The farm, which will be twice the size of Denmark's current largest, will be put out to tender in 2021 and built between 2024 and 2027. The government has yet to decide on where the farm will be based.
The farm is the most eye-catching scheme in a government proposal published on Thursday, which it hopes will form the basis of a future energy agreement with opposition parties setting the direction for Denmark's energy policy from 2020 to 2030.
"The government's long-term climate target is that Denmark must be a low-emission society by 2050 which does not emit greenhouse gases and is completely independent of fossil fuels such as coal, gas and oil,” Energy Minister Lars Christian Lilleholt said in a press release.
“We must be able to cover at least half of Denmark's energy demand for renewable energy by 2030.”
But the focus on wind generation comes alongside a sharp reduction in electricity taxes, which is unlikely to please environmentalists.
The government hopes to cut the tax on electricity from 91 øre a kilowatt to 25 øre between 2019 and 2025, saving the average family 1500 Danish kroner a year, and also halve the tax on electric heating from 30 øre to 15 øre.
Danish Energy, the country's trade body for energy companies welcomed the plan.
The proposal marks a new departure, where the green goes up, but the electricity bill goes down," the body's chief executive Lars Aagaard said in a press release.
His main criticism was that the government had failed to emphasise transport sufficiently.
“If we want to we achieve our long-term climate ambitions and targets for energy efficiency, we need to consider cars powered by electricity rather than fossil fuels,” he said, pointing out that an electric car is three times as energy efficient.
Pia Olsen Dyhr, chair of the Socialist People's Party, said the government's claim that the proposal was "the greenest in Denmark's history" was “pure gibberish”.
“It is quite clear that it is far more important for the government to provide tax relief than to be be ambitious when it comes to solving the climate challenge and to create jobs in green companies,” she wrote in a blog post.
“I'm deeply afraid that my daughter's going to come and knock on my door in 20 years furious that we did not do more to curb climate change.”
