What are TES Water Tanks?
Thermal Energy Storage (TES) systems are at the forefront of modern energy management. These systems store energy as chilled water or ice, allowing data centres to manage electricity consumption more efficiently. By storing energy during off-peak hours, when electricity is cheaper and demand is lower, TES systems reduce the strain on power grids during peak periods.
One key advantage of TES tanks is their role during power shutdowns. When a power outage occurs, it typically takes 5-10 minutes to restart power generators. During this time, TES tanks provide the necessary cooling to servers, preventing overheating and potential damage.
TES systems operate on a simple yet effective principle. During times of low energy demand, chillers produce chilled water or ice, which is stored in insulated tanks. When energy demand spikes, especially during peak hours, the stored chilled water or ice is used for cooling instead of running energy-intensive chillers. This process significantly reduces overall energy consumption and operational costs.
Data centres experience high energy demands due to the constant operation of servers and cooling systems, leading to substantial electricity bills and environmental impact. By integrating the TES water tank, data centres can shift a considerable portion of their cooling energy consumption to off-peak periods, optimizing energy usage and reducing peak electricity demand charges. TES systems enhance energy efficiency and sustainability in data centre operations.
Importance of Using TES Water Tanks in Data Centers
TES water tanks are crucial for maintaining optimal temperatures in data centres. Servers produce significant heat, and it's vital to keep the server rooms cool to prevent overheating and potential damage. TES tanks store chilled water that can be used during power outages, ensuring continuous cooling even when the electricity supply is interrupted.
In case of a power shutdown, there is often a delay of 5-10 minutes before backup generators can restore power. During this time, TES tanks provide the necessary cooling to prevent server rooms from heating up, avoiding the risk of short circuits and equipment damage. By enhancing energy efficiency, providing reliable backup cooling, and supporting scalability, TES water tanks help data centres operate smoothly and sustainably.
Incorporating TES water tanks is a strategic move for data centres, offering significant benefits in cost savings, energy efficiency, reliability, and environmental impact. As data centres continue to expand, TES water tanks will be essential for meeting modern data processing demands while promoting sustainability.

1. Peak Demand Issues
Managing energy in data centres is a complex task, especially during peak demand periods. The use of TES water tanks can address some of these challenges effectively. Data centres operate 24/7, requiring continuous cooling to prevent the overheating of servers. During peak hours, the demand for energy surges, straining power grids and increasing electricity costs.
Additionally, the financial impact of outages has become more severe. The Uptime Institute reports that the percentage of outages costing over $100,000 has increased to 60%, up from 39% in 2019. Moreover, the proportion of outages costing over $1 million has grown from 11% to 15%. These statistics underscore the necessity of solutions that reduce downtime and financial risks, emphasising the critical need for reliable energy management strategies to avoid such costly disruptions.
2. Cost Implications
High energy demands during peak hours lead to several problems. Firstly, the cost implications are significant. Electricity prices are higher during peak periods due to increased demand. Data centres, consuming vast amounts of power, face steep energy bills. These costs can be a substantial part of the operational budget, affecting overall profitability.
3. Environmental Impact
Traditional cooling methods used in data centres have a considerable environmental impact. Most data centres rely on air conditioning systems that run continuously to keep the servers cool. These systems consume a lot of electricity and often use refrigerants that contribute to greenhouse gas emissions. The environmental footprint of these cooling methods is substantial, contributing to global warming and climate change.
4. Strain on Power Grids
The strain on power grids during peak hours is another critical challenge. As data centres draw large amounts of power, they add pressure on the local power infrastructure. This can lead to power outages or reduced reliability of electricity supply, affecting not only the data centres but also other consumers in the area.
The challenges in energy management for data centres are multifaceted. High energy costs, environmental impact, and the strain on power grids are significant issues that need addressing. Integrating TES water tank applications offers a promising solution to these challenges by optimising energy use and reducing reliance on traditional cooling methods.
The Role of TES in Data Centers
In the quest for more efficient energy management, cylindrical TES water tanks stand out as a transformative solution for data centers. These systems help shift energy consumption to off-peak hours, offering significant efficiency gains.
1. Efficiency Gains
TES water tanks play a crucial role in enhancing the efficiency of data centres. By shifting energy consumption to off-peak hours, TES systems help data centres manage their energy use more effectively. This approach not only reduces operational costs but also minimises the environmental impact.
2. Shifting Energy Consumption
TES systems store energy in the form of chilled water or ice during off-peak hours when electricity demand is lower and costs are cheaper. During peak hours, when electricity demand is high, the stored energy is used to cool the data centre. This method reduces the need for running energy-intensive cooling systems during peak periods, thus lowering overall energy consumption.
3. Cost Savings
The ability to shift energy consumption to off-peak hours translates into significant cost savings for data centres. Electricity prices are generally lower during off-peak times, so using stored energy during peak periods helps data centres avoid high electricity costs. Over time, these savings can be substantial, improving the overall profitability of data centres.
4. Reduced Carbon Footprint
Using TES water tanks also contributes to a reduced carbon footprint. Traditional cooling systems consume a large amount of electricity and often rely on refrigerants that are harmful to the environment. By reducing reliance on these systems, TES helps lower greenhouse gas emissions. Additionally, by easing the strain on power grids during peak hours, TES systems support a more sustainable energy infrastructure.
TES water tanks are vital for achieving efficiency gains in data centres. By shifting energy consumption to off-peak hours, data centres can save on operational costs and reduce their environmental impact.
Key Consideration for TES Water Tanks Application in Data Centres
Implementing TES water tanks in data centres involves several critical steps. This section provides a detailed look at how these tanks are designed and integrated into data centre infrastructure.
1. Design and Implementation
TES water tanks offer a strategic solution to improve energy efficiency in data centres. Their successful integration requires careful consideration of several key factors.
2. Capacity
The first step in integrating a TES water tank is determining the appropriate capacity. The tank must store enough chilled water or ice to meet peak-hour cooling needs. Engineers calculate the required capacity based on the size of the data centre, the number of servers, and the expected peak energy demand. Accurate capacity planning ensures the TES system can provide adequate cooling without overburdening the existing infrastructure.
3. Placement
The placement of the TES water tank is crucial for efficient operation. Ideally, the tank should be located near the data centre's cooling systems to minimise the distance the chilled water or ice needs to travel. This reduces energy loss and enhances efficiency. The tank should also be placed in an accessible area for maintenance but positioned so that it does not interfere with data centre operations. Structural support is essential since the tank will be heavy when filled.
4. Tank Type
It is important to use cylindrical tanks instead of panel tanks for TES applications in data centres. Panel tanks are unsuitable for data centres as they are primarily used in manufacturing industries for applications that require maintaining water temperature over long periods, even in extreme outside temperatures. Cylindrical tanks are better suited for TES applications in data centres due to their efficiency in storing and distributing chilled water or ice for cooling purposes.
5. Maintenance
Regular maintenance is vital for the long-term performance of the TES water tank. Inspections should be conducted to check for leaks, corrosion, and other issues. The tank and associated piping need periodic cleaning to prevent sediment buildup and ensure efficient heat exchange. Following a strict maintenance schedule extends the lifespan of the TES system and maintains its efficiency.
Integrating TES water tanks into data centres involves meticulous planning regarding capacity, placement, and maintenance. By addressing these factors, data centres can effectively implement TES systems to enhance energy efficiency and reduce operational costs.
