DNV has acted as the advisor for the commissioning of a large energy storage system on Singapore’s Jurong Island.
Sembcorp, the developer, enlisted DNV to ensure “completeness and proper execution” of mandatory Site Execution Test (SAT) activities, required ahead of commercialising the 285 megawatt hour (MWh) energy storage system.
DNV’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.
“Despite the very tight timeline set, adhering to the schedule was critical in this project. This required us to adopt an agile way of working that involved a regular review and strict adherence to priorities,” said George Garabandic, DNV project manager and Energy Storage Systems Lead, APAC.
In 2019, Singapore’s Energy Market Authority (EMA) set a deployment target of at least 200MWh of energy storage system capacity beyond 2025, to complement Singapore’s efforts in maximising solar adoption.
Sembcorp’s energy storage system – with a maximum capacity of 285MWh connected to the grid – marks the achievement of Singapore’s energy storage target ahead of time.
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.
