NGCP upgrades Cagayan substation


THE National Grid Corportion of the Philippines (NGCP) has increased the capacity of its Tuguegarao Substation to accommodate the incoming demand from a new airport and several local businesses in four provinces in Northern Luzon.

Lilibeth Gaydowen, NGCP Northern Luzon corporate communications and public affairs officer, said it upgraded its power transformer from 90 megavolt amperes (90MVA) to 190MVA.

She said the additional 100 MVA power transformer energized and commissioned at NGCP’s Tuguegarao Substation is a facility improvement which is part of the system operator’s Luzon Substation Expansion Project.

The facility improvement will benefit customers from Cagayan, Isabela, Kalinga and Apayao provinces.

“With this, the substation now has more room to transmit additional power supply from new generators and to accommodate the incoming demand from Lallo airport and several local businesses in the area,” Gaydowen said.

She said the demand for power has always been increasing not only from customers in these four provinces but also because of the El Niño phenomenon when temperature continues to rise, especially in Tuguegarao City, which is one of the hottest places in the country.

Gadowen added that this development is the result of a series of substation expansions to ensure that the company’s facilities operate at an optimal level, and at the same time are ready to sustain an increase in both power supply and demand.

“With the additional 100 MVA, we can assure our customers, particularly those connected to CAGELCO I, CAGELCO II, ISELCO II, KAELCO, and the National Irrigation Administration of reliable and more efficient power transmission operations.

“The company is confident we can replicate this achievement in North Luzon throughout the rest of our facilities,” she added.

NGCP is a privately owned corporation in charge of operating, maintaining and developing the country’s power grid.

It transmits high-voltage electricity through “power superhighways” that include an interconnected system of transmission lines, towers, substations, and related assets.

The consortium, which holds the 25-year concession contract to operate the country’s power transmission network, is comprised of Monte Oro Grid Resources Corp., Calaca High Power Corp., and the State Grid Corp. of China as technical partner.
