Telco network goes green

Globe Telecom Inc. currently employs over 7,400 green solutions to reduce carbon emissions across its network.
Better yet, by 2030, it will upgrade its infrastructure and retrofit its industries to make them sustainable and slash CO2 emissions by 30 percent, the telco today (May 25) stated.
“We continue to engage partners in implementing renewable energy solutions such as solar panels and fuel cells within our operations,” explained President and Chief Executive Officer Ernest L. Cu
Already, the telco consumes cleaner fuel at lesser quantities, achieving lower emissions and maintaining energy-efficient heat removal throughout its operations.
Globe has been deploying green network solutions since 2014.
These include fuel cell systems, direct current generators, lithium ion batteries and free cooling systems.
The telco monitors energy and emission data on a monthly basis and conducts data validation on a quarterly basis.
As of 2020, tlit has deployed a total of 203 fuel cell systems, 6,467 lithium ion batteries, 212 Direct Current Generators, 60 DC-Hybrid Generators, and 538 free cooling systems across its network.
Fuel cell systems produce less emissions compared to traditional generator sets, and operate silently thereby reducing noise pollution in surrounding areas.
Globe started deploying fuel cell systems in 2014 as a green solution alternative to diesel generator sets that provide backup power to cell sites.
On the other hand, it intends to replace lead-acid batteries used in powering cell sites with lithium ion batteries.
This green solution is more heat-resistant, has a faster charging time, and has an operational life that is ten times longer than traditional lead-acid batteries.
Furthermore, it translates to less waste generated over time while maintaining a more efficient back-up power system.
In addition, the telco has been using DC generators and DC-hybrid generators for several years now to reduce fuel consumption, and provide a more cost-efficient solution for open field sites.
It has also used free cooling systems (FCS) to reduce power consumption of air conditioning systems at field sites.
FCS uses controlled ambient air flow to maintain the optimal equipment operating temperatures within a cabin without compromising reliability and availability.
Significantly, Globe implements an ISO 14001-certified Environmental Management System and commits to environmental transparency via the Climate Disclosure Project.
The telco supports the Race To Zero global campaign led by the Framework Convention on Climate Change (UNFCCC) and backed by the GSMA, the global mobile industry body.
This activity is part of the GSMA’s bid to lower greenhouse gas (GHG) emissions to net zero no later than 2050 through the collective efforts of all mobile network operators around the world.
