  • 1. Conference on Rural Telecom- Telecom- ACME Energy Efficient Telecom Solutions ACME Tele Power Ltd. Plot no. 2, Sector-34 Sector- EHTP, Gurgaon, Haryana, INDIA Main: +91 124 456 1800 Web: www.acmetelepower.com www.acmetelepower.com Conference on Rural Telecom India 2009 1
  • 2.  The Green Business Challenge  Understanding energy use and challenges at telecom sites  Trends in Power Management Solutions  Solution Comparisons and Recommendations www.acmetelepower.com Conference on Rural Telecom India 2009 2
  • 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 www.acmetelepower.com Conference on Rural Telecom India 2009 3
  • 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 ??? VAS OPEX www.acmetelepower.com Conference on Rural Telecom India 2009 4
  • 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 www.acmetelepower.com Conference on Rural Telecom India 2009 5
  • 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 www.acmetelepower.com Conference on Rural Telecom India 2009 6 6
