MARKET DYNAMICS
� Growth in rural areas
� Only 2% of African population with direct acess to electricity
Source: GSMA Report
Slide 1029.03.2011
OPERATORS CHALLENGES
� ARPU is declining
� 2009 Africa: $12 per month
� 2011 Africa: $7.4 per month & declining
� OPEX is increasing
� $2-$3K per BTS
� Cost of fuel increases
e. g. BTS with 4000 subscribers:
2009: $12 x 4000 = $48,0002011: $7.4 x 4000 = $29,6002012: $3 x 4000= $12,000 ??
Approx 60% decline in revenue for 2 years

BREAKDOWN OF SITE OPEX
• Energy / Diesel 50+%
• Personnel (maintenance): 20%
• Site rental: 10%
• Transmission 10%

HOW TO REDUCE OPEX
• Reduce the use of generator• Reduced diesel consumption• Reduced maintenance costs
1. Energy Optimization
• 96.5% efficient rectifiers• 96.5% efficient solar chargers
2. Utilization of
High Efficiency Converters
• Reduce the dependency on ACU3. Use Passive Cooling
Slide 1429.03.2011
• Cost to re-supply the fuel
• More frequent Gen-set maintenance & replacement program
• Possibility of fuel theft
In addition, there are other OPEX cost factor to consider:

Slide 2829.03.2011
EFFICIENCY MODERNIZATION: CUT LOSSES BY >50%
> If your power equipment is more than 5 years, it can be worth analyzing the benefits of upgrading to HE
> Upgrade can be done by replacing modules or power cores or power cabinets – not necessarily the complete system.
REPLACE your old power equipment
REDUCE operational cost and environmental impact
REALIZE rapid return on investment

POWER MODERNIZATION EXAMPLE
DC power system from 1987- Efficiency 80%- Plant capacity 180 kW- Floor space 19 cabinets
Flatpack 2 system- Efficiency 96,5%- Plant capacity 96 kW- Floor space 2 cabinets
AT 50% LOAD: ANNUAL SAVINGS (EXCLUDING COOLING) – 89 900 kWh
Slide 3029.03.2011
POWER MODERNIZATION EXAMPLE
PRS 5000 power system from 1997- Efficiency 88%- Plant capacity 20 kW- Floor space 5 cabinets
AT 50% LOAD: ANNUAL SAVINGS (EXCLUDING COOLING) – 84 900 kWh
Flatpack 2 system- Efficiency 96,5%- Plant capacity 192 kW- Floor space 3 cabinets- Reuse of distribution cabinet- Live replacement
