PLDT, Smart push for energy efficiency

PLDT and subsidiary Smart Communications Inc. reinforced their commitment to actively ensure responsible energy use.

The PLDT Group submitted its Annual Energy Efficiency and Conservation Report (AEECR) and Annual Energy Utilization Report to the Department of Energy (DOE) in compliance with the Energy Efficiency Conservation Act (EECA),

Under the EECA, designated establishments from the commercial, industrial and transport sectors are required to submit energy disclosures annually, with 2020 as the maiden reporting year.

Designated establishments are those that meet the annual energy consumption threshold of 100,000 kilowatt hours and above.

The reports submitted to the DOE cover the PLDT Group’s over 10,000 cell sites and 200 offices, business centers, and data centers, and will serve as a baseline from which progress from energy efficiency initiatives will be measured.

The PLDT Group has identified energy efficiency as one of the key areas that will ensure sustainable operations in its delivery of its products and services, and has started to adopt initiatives that aim to reduce its energy consumption.

Smart recently announced its foray into fuel cell-powered sites, an environment-friendly alternative that will simultaneously address connectivity issues in challenged-grid areas nationwide.

The system is based on methanol-powered fuel, which can be combined with solar, wind and other renewable resources to present a sustainable, cost-effective eco-system.

PLDT, on the other hand, has upgraded chillers in its facilities in Sampaloc, Ortigas and Dansalan to optimized oil-free versions.

These provide the highest efficiencies and reliability by eliminating conventional challenges brought about by oil issues.

Chillers are the biggest single power consumer in any facility and typically consume 30% to 50% of a building’s power.

The switch to oil-free magnetic bearing chillers eliminates the use of lubricating oil on chiller compressor bearings. This reduces bearing pressure, making the compressor more efficient and in turn, result in lower energy consumed.

The magnetic bearing also ensures reduced mechanical maintenance. This means equipment life is not reduced by increased hours of operation. Savings estimated for the chiller replacement initiative can be up to 60%.

“As greenhouse gas emissions arise from energy consumed in the operation of our business, particularly by our network, our offices and data centers, and emissions from our transport vehicles, the PLDT Group aims to do its share in protecting the environment through energy efficiency programs that will result in reducing our carbon footprint,” PLDT chief revenue officer and Smart Communications president and CEO Alfredo S. Panlilio said.
