Project boss Matthias Haag announced last night the 54-turbine wind farm would restart construction this week.
Located off Scotland’s east coast, it was awarded a Contract for Difference (CfD) in 2015 and will look to generate enough energy to power 375,000 homes.
It is expected to create around 500 jobs while also delivering £540 million to the local economy.
Mr Haag, NnG project director, said the wind farm build would resume with a small, staggered workforce return in line social distancing rules.
He added: “Initially, we will only have a few people on site to put in place control measures so the rest of the team can start work safely later that week.
“Once that’s happened we will have a reduced workforce on site, including essential supervisory staff.
“The arrangements we have put in place will be under regular review as we continue to closely monitor Covid-19 and follow the Scottish Government’s guidance.”
NnG wind farm, a 54-turbine projects, was due to begin full offshore construction in June 2020 before the Covid-19 outbreak.
EDF Renewables sold half of the NnG project to Irish firm ESB in November last year.
The first initial payment was understood to be around £50 million.
