Electricity Block Tariffs

The Langeberg Municipality in compliance to NERSA ( the National Energy Regulator of South Africa) have

implemented block tariffs for households and/other single phase connection (<= 60 AMP) electricity supply from

1 July 2011. This means that electricity will be billed in correlation with the amount used per household.

What are Incline Block Tariffs (IBT)?

Incline Block Tariffs divide the electricity price into four steps or blocks. The first block of electricity is billed at the

lowest price. As the customer purchases more electricity during the month, the electricity bought will eventually

fall in block two which is a bit more expensive. This process repeats automatically as the customer purchases

further electricity and so moves into blocks 2, 3 and 4. At the end of the month, the history is reset and the

customer will again start the next month from block 1.

The process to move from one block to the next is automatic and depends only on the amount of electricity that

is acquired by the customer. The movement to the next block is not at all affected whether the purchases are

spread over many transactions or if all the electricity is part of one transaction.

Because the blocks’ increase in the price, customers can save money by not buying more electricity than what

they will use during the month. It is much better to wait until the next month and thus start to buy again at the low

price.

Below is a picture to show how these blocks are divided for the purchase total during a month:

Electricity is measured in kWh along the horizontal line at the bottom.

Incline Block Tariff Purchases per Month

The first electricity obtained for the month is always counted from the left and follow the blue line as electricity is

purchased during the month.

As more electricity is purchased beyond the step points, that portion of electricity will be at the higher price.

Remember the total electricity bought during the month determines the steps, not the date or the number of

purchases.

Who will receive Block Tariff electricity?



The Incline Block tariffs have been implemented for all Single Phase Connection <= 60 AMP which includes

households.

ELEKTRISITEITHEFFINGS: TOEPASSING VAN DAAGLIKSE VERBRUIKSMETODE

Langeberg Munisipaliteit het vanaf Julie 2011 blok tariewe ten opsigte van elektrisiteit implementeer vir alle

verbruikers met ‘n enkelfase elektrisiteitsaansluiting. Die beginsel van blok tariewe is dat hoër tariewe betaalbaar is hoe meer elektrisiteit verbruik word en die doel daarvan is om elektrisiteit-verbruik te ontmoedig. Die tarief van

toepassing op elke blok is die volgende:

0 – 50 kwh - 65c per kwh

51 – 350 kwh - 70c per kwh

351 – 600 kwh - 85c per kwh

Meer as 600 kwh - 90c per kwh



Verskeie klagtes is ontvang omdat elektrisiteitsheffings gebaseer is op tydperke langer as 30 dae, wat tot gevolg

het dat inwoners teen die hoër tariewe aangeslaan word vir die verhoogde verbruik as gevolg van die langer

verbruikstydperk(langer as 30 dae).

Aangesien dit nie prakties moontlik is om alle elektrisiteitsmeters in die munisipale gebied op dieselfde dag elke

maand te lees nie (ten einde ‘n 30 dae verbruikstydperk te verseker nie), is besluit om van die daaglikseverbruiksmetode gebruik te maak vanaf Desember 2011. Met die daaglikse verbruiksmetode word die blokke (0

– 50 kwh, 51 – 350 kwh, 351 – 600 kwh ) pro-rata herbereken teen die verbruikstydperk. Indien die

verbruikstydperk byvoorbeeld 35 dae is, sal die blokke as volg herbereken word:

0 – 57,53 kwh : (50 x12 maande / 365 dae * 35 dae = 57,53)

57,53 – 402,73 : (350 x 12 maande / 365 dae * 35 dae = 402,73)

402,7 – 690,4 : (600 x 12 maande / 365 dae * 35 dae = 690,4)

690,4 en meer

Met die daaglikse verbruiksmetode sal verbruikers nie benadeel word indien die verbruiktydsperk langer as 30

dae is nie. Dit is belangrik om kennis te neem dat indien die verbruikstydperk korter as 30 dae is, word dieselfde

beginsel toegepas en word die blokke verkort.

NB: Die heffings vir elektrisiteit, soos aangedui op die diensterekeninge wat Desember 2011 uitgestuur

word, sal dus op die daaglikse verbruik metode baseer word.

U aandag in hierdie verband waardeer.

ELECTRICITY CHARGES: APPLICATION OF DAILY CONSUMPTION METHOD

Langeberg Municipality implemented Inclining Block Tariffs (IBT) as from July 2011 for consumers with a single

phase electricity connection. The principle of block tariffs means that, higher tariff is charged for higher

consumption, meaning the more electricity you consume, the more you pay and the purpose is to encourage

electricity savings. The blocks per tariff are the following:

0 – 50 kwh - 65c per kwh

51 – 350 kwh - 70c per kwh

351 – 600 kwh - 85c per kwh

More than 600 kwh - 90c per kwh

Many complaints has been received regarding electricity charges that was based on consumption periods for

longer than 30 days, as the consumers were charged against a higher tariff for increased consumption due to the

longer consumption period.(longer than 30 days)

It is not practically possible to read all electricity meters within the municipal area on the same day each month

(to ensure a 30 day consumption period), hence it has been decided to make use of the daily consumption

method as from December 2011.



Re-calculated on a pro-rata basis according to the consumption period i.e if the consumption period is 35 days

the blocks will be recalculated as follows:

0 – 57,53 kwh : (50 x12 months / 365 days x 35 days = 57,53)

57,53 – 402,73 : (350 x 12 months / 365 days x 35 days = 402,73)

402,7 – 690,4 : (600 x 12 months / 365 days x 35 days = 690,4)

690,4 and more

With the daily consumption method the consumers will not be disadvantaged if the consumption period is more

than 30 days. It is important to note that if the consumption period is shorter than 30 days, will the same principle

will be applied and the blocks will be shortened.

NB: The electricity charges, as indicated on the service accounts that will be provided in December 2011,

will be based on the daily consumption method .
