Globe shifts to hybrid power for cell towers

Globe Telecom, Inc. will utilize hybrid sources of energy for its cellular towers in Northern Luzon, Southern Luzon and Metro Manila.

It said on Wednesday it will tap solar-plus-storage plant or solar and diesel genset or a combination of both to energize its cell towers in off-grid and bad-grid sites.

“These hybrid power alternative sources are combinations of different technologies. These include a hybrid power plant or a mini-grid, which often contain a renewable energy component such as a solar photovoltaic (PV) system, supported via a second form of generator and/or storage such as a diesel genset and/or battery storage system.

Another technology is the Advanced Solar Hybrid Generator Set which uses solar power as an initial power source before shifting to the battery (rectifier) and diesel genset,” Globe said in a statement.

The move is meant to reduce Globe’s operational greenhouse gas emissions.

“The shift to hybrid power is part of Globe’s climate action strategy. We continue to move towards decarbonizing our operations in support of the company’s commitment to achieving Net Zero Greenhouse Gas Emissions by 2050,” said Yoly Crisanto, Chief Sustainability and Corporate Communications Officer at Globe.

Globe said these hybrid sources provide power for connectivity and access to digital services in rural areas that currently use diesel gensets due to limited or lack of access to a stable power supply. They are being piloted in off-grid tower sites and locations that suffer from power outages on a regular basis.

In 2019, Globe started its decarbonization journey by buying renewable energy bundled with verified carbon offsets through power purchase agreements aligned with the Philippines’s policy on renewable energy. To date, it has 14 key facilities running on 100 percent renewable energy and looks to add more sites this year, aligned with the government program on access to renewable energy for end-users.

At the same time, Globe has deployed over 8,500 green network solutions such as fuel cell systems, direct current hybrid generators, free cooling systems, and lithium-ion batteries to achieve energy and resource efficiency in its cell sites. These solutions use cleaner fuel with lower emissions, consume less diesel fuel, and provide energy-efficient heat removal.
