Nexus Energy Storage Systems

Nexus Power energy storage system (ESS) provides supplemental power and redundancy. It provides increased system efficiencies through better energy management, minimizing diesel generator and grid supply dependencies. The drop-in-place design enables a simplified and efficient integration into existing power plants. It is built upon Nexus Power advanced active front end (AFE) power conversion design integrated with customisable energy storage technologies to suit specific applications.

Nexus Power ESS has plug and play unit operation. Each container unit is autonomous, increasing system reliability. The energy storage housing includes integrated environmental controls and system cooling in self-contained modules. The housings can be tailored for specific site applications and with the parallel unit configuration it allows for scalable energy storage solutions

Nexus Power ESS strengthens an installation’s power grid through power regulation and can allow for deferral of investment in power distribution and transmission. The energy storage system provides cost savings opportunities through reduced utility bills by lowering demand charges and providing the ability to participate in demand response programs.

The energy storage system monitoring and controls are integrated within the control station interface. The system monitoring provides remote connectivity enabling external system monitoring.

Other features include:
Transmission Connected Voltage Control.
When properly located Nexus Power ESS can help maintain acceptable voltage levels in transmission zones.
