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

Slide 2929.03.2011

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
