Singapore’s electricity industry is structured to facilitate competitive wholesale and retail markets. This was achieved by separating the ownership of the contestable parts of the industry from those with characteristics of a natural monopoly. To promote the entry of new participants, licenses have also been granted to parties that intend to establish new businesses to participate as electricity generators or retailers. Current market participants are listed below.
Generation Licensees generate electricity for injection into the power grid. They offer to generate various quantities of electricity at their associated prices. All offers are then pooled in the wholesale market to match the demand for electricity.
Active generators are: Sembcorp Cogen Pte Ltd, National Environment Agency, Keppel Merlimau Cogen Pte Ltd, Senoko Waste-To-Energy Pte Ltd (in its capacity as Trustee of Senoko Trust),Tuas Power Generation Pte Ltd, Senoko Energy Pte Ltd, Shell Singapore Pte Ltd, Keppel Seghers Tuas Waste-To-Energy Plant Pte Ltd(in its capacity as Trustee of Tuas DBOO Trust), ExxonMobil Asia Pacific Pte Ltd, PacificLight Power Pte Ltd, YTL PowerSeraya Pte Ltd, TP Utilities Pte Ltd, Singapore Refining Company Pte Ltd, TuasOne Pte Ltd, Sembcorp Floating Solar Singapore Pte Ltd, Sembcorp Solar Singapore Pte Ltd and Taser Power Pte Ltd.
Interruptible loads are contestable consumers of electricity that participate in the wholesale market and allow their supply of electricity to be interrupted in the event of a system disturbance in exchange for reserve payments.

An MSSL is authorised to provide market support services. Such services include consumer registration and transfer, meter reading and meter data management, retail settlements and billing for contestable consumers. SP Services Ltd is the only MSSL.
