Data centers are an integral part of maintaining our digital world, supporting everything from cloud computing to artificial intelligence. However, they come with a substantial environmental footprint due to the amount of energy required to power and cool these facilities. As more and more data centers are constructed to meet soaring demands globally, engineers must find sustainable energy solutions to futureproof these essential buildings such as Battery Energy Storage Systems (BESS).

Battery Energy Storage Systems (BESS)

BESS are advanced systems designed to store electrical energy in batteries for later use. Data centers rely on uninterruptible power supplies (UPS) and diesel generators to manage power interruptions, however, these methods often involve significant carbon emissions and operational costs. BESS offers a more sustainable alternative by efficiently storing energy during periods of low demand or when renewable energy generation is at its peak, and then releasing it during high-demand periods or power outages.​

Sustainability

The global surge in electricity consumption has highlighted the environmental impact of data centers. According to the International Energy Agency (IEA), power demand is set to grow nearly 4% annually through 2027. This escalating energy demand prioritises the need for data centers to adopt sustainable practices to decrease their carbon footprint and secure long-term operational viability.​

Advantages of Implementing BESS in data centers

1. Enhanced Energy Efficiency: By utilising stored energy during peak demand periods, data centers can reduce their reliance on the grid, leading to more efficient energy use and lower operational costs.​
   
2. Integration with Renewable Energy Sources: BESS facilitates the use of renewable energy into data centre operations by storing excess energy generated from sources like solar or wind. This stored energy can then be used when renewable generation is low, for a more consistent and sustainable power supply.​
   
3. Grid Stabilisation and Support: Data centers with BESS can provide ancillary services to the grid, such as frequency regulation and load balancing. This supports grid stability and provides the possibility to make revenue through participation in energy markets.​
   
4. Reduction in Carbon Emissions: By decreasing dependence on fossil-fuel-based backup generators and optimising energy consumption, BESS can significantly reduce greenhouse gas emissions associated with data centre operations.​

Challenges and Considerations

However, there are safety concerns remaining with regard to battery storage and potential fire hazards, requiring strict prevention and management strategies to meet regulations. Additionally, the initial capital expenditure for BESS can be significant compared to traditional methods despite their long-term savings and environmental advantages.
