Brazil’s upper legislative house has approved the first regulatory guidelines needed to allow the country to tender blocks for the construction of offshore wind projects.

A bill was approved in the Senate this week but still needs approval in the Lower House, where debates are expected to start in the new year.

Discussions over offshore development began in late 2016 but have divided opinion in the country.

Local wind industry body ABEEólica says that it’s too early to expect serious investment in offshore wind, since Brazil has only explored 14GW of its 200GW-plus cheap onshore wind potential.
