NGCP Power System update

Let me give another POWER SYSTEM UPDATE (as of February 23, 2010). this was sent to me via email by Belinda Sales Canlas of the Corporate Communications Division of the National Grid Corporation of the Philippines (NGCP)

According to transmission utility and system operator National Grid Corporation of the Philippines (NGCP), no Luzon grid customers are expected to experience power interruptions today as long as all running power plants stay connected and synchronized to the grid. With 662 MW of reserves, the Luzon grid remains stable and under normal status.
The power grid status today is as follows:

Grid / Available Capacity / Peak Demand / Reserves / Generation Deficiency
LUZON / 7,382 MW/ 6,720 MW/ 662 MW / 0 MW
VISAYAS / 1,129 MW / 1,167 MW / 0 MW / 38 MW
MINDANAO / 842 MW / 1,200 MW / 0 MW / 358 MW

The Visayas islands will continue to experience generation deficiency. Geothermal plants, which comprise around 70% of Visayas grid’s power source, have a total available capacity of 730 MW out of the total rated capacity of 936 MW.

The Luzon grid is already exporting up to 20 MW to augment the available capacity of Visayas.

In Mindanao, the generation deficiency is now at 358 MW, a marked increase from yesterday’s deficit of 183 MW.

The said deficiency is caused mainly by the reduced capabilities of hydro-electric plants due to low elevation at water reservoirs. Today, there has been an 80% and 60% reduction in the available capabilities of Agus and Pulangi Plants, respectively. Reduction in the capabilities of Agus and Pulangi Plants yesterday was at 70%.

Agus Plant is now running at 120 MW out of total rated capacity of 727 MW while Pulangi is running at 100 MW out of total rated capacity of 255 MW.

Also contributing to the deficiency in Mindanao is the non-availability of Iligan Diesel Power Plant (35 MW) and the planned outage of Power Barge 117 (50 MW).

The continuing generation deficiency will result in the curtailment of power load transmitted to Mindanao grid users.

Customers are advised to coordinate with distribution utilities or electric cooperatives in their area for information on the schedule and areas to be affected by the power interruptions.

NGCP will continue to monitor power grid conditions. As System Operator, it operates the power system or grid in accordance with the Philippine Grid Code. It is also the country's only utility responsible for transmitting high-voltage power from generators to distributors. NGCP does not own nor operate and maintain any power generation and distribution facilities.
