Energy Storage Systems (ESS) is an essential technology to enhance grid reliability in Singapore. By the end of 2022, Singapore will have over 200 megawatt (MW)/200 megawatt-hour (MWh) of ESS deployed, which could store sufficient energy to power the daily electricity needs of over 16,700 4-room HDB households1 in a single discharge.
2. The Energy Market Authority (EMA) appointed Sembcorp Industries to build, own and operate 200MW/200MWh of ESS to enhance the resilience of our energy supply and power grid in June this year. The ESS is currently being installed across two sites on Jurong Island and spans two hectares of land. When operational in November 2022, it will be the largest ESS deployment in South-East Asia, and one of the fastest of its size to be deployed.
3. ESS function as large-scale batteries to store energy and dispense it at other times when needed to maintain grid reliability. The fast-response nature of ESS also allows it to actively manage mismatches in electricity supply and demand and perform regulation services to address second-to-second fluctuations in the power grid, which can mitigate the impact of solar intermittency. In view of the ongoing volatility in the global energy market, it can be used to store energy to provide reserves to the power grid when needed, freeing up power generation plants to generate more electricity to meet demand.
4. The ESS will use lithium iron phosphate (LFP) batteries. This technology is a proven, safe and high-performing method of renewable energy storage widely used worldwide. Their fast-response time, high energy density and high round trip efficiency, which measures the amount of energy stored that can be retrieved later, make them suitable for the purpose of maintaining grid stability.
5. Along with our partners and other government agencies, EMA is also
developing policies, regulations and standards to support and guide the deployment
of ESS in Singapore. This includes local standards and guidelines on safety
considerations for deploying and maintaining ESS under local operating conditions.
