Large-scale battery storage is the most responsive and flexible asset available to network operators, it can solve the issue with network volatility caused by the intermittent nature of renewable generation within the network.
As Nenghui battery storage solutions are bi-directional they can provide and absorb power from the energy network, smoothing out the intermittence of renewables by storing and distributing power when needed. Battery storage can be situated anywhere in the network to improve the flexibility and resilience of the entire network.
FLEXIBLE
a BESS can be charged with electricity from the utility grid when supply costs are low or by an on-site solar system
RESILIENT
Provides a source of backup power during periods of grid failure or power outages
