The Gemini consortium has signed all construction, operations and financing contracts with a total construction budget of nearly $4.1 billion.
With more than 20 parties involved 70 percent of this budget will be provided on the basis of project financing. For the Gemini project Siemens will deliver 150 wind turbines with a capacity of 4 MW and a rotor diameter of 130 meters each.
The wind power plant is to be located in the North Sea, 52 miles above the coast of Groningen. With an installed capacity of 600 MW in total Gemini will yield 2.6 TWh of electricity per year.
The wind power plant will supply clean energy for one and a half million people after being fully commissioned. The amount of energy is equivalent to a reduction in the emission of carbon dioxide by 1,25 million tons per year.
For Siemens this is the first order for an offshore wind power plant in Dutch waters. The innovative service concept banks on the ongoing presence of a service vessel and the steady ground readiness of a helicopter.
Siemens’ 15-year service and maintenance agreement for the Gemini project is the largest service order ever for Siemens Energy Service. It will introduce a highly advanced logistics concept for offshore sites. For the first time, a helicopter will be available for a project at all times and a specially designed, purpose-built service operation vessel (SOV) will be based at the wind farm. To ensure increased turbine availability, maintenance work can be carried out at almost all times irrespective of the weather conditions or wave height.
Northland Power Inc., a Canadian independent power producer is the main shareholder, owning sixty percent of the shares in Gemini. 20 percent are owned by Siemens Financial Services, while smaller stakes belong to Van Oord (10 percent) and HVC (10 percent), a joint venture of 48 Dutch municipalities and six water regulatory authorities.
By supplying one and a half million of Dutch citizens with clean energy, Gemini will play an important role in helping the Government of the Netherlands achieve the targets mandated by the European Union’s Renewable Energy Directive. It implies for the Netherlands to reach a 14 percent share of energy from renewable sources by 2020. Today the Dutch market has an installed wind power capacity of 2.7 GW, thereof 2.45 GW onshore. The offshore target is 4.45 GW to be operational in 2023.
