You're welcome and I've contacted don-vip too.
He's the power generation refinement proposal author and maybe he would
accept to re-vote it.

I agree with you, all stuff below 50 kV is dedicated to local distribution
in many coutries.
It's difficult to be completly consistent with all that differences.

Could we merge the two proposals power transmission and power generation
refinement and improve the whole model?

power line vs cable is still as important as substations' discussion and
need a definitive answer too.

+1 again.
