The MAGIC NUMBER
(Average Increase)
NERSA Guideline for 2012/13: 20.73%
Small Power Users
Small Power User 1:
Service Charge:
R20.54 per day
(19.3% Increase)
Energy Charge:
110.85c/kWh
(19.0%)
Service Charge increases slightly above average due to 1 less day in
the year
Small Power User 2:
Energy Charge:
173.33c/kWh
(19.9%)
Slightly above average increase to ensure crossover with SPU1 is at
exactly 1000kWh per month.
Large Power Users
Large Power User LV
Service Charge:
R34.21 per day
(19.3% Increase)
Energy Charge:
58.12c/kWh
(19.0%)
Demand Charge:
R172.93 per kVA (19.0%)
Large Power User MV
Service Charge:
R34.21 per day
(19.3%)
Energy Charge:
54.03c/kWh
(19.0%)
Demand Charge:
R160.83 per kVA (19.0%)
Time of Use
Renamed Medium Voltage Time of Use
Service Charge:
R5 580.00 per day
(19.2% Incr)
Peak
273.87c/kWh
(19.0%)
Standard
72.42c/kWh
(19.0%)
Off Peak
39.42c/kWh
(19.0%)
Peak
77.75c/kWh
(19.0%)
Standard
48.24c/kWh
(19.0%)
Off Peak
34.21c/kWh
(19.0%)
R86.87 per kVA
(19.0%)
High Season Energy:
Low Season Energy:
Demand Charge:
High Voltage Time of Use
For 66kV and 132 kV connections
New tariff for 2012/13
No existing customers will qualify for this tariff, solely for new
connections, therefore no impact to existing sales base
Based on MV Time of Use with a 3% discount on energy to cater for
lower losses at these levels
Voltage level determined by the existing transmission voltage level –
NOT customer choice
Other notes
SPU with Off Peak combination for 2012/13 is limited to existing
customers only.
Off Peak Tariffs increases by 29.9% as first step in phasing out
Impact of discontinuing tariff completely in one year would be too large
Net Metered Domestic Tariff remains equal to the Small Power User
Tariff, which is also the tariff for Net Metered Small Power consumers
LPU and TOU customers with embedded generation remain on their
existing tariffs, with the energy and demand components reflecting
the load placed on the system (i.e. the energy component reflects net
energy consumed, and the demand component the maximum
demand utilised.
Despite the above, the City is not quite ready to offer these products,
but will be in the 2012/13 financial year.
