One of the biggest contributors to the carbon emissions and energy consumption is
the running of the telecom infrastructure especially the telecom towers. A Telecom
tower enables telecom operators to provide network connection to mobile users.
Telecom being an essential service requires the network needs to be always available.
Energy needs of a telecom tower in India are currently met through:
Diesel Generator and
UPS / Battery Racks
Since, Electricity supply is erratic and is not available throughout the day in
many parts, Diesel Generators (DG) are used to power the telecom network, as a backup
for power supply
DG’s are operational for of 8-10 hours (avg.) in rural areas and 3- 5 hours in urban
areas, putting a stress on the environment by way of carbon emissions
and noise pollution
20-30 litres (avg.)of Diesel is consumed per tower per day
One liter of diesel emits 2.6 kg of CO2 emissions
India currently has approximately 250,000 towers with 350,000 tenants. This is expected
to increase to 450,000 towers with 900,000 tenants in next three years. Given the
power outage in India, each tenant currently consumes on an average almost 3000
litres of diesel every year on a shared tower. This means telecom industry is expected
to consume 2.5 – 3 Bn litres of diesel every year, depending upon the extent of
The usage of diesel has been contributing close to 5.3 Metric tons per year of Co2
emissions, and this is only expected to go up post the 3G and BWA roll outs. Especially
the black carbon emissions would translate to 35-40% higher overall climatic burden
than just co2.
Moreover, the energy management costs have become one of the concerns for the telecom
operators with energy costs coming to app 25% of operational expenditures.
Global Group is focusing on energy management solutions as part of its vision of
an efficient and environment friendly telecom Industry and is taking a leadership
role in reducing the energy consumption and related carbon emissions through their
innovative Energy Management service offerings. GTL’s green energy based Energy
Management Solution are targeted to reduce the energy requirements by up to 20%.
The Company has committed investments of over `
2,400 crores for developing and
implementing the green Energy Management Solutions.
GTL and other Global Group companies have been approaching the issue from the Demand
side and supply side. From the demand perspective, the innovative green energy solutions
use the combination of the following
Efficient use of installed equipment, ensured through Energy Audit and remote monitoring
Reduced energy consumption by adopting free cooling methods in combination with
Reduced diesel consumption by optimizing the DG and use of alternate fuels
Using Deep discharge
batteries to reduce DG operating hours
From the supply side the Group would be deploying green energy based solutions that
will be using alternate sources of energy like Solar PV systems, Micro Wind Turbines
The Group's efforts should result in
Contributing towards building a greener, cleaner environment with reduced carbon
Saving on OPEX by reducing power consumption through energy saving engineering solutions
Ensuring uninterrupted power at the site increasing total site availability in the
Increasing equipment shelf life by ensuring healthy power at the site
