introduction of competition among the retailers has benefitted contestable consumers with improved services, greater efficiency, competitive prices and innovative products.

The liberalisation of the retail electricity market is intended to give eligible consumers more options to manage their energy cost. While retail market liberalisation does not necessarily mean that prices will come down, competition among the retailers will encourage competitive pricing and product innovation for the benefit of consumers.

As market prices for electricity depend on the supply and demand situation, there will be up cycles and down cycles. The price of electricity to different consumers may also differ depending on their individual consumption needs. For instance, some consumers may be prepared to pay a premium for a firm electricity price i.e. fixed price retail contracts versus fuel price indexed retail contracts.

The Energy Market Authority (EMA) does not price-regulate the retailers. The “Code of Conduct for Retail Electricity Licensees” sets out the minimum standards of performance that all retailers must comply with.

  • Electricity retailers can provide packages with different price plans and services to suit differing usage patterns. If you decide to buy electricity from them, you will be billed directly by your retailer based on thecommercially agreed electricity price.
  • If you buy electricity from the wholesale electricity market, your electricity charges will be based on prices that vary every half-hour depending on the prevailing demand and supply situation. You can buy from the wholesale electricity market (a) through SPS or (b) by registering with the EMC as a DMC.
  • The option of buying electricity as a DMC is typically for very large consumers, as they need to meet certain financial, technical and operational requirements. Under this option, you will be billed by the EMC on a daily basis. For more information on buying electricity directly from the wholesale electricity market, please visit the EMC's website.
  • It is not compulsory for you to switch to become a contestable consumer. No action is required from you if you choose to stay as a non-contestable consumer and continue to buy electricity from SPS at the regulated tariff.
Prior to 1 April 2014, contestable consumers are metered using Time of Day (TOD) meters. These meters are remotely read using telephone lines. From 1 April 2014 onwards, SP PowerGrid (SPPG) will install the Advanced Metering Infrastructure (AMI) meters for all new contestable consumers.
If you are a contestable consumer with the AMI electricity meter, you will need to pay a monthly meter charge of $1.83 per single-phase meter and $2.49 per 3-phase meter. This will be capped at $12.50 if multiple meters are required at your premises.
For consumers taking electricity supply of up to 100A, SPPG would need to temporarily interrupt your power supply for no longer than 30 minutes for the installation of AMI electricity meters. For larger consumers, there is no supply interruption during the installation of the meters.
You can switch off your incoming supply via the circuit breaker located after the AMI meter. If you decide to switch off your power supply by turning off the incoming circuit breaker before the meter at the meter board, it will affect the communications connectivity of the AMI meter. Hence you will have to inform your electricity provider at least 7 business days in advance before you perform this temporary disconnection
Upon finalising the commercial details with the retailer of your choice, your electricity retailer will submit a transfer request to the Market Support Services Licensee on your behalf. SPS will need at least one business day to process the transfer.
Contestability applications for normal metered accounts and master metered accounts will be approved within 2 and 4-5 business days respectively. This does not include the time needed to install or replace any metering equipment.
All new contestable consumers will need the Advanced Metering Infrastructure (AMI) meters which will be installed by SP PowerGrid (SPPG). Please make an appointment with SPPG for the installation of the meter.
No. SP PowerAssets (SPPA), as the transmission licensee, remains responsible for the physical delivery of electricity supply to your premises regardless of which option you choose. Hence, you will continue to enjoy the same quality, safety and reliability of electricity supply if you choose to become contestable.
SPPG maintains the transmission and distribution network on behalf of SPPA. Please contact SPPG at 1800-778 8888 (24-Hr Electricity Service Centre) to report any problems with your electricity supply.
