It seems like NERSA are allowing grid-tie net-metering systems as long as they are "under the radar."
This means that as long as the systems never have a credit balance at month or year end, they are ok.
See Pick 'n Pay and Villiera who have installed systems in the past month.
If this is the case, then it is a win for South Africa. We have long awaited a ruling from NERSA regarding grid-tie and net-metering and perhaps by NERSA allowing these two high profile systems, it is telling South Africa, it's ok.
Note that grid-tie and net-metering is completely left out of the new IRP2010 process, ie the Integrated Resource Plan which sets out South Africa's electricity policies for the next 20 years.
