The target was a key election promise by the Labor Government.
An independent panel on Monday handed down 11 recommendations in its the final Roadmap to Renewables report.
The suggestions include making renewable energy a central pillar of the NT Government’s economic policy.
The changes outlined in the plan would see the Territory move away from its reliance on gas and diesel, which accounts for 96 per cent of its energy generation.
This year only 4 per cent of the NT’s energy generation came from solar power.
Chief Minister Michael Gunner said work will begin immediately to increase the Territory’s use of solar power until it was the region’s main energy source.
“The shift to renewable energy is inevitable,” he said.
