Wärtsilä To Build Energy Storage System For Singapore's Energy Market Authority And SP Group

Singapore ESS

The technology group Wärtsilä announced recently that CW Group has awarded it the provision of a 2.4 MW/2.4MWh energy storage system (ESS) test bed for Singapore's Energy Market Authority (EMA), a statutory board under the Ministry of Trade and Industry of Singapore and SP Group, a leading energy utility company in Asia Pacific. CW Group has been contracted by EMA and SP Group to implement this project.

The Wärtsilä solution will incorporate GEMS software from Greensmith Energy, a Wärtsilä company. This test bed will be Singapore's first utility-scale ESS, and the first such project in Asia for Wärtsilä / Greensmith. The plant is expected to be fully operational during the latter part of 2018.

Energy storage capacity will support Singapore's use of solar power by providing energy reserves and reducing peak demand. It will also assist EMA and SP Group to evaluate the performance of ESS technologies in the country's hot and humid climate, its impact on the electricity grid, and to establish future guidelines for ESS deployments.

Commenting on the project, Mr. Ng Wai Choong, CEO of EMA said; "Insights from this test bed will be useful for Singapore to learn how storage could enhance the stability of the grid, provide quick response capacity, and improve operational flexibility. We are also exploring how to couple energy storage with solar forecasting capabilities to enable greater deployment of solar in Singapore." Singapore aims to have 1 GW of its electricity from solar power by 2020, thereby significantly reducing the country's environmental foot print.

"As our first major energy storage deployment in Asia, the project represents a clear endorsement of our advanced technology and software, proven in over 6 countries, along with turnkey (EPC) capabilities provided by Wärtsilä / Greensmith in Singapore and Asia at-large. Energy storage is rapidly becoming a key issue for the global energy markets, and our solutions provide grid stability while enabling the integration of large scale deployments of solar and other renewable resources" said Andrew Tang, Senior Vice President, Greensmith Energy - a Wärtsilä Company.

Wärtsilä closed the acquisition of Greensmith Energy Management Systems Inc in July 2017. Greensmith is a leading energy storage integrator with over 150MW deployed in North America. Greensmith provides a full range of solutions including the turnkey delivery of storage systems complete with software controls to maximize returns for system owners/operators.
