What Causes the Electricity Tariff to Increase in Singapore?

Electricity Tariff in Singapore

Key Takeaways

An increase in Singapore’s electricity tariff may be due to global increases in natural gas prices, as most of the country’s electricity is generated using imported natural gas.
Singapore relies heavily on imported natural gas to generate electricity, so overseas events can affect local bills.
Tariffs are reviewed every quarter, which means prices can move up or down throughout the year.
Your bill is affected by both the tariff rate and the amount of electricity your household uses. Making simple changes to everyday habits and choosing the right electricity plan can help you manage costs more comfortably.

Introduction

Most of us do not think too much about electricity rates until the monthly bill arrives and looks higher than expected. Maybe you have been using the air-conditioner more often. Maybe everyone has been home more frequently. Or perhaps your usage has stayed about the same, but the amount you are paying has still gone up.

That is where the electricity tariff comes in. An increase in the electricity tariff can affect how much you pay even when your usual routines have not changed much. In Singapore, these changes are often due to a combination of fluctuating global fuel prices and local energy needs

What is an electricity tariff?

In Singapore, the electricity tariff is the rate households pay for each unit of electricity consumed, usually measured in cents per kilowatt-hour (kWh). If your home is buying electricity from SP Group under the regulated tariff, this is the benchmark rate that determines the electricity portion of your monthly utility bill.

The electricity tariff is reviewed quarterly by SP Group in accordance with guidelines set by the Energy Market Authority (EMA). In other words, it is not a fixed price for the whole year. The rate can change every three months depending on the approved tariff for that quarter.

From 1 July to 30 September 2026, the regulated household electricity tariff is 34.78 cents per kWh, including GST. SP Group also announced that this represented a 17.0% increase from the previous quarter, which puts the regulated tariff at a record high. However, this does not mean that tariffs will keep rising indefinitely.

What Can Cause Electricity Tariffs to Rise?

1. Rising Global Fuel Prices

The biggest driver of increases in Singapore’s electricity tariff is usually the cost of natural gas. Singapore generates about 95% of its electricity using imported natural gas, so local electricity prices are closely linked to global gas markets.

When gas prices rise overseas, it becomes more expensive for power generation companies in Singapore to produce electricity. This can happen when global gas supply is disrupted, demand increases in other countries, or events such as geopolitical tensions and extreme weather affect energy markets.

Even if your household or business uses the same amount of electricity as before, higher imported fuel costs can still lead to a higher tariff in the following quarter.

2. The Cost of Generating and Delivering Electricity

Electricity tariffs are not made up of fuel costs alone. They also include the broader costs of generating electricity and delivering it safely and reliably to homes and businesses across Singapore.

These non-fuel costs include maintaining the power grid, transporting electricity through the network, reading meters, processing bills, and operating the wider electricity market. They also reflect the cost of maintaining a reliable electricity supply, including the infrastructure and systems needed to keep power flowing every day.

These costs usually do not change as sharply as global gas prices. However, they still form part of the overall tariff and may affect electricity prices over time as Singapore’s energy system is maintained, upgraded, and operated.

How Higher Electricity Tariffs Affect Consumers

When electricity tariffs increase, the most immediate effect is simple: your electricity bills become more expensive.

For Households

For households, this can mean higher monthly living expenses. Homes that use air-conditioning often, have multiple people working or studying from home, or rely on appliances such as dryers, ovens, and older refrigerators, may feel the impact more noticeably. A tariff increase of just a fraction of a cent per kWh may not seem significant at first, but over a full month of regular usage, it can still make a difference to the total bill.

For Businesses

Businesses may feel the impact differently. Higher electricity tariffs can raise day-to-day operating costs, which is particularly relevant for sectors that rely heavily on cooling, lighting, refrigeration, or machinery. Food and beverage outlets, retail spaces, logistics operators, manufacturers, and hotels may all see electricity costs make up a larger share of their overheads as tariffs climb.

Changes in Consumer Behaviour

Rising tariffs can also change consumer behaviour. Households may start paying closer attention to their monthly electricity usage, while businesses may look more seriously at efficiency measures, equipment upgrades, or fixed energy plans that offer greater pricing certainty. In that sense, higher tariffs affect not only bills but also the decisions people make about how they consume and manage electricity.

How to Better Manage Electricity Costs

While households and businesses cannot control global fuel prices or market-wide tariff movements, they can still take steps to keep electricity costs more manageable. A good place to start is by looking at how electricity is being used day to day, identifying areas of unnecessary consumption, and reviewing whether your current electricity plan still suits your needs.

1. Improve Everyday Energy Efficiency

One of the simplest ways to manage electricity costs is to reduce unnecessary usage. This does not mean making drastic lifestyle changes, but rather paying attention to small habits that add up over time.

For households, that may mean switching off appliances when they are not in use, using LED lighting, setting the air-conditioner at a more moderate temperature, or running full loads in the washing machine instead of smaller ones. Businesses can look at similar habits on a larger scale, such as reviewing cooling settings, switching off non-essential lighting after operating hours, and maintaining equipment to run more efficiently.

2. Monitor and Understand Your Electricity Usage

It is much easier to control electricity costs when you know where the usage is coming from. Looking at monthly bills, usage patterns, or smart meter data can help households and businesses spot areas of high consumption.

For example, a household may realise that air-conditioning accounts for a large share of its bill, or that an older appliance is using more power than expected. A business might find that certain equipment runs longer than necessary, or that electricity use spikes during specific operating hours. These insights can make cost-saving efforts more targeted and practical.

3. Compare Electricity Plans for Better Cost Predictability

Reviewing your electricity plan can be a practical way to manage an increase in electricity prices. While both households and businesses may benefit from greater price certainty, the type of plan that makes sense will depend on how electricity is used, how predictable monthly consumption is, and how much exposure to tariff or market fluctuations you are comfortable with.

For Households

Households may want to compare the regulated tariff against fixed-price plans offered by electricity retailers. The regulated tariff changes quarterly, so bills may rise or fall over time, while a fixed-price plan locks in a set rate for the contract period and can make monthly budgeting more predictable.

When comparing residential electricity plans, it helps to look at the contract period, whether there are early termination charges, and whether the pricing structure suits your household’s usual usage patterns.

For Businesses

For businesses, the focus is often less on convenience and more on cost control. This is where having access to a provider such as Flo residential electricity plans], which offers different pricing structures for businesses, can be helpful. Depending on your risk appetite and operating profile, you may consider:

Fixed-price plan: You pay the same electricity rate for the duration of your contract. This can make it easier to plan monthly expenses.
Pool plan: Your electricity rate changes with market prices. Your bill may be lower when prices fall, but it can also increase when market prices rise.
Hybrid plan: Part of your electricity rate is fixed, while the rest changes with market prices. This gives you some price certainty while keeping some flexibility.

It is also important to check how the business electricity plan is structured. For example, are certain charges bundled into the rate or passed through separately? Does the contract suit your operating hours, usage profile, and cash flow needs? These details can make a meaningful difference to long-term electricity costs.
