JSE-listed real estate investment trust Growthpoint Properties is piloting a 4.5 MW battery system at Paarl Mall, in the Western Cape, for continuous, cost-efficient power supply, which will be partly charged by Paarl Mall’s new rooftop solar photovoltaic (PV) plant. The R50-million system will extend the positive impacts of renewable, sun-powered energy around the clock, the company says.
