Windy Wednesday: The Supergrid

From SolarFeeds.com, 2013. Link below.

NOTE: Images here are impressions of a European supergrid rather than actual plans though they do tend to plot the same routes. I suspect Brexit is the only event to have changed some of the options. I am not sure there’s a concrete plan, rather I imagine the grid will progress depending on planning opportunities

Here’s a little on what I’ve learned since last Saturday’s post on the interconnector between Ireland and France. It is real and not only that, it is part of a supergrid that was first mooted at least 20 years ago. It seems to be an accepted fact in the wind energy world because the very reason for the existence of a supergrid is to offset the unpredictability of the wind, to make it feasible. When the wind is blowing here others benefit, when it’s not, then we get our power from elsewhere. But as pointed out here, the amount and size of wind farms planned for little old Ireland as opposed to big old France, for instance, tell a different story. As a friend said to me…

“I would eat all my hats if we get anything flowing this way down the cable.”

And that’s the crux of the problem, it’s not wind energy or development per se – many of us I am sure are pragmatic enough to know we have to make sacrifices – but we just don’t have anyone to tell us what’s going on or what we have to give up. As a community we have no agency at all.

Re: wind energy, you might, like me, at this point, start to ask why billions upon billions of euros/dollars/pounds and decades of effort have been invested in wind energy – which needs a utopian electric grid to operate properly – instead of for instance the tide – which reliably comes in and out twice a day. I imagine it has something to do with lack of imagination (windmills ain’t new) and the human propensity for building big phallic objects. (The tide people are working away, by the way, but seem to be moving slowly because they are worried about chopping up animals with their underwater turbines. I like them already…)

Anyhoo, this supergrid – and others like it – would connect multiple countries by high voltage cables underwater. High voltage because it’s the only way to keep the power current (as it were) and underwater because it has proved too difficult to build them on land because of borders, politics, and because pesky people don’t like them and object. The good thing about planning out in the sea is that, and I quote…

Even though it is technically new, it [the supergrid] can be done without seeking planning permission from anybody apart from the Government, a Government who has already demonstrated strong commitment to offshore wind.”

This is from a 2013 blog post from a company called Mainstream Renewable Power. I don’t think they have much to do with our projects – yet – but they have been working in Africa and Chile, both developing countries/continents and have an ISO certification for Ireland. Interesting that. Maybe we are we third-world now? Something else they didn’t tell us.

‘Looks like we’re surrounded..’From Super Node. A projection of a 2050 electrical Utopia. Link below.

But the political problems that came with an onshore grid still exist with the offshore grid: who runs it/pays for it/benefits from it/maintains it? I suspect the Green Party has a Mary Poppins/Coca Cola ad ideal of us all sharing the load. If we shoot for the moon we may end up among the stars, right? Except that the ‘stars’ most of us will end up among will be gigantic turbines while marine life may be seeing different types of stars. Real-life experience of the world in general and distrust of Irish governance in particular, suggests something disastrous this way comes.

So. The planned wind farms here on the Waterford coast are part of a huge, global project made up of many different elements. Few perhaps can see how it will all pan out, but some, the developers, for instance, have a good enough idea of what’s in progress, politically and scientifically, to take a gamble.

What we need – what we needed – is a strong government to speak for us and also tell us what’s going on. Oh for some Direct Democracy! Referenda should be obligatory for decisions on infrastructure. We should have been kept in the loop and we weren’t and now it may be too late to stop a lot of this. But it’s not too late to influence the location of these developments – as the French did at Mont St. Michel – or to ask questions…

Why build more wind farms than we need here? How can this be an optimal location with a small population and all the wind farms being ‘of necessity’ planned so close to shore? Is the offering up of our immediate coastline a cost-saving exercise to attract developers to a non-optimal site? Why are developers telling us our power won’t go to other countries when that’s been the plan all along? Why develop a plan for 100s of turbines in a UNESCO heritage area to help power communities that refused to have their UNESCO heritage areas blighted by 3 turbines (Mont St. Michel, 2012)? Why don’t the people we elected tell us what is happening here?… and any other questions you can think of for yourself.

It would be good to be told exactly what this will cost us.

The Green Party is having an information session on wind this evening, Wednesday, November 16th, 2021, at the Park Hotel in Dungarvan Co.Waterford at 7:30pm.

Next post is Saturday

Waterford Wind Farms to power Europe?

Did that get your attention? Yes, Eirgrid are planning a 500 metre wide 500km cable route (35km in Irish coastal waters) to France from Youghal for which they are going to pay two-thirds of the cost (after grant aid), with one-third being paid by France. It is usual for the cost, but not the profit, to be passed on to the end-user. From Eirgrid’s application…

“The proposed Celtic Interconnector, which is the subject of this Foreshore Licence Application, involves the pre-lay installation works, cable installation works, operation, and periodic maintenance of a submarine electricity interconnector between Ireland and France.”

The cable will have a life span of 40 years. Thats’s twice as long as the life span of the turbines.

The path of the planned connector plus the 7 wind farms planned for the Waterford and Cork coasts (total 5600 MW)and the two planned for the coast of Brittany (total 800MW)

This project has been underway since 2019 – planned since 2011 – with 4 or 6 public consultations taking place in east Cork where the cable makes landfall. There seem to have been no consultations with the larger community of the south or southeast, for whom the implications of this, when taken together with the other planned developments, are fairly massive. And what are the implications?

  • Well it looks like much of the wind farm development planned for our coast may be for private profit. They, the wind farms, are set to produce far more than we need and this interconnector cable will allow our (very) near shore proposed wind farms to power France and by extension, the landmass of Europe.
  • While the landfall at Youghal may have impacts on the beaches, the rivers Nore and Barrow and Blackwater, including the estuary, Capel Island and Knockadoon Head Nature Reserve, Ardmore and Ardmore Head among other areas that’s just the landfall end of the 500km cable. We know already that invasive surveying needs to take place for cable laying and this could be anywhere from 1km to 4km wide along the whole 500km route. And of course there’s the impacts of the 6 or 7 other windfarms, the survey of those areas and their 12 possible cable routes.

The French Connection will theoretically work both ways – i.e. we can get power from France too. But along the 2,700 kilometers coast of Brittany, which has a population of nearly 5 million, there are only two wind farms proposed: the Saint-Brieuc wind farm, 16km offshore, which, when it becomes operational in 2023, will have a total capacity of 496 MW, capable of powering 835,000 homes and a floating 270MW (max) wind farm planned for the south coast of Brittany. As Waterford and Cork counties have a combined population of 600,000, while the seven proposed farms have an output of 5600 MW (5.6 GW) it is likely then most of the power will be heading one way only: from Ireland to France. This is, incidentally, why we are paying the lion’s share of the cost for the cable – because we supposedly get the profits from the sale of our power. I suspect the profit won’t make it as far as the end-user even though the cost will.

Eirgrid’s proposed cable link making landfall at Youghal, is currently in planning stages. It is part of the Irish end of a 500km cable that will connect Ireland to France’s electric grid.

(Speaking of costs, wind farm costs are continuing to soar because of supply chain bottlenecks. As I currently(pun half intended) understand it, this is the result of only a few companies having invested in making components for wind energy ergo the demand is higher than supply so the price goes up. But that, along with the environmental impacts will have to wait for another post).

Re the French cable, it’s worth remembering that Energia in their public consultation less than a month ago, replied to a question about whether the power generated at Waterford would be used overseas with a definite no. I suppose they could argue that there are no plans to send energy abroad but if a 500km cable just happens to be developed, well sure they’d be mad not to use it right? But there’s two (more)things worth noting here:

  • Public consultations mean very little. Don’t expect real answers.
  • That it is likely we are looking at a project of gargantuan proportions with each element kept seperate, publicly at least, until it is too late to lodge any reasonable objections.

It may be that the turbines, being prone to shut downs – when it gets too windy, when the energy company decides to cap output, when there’s maintenance to be done – may be the things that spin least in this story.

There are links to more details below and I will be trying to make sense of this on the blog over the next while. Thanks to Tripe and Drisheen for the heads up. Give them a follow, they are independent journalists in a world where the media are owned by Big Biz.

Meanwhile the Green Party are holding a session next Wednesday in Dungarvan

For those of you in despair or who just don’t want to know about such portentous events, I will be starting a diary of our coast with illustrations next year. We might as well record it and enjoy it while we have it.
