How green is our city?

I thought that you might be interested in a green issue with the Cape Town City Council, writes our reader, Peter Brooks:

Their CTCC is claiming to be green – and they are doing some good things, like supporting solar water heaters and large solar farms.

City discouraging domestic PV generation

However, they’re doing their best, despite the capacity problems with Eskom, to discourage individuals from having domestic solar electricity panels fitted. They’re doing it by making the finances unattractive.

From their website:

Residential customers

Residential customers that want to be compensated for energy that they place on the grid will be required to move to the SSEG tariff structure and to have an industrial bi-directional AMI credit meter installed. The purchase and installation of this meter will be done by the City and will be for the generator’s account.

Residential small-scale embedded generation tariff comprises of the following charges which will be updated annually:

  • A daily service charge of R13.03 for the use of the grid.
  • An electricity consumption charge per kWh consumed. This is currently 109.17c per kWh.
  • The rate per kWh at which the City will purchase excess generation. This is currently 49.72c per kWh and is exclusive of VAT. The City of Cape Town will credit the consumer’s electricity account in Rands (not kWh’s).

Residential generators that want to connect to the grid, but do not wish to be compensated for energy placed on the grid can remain on their existing tariff structure, but will be required to install a device which blocks reverse power flow. The City of Cape Town indicates that it will not permit existing meters to run backwards.

They’ve reduced the amount they pay for electricity already from 56.28 to 49.72 – at this rate you have to give the city 26kwh free, as well as pay for the meter so they can rob you, before they’ll pay you anything, which really isn’t a good deal at all. If you do ever need to take net power out of the grid they charge more than double, so, to break even you have to put back 2kwh for every one you take out.

Nobody seems to have picked this up, so the CTCC is able to present a false green image. Perhaps you could help with an article exposing this.

Practical difficulties make savings inappropriate, says City

The City  responded as follows:

The City is certainly not trying to mislead residents with regard to environmentally friendly initiatives such as the Small-Scale Embedded Generation (SSEG) tariff. The City has always been completely transparent about potential financial benefits for SSEG users. In an ideal world, it would be the case that selling power back on the grid resulted in savings for the consumer/producer, however there are certain practical difficulties in this regard that we have to contend with that make this inappropriate.

It must be noted that the figures provided by the letter writer are in fact incorrect. A copy of the tariff is attached. Furthermore it is unclear where the ’26 kWh for free figure’ was drawn from.

The City refunds SSEG consumers who feed electricity back onto the grid at approximately the same rate we would have paid Eskom for that electricity. Paying SSEG consumers more than the cost of Eskom electricity would mean that the additional cost of buying this electricity would have to be paid by electricity consumers who do not have SSEG. So many residents in Cape Town cannot afford to install PV infrastructure in their homes, so to impose this extra cost on them would be unfair.

Furthermore, residential consumers (who generally are not registered as VAT vendors) will not be refunded VAT and will be compensated 56,68 c less 14% VAT which amounts to 49,72 c per kWh. This is a SARS requirement.

In conclusion the City is fully committed to the adoption of solar power, and progress towards a more sustainable future. The tariff was formulated not to exploit, but to ensure that costs of providing electricity are recouped, and so that those who are not financially able to invest in solar power for their homes are not forced to make up for the shortfall.

Council not understanding

Yet the issue was still not clarified, said Peter:

Unfortunately the council hasn’t understood the most important point. The 26kwh came from their figures without VAT.

Their figures from their website are:

Service Charge: R13.03 Per Day
Energy Charge – Consumption 109.17 c/kWh Energy Charge – Generation 56.68  c/kWh

Service Charge = R 13.03 per day = 1303 cents per day.
To generate this: 1303 / 56.68 = 23kWh

So every day, with their scheme, you have to give them 23kWh of generated electricity free before they’ll pay anything.

The average electricity consumption around the world is here. South Africans consume an average of 4,389 kWh per year = 12 kWh per day.

Home generators must produce a surplus

So the Cape Town council is asking people who generate their own electricity to produce a surplus of over twice the average consumption per house in the country! This makes it completely uneconomic.
The other way of looking at it is: With solar power you don’t get any electricity at night. So, if you generate all the power you need during the day but still need power at night – say half the national average, 6 kWh. Then the Cape Town city council will charge you:

109.17 * 6 = R 6.55 a day, on top of the R13.03 a day = R18.58 per day

If you have no solar power, then your nightly cost is:

153.63 * 6 = R9.12 per day.

So, help out by taking all your power of the grid during the day, and the City Council will charge you twice as much for your nightly consumption!

Either way you look at it that’s a huge penalty they’re imposing to discourage the use of electricity.

What service are you charging for?

If they stopped the ‘service charge’ (what service are you getting if you generate your own power that and ordinary consumer doesn’t get?… none) then it would be fair.

My point is that the ‘Service Charge’ of R13.03 a day means you have to either give 23kWh (26 if you exclude VAT) to them free before you get anything back – or you have to pay twice as much for your power at night.

Why is there this huge tax on home solar power?

The City will have the opportunity to respond again…
