Thor Wind Farm I/S has won the concession to build Thor Offshore Wind Farm. This is the first time a tendering procedure has been completed for offshore wind energy in Denmark without aid. When power is produced, the winner is expected to pay DKK 2.8 bn. to the Danish state within just a few years.

Today, the Ministry of Climate, Energy and Utilities briefed the parties to the Energy Agreement that Thor Wind Farm I/S, where stakeholders are RWE AG, RWE Renewables GmbH, RWE Renewables Management UK Limited, has won the concession to build Denmark's hitherto largest offshore wind farm: Thor Offshore Wind Farm. Several bidders offered to build the offshore wind farm with the largest possible capacity and at a minimum price of only 0.01 øre/kWh. Therefore, in accordance with the tender conditions, the tendering procedure was decided by a drawing of lots today.

“The tendering for Thor Offshore Wind Farm is yet another milestone in the history of Danish offshore wind power. For the first time ever, the state must be paid for authorization to establish an offshore wind farm. The competitive price in the tender is even more impressive because, for the first time, the winner bidder will also have to pay for the landing cables and grid connection. This is very promising for future tendering procedures for offshore wind energy and for the green transition,” said the director general of the Danish Energy Agency, Kristoffer Böttzauw.

The draw took place earlier today and was monitored by an independent auditor and the Danish State’s legal advisor to ensure that the draw complied with public procurement terms. Moreover, the bidders for which lots were drawn also took part to ensure full transparency.

The Danish Energy Agency expects to invite the winner of the concession to a meeting very soon to discuss the future process. The Danish Energy Agency expects to sign the concession agreement with Thor Wind Farm I/S within 4-6 weeks.

The successful bidder will pay to build Thor Offshore Wind Farm

It is expected that Thor Offshore Wind Farm will produce electricity from about 2026. With the expected electricity prices, it is anticipated that the winning bidder will have paid the state the DKK 2.8 bn. over very few years, see figure 1. After this, in practice there will be no financial transactions between the state and the winning bidder, and the wind farm will be run on purely commercial terms, without support, for the rest of its anticipated 30-year life.

This means that it is the world’s first offshore wind farm constructed with payments to the state. Another new aspect is that grid connection is included in the bid price (i.e. the offshore transformer substation, including the substation onshore and cables up to the transmission grid in Idomlund).
