This case study discusses the successful installation of Redflow batteries into a telecommunications base transceiver site (BTS). The BTS is located in a remote location in Latin America, accessible via rocky road and difficult terrain. The key site issue was an intermittent grid, meaning constant site downtime equating to loss of average revenue per user (ARPU), as well as an unreliable service for the customers of the mobile network operator (MNO).
An opportunity for small scale storage.
2.5 billion smart phones in 2018 and 4 million cell phone towers worldwide. Greatest growth in under-developed countries with unreliable power
Exponential increases in data creation and transfer mean that growth will continue. Increased demand for uninterrupted 24/7 access to global communications Challenges are greater in those areas without robust electricity grids, who experience daily or weekly outages of several hours or more…

This article reports about the successful demonstration of the RedFlow Zinc Bromine Module (ZBM) integrated into a standard telecommunication (Telco) DC system at -48V. The ZBMs, installed directly on the DC bus, can replace standard lead acid batteries and support the load when the power from the grid or from a diesel generator (DG) is not available. In this specific study, the ZBMs are used to integrate renewable sources (PV) with an existing DG allowing the coexistence of multiple sources, absorbing the load and PV fluctuations and most importantly reducing the DG run time.
Increasing electricity usage, international environmental concerns and their associated technical challenges have necessitated significant changes to the existing electricity infrastructure in many countries. Further advances in technology, especially in the communications sector, have also enabled additional monitoring of the electricity network. Two-way communications coupled with two-way power flows from new types of embedded generation have contributed to a revolution away from the traditional power grid. This is known as a Smart Grid, which “integrates and enhances other necessary elements including traditional upgrades and new grid technologies with renewable generation, storage, increased consumer participation, sensors, communications and computational ability” . Energy storage plays an important role in Smart Grids to achieve improved efficiency, reliability, sustainability and economic viability .
The University of Queensland (UQ) has installed the largest rooftop mounted solar PV array in Australia (1.2 MW), located on three of its buildings at its flagship St Lucia campus in Brisbane, Australia.
In mid-2012, RedFlow has installed its M90 energy storage system (90kW / 240kWh) alongside one section of the UQ solar field, marking our entry into the megawatt-scale class of energy storage systems. It was designed to store solar power generated from a 390 kW section of UQ’s PV array in the daytime, and feed it back into the local network at times when it is needed most.
