Why do battery energy storage systems need grounding and bonding?
For grid-scale battery energy storage systems (BESS), grounding and bonding is essential for safety and performance. The goal of grounding and bonding is to achieve customer-targeted resistance levels. These low resistance levels allow fault currents to easily discharge into the ground, protecting people, equipment and the BESS itself.
What happens if a grounding system fails?
These low resistance levels allow fault currents to easily discharge into the ground, protecting people, equipment and the BESS itself. The consequences of a failed or insufficient grounding system can be severe – thermal runaway leading to fires, system downtime, component failures, reduced efficiency and other safety hazards.
How long does a grounding system last?
High-quality, value-engineered grounding systems are key to meeting the desired BESS infrastructure service life of at least 25 years. Other solutions may meet these requirements initially but will degrade over time. nVent provides tested solutions that will deliver long-term consistent results.
What is a battery energy storage system?
Battery energy storage systems (BESS) stabilize the electrical grid, ensuring a steady flow of power to homes and businesses regardless of fluctuations from varied energy sources or other disruptions. However, fires at some BESS installations have caused concern in communities considering BESS as a method to support their grids.
Which grounding products are needed for a turnkey system?
A reliable suite of grounding products is essential to a turnkey grounding system, including ground rods, grounding connections (compression, mechanical, exothermic), theft-deterrent grounding conductors, ground enhancement material, and cutting and crimping tools.
