What`s the relevancy of ones location to the question at hand? The effects of this power plant are not limited to this particular area, carbon emission is a global problem. I don`t think anybody wants to deprive the people of Mindanao, and other parts of the PI, of their right to electricity>work places>development etc. the question is more about the choice of energy source and location. In this day and age other sources are available which have far less devastating effects on local and global environment and are available in the PI, such as the sun, wind and wave. Why opt for coal which is polluting and has harmful effects (not only when burnt, but when mined, transported as well as in by products: dust in air and dumping of at sea)?
If the building of the power plant is indeed a need and is done for the benefit of the people, then the way to go about it is to look for the best solution for the long run, not for the quick fix. In the long run those poor people will suffer from more lung disease such as asthma, bronchitis and cancer due to emission of particals and gases, despite filtration and what not that is said to bring it down to EU standards. Will they be rich enough to afford medical treatment? I doubt that. One thing for sure, nobody will be able to pull the plug on the plant should the level of pollution be higher then allowed, at most there will be a slap on the wrist and perhaps a fine which the power plant will have no difficulty in paying, the population however will continue to pay with their health. Coral reefs are a resource that can generate income-take a look at the Maldives and see how they turn their reefs into $. True this takes time and it requires peace and stability but it will ensure more income for more people in the long run, and peace and stability are desirable regardless.
Further more, the PI being an island nation has a vested interest in cutting down emissions if it wishes to survive beyond today and tomorrow. Read this:

I hope people and reefs are spared.
