The Bangui Windmill in Ilocos is not a result of the Marcos' initiative as they claimed.
Rather, we owed the initiative to the study conducted by the National Renewal Energy Laboratory in 1996.

Wind energy harvesting has two main criteria: (1) Wind energy density (2) Low historical maximum winds.
Wind energy density is usually derived from the wind energy spectrum that was determined using continuous data gathering on different location.
Wind energy density can also be extrapolated (from the synoptic data) from evaluating the wind exposure.

The Bangui bay is situated at the Northwestern End of the Cordilleras. Therefore the location is exposed to both the sustained winds from the northeast (Amihan) and the southwest (Habagat).
Being the open valley along the mountainous shoreline of northern shores of Ilocos Norte, the topography induces a channeling effect (with the valley acting as an opening) resulting to higher wind energy densities up to 30 W/sq.m, ideal for wind turbines.
At the same time, the Cordillera mountain range provides a shielding effect that protects the wind farm from severe winds brought by typhoons by reducing the magnitude.
Typhoons don't normally traverse Northeast at that latitude unless they are on the weakening stage (with the exception of Typhoon Ryan in the 90s). So the area is less likely to experience a full brunt of a strong typhoon. Hence, a lower demand for structural capacity.
This is attested by the Generalized Extreme Value Analysis that projects the maximum wind speed that the location can experience throughout the wind turbines' service lifetime. GEV analysis determined a 100-year winds of 150 kph. The historical maximum is around 170 kph.
Given that this was an attractive business pitch also, the Northwind Power Development Corp. heavily invested on this. And through some international funding and Danish support, the wind mills became operational in 2005.
The Marcoses, who happened to be the ruling political clan there, just did the ribbon cutting ceremony in the day of its inauguration.
And just like the nutribun, the miracle rice, & the other societal/scientific endeavours, the Marcoses shamelessly took the credit of this also.

The same principle applies to the Pililla Wind Frame. The orographic effects along with its exposure on both on its NE (Mabitac portion of Laguna Lake) and SW (Pililla portion of Laguna Lake) sectors made it an ideal place for wind energy harvesting.
On a side note, I was quite thankful that I didn't pursue my first graduate research involving Fluid-Structure Interaction to do Structural Health Monitoring on these turbines. That topic is already on the PhD level na pala.
