Smart Metering and Smart Management• Key enabler for savings through other actions;• Allows remote measurement and management: consumption, power quality, temperature, etc;• Provides billing optimisation, mitigating errors and reducing consumption estimates;• Incentives, dues and fees optimisation;• Strategy can be combined with infrastructure CAPEX optimisation, eg Batteries.

More Efficient Infrastructure and SelectiveSwitch-Off
Old generations of Rectifiers can be renovated using the power savings to pay the bill. Four years payback periods are not difficult to find.

Free-CoolingTechnical Buildings and Cell Sites can use much less air conditioning. In many cases it is possible to eliminate the air conditioner and use pure free-cooling.

Green Self-Generation
Chile: Hybrid System in Punta Arenas
Ireland: Auto-Sustainable Solution (Wind and Solar) in
the north of Dublin
Mexico: Solar Panels in

Telefonica has already 225 renewable base stations, as well as many renewable fixed sites.We are currently performing an assessment, supported by GSMA, to implement
another 100 sites in Latam in 2011, aiming at 3 years payback periods.
