I've just seen an interesting policy doc (not yet released, so can't share) which affects grid-tied SSEGs:
1. Municipalities to remove bureaucratic obstacles to connection of SSEGs to the grid. Recommends simple registration with no fees.
2. For RE systems up to 5kW: no compensation for feed-in (ie exporting power to the grid). "Net infeed into the network will not be compensated by the municipality in any month."
3. For >5kW SSEGs: Install 4Q meter at consumer's expense. Consumers to be credited with energy exports at the Eskom MegaFlex rate.
4. Policy is to move away from IBTs (Inclined Block Tariffs).
5. Abolish any price differences between prepaid and postpaid per kW charge.
6. Introduction of TOU tariffs in 2015. TOU = Time Of Use. So different prices for peak and off-peak consumption, priced to encourage load shifting to off-peak times.
7. Geyser control systems to be mandatory, but consumers can elect to pay a monthly fee (R50-R100) to not have ripple switches. Fines to be introduced for faulty or disconnected ripple switches.
