What is Tuaspring?
Tuaspring Desalination Plant (Tuas II), the biggest seawater reverse osmosis desalination plant in Asia, integrates a combined-cycle power plant (CCPP), which was connected to the national grid in August 2015.
How much energy is needed for desalination?
The theoretical absolute minimum amount of energy required by natural osmosis to desalinate average seawater is approximately 1 kilowatt-hour per cubic meter (kwh/m3) of water produced, or 3.8 kilowatt-hours per thousand gallons (kwh/kgal).
How Hyflux was brought down by its ambition?
Tuaspring was never meant to be Hyflux’s project. The tender specified that there would be no pass-through on the cost of power for the project. That is to say, the owner of the plant would not be compensated with higher water tariffs if electricity tariffs rose.
What is the difference between NEWater and desalinated water?
Desalinated water, which currently meets up to 30 per cent of water demand and will meet 30 per cent of future demand in 2060, is the most energy-intensive water source. NEWater, on the other hand, currently makes up 40 per cent of water demand, and meet up to 55 per cent of future demand in 2060.
How much does desalination cost?
Desalinated water typically costs about $2,000 an acre foot — roughly the amount of water a family of five uses in a year. The cost is about double that of water obtained from building a new reservoir or recycling wastewater, according to a 2013 study from the state Department of Water Resources.
How much does desalination cost per year?
How much does it cost to desalinate 1 cubic Metre of water?
The unit costs for all processes have fallen considerably over the years. This study suggests that a cost of $1/m3 for seawater desalination and $0.6/m3 for brackish water would be feasible today. The costs will continue to decline in the future as technology progresses.
How did Hyflux fall?
We now know that the collapse in electricity price was the direct result of the vesting contracts given to the other gencos in return for their support to sign long term take-or-pay gas supply contracts from the LNG terminal, itself another national project.
Is Hyflux still operating?
Hyflux will finally go into liquidation after the High Court ruled in favour of winding up the troubled water treatment firm. However, observers warn that retail investors may not get back the money they have poured in.
What is NEWater used for?
As it is ultra-clean, NEWater is used mainly for industrial and air-con cooling purposes at wafer fabrication plants, industrial estates and commercial buildings. The biggest users of NEWater are wafer fabrication plants, which require water quality that is even more stringent than water for drinking.
Is NEWater a toilet?
NEWater is recycled from treated sewage (‘used water’) and produced using a rigorous 3-step purification process involving ultrafiltration/microfiltration, reverse osmosis (RO) and ultraviolet (UV) disinfection.
What is the market share of the Tuaspring power plant in Singapore?
At the end of 1Q2019, the Tuaspring power plant’s market share of the electricity generation capacity in Singapore was 2.9%. YTL Power Seraya’s market share was 22.7%.
What does Tuaspring Desalination Plant stand for?
Tuaspring Desalination Plant (Tuas II), the biggest seawater reverse osmosis desalination plant in Asia, integrates a combined-cycle power plant (CCPP), which was connected to the national grid in August 2015. The desalination plant is designed for a capacity of 318,500m³ (70 million gallons) a day,…
What is tutuaspring’s EV/mw?
Tuaspring is a 396MW combined cycle gas power plant. In arriving at our EV/MW of US$1.3mil, we have assumed that the power plant has borrowings of S$420mil. This is based on a debt-to-equity ratio of 80/20.
Who bid for Hyflux’s Tuaspring project?
SEMBCORP Industries Ltd was the only party that submitted a final bid for beleaguered Hyflux Ltd’s Tuaspring project, which includes South-east Asia’s biggest desalination plant, people with knowledge of the matter said.
