BATTERY ENERGY STORAGE SYSTEM FOR LARGE DATA CENTRE

Recently, we performed a grid connection study for one of our large data center clients who was looking to install a Battery Energy Storage System (BESS) on their site.

locations in Ireland

THE CHALLENGE

The goal of the study was to examine whether the data center would still be grid compliant after the addition of the proposed BESS. Due to their size this site is a large consumer of power, any changes to their mode of operation sparks a keen interest from the local utility provider to ensure it does not adversely affect the local grid.

HOW WE HELPED

Using the DigSilent modelling tool we evaluated the various modes of operation made possible by the BESS and how the power supply reacted to different operational scenarios as set out by the utility. Frequency response, reactive and active power response and fault ride through capability were all evaluated. 

THE RESULT

We concluded that the addition of a BESS at this particular site would not impact the clients ability to comply with grid requirements. The utility provider was satisfied with the results and the client can now confidently proceed with their plans to install a BESS. 

THE CLIENT

The client was a large data centre based in Belgium who consumes a high amount of power from the local grid.

“Battery Energy Storage Systems are becoming more prominent in the energy mix. Their versatility allows the user to have more control over when and how energy is stored or dispatched. With an increased focus on renewables, the ability to store this green energy when it's at its peak ensures your energy system can continue to operate at peak performance and reduce energy costs during fluctuations in service. As the technology improves and becomes more widely used it's important, as with any energy generating equipment, that it adheres to the energy provider requirements.”
