Zamboanga City needs additional source of energy whether people like it or not.

Thus stressed Councilor Benjamin “ Nonong” Guingona as he explained that the city is growing fast, with the population constantly increasing and business activities becoming more active, hence the demand for power is going up.

Guingona, who sits as board member at the Zamboanga City Ecozone, said he is in favor of the coal-fired power plant being put up by Conal Holdings because it is an immediate solution to the looming power shortage in Zamboanga City and in all other parts of Mindanao.

According to Guingona, Zamboanga Ecozone needs additional  source of  electricity because investors need stable electricity and  security for their investment.

He however pointed out that Conal  (San Ramon Power Inc.) must pass all the requirements put up by the Department of Environment and Natural Resources for the safety and protection of the environment and the people.

Guingona expressed belief that the coal power plant of SRPI is not dangerous to the health of the people and to the environment because it uses coal mineral.

He said there are cities in Luzon that have coal-fired power plants and there has been no reports of health hazard to the people and environment thereat.   
Meanwhile,  Dipolog City Mayor Evelyn Uy, who is the Regional Development  Council 9 Chairman disclosed that  in the year 2015, there will no longer be power shortage in Mindanao.

Zamboanga City  Electric Cooperative OIC Manager Engr. Jesus Castro also confirmed lin the ast  two months of 2011, Mindanao experience  power shortage.
He said that Mindanao needs 900 megawatts of power and the Maria Cristina grid now unstable.

Castro said the Lanao grid It can no longer provide an emission of 900 megawatts. It can only provide some 700 megawatts of power.

In a related development, the Mindanao grid remains on “yellow alert” as of Saturday as power supply reserve in the island dropped due to ongoing maintenance shutdown operations by the producers, a company official said.

Milfrance Q. Capulong, National Grid Corp. of the Philippines (NGCP) corporate communications officer for Mindanao, said they were not advised when the maintenance operations would end that would allow the return of sufficient reserve for the island.

“We’re still on “yellow alert” with the reserve power supply becoming thinner,” she said in a phone interview.

A yellow alert is a system condition where the total of all reserves is less than 13.2% of the required capacity. When system reserves are more than sufficient to meet the reserve requirements of the grid, the system is considered to be under normal condition. The system alert, and the corresponding power curtailment, if any, is lifted once demand recedes or once there is enough available capacity coming into the grid from the power plants.

As of the 6 a.m. Saturday, power situation outlook of the NGCP, Mindanao’s system capacity stood at 1,267 megawatts (MW) with a system peak load of 1,181 MW, or a reserve of only 86 MW.

In  last Monday’s NGCP power outlook, the system capacity of the Mindanao grid was at 1,276 MW, with a peak load of 1,067 MW, or a reserve of 209 MW.
NGCP is the private operator of the country’s transmission network.

During periods of generation deficiency, NGCP implements the Mindanao grid-wide power load curtailment to maintain the power grid’s security and reliability.

“It is NGCP’s obligation under the law and its franchise to ensure that the grid operates at an optimum level with due consideration for safety, security and reliability,” NGCP spokesperson Cynthia Perez-Alabanza said in an earlier statement.

The level of curtailment is based on the Mindanao generation deficiency matrix issued to the NGCP by the Power Sector Assets and Liabilities Management (PSALM) Corp and the National Power Corp (NPC), Alabanza said.

The NGCP does not, by itself, determine which franchise area or distribution utility gets what portion of the available supply, she said, adding they only follow the matrix supplied to them by PSALM/ NPC.

Beginning October 19, NGCP implemented load curtailment based on PSALM/ NPC’s matrix when available reserve energy levels dropped to negative 12MW, and persisted until October 24 when reserves were at negative 45MW, according to Alabanza.

Owing to the negative reserves attributed to the scheduled maintenance of some power plants, and the unexpected shutdown or reduced capability of others, the NGCP had declared a series of “red alerts” in the Mindanao grid.

“Red alert” refers to the system condition when the contingency reserve is zero or a generation deficiency exists

“Grid conditions improved to a yellow alert status on October 25, the day one of the plants on scheduled maintenance went back online. Still, the reduced capability of other plants led to a situation where the available reserves were insufficient to meet the grid’s required contingency,” Alabanza said. — Allen Abastillas  with report from Bong Sarmiento/MindaNews
