PE has been pretty open about where and how they want to go - Seems like NERSA is going to insist on Time of Use tariff for domestic in SA
Panels and Batteries will play and important role in reducing the cost of electricity

As you can see from the rates pasted below peak times you get hammered on the rate - You just need to move geyser etc out of peak and let the battery supply your evening usage .
The net billing ( dredit amount ) is well below what you pay

I think it is fair as the municipalities need to maintain the network and by using your excess generated they can effectively sell it on without having to buy from Eskom

They are being and have been installed in PE for the past couple years - I had installed in 2015 when I first installed PV at the office
In PE you have a 4 quadrant meter installed and they give you access on the system to be able to check your readings daily
All operates via GSM

Electronic metering and time of tariff usage has been around for a long time, landis and gyr were the pioneers and sometime still used in commercial and industrial applications. trying to get support from them is like dealing with a fibre serve provider

It use to be a money for jam service companies offer. They fit the meter get your reading sent to their office flip it and send it back to you at a fee, maybe throw in some power factor correction to make a few extra bucks. We were doing it back in 2004.
