The National Grid Corporation of the Philippines energized on June 23 the Hermosa-San Jose 500-kiloVolt (kV) transmission line at its full 8,000 megawatts (MW) capacity.

A part of the Mariveles-Hermosa-San Jose 500kV facility will accommodate an additional 2,200 MW of supply from new power plants in Bataan and Zambales to the rest of the Luzon grid.

AT FULL CAPACITY — The Hermosa-San Jose 500-kiloVolt transmission line of the National Grid Corporation of the Philippines is now at its 8,000 megaWatts capacity, which means it can accommodate an additional 2,200MW of supply from new power plants in Bataan and Zambales to the rest of the Luzon grid. — NGCP photo

Line 1 was energized on May 27, 2023 to accommodate power generation in Bataan with a 2,000 MW transfer capacity, only a quarter of its full capacity pending the completion of the then unfinished portion of the line, and was fully completed on May 19, enabling a 4,000 MW line capacity.

The full completion of Line 2 will accommodate 8,000 MW in generation capacity, more than enough for existing and any incoming generation.

“NGCP completes this landmark energy project under the leadership and guidance of Pres. Ferdinand Marcos, Jr. This marks the full completion and energization at full capacity of this critical facility, strengthening and expanding the grid under NGCP,” the company said.

The Mariveles-Hermosa-San Jose 500kV line is comprised of 395 transmission towers, 275.6 circuit kilometers of transmission lines; two new substations; and 2,000 MVA in substation capacity.

While certified as an Energy Project of National Significance, the project still encountered various difficulties particularly on right-of-way due to opposition of landowners, long and tedious judicial processes, and protracted permitting process by local government units.

In July 2023, a portion of the line, owned by Phirst Park Homes, Inc., was the subject of a temporary restraining order issued by the Supreme Court.

NGCP stopped activities along towers 170 to178, stalling the ongoing stringing of the line’s remaining circuit from July 2023 to April.

The Mariveles-Hermosa-San Jose transmission line project was filed with the Energy Regulatory Commission at a cost of P 20.94 billion.

Its full completion and energization at full capacity are critical in accommodating additional power generation to the grid to prevent Luzon-wide power interruptions.

Of the actual cost of the Hermosa-San Jose line component of the project, the ERC has allowed NGCP to recover P19 million, or 0.1 percent of the project cost.

“With the completion of this critical project, NGCP is optimistic the ERC will act on the overdue recoveries applied for by NGCP,” the company added.

NGCP assured the public and its stakeholders it will continue to deliver on its commitment to improve, expand, strengthen, and reinforce the country’s power grid. – Press release
