DNV ensured the completeness and proper execution of mandatory Site Execution Test (SAT) activities, an important milestone on the way to launch the 285 megawatt hour (MWh) storage system into commercial operation, marking the completion of the plant qualification process. The company’s role in the ESS project covered witnessing the mandated tests, processing the raw data, and approving the final commissioning reports from two different original equipment manufacturers, Huawei and Envision.
The project went online as planned in December 2022, as scheduled by Sembcorp. Commissioning the project took only six months compared to the industry average of 15 to 18 months for similar capacity installations.
“Despite the very tight timeline set, adhering to the schedule was critical in this project” said Dr. George Garabandic, DNV project manager and Energy Storage Systems Lead, APAC. “This required us to adopt an agile way of working that involved a regular review and strict adherence to priorities.”
The 285 MWh Sembcorp ESS on Jurong Island, the largest in Southeast Asia, was commissioned in six months, making it the fastest deployment of its size in the world, according to Chua Kia, Head, Project Management Office, Singapore & Southeast Asia, Sembcorp Industries.
In 2019, Singapore’s Energy Market Authority (EMA) set a deployment target of at least 200 MWh of energy storage system capacity beyond 2025, to complement Singapore’s efforts in maximising solar adoption. The fast response nature of ESS is essential in mitigating solar intermittency caused by changing weather conditions in Singapore’s tropical climate. It would also enhance Singapore’s power grid stability and resilience by managing mismatches between electricity demand and supply.
