Plans, Pricing & Eligibility

Open Electricity Market (OEM)

The Open Electricity Market is the final phase of Singapore’s electricity market liberalisation. It allows all residential households and businesses to choose their preferred electricity retailer.

All households in Singapore are eligible to switch from SP Group’s regulated tariff to another electricity retailer under the Open Electricity Market (OEM).

However, customers under the Pay-As-You-Use (PAYU) metering scheme with SP Group must first clear any outstanding arrears with SP Group before they can proceed with the switch.

Once outstanding balances are settled, the switching process can be completed without any interruption to the electricity supply.

Switching to an electricity retailer is entirely optional. Consumers who prefer to remain with SP Group can continue  to buy electricity from SP Group at the regulated tariff.

However, switching to Tuas Power allows you to enjoy competitive electricity rates and significant savings, while your existing billing and payment arrangements with SP Group remain unchanged.

Electricity Plans

PowerFIX is a fixed-rate electricity plan that lets customers lock in  a set electricity rate for the entire contract duration, giving them  long-term price certainty.

This means that even if the regulated tariff fluctuates, the  electricity rate remains unchanged, giving  greater stability and predictability over the electricity costs.

PowerDOT is a discount-off-tariff (DOT) plan that offers a fixed percentage discount off the regulated tariff.

This means that regardless of how the regulated tariff fluctuates, the electricity rate will always remain lower than the prevailing regulated tariff, ensuring guaranteed savings throughout the  contract period.

Tuas Power offers both fixed-rate electricity plans (PowerFIX) and discount-off-tariff electricity plans (PowerDOT).

The most suitable plan depends on the customer lifestyle and electricity usage habits. It is always good to review the available plans to choose the one that best meets your needs.

Tuas Power offers both Standard and Non-Standard electricity plans to suit different consumer  preferences.

Our fixed-rate plans with a 36-month contract duration are classified as Non-Standard Plans,  because the contract periods differ from the EMA standard durations of 6, 12, or 24 months. These plans are offered to customers who prefer longer or alternative contract durations.

  • For Standard Plan Auto Renewals,  the plan must remain the same plan type as the initial contract. For example, a Discount Off Tariff Plan will renew as a Discount Off Tariff Plan.

  • For Non-Standard Plans, auto-renewal does not need to follow the same product type. Customers may renew to either a Fixed Plan or a Discount Off Tariff Plan, provided that the renewal rate is lower than the regulated tariff at the point of renewal.

Yes, carbon tax is included in Singapore’s electricity pricing framework. All our residential electricity price plans already absorb the carbon tax, so there will be no additional charges added separately to the customer bill!

Yes, all Tuas Power standard and non-standard price plans are inclusive of applicable transmission loss charges and other regulated components.

The published electricity rate is determined after taking these applicable charges into consideration, and no transmission loss fees are billed separately.

Customers may change to another electricity plan, subject to the terms of their existing contract.

If you change plans before your initial contract expires, an early termination fee of S$200 is applicable.

If a customer  wishes to switch plans at renewal, they may simply notify Tuas Power of the  preferred plan and intended start date at least one month in advance, and we will make the necessary arrangements for them.

U-Save Rebate

Yes, eligible residential customers will continue to receive U-Save rebates.

Your billing arrangement with SP Group will remain the same even when you switch to Tuas Power. Therefore, any U-Save rebates from SP Group or Tuas Power bill rebates that you are eligible for will still continue to apply to offset your electricity bill.

The U-Save rebate is applied as a credit to eligible households’ SP electricity bills and will still be reflected if you have signed up for a Tuas Power electricity plan.

It does not affect the electricity rate, but helps reduce the  overall bill amount.

If you are eligible, the U-Save rebate will continue to be credited to your utilities account even when have signed up for Tuas Power electricity plan, and it will automatically offset part of your electricity bill. Yes. If you are eligible, the U-Save rebate is credited directly to your utilities account and automatically offset against your electricity charges. 

Sign-Up & Switching

Sign Up

Once Tuas Power receives the completed online application and required documents, the switching process typically takes about 2 to 3 weeks to be completed.

The  application will be submitted to SP Group based on the preferred transfer date. If the preferred date cannot be accommodated, SP Group will assign an alternative transfer date and notify the customer directly, including any updates related to applicable security deposit.

There are no additional third-party fees or charges to switch from SP Group to Tuas Power.

Tuas Power’s standard and non-standard electricity plans do not include recurring monthly fees. The electricity rate you signed up for will apply for the duration of the contract period, and no extra recurring charges will be added.

For verification and consent purposes, the sign-up should be completed by the SP electricity account holder.

If the account holder needs help with the sign-up, they may reach out to us via the Contact Us form, and our team will be happy to assist.

Signing up is quick and hassle-free. Just follow the simple steps below and Tuas Power will handle the rest.

Step 1: Choose an electricity plan that fits you to a T.

Step 2: Ensure that you have read through the advisory note, factsheet and terms and conditions that contain important information of your chosen electricity plan.

Step 3: Sign up on our website, or at any of our roadshows! Tuas Power will handle the transfer for you.

Alternatively, you may leave your contact details with Tuas Power and we will get in touch with you to assist with the sign-up process.

In Singapore, households are required to open a utilities account with SP Group for the supply of utilities such as electricity, water, gas, and refuse collection.

If you are moving houses, you will need to close your current utilities account with SP Group and open a new account for your new address.

After your utilities account is set up, you may sign up with Tuas Power. If you are an existing Tuas Power residential customer, you can inform us via the T+ Portal and we will submit a transfer request for your electricity account on your behalf.

For more information on opening or closing a utilities account, you may refer to the SP Group website.

You do not need to inform SP Group when switching to Tuas Power. The switching process is handled by Tuas Power on your behalf once your application is submitted.

  • A tenancy agreement, if you are the tenant of the premises

(1) Your current electricity retailer 

(2) 10-digits MSS account number

(3) A copy of your latest electricity bill and SP bill for our reference.

As SP Group is the billing agent, you may be required to top up your security deposit with SP Group which was previously partially refunded when you switched retailers. (This does not apply if your current retailer also uses SP Group as its billing agent.)

If you require a different commencement date, you may contact Tuas Power to request a change. All changes are subject to confirmation by the relevant parties. Customers are encouraged to consult their current retailer regarding any existing contract obligations.

Should you require further assistance, please contact contact us via the Contact Us Form.
