Singapore has marked a significant milestone in its journey towards sustainable energy by launching its first utility-scale Energy Storage System (ESS). Developed in collaboration between the Energy Market Authority (EMA) and SP Group, this innovative project aims to enhance the stability and efficiency of Singapore’s electricity grid while facilitating greater integration of renewable energy sources, particularly solar power.
Project Overview
The ESS test-bed features two installations strategically located in Singapore’s northern and northeastern regions, offering a combined energy storage capacity of 4.4 MWh. This capacity can power approximately 330 four-room HDB flats for an entire day. Employing advanced redox flow and lithium-ion battery technologies, the test-bed will provide valuable data on performance and safety under Singapore’s specific climate conditions.
The project goals include:
- Evaluating ESS technologies in tropical climates.
- Developing technical standards for future ESS deployments.
- Supporting increased solar energy utilization by addressing intermittent supply challenges.
Industry Collaboration
The ESS test-bed has been funded with approximately S$17.8 million awarded to Singapore-led consortiums CW Group and Red Dot Power. Key technology partners include global leaders like Wärtsilä, providing their GridSolv Max and GEMS energy management systems, and Sunseap Energy Ventures, responsible for operational deployment.
Advancing Renewable Energy Integration
Due to limited renewable resources, solar power remains Singapore’s primary renewable energy solution. However, the intermittent nature of solar power presents grid management challenges. The ESS system directly addresses this by:
- Quickly responding to grid demand fluctuations.
- Enhancing grid reliability and resilience.
- Helping achieve Singapore’s goal of 1 GWp solar capacity beyond 2020.
Insights from Industry Leaders
EMA Chief Executive, Mr. Ng Wai Choong, emphasized the significance of the ESS:
“Insights from this test-bed would be useful for Singapore to learn how storage could enhance the stability of our grid, provide quick response capacity, and improve operational flexibility.”
SP Group CEO, Mr. Wong Kim Yin, highlighted the cost-saving potential:
“SP Group is committed to helping Singapore save energy and cost. This collaboration with EMA assesses how storage can lead to greater efficiency.”

Summary
Singapore’s launch of its first utility-scale Energy Storage System represents a landmark step towards sustainability and improved energy resilience. Developed by the Energy Market Authority (EMA) and SP Group, this project features two test-bed installations with a total storage capacity of 4.4 MWh, sufficient to power hundreds of homes for a day. Using both redox flow and lithium-ion battery technologies, the initiative aims to evaluate the performance and safety of ESS under Singapore’s tropical conditions.
The project is part of broader efforts to facilitate renewable energy integration, particularly solar energy, by mitigating intermittency issues that can destabilize the grid. Approximately S$17.8 million has been allocated to local consortiums CW Group and Red Dot Power, which are supported by international technology providers such as Wärtsilä and Sunseap Energy Ventures.
Leaders from EMA and SP Group have emphasized the strategic importance of the ESS in ensuring grid stability, responsiveness, and operational efficiency. The project is poised to provide critical insights into energy storage technologies, setting the stage for broader adoption of renewables in Singapore and contributing significantly to its ambitious solar deployment goals. This pioneering step underscores Singapore’s commitment to becoming a regional leader in sustainable energy solutions.
