The National Grid Corporation of the Philippines (NGCP) revealed that its investments have resulted in concrete advantages for consumers with reduced transmission charges and fewer service interruptions. 

In a report from the Philippine Star, the NGCP shared that since the private sector assumed operations in 2009 until 2022, the rate of transmission outages in Luzon decreased to 1.3385% compared to the previous 6.4732% when the grid operator was under state control. This signifies a substantial improvement in service reliability and demonstrates the positive impact of private sector involvement.

In the Visayas region, transmission outages witnessed a decline from 6.6530% to 0.9508%. Similarly, in Mindanao, transmission outages were reduced from 8.0788% to 1.3285%.

NGC added that improved supply accessibility has led to intermittent transmission blackouts. 

NGCP data indicated that transmission availability in Luzon has risen from 99.2428% to 99.3160%. Additionally, availability in the Visayas region has increased to 99.6538%, while in Mindanao, it has reached 99.7206%. 

The capital expenditures have contributed to a significant improvement in the stability of transmission frequency in Luzon, reaching 99.9762%.

NGCP provided data showing that in the Visayas region, the transmission frequency experienced a substantial increase from 98.2116% to 99.6877%. 

However, in Mindanao, there was a slight decline in transmission frequency from 99.8890% to 99.8103%. The grid operator attributed this decline to the impact of El Niño in 2010, resulting in insufficient regulating reserves.

The corporation cleared that this generation issue is out of NGCP’s control. 

Since 2009, NGCP has invested Php 300 billion. Over the previous 14 years, these have included the installation of 31,190 MVA of transformer capacity, the building of 28 new substations, and the installation of 3,729 circuit kilometers of transmission lines.
