PLDT wireless unit Smart Communications is expanding the use of solar energy in its cell sites using solar panels with battery storage systems as it pushes to operate a greener network and integrate sustainable solutions in its daily operations.
“The Solar and Energy Storage as a Service model will improve availability of power supply especially in areas where there is limited or no commercial power allowing us to serve more remote communities. This will also reduce Smart’s use of power from carbon sources.
Once fully implemented, we’re looking at a reduction of as much as 88 percent in greenhouse gas emissions in off-grid sites,” said Eric Santiago, PLDT and Smart first vice president and network head
Based on current proofs of concept, Smart sees opportunities for cost efficiencies in pursuing the program as it will also allow the company to extend mobile signal availability to customers in remote areas not connected to the electricity grid while also limiting dependence on diesel generators in case of power failures and emergency situations.
Smart added under the business model, a chosen supplier will install photovoltaic cells and a battery storage system in its cell sites and in facilities connected to the commercial power grid, the installation will help power the assets during peak hours and store surplus energy during off-peak hours for future use.
However, given the limited supply of non-conventional power from the market, Smart said it continues to search for more alternative power sources, particularly renewables.
