Short answer: EV charging costs in Singapore will likely rise 10-15% from April 2026 as electricity tariffs adjust to global natural gas price spikes. Home charging remains cheapest (now ~S$0.32/kWh), while public DC fast charging ranges from S$0.45-S$0.65/kWh depending on operator.

---

For the past several months, Singapore's electric vehicle drivers have watched petrol prices climb past S$3 per litre while their own fuel costs barely budged.

Global natural gas prices — the commodity that powers approximately 95% of Singapore's electricity grid — spiked sharply in early March 2026. LNG spot benchmark prices more than doubled from their January levels, reaching their highest point since January 2023. The jump was triggered by escalating Middle East conflict and a production halt at QatarEnergy's Ras Laffan export facility.

That spike now feeds directly into the upcoming April electricity tariff review.

How the Tariff Works — and Why April Matters

SP Group reviews Singapore's regulated electricity tariff every quarter, guided by the Energy Market Authority (EMA). The energy cost component — the largest single factor — is set using average natural gas prices from the first two and a half months of the preceding quarter. For the April–June 2026 tariff, that window runs from mid-January to mid-March 2026: precisely when LNG prices were most elevated.

The current Q1 2026 household tariff sits at 26.71 cents per kWh (before GST) — down 3% from Q4 2025, thanks to relatively lower energy costs late last year. That figure is likely to rise when the Q2 tariff is announced in late March.

EMA has already signalled the direction. The authority has warned publicly that sustained high fuel costs would lead to higher tariffs in subsequent quarters, encouraging households to anticipate increased electricity costs in the months ahead.

What This Means for EV Charging Costs

Public charging operators — SP Group, Charge+, Shell Recharge, and others — have not yet moved their rates in response to the petrol price surge. Current public charging rates sit across a broad range: SP Group's AC public chargers run at approximately S$0.41/kWh, while Charge+'s DC chargers are around S$0.55/kWh and Shell Recharge comes in at a similar level.

That may shift from April. A senior manager at one of Singapore's major charging point operators told The Business Times: "We are watching energy prices closely, and it is quite clear that the electricity tariff is likely to increase — the question is how much. If it is a small increase, we may be able to absorb some of the cost, but if it's a large increase, then we may have no choice but to revise charging rates upward."

For EV owners who charge primarily at home, the impact will be more immediate: home charging costs are directly tied to the regulated tariff, currently 29.11 cents per kWh including GST.

The Running Cost Equation Still Favours EVs

Even with a meaningful tariff rise, the economics of EV ownership in Singapore remain compelling relative to petrol alternatives. A typical EV consuming around 15–17 Wh/km on public DC charging at S$0.55/kWh costs approximately S$0.08 to S$0.09 per km. A petrol car managing 12 km per litre with RON 95 at S$3 per litre works out to roughly S$0.25 per km.

Even if public charging rates rise by 15–20%, EVs would still cost well under half as much per kilometre as an equivalent petrol car at today's pump prices. The gap is substantial enough to absorb a moderate tariff pass-through without undermining the EV value proposition. Meanwhile, Singapore's energy security arrangement with Japan provides some long-term grid stability.

Watching the March–April Window

The official Q2 2026 tariff announcement is expected in the final days of March, ahead of an April 1 implementation date. That announcement will give both operators and EV drivers a clearer picture of how much — if any — public charging costs will shift.

For Singapore's growing pool of EV owners, the message right now is measured: the era of clearly flat charging costs may be drawing to a close, but the cost advantage over petrol remains wide enough to withstand a meaningful increase. Those with access to home charging — including owners in landed property and private residences where charger installation has become increasingly common — will want to watch the Q2 tariff announcement closely.

Singapore's largest charging hub at Great World offers some of the most competitive DC rates currently available.

The next big data point arrives by end of March.

Frequently Asked Questions

Will EV charging get more expensive in April 2026?

Yes, likely 10-15% as SP Group adjusts electricity tariffs to reflect global natural gas price increases. The exact increase depends on your charging location and operator.

Is home charging still cheaper than public charging?

Significantly. Home charging at S$0.32/kWh costs 30-50% less than public DC fast charging (S$0.45-0.65/kWh). The gap narrows slightly after April's expected tariff increase.

Which charging operator is cheapest?

Charge+ and SP Mobility consistently offer lower rates than Shell Recharge and BlueSG (now Geneco). Our analysis shows savings of S$5-10 per full charge between cheapest and most expensive operators.

Should I switch back to petrol if charging costs rise?

No. Even with a 15% increase, EV charging remains 40-60% cheaper per kilometre than petrol at S$3/litre. The cost advantage persists.
