What is load-shedding and why is it occurring in South Africa?
In: 4
In an electric grid the energy load and the energy production have to match. If there is higher load then production the generators will not be able to keep up their speed so the frequency drop which can cause power lines to burn up as power flows from areas with enough production to match the load. This can cause cascades as surrounding power lines will get the full power.
So if the grid is not able to keep up production to meet the demand then they have to reduce the load on the grid. They do this by intentionally causing power outages. It is better to lose power in a neighborhood or a factory for an hour or two then to burn up the transfer cables and cause the entire power grid to be down for weeks.
