Swiss engineering firm ABB has been selected to supply backup power systems for a large-scale dual-mode desalination plant in Singapore.
ABB said the contract for the project, awarded by Keppel Infrastructure subsidiary Keppel Seghers, includes supplying complete electrical, instrumentation and automation and control systems for Singapore’s fourth desalination facility— the Keppel Marina East Desalination Plant.
The scope of supply includes AC and DC uninterruptible power supply and emergency diesel generator, 66kV gas-insulated switchgears, power and distribution transformers, medium- and low-voltage switchgears and drives, control system, remote terminal units, field instruments and analytical systems.
For this plant, ABB said it will design, engineer, manufacture, install, test and commission the complete plant electrification, instrumentation and water analysers, automation and control system.
The design-build-own-operate project initiated by Singapore’s national water agency will produce approximately 30 million gallons of fresh drinking water a day, which ABB said is “enough to fill about 55 Olympic-sized swimming pools” when finished by 2020.
According to ABB, Singapore’s water comes from four sources— reservoir, imports from Malaysia, “ultra-clean high-grade reclaimed water” branded NEWater in Singapore and desalinated water. “Desalination therefore plays a strategic role in Singapore’s vision for a diversified and sustainable supply of water, and is expected to meet up to 30% of water demand by 2060,” ABB said.
As a dual-mode facility, ABB said the new desalination plant will be able to treat either fresh or seawater, depending on wet or dry weather conditions, “reducing plant energy usage when freshwater is abundant”.
