Dutch Wind Energy Installation Data

Dutch onshore wind capacity grew with 94 MW in 2018.
Dutch wind installation 31-12-2018:

Offshore: 0.957 GW
Onshore: 2.647 GW
Total: 4.130 GW

Goal 2020: 6.0 GW

Note these figures are nameplate (max values).
Average Dutch electricity consumption: 13 GW

The green bars indicate which part of the 2020-target has been realized. The Zeeland province is almost there, Drenthe is lagging behind.

– Offshore windparks Borssele I&II (750 MW) are expected to come online in 2020, Borssele III&IV (750 MW) in 2021.
– Offshore windparks Hollandse Kust Zuid I&II (750 MW) are expected to be completed in 2022.
– After that Hollandse Kust III&IV (750 MW) and Hollandse Kust Noord I&II (750 MW) are next, no closed tenders yet.
– Between 2024-2030 IJmuiden Ver (4 GW) will be next. After 2030, massive expansion further North up until the Doggerbank is definitely an option, enabling the Netherlands to become an energy exporter once again.

By that time storage and energy island will need to be taken into consideration, like a pumped-hydro facility at the Doggerbank and hydrogen electrolysis (cost half a cent per kWh renewable electricity, resulting in a price of stored chemical energy of ca. 6 cent/kWh).

Currently renewable electricity in the Netherlands from solar is 20% of that of wind.

Shell Plans Return to UK Offshore Wind

Royal Dutch Shell says it is considering bidding for rights to develop offshore wind farms in UK waters as the British-Dutch oil and gas giant seeks to re-enter the nation’s sector after a 10-year absence.

Dorine Bosman, Shell’s wind chief, said the company was interested in seabed leases due to be awarded during 2019 by the Crown Estate, which controls Britain’s coast. The Dutch-based firm left the UK offshore wind sector when it sold its stake in the London Array project 10 years ago.

A global pioneer in the field, the UK was one of the key offshore wind markets Shell wanted to enter, she said. The oil major says it is investing US$2 billion a year in developing “new energies” or low-carbon power.

Shell co-owns a minor offshore wind farm in the Netherlands and a larger Dutch project which is under construction. In December it spent US$175 million entering the tiny US market, acquiring the rights to New Jersey and Massachusetts seabed leases that could potentially generate 4.1 gigawatts of wind power.

[] – Offshore Wind Energy Roadmap 2030 (2018)

Ministerie van Economische Zaken en Klimaat

Subject: Offshore Wind Energy Roadmap 2030

Dear Madam President,

The Dutch North Sea has the potential to play a significant role in achieving the national contribution to the goals of the Paris climate agreement and the necessary sustainable development of our energy supply towards 2050. A number of crucial steps toward achieving this were set out in the Energy Agreement of 2013.1 The basis for the Netherlands’ long-term energy policy was laid down in the Energy Report,2 the subsequent Energy Dialogue3 and the Energy Agenda.4 In the Coalition Agreement, the Dutch Government will continue to develop that policy and will be actively pursuing the implementation thereof.

The current realisation of offshore wind energy under the Energy Agreement has seen and, until 2023, will continue to see crucial steps being taken for the sustainable development of the Dutch energy supply. The prospect of five calls for tender has given market participants the confidence to invest and has altered risk perception. This has resulted in a major reduction in costs. The Government wishes to retain the market’s confidence and the current momentum and intends to issue the remaining calls for tender for the Energy Agreement within the next two years to complete the Offshore Wind Energy Roadmap 2023.5

At the same time, the national government wishes to take the next step to further develop offshore wind energy for the period 2024 to 2030, and wishes to kick off preparations for this endeavour. To that end, this letter contains the key elements for an Offshore Wind Energy Roadmap for the period 2024 to 2030. In this way, I am honouring the commitment I made to the House during the General Consultation on Energy of 18 January.6

Prof. Gorden Hughes At It Again

Prof. Gorden Hughes has launched his usual attacks against the wind industry again:

The report’s author, Prof Gordon Hughes, an economist at Edinburgh University and a former energy adviser to the World Bank, discovered that the “load factor” — the efficiency rating of a turbine based on the percentage of electricity it actually produces compared with its theoretical maximum — is reduced from 24 per cent in the first 12 months of operation to just 11 per cent after 15 years.

Unleashing Europe’s Offshore Wind Potential 2030

The three major European offshore wind zones: North Sea, Atlantic and Baltic.

From the report conclusions:

  • Offshore wind is expected to produce 7% to 11% of the EU’s electricity demand by 2030.
  • Offshore wind could in theory generate between 2,600 TWh and 6,000 TWh per year at a competitive cost – €65/MWh or below.
  • 25% of the EU’s electricity demand could, in theory, be met by offshore wind energy at an average of €54/MWh in the most favourable locations.

Baseline scenario: in the coming decade the British, Dutch, Germans and French (in that order) will be the largest installers of new offshore wind capacity.

Likewise, upside scenario.

2030 projected installed offshore wind capacity per country (baseline and upside scenarios).

European Wind Industry Energy Scenarios for 2030

Compare the (nameplate [*]) figures below with the current average EU electricity consumption of 300 GW.

EWEA’s new Central Scenario expects 320 GW of wind energy capacity to be installed in the EU in 2030, 254 GW of onshore wind and 66 GW of offshore wind. That would be more than twice as much as the installed capacity in 2014 (129 GW) and an increase of two thirds from the expected capacity installed in 2020 (192 GW).

Wind energy will produce 778 TWh of electricity, equal to 24.4% of the EU’s electricity demand. The wind energy industry will provide over 334,000 direct and indirect jobs in the EU and wind energy installations in 2030 will be worth €474 bn. The 96,000 wind turbines installed on land and in the sea will avoid the emission of 436 million of tonnes (Mt) of CO2. EWEA’s Low Scenario only foresees 251 GW of wind energy installations, 22% lower than in the Central Scenario, equal to meet 19% of EU electricity demand in 2030. Such level of installations would mean 307,000 jobs in the wind energy sector, €367 bn worth of investments, 339 Mt of CO2 emissions avoided and 76,000 wind turbines installed and connected to the grid in 2030. The High Scenario expects 392 GW installed in 2030, 23% higher than in the Central Scenario, equal to meet 31% of EU electricity demand. 366,000 jobs will be generated, as well as €591 bn of investments, 554 Mt of CO2 emissions would be avoided and 114,000 wind turbines generating electricity in the EU would be installed.

[*] – “Nameplate power” is the power value the manufacturer associates with his product.

Wind: a 5 MW offshore wind turbine means that under optimal conditions the turbines can generate 5 MW. In reality the conditions are seldom optimal. In case of wind power the bridge between ideal and reality is formed by the concept of “capacity factor“. Currently for North Sea offshore wind, for 5-6 MW turbines, that capacity factor is ca 0.5. For very large 15-20 MW turbines that factor is expected to level off at 0.65 or 65%. In other words, a 5 MW turbine in the North Sea generates 0.5 x 5 MW = 2.5 MW on average (24/7/365).

Solar: standard solar panels of 100 cm x 160 cm can have nameplate 300 Watt. That means that if you put one in the Sahara, on a usually very bright day, tilted towards the sun, you can expect the panel to generate 300 Watt. In countries with mediocre solar conditions, like Holland, the reality is far less rosy. As a rule of thumb, if you want to know how many kWh’s this 300 Watt panel will produce over a year, multiply the peak-Watt value (300 Watt) with an experience factor of 0.85, to arrive at the kWh’s your 300 Watt panel will produce over a year: 300 x 0.85 = 255 kWh. And since a year has 365 x 24 = 8760 hours, the average power your proud “300 Watt panel” will generate 255,000 Wh/8760h = 29 Watt on average (24/7/365).

Prejudices From Amateurs Against Wind Energy


A self-described energy-skeptic & doomer named Alice, who believes that oil can’t be replaced by renewable energy, took the trouble of formulating 41 bold assertions (therefor below in bold), explaining why this would be the case. Every assertion is accompanied by our rebuttals. Judging by the date of the oldest comment, the original blog post was probably written in 2011. A lot has happened since on the wind energy front.

Sneak preview: oil can very well be replaced by 100% renewable energy.

[] – 41 Reasons why wind power can not replace fossil fuels

1. Windmills require petroleum every single step of their life cycle. If they can’t replicate themselves using wind turbine generated electricity, they are not sustainable

Chicken-and-egg story. While it is true that in the initial phase of the energy transition, new wind turbines are by necessity build using fossil fuel, there is no reason why the job can’t be done with energy from wind turbines. In fact, already today most scrap metal is being processed in so-called electric arc furnaces, that run on electricity and thus could be powered by renewable electricity. Furthermore, in a drive to bring down CO2-emission, the Swedish government, among others, is funding efforts to develop steel production without fossil fuels. But even if this would fail, the world gets ever more saturated with iron that can be recycled indefinitely in electric arc furnaces, with ever lower demand for fossil fuel.

20 MW Wind Turbines Are The Limit, Says Industry


Industry leaders presenting at the Global Wind Summit in Hamburg in September described the development of offshore wind turbines that could soon be far larger than existing marques and said they see few technical barriers to developing units as large as 20 MW, with rotors of up to 240 m in diameter… The market will see 15-20-MW turbines by 2030 and highlighted the cost reduction potential of 12-15-MW units already under development… Mr Korsgaard went on to say that a 20-MW turbine with a 250-m rotor diameter is “perfectly feasible” and presented a slide showing a graph of the growth in blade length. The growth curve went all the way up to 140 m… Better quality, faster-to-produce blades could result from a R&D project led by Fraunhofer IWES in Germany. It heads a 14-member industry team that has launched a project that aims to find ways to produce blades for wind turbines more quickly and to higher quality standards.

Tenders Windpark IJmuiden Ver

Timeline Dutch offshore wind. Red-already operational. Blue-tenders accepted in 2023. Green-tenders accepted in 2030.

The Dutch government intends to increase the speed of the roll-out of offshore wind, simply because it can afford to do so, since the financial markets and offshore industry are willing to build new capacity without subsidy, as long as they are guaranteed to be allowed to bring offshore wind electricity onshore and compete with other suppliers, greatly benefiting from the Paris climate Accords. In contrast to what the map says, the tender for 4 GW located in IJmuiden Ver is expected to be inked by 2023, not 2030. That would be 60% of the 2024-2030 ambition. Government CPB (Dutch Central Planning Agency) scenario’s for offshore wind development project up to 75 GW in the Dutch part of the North Sea in 2050. Assuming a capacity factor for large (12 MW) turbines of 0.65, this would imply 50 GW on average. Current average Dutch electricity consumption is merely 13 GW. 25 GW would suffice to power the entire Dutch economy, including heat-pump-based space heating and electrified transport, leaving 25 GW for export.

It could very well be that the bottle neck of the roll out will be timely installation of sufficient storage facilities, although for some time to come, excess electricity could be pumped into the European grid.

The ambition is to install 11.5 GW before 2030:
