PWEI’s shareholders are PGEC (40%), Thailand’s BCPG Public Company Ltd. (40%), and PERC (20%). The first phase (36 MW Nabas-1) of the wind farm was commissioned in June 2015, while, the second phase (14 MW Nabas-2) is still on pre-development phase. Nabas-1 is erected at an elevation of 300-500 in the foothills of northern Aklan making it the country’s highest perched wind farm to date.
