The Philippine DOE has a list of Power Plants on their website here if you click on the “2006 Existing PP” tab at the bottom.
I’ve put that into a spreadsheet that you can have, for free, here.
Why doesn’t DOE provide a spreadsheet? I dunno. They should.
Update: Here is my own list of Philippine Power Plants. I dynamically update this file as I get new information.
Update: Also see this post for another dataset of Philippine power plants produced by CARMA.
