2/ At Brits 3.5MWp (peak) solar may generate 1826*3.5 MWh per year = 6,400 MWh
However 1MW of this is potentially going into the battery so that it can be used later so the amount going straight into the plant would be 2.5 * 1826 = 4,565 MWh
3/ The Battery would produce 4MWh per day = 1,460 per year if charged once per day. Twice this if the system were grid tied and the battery was charged from cheap electricity from the grid overnight.
The cost of electricity is currently R2.6 per kWh (Or R2,600 per MWh, ..
4/ ..which is 163 US Dollars)
So if the battery is charged only once a day the potential saving per year is 982,000 USD. If the battery charges twice per day then the potential saving is 1.22M USD
5/ And this is just one .. small mini-grid ... the potential is absolutely huge for #VRFB and #BMN
