The feedback tariff (what they pay you) is fixed by NERSA, and the municipalities have to pay you back at that rate
Also NERSA have a “net consumer” requirement. I draw maybe 60 units from the grid a month. So I can sell back 59.99. At 60 something cents per unit that’s not a lot, though it might amount to a useful credit.
COCT have secured a waiver (two years or maybe one) for the net consumer requirement, and are offering (from some other cost center) and extra 25c per unit that you sell back. The latter is also time limited.
In all cases the killer is the meter. COCT are looking at a cheaper meter, and once they do that others will start using the same (a nice little earner for whoever has the franchise for that meter). But it will still be in the thousands of rands, and the householder will have to carry the cost of the meter.
In COJ, feedback is permitted
- At the NERSA rate
- Meter at your own cost - about 7 grand
- Net consumer requirement in place
- You have to switch to the resellers tariff with R700 to 800 a month in fixed fees before you’ve used or sold any power.
(4) may not be an issue if you’re on their standard post-paid tariff. You are paying those flat fees anyway.
But if, like me, you’re on pre-paid from City Power, it’s hard to see how you will so much as break even on the flat fees. Forget the cost of the meter.
So it’s hard to make a financial case for it as things stand.
My cynical take: Municipalities want to say 'OF COURSE you can sell back your surplus PV". And under their breath they add “you’d have to be stupid, but you can do it.”:
I wonder if there’s not a better way. I would happily give away my surplus power. I want nothing for it. But
- No cost to me
- There is no agreement that I will export X kWh per month (because overcast days happen).
I wonder how many other folks would do the same just to help out in their small way. Enough people doing a little can add up to a lot.
Unlikely they will got for such a scheme because then they will bear the cost of the meter replacement, so now how do THEY break even?
