My Facebook and Twitter feeds have been buzzing with confusion for the last couple of weeks since Botswana Power Corporation announced a new scheme to reduce power usage.
Load-shedding has been a fact of life in Botswana for years now, and recent announcements about a new scheme known as Demand Side Management have led to lots of noise across social media, mainly from people enquiring how to calculate their power consumption so they don’t get cut off.
With this post I hope to clarify some of the confusion and help people be better informed, you might even save money when you review what is using power in your house. Continue reading “Botswana Electricity – Load Shedding and Demand Side Management”

A couple of months ago I managed to sort out the installation (bit of a faff, but that’s another story), and now I can see how much power is being used at home from anywhere with an internet connection (as long as Orange Botswana keeps our Flybox online and the emoncms connection live). The nice thing about emoncms is that you can also embed the charts in your own website: Continue reading “Home Energy Monitor Feed”
