Billing & Payment Methods

eGIRO

 eGIRO (Electronic GIRO) is a nationwide digital initiative that fully digitises the GIRO application process. It significantly reduces GIRO set-up turnaround time, allowing customers to set up recurring payments more efficiently and conveniently.

Traditional paper-based GIRO applications may take up to 8 weeks to process and often require customers to make manual payments while approval is pending.

With eGIRO, the application process is completed digitally, and approval typically takes less than 48 hours. This reduces processing delays, avoids manual interim payments, and allows customers to start automated payments sooner.

Customers can apply for eGIRO directly through the Tuas Power website by selecting their designated bank.

Customers can only create an eGIRO instruction through the Tuas Power website. Applications via participating banks’ websites or mobile applications are currently not supported.

There is currently no charge for creating an eGIRO instruction through the Tuas Power website.

Tuas Power recognises the importance of data security and has implemented stringent safeguards to protect customers’ personal data during the eGIRO application process.

All data transmitted is encrypted. Only the authorised bank and Tuas Power are able to decrypt the information for the purpose of processing the requested transactions.

The authentication and authorisation process is secured by the bank’s two-factor authentication (2FA) and transaction signing protocols.

eGIRO does not replace the existing paper GIRO arrangement. Customers may continue to use paper GIRO if they prefer.

Alternatively, customers may visit the website to set up recurring payments via eGIRO.

There are eight participating banks under the eGIRO initiative:

Customers should contact their designated bank if they require any further assistance.

Setting up an eGIRO is easy and quick. Simply follow the steps below!

  1. Select eGIRO as payment mode on Tuas Power website and fill in the relevant details.

  2. Ensure that the eGIRO setup has been authorised by the designated personnel within 48 hours. (Only
    applicable if customer is applying under a Corporate bank account*)

  3. Once the customer clicks on “Apply now”, the designated bank’s internet banking login page will be
    launched, for the customer’s secure log in with his or her user ID & password.

  4. Customers should select the bank account that they wish to make payment from to complete their eGIRO setup and submit their application.

  5. Customers will be redirected back to Tuas Power website to view their submission status. They will
    receive confirmation from the bank and Tuas Power within 48 hours informing them of their application status.

Please note that once submitted, eGIRO instructions cannot be amended through the Tuas Power website. If customers wish to make changes, they may cancel the existing eGIRO arrangement via their Internet Banking portal before submitting a new eGIRO application.

This depends on the selected bank. Some banks allow customers to specify an end date during the eGIRO setup process, while others do not offer this option.

If an end date cannot be selected, the eGIRO instruction will be valid for one year from the date of approval by default.

If you encounter an error during the eGIRO application process, try out the following :  

  • clear the browser cache 

  • use a different browser

  • restart the computer or mobile device.

If the issue persists, please contact Tuas Power via Contact Us Form or reach out to the respective bank for further assistance.

Each eGIRO application applies to one premises address with a unique TPS Account Number.

If a business has registered multiple premises with Tuas Power, the customer will need to submit separate eGIRO applications for each premises.

Customers will receive an email or text message from Tuas Power and/or their selected bank within 48 hours to inform them of their eGIRO application status.

After completing the eGIRO setup through your bank’s portal, you will be redirected back to the Tuas Power website, where your submission status will be displayed.

  • If the application was submitted successfully, you will see a screen that indicates “eGIRO SUBMISSION SUCCESSFUL.”

  • If the application was not submitted successfully, you will see a screen that indicates “eGIRO SUBMISSION FAILURE.” In such cases, you will need to resubmit a fresh eGIRO application.

An eGIRO application may be unsuccessful due to the following reasons:

  • No approval from authorisers to complete the eGIRO setup

  • The session was inactive for an extended period

  • The browser window was closed before finishing the eGIRO setup

  • The application process was not fully completed on the banking portal

If an eGIRO application is rejected, Tuas Power will notify the respective  customers  via email with the specific reason.

The email will include guidance on the next steps needed to submit a new eGIRO application accordingly.

Cheque Free Payments

In support of Singapore’s move towards electronic payments, Tuas Power ceased accepting and issuing cheques from 1 October 2023.

To facilitate a smooth transition, cheques received up to 31 December 2023 were processed at a charge of S$25 per cheque. Customers are encouraged to use alternative electronic payment methods.

This change supports Singapore’s national initiative to go cheque-free by 2025, as announced by the Monetary Authority of Singapore (MAS), and helps customers transition to faster and more efficient electronic payment methods.

  2. Maybank

  3. Oversea-Chinese Banking Corp

Taxes & Government Charges

Carbon Tax

A carbon tax is a tax imposed on carbon dioxide (CO₂) emissions, which mainly arise from the combustion of fossil fuels used in electricity generation, heating, and transportation.

In Singapore, carbon tax is a carbon pricing scheme implemented on 1 January 2019 to support the nation’s climate mitigation efforts and long-term net-zero targets.

The Grid Emission Factor (GEF) measures the amount of carbon emissions generated per unit of electricity produced. It reflects emissions from all electricity generation sources connected to the grid, including natural gas, solar, and waste-to-energy.

This factor is determined and published by the Energy Market Authority (EMA).

Singapore’s carbon tax was set at S$5 per tonne of CO₂-equivalent (tCO₂e) from 2019 to 2023.

From 1 January 2024, the carbon tax will be increased to S$25 per tCO₂e to support Singapore’s net zero target. The carbon tax is expected to continue rising progressively and is expected to reach up to S$80 per tCO₂e by 2030.

The increase in carbon tax strengthens price signals for businesses and individuals to reduce carbon emissions and adopt cleaner energy sources.

This supports Singapore’s decarbonisation strategy and national climate commitments as outlined by the National Climate Change Secretariat.

With the rise in carbon tax, Tuas Power will be revising our Tuas Power Carbon Tax Charge accordingly as the Carbon Tax Rate is one of its components. As a result, our carbon tax charge will be revised to $0.01809/kWh.

Please see below for an example of how the carbon tax charge is being computed by Tuas Power:

Starting from 1 January 2026, the GEF rate of 0.402 kg CO₂ per kWh will be applicable and shall be passed through to consumers.

This will be reflected in the carbon tax charges of the  electricity bill.

Tuas Power is committed towards the journey of going green and supporting Singapore’s transition towards net zero goal by actively exploring ways to reduce carbon emissions and improve energy efficiency which will result in less cost being passed on to customers.

At the same time, Tuas Power remains committed to keeping electricity prices affordable and competitive for customers.

Customers may reduce the impact of higher carbon tax charges by adopting energy-efficient practices and using energy-saving technologies.

Reducing overall electricity consumption can help lower total electricity costs, including carbon-related charges.

Third-Party Charges

Third-party charges may include regulated fees related to electricity transmission, metering, or market operations. These charges are determined by relevant authorities.

Third-party charges are regulated and applied consistently across retailers.
