Open Electricity Market (OEM) Singapore: Complete 2019 Guide | SingSaver

Still considering if you should switch electricity retailers or aren’t sure which to go for? Here’s your complete guide to the Open Electricity Market and its various plans.

Prices and promotions are subject to change at any time.

What is Open Electricity Market?

Open Electricity Market (OEM) is an initiative by the Energy Market Authority (EMA) to liberalise and open the electricity market to new players. For the end consumer, that means you enjoy more options and flexibility when buying electricity, with the end goal of lowering your monthly electricity bills.

From 1 November 2018 to 1 May 2019, the OEM was gradually rolled out nationwide to all consumers, mainly households, by zones. All households can now switch to their preferred OEM retailer and choose a price plan that best meets their needs. Alternatively, they can choose to stay with the incumbent provider, SP Group.

Currently, there are nine OEM retailers offering competitive pricing and promotions that help lower your monthly electricity bills.

Which is the best electricity retailer in Singapore?

Before choosing an OEM retailer, you need to understand how quarterly tariff prices are set by SP Power, and what factors contribute to price fluctuations. Then you can pick the plan that best suits how your household consumes electricity. There is also no pressure to switch to a new retailer if you’re undecided or are happy with the incumbent provider, SP Group.

There are three main types of OEM plans:

The “best” electricity retailer really depends on your household’s electricity consumption. For example, if your household consumes electricity mostly during non-peak hours, you can take advantage of Peak/Off-Peak Price Plans. If your consumption is lower than the national average, check out the Discount Off Regulated Tariff Plan.

When choosing your electricity retailer, you don’t always have to go for the cheapest option. Consider other factors such as credit card rebates, referral and promo codes, and each retailer’s unique value proposition.

How are electricity tariffs calculated every quarter?

The tariff set by SP Services is reviewed each quarter and regulated by the Energy Market Authority (EMA) to reflect the actual cost of electricity. This tariff comprises two key components: fuel cost and non-fuel cost.

Fuel costs are tied to natural gas prices, which are indexed to oil prices by commercial contracts. These prices change depending on global market conditions. About 95% of Singapore’s electricity is generated by imported natural gas, which means that the price of electricity is closely tied to global conditions and oil prices.

Non-fuel costs are the cost of generating and delivering electricity to homes, such as:

  • Power Generation Cost: the manpower and maintenance costs of running the power stations
  • Grid Charge: the cost of transporting electricity through the power grid
  • Market Support Services (MSS) Fee: the costs of billing and meter readings
  • Power System Operation and Market Administration Fees: costs related to operating the power system and administering the wholesale electricity market

The current tariff price is 29.90 cents per kWh (incl. GST) (1 April – 31 June 2022)

What should I watch out for when choosing an electricity retailer? 

Be sure to read the fine print before committing to any plan. Beyond the competitive prices advertised, ask for a Fact Sheet and Consumer Advisory so that you can check on:

  • Paper bill fee
  • Security deposit
  • Administrative fees
  • AMI meter installation fees
  • Auto-renewal clauses
  • Carbon tax
  • Early termination charges
  • Late payment fees
  • Transmission loss factor
  • Eligibility for using U-Save GST vouchers

You can also ask for any partner benefits when signing up for a particular retailer.

For example, Keppel Electric is offering an exclusive switch promo with a card rebate of up to S$30. Meanwhile, Senoko Energy is offering up to S$60 bill rebate on any 24-month plan with the promo code ‘SMART60’.

How do I switch electricity providers?

Step 1: Check out and compare price plans that OEM retailers are offering using the super handy Price Comparison Tool.

Step 2: Contact your preferred OEM retailer and ask for more information on the price plan you’re interested in. Be sure to ask for a Fact Sheet and Consumer Advisory.

Step 3: Once you’ve decided on a price plan, sign up with your preferred OEM retailer who will work directly with SP Group to initiate the switch.

Will my electricity supply be disrupted during the switch? 

Your electricity supply will not be disrupted if and when you decide to switch OEM retailer. Regardless of who you buy your electricity from, your electricity supply will stay the same because the SP Group operates the national power grid and delivers electricity to consumers.

Will I incur extra fees for switching electricity retailers?

If and when you decide to switch from the SP Group to your preferred OEM retailer, you will not incur any extra fees nor additional charges.

What happens if I change my mind after switching energy supplier? 

In case you change your mind after switching from the SP Group to your current OEM retailer, your current OEM retailer will co-ordinate with the SP Group to make the switch. But take note of any terms and conditions for early termination charges on lock-in contracts when you sign up to a new OEM retailer.

How will I be billed for my electricity if I switch retailer?

Your billing arrangement depends on your chosen electricity retailer. If the retailer bills you directly, you should receive 2 utility bills every month: 1 for electricity, and 1 for water, gas, and refuse.

If your retailer bills you through SP Group, nothing much will change and you will get 1 consolidated bill covering electricity, water, gas, and refuse charges.

If you’re unsure, check with your retailer on their billing arrangement.

Here’s an example of a monthly statement from PUB (based on a two-adult household). You can see electricity and water services are consolidated into one statement, so if you switch retailers, the electricity services component will come as a separate statement.

Best Fixed Price Plans in Singapore 2022

A Fixed Price Plan offers a flat rate per kilowatt hour (kWh) for a designated lock-in or contract period – this flat rate can change once your contract is over. This is why some retailers are advertising longer lock-in periods as a way for you to ‘book’ lower promo rates.

During the lock-in period, your household is not subject to quarterly fluctuations that may be higher or lower than regulated tariff over time.

If you prefer certainty over price fluctuations in your monthly bill, Fixed Price Plans may be the best choice for you.

However, there are very limited plans in the market currently, with the only one being a 12-month contract.

Best Peak and Off-Peak Plans in Singapore 2022

Peak and Off-Peak Plans are non-standard price plans that allow consumers to pay their preferred price for electricity usage depending on the time of day. They can vary between the fixed-rice or discount-off-regulated-tariff models, but the main beneficiaries are households that consume most of their electricity during off-peak hours like the evenings, early morning hours or weekends. However, there are no available off-peak plans currently.

Bottom Line

It may seem obvious to make a dash for the cheapest OEM plan in the market, but hold your horses. First, consider other factors like your household’s electricity consumption patterns.

Also check for additional charges as mentioned above, like (hidden) administrative fees, auto-renewal clauses, early termination fees, and carbon taxes.
