ICT Growth proportional to Data
Growth/Internet penetration
Between 2010 and 2011
Almost all countries increased their IDI
values but..
… developed countries have twice the
IDI value of the developing ones

Sri Lanka’s power consumption based
on ICT (Telco) Infrastructure
UMTS network Access Rate per user ~ 1 Mbps
UMTS power per user ~ 4W
Mobile Data Subscriber ~ 1 Million
Power consumption of Mobile Data users ~ 4 MW
ADSL network Access Rate per user ~ 4 Mbps
DSL power per user ~ 8W
Fixed line Data subscribers ~ 500k
Power consumption of Mobile users ~ 4 MW
Estimated Energy Requirement for Data
consumption in Sri Lanka (2013) ~ 8 MW

Infrastructure solutions for Optimal
Energy Utilisation
Spectrum Re-arrangement for
maximum coverage with minimal basestation sites
Avoid network duplication through RAN
Sharing among operators
Provide energy to grid when power
generated during off-peak through NetMetering

have become constant
The increasing
demand will be
supplied in the future
through thermal
power plants
NRE sources have also
entered the play.

Electricity prices & Fuel Prices
Electricity prices have high correlation with world crude oil
prices

Higher proportion of thermal energy being powered through crude oil
In Sri Lanka future electricity prices will be more correlated
with coal prices

Telco Challenges - for Wind and Solar
Constraints on deployment of wind or solar system
Site Location – in the solar and wind map
Tower height
Site Area – considerable area required for solar
Hybrid solutions – to provide 24 hour continuous
power supply
Solar with Generator
Wind with Generator
Solar and Wind with Generator
Re-use existing Infrastructure
Eg: battery bank
Note: Wind is more efficient than solar
cells but much more scarce based on the
location of the site.

Conclusion
Data consumption will increase energy
consumption
ICT solutions and Infrastructure design
can be optimised through active
collaboration
Renewable Energy is cost-beneficial and
MUST supplement grid power
