This initiative, implemented progressively since 2018, allows consumers in Singapore to choose their electricity retailer from a pool of licensed retailers. The liberalization of the electricity market aims to promote effective competition, lower prices, and provide consumers with more choices in terms of price plans and services.

The Singapore energy market is overseen by the Energy Market Authority, which regulates and ensures the reliability, security, and efficiency of the market operations. EMA’s role includes maintaining the integrity of the wholesale electricity market, facilitating demand and supply balance, and promoting sustainability in the energy sector.

The Singapore energy market is robust and continues to evolve to meet the increasing energy demands of the nation. With a focus on competition, reliability, and sustainability, the market offers consumers the flexibility to choose their electricity provider and benefit from lower prices and innovative energy solutions.
