Global Wind Energy & Infrastructure, page-47

Same here @wenty. I did a little analysis on the Ishikari Wind Project using the figures provided in this previous post Post #: 65129339.
Again ran 3 possible scenarios just for the wind turbines excluding the battery storage aspect.
1. Conservative = 1,233 tonnes Cu
2. Median = 1,580 tonnes Cu
3. Bullish = 2,196 tonnes Cu

This is the turbine to be used at Ishikira.

Several sites state the optimum spacing is set between 8 and 12 times the rotor diameter in the direction of the wind, and between 2 and 4 times in the direction perpendicular to the wind. You could used this graph as a guideline for future calculations perhaps.
For simplicity, I used side by side in one row for the calculations as it is a shorter cable distance but could well be 2 rows of 7 so the cable distance would be slightly longer.
