Following some important orders, more Wärtsilä energy storage systems have been installed in Singapore and South-East Asia. In particular, Wärtsilä supplied a 2.4 MW/2.4 MWh energy storage system (ESS) 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, a leading energy utilities company in Asia Pacific and it represents an important milestone in Singapore’s energy transition towards a low-carbon energy future, as it is indeed the first utility-scale ESS in Singapore.

Insights for performances under Singapore’s hot and humid environment

The ESS will participate in the wholesale electricity market to provide services necessary to mitigate intermittency caused by solar, as well as 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.

«This is an important step forward for Singapore’s energy system. We expect this first battery system in Singapore to enhance grid stability by providing the quick response and flexibility needed when integrating solar power into the grid. This project will also provide learnings for future ESS applications and pave the way for more solar power to generate more green energy in Singapore», said Frank Phuan, CEO and Executive Director of the Sunseap Group.

Wärtsilä awarded energy storage system order from South East Asia

Wärtsilä has also received a repeat energy storage system order totalling 90 MW/90 MWh from an existing South East Asian customer. The solution will provide much needed flexibility and reliable grid support and will allow the further integration of energy from renewable sources, such as solar and wind power.
