Hohe See and Albatros
EnBW has started the construction of both wind farms in the North Sea at the same time. They will supply electricity for an aggregate of around 710,000 households from 2019.
Baltic 1
Our EnBW Baltic 1 wind farm is the first commercial offshore wind farm in Germany and has been in operation since April 2011.
Baltic 2
EnBW Baltic 2 was connected to the grid in September 2015. 80 wind turbines produce up to 1.2 billion kilowatt hours of electricity annually.
EnBW Baltic 1: How a wind farm is constructed on the high seas
Preparation: A traffic management ship arrives at the construction site and monitors the traffic at sea. The construction office is procured and the employees gradually commence their work.
Groundbreaking ceremony: official start of construction at sea. The components for the turbines that were manufactured on land are now successively installed at the offshore construction site.
Foundations: The special ship Sea Worker brings the foundations consisting of monopiles and transition pieces to the construction site.
Special ship: The Sea Worker anchors the monopiles, steel foundations around 37 m long, into the seabed using a powerful pile driver.
Colossus: Transition pieces are used to connect the foundations and the wind power plants together.
Transfer: The floating crane Matador (middle) transfers the 430 t monopile for the substation to the installation ship Sea Worker (right).
Precision work: The floating crane has delivered the 900 t substation to the construction site and will place it onto the transition piece in the evening.
Basis: The yellow crowhorn serves as the supporting surface for the substation and is fitted to the transition piece at the construction site.
Cable: Divers guide the sea cable upwards from the seabed through the transition piece. The cable will later be connected to the wind power plant.
Tower construction: The tower for the first wind power plant rises up piece by piece.
Raising the star-shaped rotor: The special crane has mounted the rotor with its 45m long rotor blades to the nacelle.
Precision landing: The first star-shaped rotor has been raised and the first wind power plant is installed.
For now the first turbine stands alone on the high seas...
...but the remaining 20 turbines will also soon be installed – EnBW Baltic 1 has been generating enough electricity for an aggregate of 50.000 households since 2010.
On course for the future
Offshore office in Hamburg: Around 100 employees are involved in planning the EnBW wind farms. This is where expert reports are produced, authorities are consulted and decisions are made. Manufacturers and service providers must be commissioned, transport and delivery chains planned and all processes that make up the highly complex erection work must be coordinated – while possible delays also need to be compensated for.
The station that never sleeps
The service station in Barhöft: It is from here that the wind farm installed at sea is controlled and all the service tasks are coordinated – round the clock, seven days a week. Data about the weather and sea conditions indispensable to the operation of a wind farm are delivered continuously through measurements taken at sea. The offshore turbines switch themselves on from wind force 3 and automatically switch themselves off again in storms from wind force 10.
Wind power today and tomorrow
Our EnBW Baltic 1 wind farm is the first commercial offshore wind farm in Germany and has been in operation since April 2011. It is located 16 km north of the Darß/Zingst peninsula. The 21 wind power plants at EnBW Baltic 1 have a total output of 48.3 MW. They can thus cover the aggregate annual electricity requirements of around 50,000 households, preventing 167,000 t of harmful CO2 being released into the environment.
Our EnBW Baltic 2 wind farm surpasses EnBW Baltic 1 in all its dimensions. The construction of the second offshore project began at the end of 2011. It was officially placed into operation in 2015. The wind farm is located approximately 32 km north of the island of Rügen in the Western Baltic Sea on an area of around 27 square kilometres. EnBW Baltic 2 comprises 80 wind power plants each with a capacity of 3.6 MW and a total capacity of 288 MW. The offshore wind farm generates 1,200 GWh of electricity per year for around 340,000 households.
Following on from the Baltic Sea, EnBW will now take on the North Sea. In cooperation with its Canadian co-investor Enbridge Inc., EnBW will construct this offshore wind farm with a capacity of 497 megawatts around 90 kilometres north of Borkum and 100 kilometres north-west of Helgoland. 71 turbines will be installed on an area covering 42 square kilometres and generate around two billion kilowatt hours of electricity per year. After the wind farm has been commissioned – anticipated in 2019 – it will be able to supply around 560,000 households and save around 1.5 million tonnes of CO₂.
On course for the future with offshore wind power. EnBW aims to move further out to sea with the offshore wind farms planned in the North Sea – Albatros and He Dreiht. The demands relating to the scope, size and environmental conditions increase with every project. That means that the tasks involved are best tackled with years of experience, commitment and an international team of offshore experts – which is what happens at EnBW.
