Singapore is updating its energy plans as it aims to reduce emissions and ensure energy security. The country plans to achieve net-zero emissions by 2050 and reduce its greenhouse gas emissions to between 45 and 50 million tonnes by 2035.
Today, natural gas powers 95% of Singapore’s electricity. The Energy Market Authority (EMA) said natural gas will continue to play a main role as the country adds low-carbon solutions.
Singapore is increasing its solar power capacity. The target is 2 gigawatt-peak by 2030. As of now, the country has already reached 1.5 gigawatt peak. This expansion is happening on rooftops and other built-up areas due to limited land. Still, solar energy is expected to cover only about 10% of electricity needs.
To make up for the land shortage, Singapore plans to import 6 gigawatts of low-carbon electricity by 2035. This will involve partnerships with nearby countries and cross-border electricity trade.
Other technologies are also being studied. These include hydrogen, advanced nuclear energy, and carbon capture systems. The EMA is keeping multiple options open to maintain a stable supply while shifting to cleaner sources.
To improve grid reliability, Singapore is testing battery energy storage systems. These large-scale batteries store electricity and release it quickly when needed. They help balance supply and demand during high-usage periods.
The country is also testing demand response programmes. These allow large energy users to lower their electricity use when demand is high. In return, they receive financial rewards.
In addition, there are several smaller, lesser-known initiatives underway. One example is a pilot project in western Singapore, where small-scale battery systems are being used to store excess solar power from industrial rooftops. These systems are typically between 100 kilowatt-hours and 500 kilowatt-hours.
Another one involves solar-powered electric vehicle charging points in urban carparks. The trial includes around 20 charging stations linked to rooftop solar panels with combined capacity of 200 kilowatts.
Singapore is also working with industry to test microgrids in offshore islands like Pulau Ubin, where solar, batteries, and diesel systems are combined.
