THE Manila Electric Co. (Meralco)
and Japanese multinational conglomerate Hitachi Ltd. have put up a 2-megawatt
(MW) battery-energy storage system (BESS) in Bulacan.
“That’s a pilot. From a DU
[distribution utility] perspective, we want to understand how battery-energy
storage really works and how it will help the network,” said Meralco President
Ray Espinosa.
“We’re grateful to Hitachi for
providing us 2 MW of battery storage energy system that would acquaint our
network engineers on how we can use this energy storage system as a way of stabilizing
renewables,” he added.
Hitachi provided Meralco with 2,300
battery cells that can deliver 2 MW of power intermittently.
BESS’ are a subset of energy storage
Systems that can store energy to be consumed at a later time.
“As you know, renewables are not
that stable in a sense that they can fluctuate within the day, especially
solar, so the storage system is very important to provide that stability.”
The Meralco official further
described the BESS’ as “modular, movable and in 40 feet containers.”
Meralco and Hitachi inaugurated
early this month the San Rafael Battery Energy Storage System in Bulacan.
