THE National Grid Corp. of the Philippines (NGCP) has increased the capacity of its San Esteban Substation in Ilocos Sur to accommodate the growing generation capacity of wind farms in Ilocos Norte.
The power grid operator and transmission service provider said it upgraded its power transformer from 50 megavolt amperes (50MVA) to 100MVA.
With this expansion, NGCP boosts the capability and reliability of the power transformer to accommodate increased generation capacity from wind farms in neighboring Ilocos Norte.
These include wind farms operated by Energy Development Corp. (EDC) in Burgos, by North Luzon Renewable Energy Corp. in Pagudpud, and by North Luzon Wind Power Corp. in Bangui.
NGCP’s San Esteban Substation is a critical link to the grid as it transmits around 280 megawatts to the Luzon Grid.
The project also caters to the increasing load demand from connected power customers Abra Electric Cooperative (ABRECO), Ilocos Sur Electric Cooperative (ISECO), and Ilocos Norte Electric Cooperative (INEC).
The upgraded transformer was energized on September 5 at 11:30 a.m. The San Esteban Substation now has two 100-MVA power transformers.
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. led by Henry Sy Jr., Calaca High Power Corp. led by Robert Coyiuto Jr., and the State Grid Corp. of China as technical partner.
