3. Present Telecom Operations Scenario
Revenue realization per minute Down
Minutes of usage Increasing
ARPU Declining
Passive capex spend Increasing
Grid availability Deteriorating
Operational cost Increasing
Double whammy: High operating costs for new
rollouts and lower ARPU resulting in strain on
EBITDA and margins

4. Telecom Operator’s success criteria
Ability to provide minutes at lowest possible cost and attract higher
number of subscribers is the critical success factor for the operators
Sell More
Minutes
Scope ???

5. Mobile growth = off-grid/grid-off areas
 Future mobile subscriber growth will be
heavily dependant on off-grid
populations.
 Today diesel generators are the
predominant off-grid power source,
however they are:
 Costly to run
 Require regular refuelling &
maintenance
 Negative environmental impact
 Diesel subject to theft
 In many parts of the world, available
grid power is often unreliable or it is
prohibitively expensive to gain access
 Diesel cost is increasingly high % of
OPEX

6. The Challenge with “Going Green”
 Green power is not traditional, core business
 CAPEX pressures - especially with current
market liquidity crunch
 Value chain is confused, and operators are Don’t let
unsure who can provide successful solution
 Often syndicates of players,
the
 Opportunity for niche players network
 What can be managed in-house? go down!
 Implementation and maintenance typically
outsourced to traditional local supplier
 Concerns about green power limitations on
network upgrades/evolution

9. Challenges for Infrastructure Co’s and Operators
35% of the Site Opex is related to Energy Costs
70% of the Site Downtime Issues
are related to Passive Infrastructure
99.99% SLA for Site Uptime
SLA Drivers
Diesel Generator
Battery Bank
Air-conditioning

15. Addressing Challenges
Challenges Contributor/Reasons ACME’s Solutions
Site • Various AC/DC Conversion Cost • Less/low AC/DC Conversion
Operation • Backup Cost • Low backup cost
Cost • Environment Conditioning Cost • Low Air-Conditioning Cost
• Over-design Infrastructure for • DC power house of 5 KW required
Peak Load (like 15KVA DG for
3KW load)
Site Main Reasons • NextGen thin Plate Technology
Downtime • Battery • Aviation grade very high MTBF
• Generator Generator
• Air-Conditioner • Compressor less N + 2 redundancy
Project , • Installation Time • Installation time (24-48 hours)
Operation • Expandability • Expandability modular
and • IT Interface for critical and • Energy metering for each operator
Maintenance operational need monitoring and their individual load
Cost • Detailed NMS
