With Wind Turbines Is It Bigger Are Better?
The offshoreWIND.biz web site has two stories today, with a similar theme.
- Scots Greenlight Slimmed-Down Turbine Plan For 100 MW Pentland Floating Offshore Wind Farm, which described how the Pentland wind farm is reducing the number of turbines from ten to seven, but increasing their size from 10 to 14 MW, to produce the same power output.
- Fred. Olsen Seawind, EDF Slash Turbine Count For Codling Wind Park, described how in the Irish wind farm; Codling wind farm, the number of turbines are being reduced from hundred to seventy-five.
There are also some wind farms, where capacity has the potential to be increased.
- Ossian Floating Wind Farm Could Have Capacity Of 3.6 GW
- Crown Estate Mulls Adding 4 GW Of Capacity From Existing Offshore Wind Projects
Note.
- With the exception of the floating Pentland wind farm, all wind farms have fixed foundations.
- It certainly does look, that larger turbines may have reasons to be used.
- Perhaps installing a large turbine is very much the same as a small turbine.
It looks like a victory for the accountants.
CIP’s Flagship Fund On Track To Become World’s Largest Dedicated To Greenfield Renewable Energy Investments
The title of this post, is the same as that of this article on offshoreWIND.biz.
This is the sub-heading.
Copenhagen Infrastructure Partners (CIP) has reached the first close on its fifth flagship fund, Copenhagen Infrastructure V (CI V), at EUR 5.6 billion in capital commitments received. This puts the fund on track to reach its target size of EUR 12 billion, which would make this the world’s largest dedicated greenfield renewable energy fund, according to CIP
These three paragraphs give more details on the size and investments of the latest fund, which is named CI V.
The first close of the flagship fund saw a large group of leading institutional investors across continental Europe, the Nordics, the UK, North America, and the Asia-Pacific region.
CIP noted that there is a strong interest from additional investors already in process, so CI V is on the way to reaching its target fund size of EUR 12 billion.
The fund now has ownership of more than 40 renewable energy infrastructure projects with a total potential CI V commitment of approximately EUR 20 billion, corresponding to more than 150 per cent of the target fund size.
The CIP web site gives more details on the company, including this summary on the front page.
Founded in 2012, Copenhagen Infrastructure Partners P/S (CIP) today is the world’s largest dedicated fund manager within greenfield renewable energy investments and a global leader in offshore wind. The funds managed by CIP focuses on investments in offshore and onshore wind, solar PV, biomass and energy-from-waste, transmission and distribution, reserve capacity, storage, advanced bioenergy, and Power-to-X.
CIP manages 11 funds and has to date raised approximately EUR 25 billion for investments in energy and associated infrastructure from more than 150 international institutional investors.
In the UK, CIP are currently involved in the Ossian and Pentland floating wind farms.
100 MW Scottish Floating Wind Project To Deliver Lifetime Expenditure Of GBP 419 Million
The title of this post, is the same as that of this article on offshoreWIND.biz.
This is the sub heading, that gives more details on lifetime expenditure and full-time equivalent (FTE) jobs created.
The 100 MW Pentland Floating Offshore Wind Farm in Scotland is estimated to deliver lifetime expenditure of GBP 419 million in the UK and to support the creation of up to 1,385 full-time equivalent (FTE) jobs.
It does seem these figures have been compiled using the rules that will apply to all ScotWind leases and have used methods laid down by Crown Estate Scotland. So they should be representative!
Does it mean that a 1 GW floating wind farm would have a lifetime expenditure of £4.19 billion and create 13, 850 full-time equivalent (FTE) jobs?
This article from Reuters is entitled UK Grid Reforms Critical To Hitting Offshore Wind Targets and contains this paragraph.
The government aims to increase offshore wind capacity from 11 GW in 2021 to 50 GW by 2030, requiring huge investment in onshore and offshore infrastructure in England, Wales and Scotland.
If I assume that of the extra 39 GW, half has fixed foundations and half will float, that means that there will be 19.5 GW of new floating wind.
Will that mean £81.7 billion of lifetime expenditure and 270,075 full-time equivalent (FTE) jobs?
Conclusion
It does seem to me, that building floating offshore wind farms is a good way to bring in investment and create full time jobs.
CIP Picks Stiesdal Floater For 100MW Scottish Offshore Wind Farm
The title of this post, is the same as that of this article on Offshore Engineering.
These two paragraphs introduce the project.
Copenhagen Infrastructure Partners (CIP) has selected Stiesdal Offshore’s TetraSub floating foundation structure for the 100MW Pentland Floating Offshore Wind Farm project, to be located off the coast of Dounreay, Caithness, Scotland.
The technology has been said to offer a lightweight and cost-effective floating solution, based on factory-made modules which are then assembled domestically in port to form a complete foundation.
Note.
- The TetraSub seems to have been designed for ease of manufacture.
- One if the aims appears to be to build a strong local supply chain.
- The TetraSub was designed with the help of Edinburgh University.
- The TetraSpar Demonstrator is in operation off the coast of Norway.
- This page on Mission Innovation describes the TetraSpar in detail.
- The TetraSpar foundation, owned by Shell, TEPCO RP, RWE, and Stiesdal.
- It can be deployed in water with a depth of up to 200 metres.
- Currently, they carry a 3.6 MW turbine.
- At that size, they’d need 27 or 28 turbines to create a 100 MW wind farm.
The home page of the Pentland Offshore Wind Farm gives more details.
This article on offshoreWIND.biz is entitled CIP And Hexicon To Halve Pentland Floating Wind Project Area.
- The project area has been halved.
- The number of turbines has been reduced from ten to seven.
- Compact turbines will be used.
- The project will be built in two phases, one turbine in 2025 and six in 2026.
- Effectively, the first turbine will help to fund the second phase, which eases cash flow.
The changes show how the wind farm has changed during development due to local pressures and improved technology.
Conclusion
It does seem that the competition is growing in the field of floating wind turbines.
Given the quality of the research and backing for these floats and the fact they now have an order, I wouldn’t be surprised to see this technology be a success.
