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.
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.
A recent six-year audit by Clean Energy Associates found that over 25% of grid battery systems had manufacturing defects, putting them at high risk in these areas. The most common causes of defects were quality control issues from the assembly and installation of integrated systems, such as the grounding and bonding components.
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.
