Tuas Power Supply Singapore — Comparison & Review of Tuas Power Electricity Plans

tuas power supply review singapore

Now that the Open Electricity Market (OEM) has been rolled out, all households in Singapore can switch away from SP Group and choose their preferred electricity retailer. There are currently 12 electricity retailers in the market, including Tuas Power Supply.

Tuas Power has always been a big name in the industry (since 1995): as one of the leading power generation companies in Singapore, they generate and retail their own energy. Compared to electricity retailers that have to buy from power plants and then sell to consumers, it’s one less middleman in the way.

That may be reassuring to some, but the truth is that most of us are more concerned about the dollars and cents. How price competitive is Tuas Power Supply? Let’s compare their electricity price plans to find out.


Tuas Power Supply review (TLDR)

If you’re lazy to read the whole article, here’s what we found:

Unlike some other retailers who offer non-standard plans — e.g. peak/off-peak pricing, etc —  Tuas Power Supply only offers the 2 standard types: fixed rate and discount off regulated tariff.

There are 5 residential electricity plans in total, and price-wise, they aren’t very cheap.

However, they do have quite attractive promotions and a very lucrative referral programme (Referral+). This translates to up to $100 savings in bill rebates, and up to $20 per referral.

Additionally, Tuas Power Supply does their billing through SP, so if you hate administrative hassle, this is a bonus. All your utility charges will come in a single bill under SP, as it always has.

All prices include the transmission loss factor (i.e. you won’t be charged for it).

The above table is an overview of Tuas Power Supply’s electricity plans for residential households. The cheapest one is currently the fixed price plan (all contract durations).

Tuas Power Supply — fixed rate electricity plans

Tuas Power Supply fixed rate plans Price per kWh  Contract duration 
T Power FIX  17.98¢ 18, 24 or 36 months 

At 17.98¢ per kWh, Tuas Power Supply’s fixed rate plan is 28% cheaper than the current tariff of 25.07¢ per kWh (1 Oct to 31 Dec 2019). 

Interestingly, the price is the same for all contract durations, be it 18, 24 or 36 months. This is unusual — most other retailers offer better rates for the 2- and 3-year contracts so they can lock-in your business. The longer the better mah.

And it’s not even because Tuas Power Supply’s rate is so good that they don’t need to bother with incentives… At the moment, they’re not even in the top 5 cheapest fixed rate plans. The lowest fixed rate plan is currently by Geneco (17.62¢ for 6 month contract, 30% off current tariff).

Tuas Power Supply is definitely not the cheapest, but if you just want to switch and prefer an established player in the energy market, then you can consider signing up. After all, 28% savings is quite significant.


Tuas Power Supply — “discount off regulated tariff” electricity plans

Tuas Power Supply discount off regulated tariff plans Price per kWh  Contract duration 
T Power DO 22% off tariff 24 months 
T Power DO 18% off tariff  6 months 

If you prefer to peg your electricity rate to the regulated tariff (which is revised every quarter, 4X a year), then you can opt for “discount off regulated tariff” plans.

Again, Tuas Power Supply’s plans are quite ummm, unique. Most other retailers have 1-year options, which seem to be the most popular. But for Tuas Power Supply, you will have to sign up for either a very short 6 months, or a very long 2 years.

The 6-month plan only gives you 18% off the tariff, while the 24-month one gives you 22% off. Although it’s comparatively better, if you pit it against other retailers, it is poor. Right now, the more competitive retailers are offering 23% to 25% off the tariff.

The cheapest one at the time of writing is 25% off by Diamond Electric (12-month contract) and Ohm Energy (6- or 12- month contracts).


Tuas Power referral code programme (Referral+)

I was doing some digging while researching Tuas Power Supply and found there is quite a bit of conversation surrounding Referral+, which is their referral programme. People are even designing their own referral code banners okay…

Nah, extra publicity for these people who put in so much effort. Hopefully they will share the “commission” with me.

Initially, I just thought everyone was being very shameless and “kiasu” about earning some extra rebates… But who knew they actually had quite a good reason to?!

Compared to everyone else, Tuas Power Supply’s referral programme is next level… And by that I actually mean multi-level; as in multi-level marketing (MLM).

Like most referral programmes, both the referrer and referee will receive bill rebates for each successful referral. If I refer you, we both get money — simple as that. But for Tuas Power Supply, the difference is that you will earn $5 to $20, via 3-tiers of “commission”, from 3 degrees of referrals.

Here’s the example taken from Tuas Power’s website:

When you refer your friend Alice (Tier 1), you will get $20. When Alice refers her friend Bernice, you will get $10 (Tier 2). When Bernice refers another friend Calvin, you will get $5 (Tier 3).

Power, right?!

When you sign up with Tuas Power, you will automatically receive your own referral code (via SMS and in your confirmation letter). Your friend (the referee) will need to key in your referral code (the referrer’s) in the “Campaign / Referral Code” field in the sign up form.

Do note that this will take 3 to 6 weeks to process, and is only valid for online sign-ups. So don’t even think of randomly approaching people at roadshows — it won’t work.


Tuas Power promotions & roadshows

On top of the referral programme, Tuas Power Supply has several ongoing promotions. Play your cards right – literally — and you can be seeing savings of over $100.

Up to $100 bill rebate

If you’re a new customer who signs up online, you can get a $60 bill rebate for the 18- and 24-month plans, and $100 bill rebate for the 36-month plans. This promo is limited to the first 2,000 sign-ups only, from 1 Jul 2019.

The $60 or $100 is a bill rebate (not cash), which will be credited to your second/third bill, depending on your SP bill cycle. If your bill is under $100, it will roll over until it is fully utilised, so don’t worry about that.

Free 1-year Aviva insurance

Also, all Tuas Power Supply customers can pick a complimentary 12-month plan from Aviva for either Personal Accident, Home or Travel insurance coverage. You just need to select it in your application form.

After that, an Aviva Relationship Consultant will reach out to you (around 2 weeks later). They will then help you apply for the free insurance coverage.

Earn NTUC LinkPoints

Tuas Power Supply is a partner of NTUC Plus!, so you can earn NTUC Plus! members can earn 1 LinkPoint for every 8kWh of electricity consumed.

Assuming you live in a 4-room flat with an average consumption of 360 kWh per month, you will earn 45 LinkPoints. That’s the equivalent of spending $22.50 on grocery shopping at NTUC Fairprice.

Up to $1 off monthly with POSB Everyday Card

To further shave $1 off your monthly bill, you can use your POSB Everyday Card. One of the card’s benefits is that it offers 1% cash rebate for your Tuas Power Supply bills, but capped at $100 spend.

Since your electricity bill will be consolidated with the rest of your utilities (Tuas Power Supply does billing through SP), the $100 cap is for your total SP bill. That just means you can get maximum $1 off monthly.

There is no minimum spend required to enjoy this cashback.

Of course, the above-mentioned promotions are for online registrations. If you’re interested in finding out the roadshow-exclusive discounts and bundles, you can check the official Tuas Power Supply roadshow page.
