Consider this for an interim solution: Escom had installed ripple control for geysers and paid for it. Why not supply the municipality or contractors with circuit breakers to install on the supply point to consumers that limit there consumption of power, that way all will benefit . The breaker should be programmable and self resetting after 15 minutes giving the consumer time to switch off aircons and heaters ect.
When Cradock municipality had its own powerstation and was running out of capacity, had done it this way.
It is a case of adapt or sink.
Thanks for the chance to place my veiw
