Well if you are concerned about the lights going on and off because Eskom is trying to keep a balance act going then I suggest you Google a bit and find the Eskom website and find a phone number and just contact them. I am sure they can answer all your questions regarding their planning and stuff. Also if you have the funds you can invest in counter measures such as expensive generators, notebooks and LED lights that consume less energy. You will find that there are a lot of costly but clever solutions to keep you running while the power is out. Good luck with that...
