More than 10,000 km2 of windy land area is estimated
to exist with a good-to-excellent wind resource potential. These windy land areas
represent less than 4% of the total land area (299,000 km2) in the Philippines.
Using conservative assumptions of about 7 MW per km2, these windy areas could
support more than 70,000 MW of potential installed capacity, delivering more than
195 billion kWh per year. There are 47 provinces out of 73 in the Philippines
with at least 500 MW of wind potential and 25 provinces with at least 1,000 MW
of wind potential.
However, to assess the wind electric potential
more accurately, additional studies, considering factors such as the existing
transmission grid and accessibility, are required. If we consider additional areas
that have a moderate wind resource potential or that have a good wind resource
for rural power applications, the estimated total land area increases to more
than 25,000 km2 (slightly more than 8% of the total land area of the Philippines).
This land could support over 170,000 MW of potential installed capacity, delivering
361 billion kWh per year. There are 51 provinces out of 73 with at least 1,000
MW of wind potential and 64 provinces with at least 500 MW of wind potential.
