Projected Load Profile
The demand for electricity
is growing steadily at around 3%
per year…
New capacity requirement
Existing capacity
And what that means…
Every three years
we need one base load
power station
1200MW 1200MW 1200MW

What is DSM?
•
Create predictable changes in
customer demand and load profile
•
Alternatives to the provision of
additional generation plant.
•
Includes load management, peak
clipping and energy efficiency
Long term DSM target
8000 MW
To be achieved by 2025
…basically a saving of two base load power
stations

EEDSM Pillars
• Economic
– Lower cost than generation plant
– Lower lead time to implementation
– Better utilisation of national resources
• Environmental
– Lower environmental impact (coal, water)
– Low GHG emissions
• Social
– Job creation
• Sustainable
– Change consumer behaviour
Barriers to speedy EEDSM roll out
•
Shortage of technologies locally
•
Shortage of specialised professionals trained in EEDSM
•
Energy efficient products of low quality (Import market)
•
Uncertainty with reform of Regional Electricity Distributors
(Municipalities)
•
Development of agreements
•
Development of the ESCO market
