UK energy storage company redT energy plc (LON:RED) has sold 14 of its 40-kWh modules to an unnamed Botswana-based customer for use at communications infrastructure sites across the country.
“This represents a sizable commercial order for redT after deploying our initial units in South Africa,” said Scott McGregor, chief executive of the company, which sees sub-Saharan Africa as a key growth market.
redT’s energy storage systems are based on vanadium redox flow technology. The 14 units it will supply in Botswana will be installed in remote locations without grid connection and will be coupled with 11-kWp solar arrays at each site. The storage units will timeshift the solar generation, ensuring 24-hour power supply, which is cheaper than off-grid diesel generator off-grid, redT says.
According to the announcement, redT’s technology has been selected because of its long service life, low maintenance needs and ability to operate “at challenging sites such as these, where conventional lead-acid and lithium batteries have been used before and have experienced critical failure.”
