MHI-Vestas Launches 9.5 MW Offshore Wind Turbine

Mitsubishi-Vestas has launched its massive V164-9.5 MW offshore wind turbine, built on the V164 platform and capable of powering 8,300 U.K. homes. Motivation: lowering cost offshore wind. The design changes within the V164 turbine platform are minimal. One such turbine is already being tested at Burbo Bank Extension Offshore Wind Farm, United Kingdom.

Dimensions: 35-metric-ton, 80-meter blades. Hub height of 105 meters and a tip height of 187 meters. Nacelle 390-metric-ton nacelle, 20 meters long, 8 meters wide and 8 meters high.

Last December, the machine broke a world record for production by a single wind turbine when it produced 216 MWh of power in a 24-hour period. With a Danish kWh electricity price of 9 euro cent and 31 euro cent for private consumers, this is the equivalent of €19,440 c.q. €66,960. With current offshore price of 2 million euro per MW, implying 20 million euro for the V164-9.5 MW, this would mean that 300 days of consumer end price turnover would match the purchase price (not to be confused with payback period of course).

Denmark – Offshore Wind Power Hub

Important Step Taken Towards Energy Hub North Sea

TenneT TSO B.V. (Netherlands), Energinet (Denmark) and TenneT TSO GmbH (Germany) today signed a trilateral agreement for the development of a large renewable European electricity system in the North Sea. This so-called ‘North Sea Wind Power Hub’ has the potential to supply 70 to 100 million Europeans with renewable energy by 2050.

This important step towards a broad consortium was taken in the presence of the European Commissioner for an Energy Union, Maroš Šefčovič. Mel Kroon, CEO of TenneT, and Torben Glar Nielsen, CTO of Energinet, signed an agreement aimed at investigating the feasibility of one or more ‘Power Link Islands’.

TenneT and Energinet, as well as any other parties that want to join, will spend a few years on investigating the details and potential of one or more Power Link Islands. If the TSOs decide to go ahead with the project, a Power Link Island could be developed by approximately 2035

Estimated size: 6.5 km2
Estimated cost: 1.25 billion euro

The island might feature power-to-gas as a storage technique to utilize high volumes of wind generation, said Rasmussen. The North Sea is home to a sophisticated network of gas pipelines, which could help bring wind-generated gas to countries around Europe.

“A part of this work will be to include power-to-gas technology and other storage technologies,” he said. “What, when [and] how much is what we will look into further. It is too early to go into details.”

How Denmark Aims to Run on Clean Energy

Youtube text: Published on 12 dec. 2015
In Denmark, officials have taken strides to minimize the effects of climate change by converting from fossil fuels to renewable energy sources like wind and solar power. Over the next 35 years, the country aspires to become the first nation on earth to run completely, including transportation, on clean energy. NewsHour Special Correspondent Lisa Desai reports.

Construction Started COBRA Cable Netherlands-Denmark

COBRAcable (COpenhagen-BRussels-Amsterdam cable) is a planned 320 kV, 700 MW HVDC submarine power cable between Eemshaven, the Netherlands, and Endrup near Esbjerg, Denmark.

The cable will have a length of 325–350 km, and will be jointly owned by Energinet.dk and TenneT. Its purpose is to improve the European transmission grid and thus to increase the amount of variable wind power in the energy mix while improving the supply security. Its 700 MW capacity corresponds to an annual transmission capacity of 6.1 TWh

[wikipedia.org] – COBRAcable

The capacity of the cable, to be completed in 2019, would be sufficient to power a city like Amsterdam. The construction of the cable is a natural part of the strategy to move towards more renewable energy and the necessity to even out intermittent supply.

Denmark – 116% Electricity Demand Met by Wind

denmark-wind[source] Denmark: 75% onshore, 25% offshore
Last Thursday the wind conditions in Denmark were such that 116% of the wind energy demand could be met in the evening.

denmark-elec

Denmark’s wind energy infrastructure wasn’t even producing (3.77GW) what it could (4.8GW). Excess electricity was exported to Germany, Sweden and Norway.

Denmark aims to generate 50% of its electricity needs by 2020, but could reach that target even earlier: installation of new capacity adds 18% per year.

Editor: other countries like Sweden, Norway and Canada have even higher rates of renewable energy production, but they achieved that with relative easy means: hydro-power thanks to mountainous terrain, where Denmark is completely flat. Denmark is one of the most successful implementer’s of renewable energy in the world.

Connie Hedegaard

Youtube text: Connie Hedegaard, European Commissioner for Climate Action in the European Commission since 10 February 2010, interviewed by CleanTechnica Director Zachary Shahan at Abu Dhabi Sustainability Week, the 6th Annual World Future Energy Summit, the 5th International Renewable Energy Conference, and the 1st International Water Summit in the UAE.

Connie Hedegaard is a Danish conservative politician and European Commissioner for Climate Action since 10 February 2010. She was Danish Minister for Climate and Energy from 23 November 2007. It is her ambition that by the end of her five-year term, Europe will be the most climate friendly region in the world. She is a believer in sustainable economic growth. Since 2007, Connie Hedegaard has been behind Denmark’s energy policies, which made her country the first in the world to commit to an overall energy reduction, not just a reduction in greenhouse gas emissions.

Cash Cow Wind Energy

Roenland_Denmark[source]
In 2010 four windturbines placed near Rønland in NW Denmark were the recordholder in generating energy: 63.2 GWh each since 2003, the year of installation. In market electricity prices at 20 euro cent per kwh, this equals to a yield of 12.6 million euro each to date. Extrapolating this over the total life expectancy of 25 year, this amounts to 45 million euro. These are 2 MW windturbines with an estimated price of 2 million euro, excluding maintenance. In financial terms these figures are fantastic. And after 25 years the cost of the tower and foundation is definitely not written off and they could last centuries, think Eiffel tower, built in 1889. Or this still functioning Dutch windmill, dating from ca. 1630. Expect this record to be broken soon. Considering these figures one cannot escape the conclusion that our energy situation is far from hopeless and that the energy transition is mostly a question of awareness and rethinking old assumptions as well as breaking vested interests of the gas & oil industry.

Denmark 2011 – 40.7% of Electricity Produced Renewable

There can be little doubt that there are no real physical of economic limitations that could prevent several European countries from getting independent from fossil fuel as far as electricity generation is concerned, as early as 2020. Denmark for example produced 40.7% of its electricity from renewable sources in 2011.
