What is the Open Electricity Market (OEM)?

Geneco Open Electricity Market Singapore

OEM, or Open Electricity Market, gives households and corporate entities in Singapore the liberty to purchase electricity from a retailer of their choice. This provides consumers with more options and increased flexibility in picking a price plan that best suits their electricity needs.

Since April 2018, residents of Jurong can purchase electricity plans from private retailers, or continue receiving electricity from SP Group. From 1 November 2018, OEM will launch in areas with postal codes starting with 58 to 78. Thereafter it will be extended to all households across Singapore by zones progressively. About 1.4 million household and business accounts will have the option of buying electricity from a retailer at a price plan that best meets their needs. OEM gives consumers more choice and flexibility when buying electricity, while being provided with the same electricity supply through the national power grid.

What's in it for me?

An open electricity market means that you, as a consumer, get more power plan options when it comes to buying electricity. A bigger market will also lead to greater competition, which, in turn, brings about better electricity prices and more attractive plans for homes and businesses.


In short, you’ll get better choices and bigger savings.

Electricity explained

Here’s a handy guide to some common electricity terms. 

What is kWh?

kWh stands for kilowatt per hour, which is a basically a measurement for how much energy you’re consuming. 

What is SP Grid?

SP Grid is short for Singapore Power Grid, which is the system of interconnected power lines that transport electricity from generators to consumers. 

What is MSSL?

MSSL stands for Market Support Services Licensee, which in Singapore’s case is SP Services Ltd. They provide services such as the settlement of bills, meter reading, data management, and customer transfer services. 

What is an AMI meter?

Advanced Metering Infrastructure (AMI) meters allow electricity consumption to be measured at half-hourly intervals, resulting in more accurate readings. 

What is TLF?

Transmission Loss Factor (TLF) accounts for the energy that’s lost as electricity passes through the system to get to your house. Normally, TLF charges are passed through to the consumer. However, at Geneco, we bear the charges, so that you don’t have to.
