Rand Air, a member of the Atlas Copco Group, recently added the new ZenergiZe ZBC 250 to 500 kVA battery energy storage system to its hire fleet. The company says that although the energy storage unit cannot replace grid power completely, it would offer a clean, reliable, and efficient short-term solution where grid power is intermittent.

The unit can be used in combination with a generator and also has the ability to manage energy generated from intermittent renewable energy sources, offering a hybrid power solution for a wide range of industries. Moreover, micro-grids can be created to provide energy to residential, commercial, industrial or public service applications. Although the escalating price of diesel is pushing up the costs of running a generator, operators can reduce fuel bills significantly by alternating between the energy storage unit and a generator. In addition to consuming less fuel, running the generator for shorter periods will also reduce machine wear and subsequently maintenance and related costs.

The unit is noiseless in operation, requires virtually no maintenance, and particularly suitable in noise-sensitive environments such as events, filmmaking, shopping centres, etc.  At the heart of this powerful and compact unit are high-density lithium-ion batteries which are capable of providing over twelve hours of power. The batteries are lighter in weight than other technologies and the overall unit is 70% more compact than alternatives. This adds to effortless transportation and installation of the system.

The unit incorporates a number of connectivity features and benefits including a smart start-and-stop function, an Energy Management System (EMS) complete with battery management communication (BMS), a remote monitoring system, a Bluetooth mobile application as well as a parking mode.
