The site, located 22.2km off the Dutch coast, will require €1.5 billion in investment from Vattenfall, the developer said. It comprises two 350MW projects, due online in 2022.
The Netherlands Enterprise Agency received four applications from Statoil, Innogy and Witwind (a consortium off Van Oord, Eneco and Mitsubishi subsidiary Diamond Generating Europe), to develop the site without subsidy, according to a government spokesman.
Transmission costs for the project are not included.
"Thanks to drastically lower costs, offshore wind farms are now being constructed without subsidy. This allows us to keep the energy transition affordable," Dutch minister of economic affairs and climate policy Eric Wiebes said.
"Innovation and competition are making sustainable energy cheaper and cheaper, and much faster than expected too."
Following the zero-subsidy bids entered in Germany in May 2017 — won by Ørsted (then Dong Energy) and EnBW — the Dutch government offered the Hollandse Kust Zuid site to developers wanting to build the site without subsidy, prior to going through an auction process.
The German zero-subsidy sites are not due online until 2024.
As price was not a factor in the tender decision, the Dutch government had several other criteria to judge the bids.
All the developers met the initial criteria for technical and economical feasibility, financial, and construction deadline.
Then the government assessed the bids on the experience of the bidders, the quality of the project design, the capacity of the project and the social costs, with added wieght given to the quality of the survey, risk analysis and mitigation measures, according to the Dutch government.
The Witwind consortium, along with oil and gas giant Shell, won the second Dutch offshore wind tender, for the 700MW Borssele III and IV projects. It is won the site with a bid of €54.50/MW in December 2016.
Notable offshore wind players missing in the latest tender include offshore wind leader Ørsted, German firm EnBW and Spanish utility Iberdrola.
"This is excellent news for Vattenfall and the Netherlands. It is a significant step for us in view of our ambitions to grow in renewable energy production," said Vattenfall CEO Magnus Hall.
"The Netherlands is an important market for us and this will be our second offshore project there. It's a great honour for us to get the opportunity to contribute with this project to the transformation of the Dutch energy system.
In 2016, Vattenfall won the Danish offshore projects Vesterhav Syd & Nord and Kriegers Flak at incredibly low bids of €63.80/MWh and €49.90/MWh, respectively. In November 2017, Vattenfall ordered 72 of Siemens Gamesa Renewable Energy's new SG 8.0-167 DD 8MW turbine to be used at the sites.
Vattenfall's senior vice president and head of the wind business unit, Gunnar Groebler added: "Winning the bid for Hollandse Kust Zuid is a result of our continuous cost reduction efforts along our entire value chain and the solid track record and portfolio approach of our company."
Earlier today, Vattenfall announced 1,500 job cuts across the company's operations. The losses will be made in communications, finance and human resources departments and will not affect the running of the business, a spokesman for the group said.

WindEurope CEO Giles Dickson welcomed the announcement: "This news shows zero-subsidy bids are possible for some developers in some markets not least where Governments take on and manage a share of the project risk.
"In this instance the Dutch Government taking care of the grid connection is a significant factor. Plus the Dutch Government has successfully minimised the risk linked to offshore wind by giving clear visibility about future market volumes.
"And the new Dutch Government has committed to bring in a carbon floor price at national level which will help the business case for offshore wind.
"Wind energy is showing again and again that it can deliver ever more capacity for less cash. That's the key message other governments should take from this: they should revise their ambition upwards in their national energy plans and offshore wind is a great way to help them do this," Dickson said.
The Dutch wind energy association, NWEA, meanwhile, said the move to subsidy-free tenders will encourage greater technological evolution.
"Now that we have arrived.. in an era of subsidy free tenders, qualitative criteria have been decisive in the evaluation of the bids," said NWEA chairman Hans Timmers.
"This is an important driver for cost efficiency, innovation, stakeholder involvement and the protection of the environment. In addition, NWEA is closely involved in the roadmap and adapted legislation for wind energy at sea, with which we can take important steps to strengthen the sector.
"It is important that the government continues to focus on ambitious targets for the generation of renewable energy by wind.
"The current negotiations on the new Climate Agreement are essential to give the energy transition even more concrete shape and to support and further develop the Dutch wind sector," Timmers said.
