Orania in the Northern Cape recently took delivery of a large battery energy storage system (BESS) that will help the town avoid the first six stages of load-shedding.
Orania’s electricity distributor, Orasol, told MyBroadband that the 4.8MWh BESS offers 4.3MWh of useable capacity with a maximum output of 2.75MW.
The BESS consists of multiple lithium-ion battery cells with a control system that can manage battery levels at the cell level. It also features liquid cooling for optimal thermal management.
Orasol said the battery’s primary purpose will be to provide the town with an uninterrupted electricity supply during power outages, going up to stage 6 load-shedding.
The town currently has a demand of around 1.2MW, with a peak demand of 1.9MW.
That means the BESS would be able to supply power to the entire town for around two hours in peak periods and three to four hours at other times when fully charged.
That excludes the contribution of Orasol’s 1.25MWp solar power farm, which first entered operation in late 2022 and is already capable of supplying 30% of Orania’s electricity demand.
Together, the solar farm and battery will be capable of providing Eskom-free power to the town from 06:00 to 22:
