Power Shortage in Mindanao: A Call for New Power Plants

It is swirling in the news that Mindanao suffers from power shortage. According to the news aired on March 27, 2012 over GMA News' Saksi, The Energy Department had said that projected peak demand in Mindanao is 1,300 MW although the available capacity is only at 1,100 MW, excluding the required reserve margin to maintain the "integrity" of the Mindanao Grid which is pegged at 250 MW. The same television report said the power shortage was reportedly caused by the lack of electricity being produced by the hydro electrical power plants in Mindanao due to heat brought by the dry season. "Considering the future lower rainfall forecast in Mindanao, we cannot rely solely on hydropower plants. Non-hydro base-load is immediately needed and this will only happen if everyone cooperates,” Energy Secretary Jose Rene Almendras said.

According to the DOE's Mindanao Field Office curtailment schedule obtained by GMA News Online on March 28, 2012, some parts of Region IX, X, XI, XII, and XIII have recently been experiencing rotational brownouts. Among these areas are: Pagadian City, Zamboanga del Sur (4 hrs/day), Zamboanga City (4 hrs/day), Maramag, Bukidnon (1 hr/day), Iligan City, Lanao del Norte (2.5 hrs/day), Marawi City, Lanao del Sur (3.5 hrs/day), Tubod, Lanao del Norte (3 hrs/day), Ozamis City, Misamis Occidental (3 hrs/day), Calamba, Misamis Occidental (5 hrs/day), Digos City, Davao del Sur (3 hrs/day), Tagum City, Davao Norte (1.5 hrs/day), Tacurong City, Sultan Kudarat (1 hr/day), Kidapawan City (4.32 hrs/day), Datu Odin Sinsuat, Maguindanao (4 hrs/day), General Santos City, South Cotabato (4 hrs./day), Koronadal City, South Cotabato (1 hr/day), Surigao City, Surigao del Norte (4 hrs/day), Siargao, Surigao del Norte (3 hrs/day), Tandag, Surigao del Sur (1 hr/day), San Francisco, Agusan del Sur (2 hrs/day).

Last August 7, 2012, parts of Mindanao have suffered power supply interruptions anew as the island’s already-insufficient generation capacity has been eroded by emergency repair and preventive maintenance work on some plants. |

As of August 8, 2012, Milfrance Q. Capulong, National Grid Corporation of the Philippines (NGCP) corporate communications officer for Mindanao, said the island’s power situation is back to "red alert" status, indicating severe deficiency in supply.

Santiago C. Tudio, South Cotabato Electric Cooperative 1 (Socoteco-1) manager, said "The brownouts that we’re experiencing would continue unless new power plants would rise".

Coal-Fired Power Plant in Davao City
An analysis written in April 10, 2012 reports that electricity users in power-strapped Mindanao are up in arms against government plans to build more coal-fired plants to relieve the critical energy shortage, warning that these would lock the island into a polluting source of power. The warning was sounded ahead of the energy summit in Davao City at the weekend by the environmentalist foundation, Greenpeace Southeast Asia, which claimed that contracts had been prepared to allow the construction of coal plants which are reported to be “more expensive, dirty, and nonrenewable power.” (Retrieved September 16, 2012 from http://opinion.inquirer.net/26509/mindanao-power-shortage-remains-grim)

How Coal Power Plant Produce Electricity

The conversion from coal to electricity takes place in three stages. Stage 1
Conversion of energy takes place in the boiler. Coal is burnt in the boiler furnace to produce heat. Carbon in the coal and Oxygen in the air combine to produce Carbon Dioxide and heat. Stage 2
The second stage is the thermodynamic process.
1. The heat from combustion of the...
