A 2.4 MW utility-scale energy storage system (ESS) is now online. The first in Singapore, the ESS was supplied by Wärtsilä for Sunseap Energy Ventures of Singapore under an engineering, procurement and construction (EPC) contract. The ESS facility is a test-bed supported by Singapore’s Energy Market Authority (EMA) and SP Group, an energy utilities company in Asia Pacific. The project moves Singapore towards its energy transition to a low-carbon future, Wärtsilä said in a press release.

The ESS will participate in the wholesale electricity market to provide services necessary to mitigate intermittency caused by solar and reduce peak demand. The utility-scale energy storage system will also provide insights into ESS’ performance under Singapore’s hot and humid environment and will aid in establishing technical guidelines for such deployments.


The ESS incorporates Wärtsilä’s GEMS advanced energy management platform, as well as the company’s GridSolv Max solution, a standardized energy storage technology designed for safety with core storage hardware assets, including batteries and inverters.

Singapore targets to have at least 2 GWp of solar deployment by 2030, and an energy storage deployment of 200 MW beyond 2025.
