4 FAQs about 10MWh energy storage cabinet for South African telecommunications

Should South Africa consider alternative energy options for the telecoms network?

International case studies indicated that South Africa is not unique in considering alternative energy options for the telecoms network when the national electricity grid is unreliable, with hybrid renewable systems potentially a more cost-effective and greener option.

How do network operators secure electricity supply in South Africa?

Due to the distributed nature of telecommunication network infrastructure, network operators will secure their electricity supply through agreements with various municipalities and, in some instances, directly with Eskom.

How does Eskom reduce electricity usage?

This is done through a procedure called load reduction. Load reduction consists of two components, i.e. load curtailment and load shedding. Eskom's contractual arrangements with certain large industrial customers grant them the authority to direct these clients to decrease their electricity usage to maintain system equilibrium.

How much power does a telecommunications base station use?

Telecommunications base station operators have been utilizing diesel generator sets with capacities ranging from 7.5 kilovolt-amperes (kVA) to 25 kVA, depending on the maximum power consumption. The cost of electricity supplied via diesel generator sets is higher in comparison to power obtained from the grid (Deevela et al., 2023).
