NGCP performance review intends to reconcile power system data

The propounded review of the operational performance of the National Grid Corporation of the Philippines (NGCP) is mainly intended to reconcile data which would be beneficial in pursuing prudent operation of the electricity system.

Energy Secretary Carlos Jericho L. Petilla said he raised some questions about how the power system operator has been reckoning supply-demand outlook – and he has been scouring for concrete answers.

The Energy Regulatory Commission (ERC), being the power industry regulator, has the sole mandate to enforce the third party review of the NGCP’s performance – but that is a step that Petilla has been firmly supporting.

It must be recalled that upon the request of the Wholesale Electricity Spot Market (WESM) operator – the Philippine Electricity Market Corporation – a third party scrutiny had been authorized by the ERC to be administered on NGCP’s system operations function.

“Yes, I have questions about NGCP data and we are reconciling that now,” Petilla said, noting that its major concern is on the actual trigger point on when a “yellow alert condition” must be declared by the system operator.

He stressed that there have been several instances in the past when reserve had gone below the required level, but a “yellow alert state” was not enforced by NGCP. Typically, this is the condition when reserve level had been pared way lower and power interruptions could ensue if more capacity will be taken out from the system.

Petilla qualified that an independent performance review on NGCP is only being done now because “there were so many things that the DOE has not really done in the past which we are doing right now.”

He added “it is better that we start this now… somebody should start an audit because it is really needed.”
