DUMAGUETE CITY (PIA) – The National Grid Corporation of the Philippines (NGCP) recently held a “Power 102” briefing in this city to inform local media and public information officers in the province on the developments of NGCP’s expansion projects in Negros Island.

NGCP’s Visayas Systems Planning Division head Engr. Hannel Tamayo head told attendees of the forum that the transmission company targets to complete the installation of three additional transformers in Negros Island by September 2016.

One of which is the 150 Mega-Volt Ampere (MVA) transformer in Amlan, Negros Oriental while the other two are the 100 MVA transformer in Bacolod City and 150 MVA transformer in Cadiz City, both cities are in Negros Occidental.

Another project which is set to be completed next year is the construction of 69KV transmission line project on the eastern side of the island.

The purpose of the project is to create a 69KV loop that will serve as connection points of several plants to be located in the area, he said.

Another project in the pipeline is the completion of the Cebu-Negros-Panay (CNP) 230KV backbone transmission line.

Engr. Tamayo said this is one of NGCP’s biggest project in the Visayas. He explained that this will be a “highway” that enable electricity to pass higher capacity lines instead of passing through 69KV or 138KV transmission lines that link the three provinces.

The first phase of this project is the construction of the Negro-Panay interconnection line which is expected to be online by April next year.

The second phase is the completion Cebu 230KV overhead line. This is expected to be online by 2017.

Once these two projects are completed, the next thing to do is to link Negros and Cebu through and overhead line from Bacolod City to San Carlos City then to San Carlos City to Toledo City, Cebu through a submarine cable, this will be the third stage of the over-all project.

The advantage of this project is that power plants in these three islands won’t be curtailed.

“In case some of the plants in Negros and Panay fails, other islands can always support each other,” he said.

Aside from this, the CNP backbone project will also address the big disconnect between the projected power supply and demand figures in the coming years.

Engr. Tamayo presented the projected power supply and demand figures for 2016 to the attendees of the briefing.

He explained that for Panay Island, if all generation plant project pushes through, the expected number of power supply is 785 Mega Watts (MW) and the demand to increase to up to 335MW and the excess power would be pegged at 450 MW.

In Negros Island, given the same condition, the expected figures for power supply is expected to rise to 1, 28.2MW while the demand is expected to reach 288MW with an excess of 740MW.

Combining the figures from Negros and Panay, the figures for the power supply is expected to reach up to 1,814MW while the demand is pegged at 623MW with an excess of 1,011MW.

These projections were based on NGCP applications and power generation components.

In the case of Cebu, the island is considered as the center of power demand, this means if there is an excess of power in Negros and Panay, power will eventually be gravitated towards Cebu.

However, current NGCP facilities only allow power to be transmitted from Negros to Cebu 180MW through two submarine cables that link Negros Oriental to southern Cebu.

“Based on the demand, supply and the capacity of the plants, we are expecting that the maximum of power to be generated without overloading our submarine cable is around 842MW during peak hours,” he noted.

“In here we see, that we have 1,814MW of supply and we can only generate up to 842MW so there is disconnect (in the numbers). This is the existing challenge for NGCP,” he added.

Once the 230KV backbone transmission line is fully operational all the excess power will be transmitted in the three islands easily.

Aside from giving updates on their expansion programs, other NGCP officials addressed issues on power transmission in the said briefing. (mbcn/ral/PIA7-Negros Oriental/This article was first published at PIA website on November 18, 2015)
