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 equated to a loss of average revenue per user (ARPU), as well as an unreliable service for the customers of the mobile network operator (MNO).
BRISBANE, QLD, AUSTRALIA, 2012: 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.
NEWINGTON, NSW, AUSTRALIA, 2012: The Australian Government has chosen Ausgrid to lead a $100 million initiative across five sites in Newcastle, Sydney and the Upper Hunter regions (see Figure 1). Smart Grid, Smart City creates a testing ground for new energy supply technologies. At least 30,000 households will participate in the project over three years. The demonstration project gathers information about the benefits and costs of different smart grid technologies in an Australian setting. Building a smart grid involves transforming the traditional electricity network by adding a chain of new, smart technology. It includes smart sensors, new back-end IT systems, smart meters and a communications network.
Ausgrid and the Australian Government
Ausgrid is a major utility in New South Wales Australia. In conjunction with the Australian Government’s Smart Grid, Smart City trial, Redflow installed sixty R510 residential energy storage units in Newcastle and the Hunter Valley as part of the Australian Government’s Smart Grid, Smart City project. Redflow’s involvement with this part of the project extended from late 2011 to mid-2013. Another R510 was also installed as part of the Newington Smart Home sub-project. Redflow began its involvement with this trial in 2010 with a lead-acid energy storage system, after which the system was upgraded to an R510 in late 2011 before ending its time at the Smart Home in mid-2013. Please see the Smart Grid, Smart Cities R510 Case Study for more information regarding Redflow’s experience with Australian utility, Ausgrid, of the design, installation and operation of 61 R510 electricity storage systems in New South Wales, Australia. Redflow’s Whitepaper also provides an overview of key results and lessons learnt from the project.
Ergon Energy Corporation
Ergon Energy is the Queensland Government-owned electricity distributor to regional Queensland, with an asset base of $8 billion and more than 650,000 residential and business customers. RedFlow supplied 30 ZBM systems for installation and integration within the Ergon Energy electricity supply network, as part of the Australian Government’s Advanced Electricity Storage Technologies (AEST) program. The systems were used for managing peak electricity demand within three locations in Ergon Energy’s rural network and were remotely monitored by both RedFlow and Ergon Energy.
