Tuas Power's referral code takes $20 off your electricity bill when you switch your home to one of its fixed-price plans. The code is RCZ3HGE. You type it into the online sign-up form, and the rebate lands on your second or third bill. We checked the programme terms in November 2026, and three conditions catch people out: it only covers PowerFIX 24 and PowerFIX 36, it only works through the online form, and you can't add or fix the code after you submit.
How to Use the Tuas Power Referral Code
- Open the Tuas Power residential sign-up form. Roadshow sign-ups don't qualify.
- Choose PowerFIX 24 or PowerFIX 36. The 12-month plan and the PowerFIX 25 G+ green plan aren't part of the referral programme.
- Enter RCZ3HGE in the Campaign / Referral Code field. Check it before you submit, because Tuas Power won't let you change it afterwards.
- Finish the form. Once your account transfers to Tuas Power, the $20 rebate is applied to your second or third bill, depending on your SP billing cycle.
Which Plan Should You Pick?
These are Tuas Power's residential rates as listed in November 2026, against the SP Group regulated tariff of 31.16 cents/kWh (including GST) for October to December 2026.
| Plan | Rate (incl. GST) | Contract | Plan rebate | Referral code works? |
|---|---|---|---|---|
| PowerFIX 36 | 30.63¢/kWh | 36 months | $200 | Yes |
| PowerFIX 24 | 30.90¢/kWh | 24 months | $120 | Yes |
| PowerFIX 12 | 31.15¢/kWh | 12 months | None | No |
| PowerFIX 25 G+ (green) | 32.70¢/kWh | 25 months | $120 | No |
The rate gap against the tariff is small. Take a home using 400 kWh a month: PowerFIX 36 costs about $2.12 a month less than the current tariff, and PowerFIX 24 about $1.04 less. Most of the saving comes from the one-off rebates. The tariff is reset every quarter, so a fixed rate that's slightly cheaper today may end up above or below it next year. You're mainly buying a predictable bill.
Read clause 14 of the referral terms before you count on both rebates. It says the programme "cannot be used with another promotion Program, no further add on of rebates, unless otherwise specified," and it doesn't say whether the $120 or $200 plan rebate counts as another promotion. If the sign-up summary only lists one rebate, ask Tuas Power which one applies before you confirm.
Every PowerFIX plan also came with 12 months of free Singlife insurance cover when we checked.

Frequently Asked Questions
How much is the Tuas Power referral reward?
The new customer gets a $20 bill rebate, inclusive of GST. The existing customer who referred them also gets $20. If the rebate is more than your bill, the balance carries over to the next month until it's used up.
When does the Tuas Power referral programme end?
The current terms run from 1 January to 31 December 2026. Tuas Power can change or cancel the programme without notice, so check the sign-up form before you rely on it.
Can I add the referral code after signing up?
No. The terms say the code can't be amended, added, re-submitted or edited after sign-up. If you leave the field blank, you lose the rebate.
Does the code work for business accounts?
No. The programme only covers residential customers.
Is it worth switching from SP Group's tariff to Tuas Power?
At November 2026 rates, PowerFIX 36 is about 1.7% below the tariff and PowerFIX 24 about 0.8% below. That's a modest saving on its own. Most of the value comes from the $20 referral and plan rebates. You also lock in a price for two or three years, which helps if tariffs rise and costs you if they fall. The referral terms set a $200 early termination charge and let Tuas Power claw back referral rebates when a contract ends early. Only pick the 36-month plan if you expect to stay at the same address.
