​Business FAQs


What does contestable mean?

Contestable businesses are those who are eligible to buy electricity from retailers of their choice outside of SP Powers.

If your business has a monthly consumption of above 2,000kWh (equivalent to a monthly electricity bill of at least $400) and will be eligible to choose their electricity provider.

Check your eligibility here.

Am I eligible to switch?

Only contestable businesses can buy from Senoko today. Please refer to the Open Electricity Market website to check the criteria to know your eligibility to make the switch.

Contestable businesses can buy from electricity retailers the same way they do today. When EMA officially liberalises the market, there will be additional approved electricity retailers for these businesses to buy from.

Businesses who are master-metered account holders for premises under the master/sub metering scheme. Such customers can only switch to become market consumers under En Bloc Contestability Scheme (EBS) or the Demand Aggregation Scheme (DAS).

If you are a contestable customer and are buying from an electrical retailer today, please ensure you have already fulfilled your contractual obligation.

What’s the difference between an AMI meter and a SRLP Meter?

An AMI meter allows for a more accurate reading as it reads electrical consumption every half hourly, whereas the SRLP meter are read by MSSL every 2 month.
