Proposed tariffs for solar users

Yes and no.

I think the argument is not just an Eskom thing; the famous duck curve is well-known and used by power utilities across the world. I don't think it's entirely hogwash, but it is more applicable to pure grid-tied systems. Customers that would normally be drawing at least their baseload power during the day would instead get it from solar, but as the sun goes down their demand goes from near-zero to full evening peak load. The steeper ramp-up curve is real, and it forces utilities to make greater use of gas or diesel peaker plants if they cannot ramp up the cheaper coal or nuclear power stations as quickly as solar forces them to.

How can one deal with it fairly and effectively? I think by switching to Time-of-Use tariffs if one goes onto solar (thumbs-up Nelson Mandela Bay Metro), and also to enforce the lowering of Notified Maximum Demand when going on solar, thereby incentivising solar users to meet the evening peak demand with battery power. These days hybrid grid-tied inverters with time-of-use and peak-shaving features are common, and the cost of lithium battery storage has come down enough, so that is a real alternative.

Eskom must just think further, and not just use tired old arguments and half-truths to cover up for their shortcomings.

But one of eksdom's excuses for load shedding is that they need to build up their depleted reserves. So why can't they do it during the day when the sun is shining and our pv systems produce power for us? Prepare to be screwed again/still.

With all the highly educated bullS..t that are spread by Eskom and the motivations for this fixed tariff. 

Just think of it this way:

If they want to charge you R938-00 fixed tariff (infrastructure uphold and maintenance), then when we as solar power producers, export to the grid as they propose, we should charge them R938-00 for infrastructure uphold and maintenance and then export kWh to the grid. It negates there argument. That seems to me to be a fair system. What do you guys think?

"Consumers use solar to generate most of their electricity during the day, which Eskom argues forces it to ramp up at a faster rate to meet evening demand. This has a significant negative impact on the power system, Eskom said at the time."

What a lot of intelligence undermining hogwash.
Had there not been a solar user the demand in the evening would be exactly the same as it is now. There used to be a finite amount of power that they could generate with all their power stations. Their lack of skills and maintenance over the last 2 decades has firstly halved the generating capacity and secondly, the induced failures on those power stations still operating has further caused a halving of the generating capacity again. 
These power stations were funded by none other than the tax payers. These same tax payers then funded even more power generation by starting their own generation at home, be it solar, wind or other means , primarily to not be dependent on an intermittent service whose base fees are based on 24/7 service. This takes the pressure of the failing system.
They know darn well that the demand at night has always been constant, yet they blatantly spread garbage statements like this to place the blame on those consumers that are actually pro-active and as a result try to support a more stable system. Another example of creating a two tier society where those that depend purely on Eskom are used as political puppets to gang up and tax those that are trying to create a better solution.
Those that still accept and swallow these Kindergarten style official statements must be indoctrinated to the core or have lost their own ability of thought. 

Well said

You've bought media propoganda six love. Or are you an Eskom direct customer with a 3 phase, 24kVA connection?
