The diversity of BESS technology allows its application to solve a number of different commercial and utility-scale energy consumption problems, including:
The most common motive to implement BESS technology into a commercial-scale solar power program is to further reduce electricity consumption costs. Peak shaving is one key energy consumption reduction technique that can be amplified with the installation of BESS technology.
Peak shaving is a concept used to significantly reduce the level of power consumed from the grid during peak consumption periods. Power drawn during peak consumption periods often carries significant tariffs, adding substantial costs to a commercial utility bill. Peak shaving allows a maximum cap to be placed on power consumption during peak periods, with the entity able to utilise energy stored within the BESS to cover the difference in operational consumption requirements.
Microgrids have long been touted as an alternative to the traditional ‘pole and wire’ power distribution network in Australia. Battery Energy Storage System technology is crucial to the increased adoption of this distribution method due to its ability to draw and discharge continuous power from the off-grid source both day and night. The self-sufficient characteristics of BESS technology solves a number of logistical challenges involved with the costly, ongoing maintenance of Australia’s pre-existing ‘pole and wire’ distribution network.
Uninterruptible Power Supply (UPS)
Coupled with the already highlighted benefits of the installation of BESS technology within a solar array, the technology also provides a form of Uninterruptible Power Supply (UPS), providing an emergency power source should you experience critical supply issues from the grid.
Battery Energy Storage Systems have far more to offer than a standard battery. BESS’s are packed full of advanced technologies, allowing the system to self-sufficiently capture charge from the connected solar array, optimise the ideal utilisation of the captured power, and execute the discharge of that power during identified ‘high-energy’ periods. Typically, Battery Energy Storage Systems will include the following technology:
The inclusion of an inverter into the Battery Energy Storage System facilitates the flow of electricity between the AC line voltage and the DC battery terminals. The inverter converts power between the AC and DC states, allowing the system to both charge and discharge the batteries.
The integration of high level control components into the BESS promotes self-sufficiency, allowing the system to monitor and control the performance of all internal technologies to ensure optimum efficiency. The control components are also utilised to analyse energy consumption data, allowing the system to discharge stored power during ‘high-energy’ consumption periods.
An extension to the integrated control components, sensors assist in ensuring the continued safe operation of the BESS. The inclusion of these sensors also allows accurate reporting on key aspects of the systems operation such as the ongoing monitoring of operational temperatures, identification of battery module failure and energy usage data reporting for both the operator and energy supplier.
Multiple Battery Modules
Further to the self-sufficiency theme, the inclusion of multiple battery modules ensures the systems continuity should one of the battery modules fail. This modular system allows the simple replacement of any failed battery modules without experiencing any downtime.
