The aim is to boost inter-regional transmission capacity by 11GW by 2020, Moacir Carlos Bertol, planning vice-secretary at the Mines and Energy Ministry, tells Recharge.

The current 5GW transmission capacity between the northeastern and southern regions is increasingly seen as a limiting factor for the construction of new wind projects.  

In addition, Bertol says, the government should hire consultants to determine the maximum amount of wind power that Brazil's 120,00km transmission grid could accommodate without disrupting the country's mostly hydro-thermoelectric power mix.
