Power-line objectors threaten legal fight

Published Date: 20 April 2009
PROTESTERS fighting plans for a new power line that would cut through some of the most beautiful parts of Scotland have threatened to take the government to court if the proposals are approved.
Dennis Canavan, president of Ramblers Scotland, believes they could have a case for a legal challenge against the Beauly to Denny transmission line on the basis that the public inquiry process was flawed.

A decision on the controversial power line
, which has been planned since 2005, is expected later this year. A legal challenge could further delay work starting on the new line.

The proposal has divided opinion, with energy groups arguing the line is crucial to enable further development of renewable energy in Scotland.

However, campaigners and local communities that would be affected by the lines believe it could damage some of the most beautiful areas of Scotland.

Mr Canavan, a former independent MSP, told The Scotsman: "I think the inquiry was flawed because the reporters would not allow evidence on alternative routes to the Beauly-Denny proposal, and there are viable alternatives that should be given very serious consideration.

"That could be subject to legal challenge. I don't understand why the inquiry reporters did not allow that evidence to be taken on board and fully examined."

He believes alternatives that should have been considered include upgrading the existing east coast transmission line, which would be closer to the proposed sites of new wind farms. Another option would be to use a network of sub-sea cables down the east coast.

He added: "Technically I think (a legal challenge] is possible on the grounds that the inquiry was flawed and there was no opportunity for the presentation of alternatives to the proposed route."

There have been more than 18,000 objections to the proposals, which would see about 600 pylons erected, each about 200 feet high.

The 400,000-volt power line would replace the existing 132,000 volt line that stretches from Beauly, west of Inverness, to Denny, west of Falkirk.

A £10 million public inquiry has heard about the merits and downsides of the 137-mile line, which would cost £350 million.

It is opposed by the National Trust for Scotland, the John Muir Trust, the Mountaineering Council of Scotland and the Cairngorms National Park Authority, among others.

However, energy groups have argued that the new transmission line is essential in order to meet renewable energy targets.

Half of Scotland's electricity must be provided from renewable sources by 2020, but more than 115 Scottish renewable schemes are currently waiting in a queue to plug into the grid before they can transmit their electricity.

A report on the plans was handed to ministers in February, and a decision is expected in the summer.

It is quite amazing that these protestors do not want High Voltage Transmission Lines because of the blight to scenic countryside when there is not the same outcry about wind farms which are far more of an eyesore than transmission towers spaced at fairly reasonable distances apart.

Wind farms are a waste of money, and taxpayers money at that, when they still need to be backed up by conventional generation sources. Maybe all these protestors should switch off their electricity for 24 hours and see how they like it.

Even Denis Canavan is getting it wrong, alternative routes should not even come in to the equation as strengthening the grid is simply not required.
The issue is not about renewable energy, it is about highly subsidised wind power stations. The wind industry is screaming because they see a limit to their scam.
Wake up Scotland, we are being shafted. The Scottish governement are desperate to approve this line in order to satisfy their puppet masters in the wind industry.

" . . alternative routes should not even come in to the equation as strengthening the grid is simply not required."

This seems to contradict the penultimate paragraph of the article:-
" . . more than 115 Scottish renewable schemes are currently waiting in a queue to plug into the grid before they can transmit their electricity."

Here we go with another load of people complaining and objecting just because they can.

If you want electricity, you've got to have power lines, in the same was as if you want mobile phones you've got to have transmitter masts...

The reason for the upgrade to 400,000v is so that the grid can take the additional power generated by the wind farms. It's simple, basic schoolboy physics.

Then we have people like nabodican who think there is some kind of conspiracy because in order for wind farms to contribute to the grid, they first have to be connected to it.

Do people really have nothing better to do than to moan? If they carry on like this, we'll never get anything done.

Think most people object to the power lines being above ground and would like to see them buried below ground and out of sight.

3 &4 You are missing the point, Scotland does not need the electricity produced by these windfarms and it is technically impossible for them to replace any of our coal or nuclear power stations.
The queue for grid connections is only there because of the easy money availlable from the subsidies.

#5 - Please explain what you mean instead of showing complete ignorance of the subject and a lack of sympathy for the Scottish landscape - idiot!

"...would like to see them buried below ground and out of sight."

Oh yes. I'm aware of that. The problem is that to bury 400kV lines underground would require them to be buried at a considerable depth to avoid the possibility of someone inadvertantly digging down into them. Additionally, the cables would have to be heavily armoured and waterproofed... And they would need to be substantially larger than pylon borne lines because there would be no air cooling. It may even be necessary to install cooling pumping stations every so often as well.

And if something did go wrong with the cable, it might not be immediately apparent and could make the surrounding ground live---400kV is an awful lot of volts and at times it will behave quite differently to the way lower voltages behave.

In short, burying the cable would be orders of magnitiude more expensive than hanging one on pylons and would be a lot more labour intensive to maintain in the long run.

I am no fan of wind-farms either, but it appears that there is a groundswell of opinion that supports them, we do have them, therefore it would be a pity not to use them properly.

These new lines will also carry power from the new batch of nuclear stations that will be coming on line at some point in the not-too-distant future.

I generally support all forms of renewable energy but Canavan raises some important points.

However renewable energy requires modernized transmission infrastructure and ALL UK mainstream political parties have varying commitments to generation and all this needs new or upgraded transmission regardless.

The Denny route exists already, though it has smaller pylons, plus the New route will have 2 rows, so it will certainly be much more visible. However it has to go somewhere. It cannot go underground unless at approx 5 times the cost + a full road, under sea still has to go overland for large stretches etc. Overall it is much easier to object than to propose viable alternatives on these issues.

The main alternative they wanted to have considered was down the east coast iirc, but those on the East coast would then object, stating that a cheaper more direct route to the central belt is available, on an existing route etc.

However, Canavan is correct, the Inquiry should have looked at all the other evidence put forward which could have avoided or reduced this mess.

Do not be fooled by the article that it is public groups such as ramblers who are against the project. Some of the main actors against are estates or other ‘interests’:

One is Eilean Aigas Estate see www.privateislandsonline.com/aigaseuuk.htm For SALE
Conflict of interst?
Another is Heritage Solutions, etc….
All of Scotland above the central belt cannot remain an undeveloped wilderness for Landed families, private interests and trusts or that’s all there will ever be.

Windfarms should be built on remote Scottish islands or in the sea and the cables taking the power south should be undersea cable - invisible and no cooling issues.

Job done.

The points you make in the first paragraph of you response are quite valid. Most arise because present High Voltage (HV)transmission is Alternating Current (AC).

However, I recently read somewhere (probably the New Scientist) that there is increasing interest in Direct Current (DC) for HV transmission. This has the big advantage that there is not the same heating effect so that a cooling system is not required. I have no idea about the relative costs of overhead and underground HV DC transmission.

As regards your following paragraph - "And if something did go wrong with the cable, it might not be immediately apparent . . " my understanding is that if an existing HV overhead cable breaks then it is 'dead' before it hits the ground i.e. the fault detection system is VERY fast.

Hugo of Garven,

Your points and those of several posters are certainly valid but underground or undersea routing is really a no brainer IF it is clearly best overall. The inquiry did look at "A generic comparison of high voltage direct current (HVDC) transmission with HVAC transmission with reference to the proposed Beauly-Denny interconnection."

However the transmission argument is done by those who want to route it overland and would not be involed or paid for undersea or underground. Some private interests are against etc. Canavan is trying to show that options to transmit using pylons could have used a different route or at least that all contributions should have been considered and weighed equally. Thats the Key - is it a fair and full inquiry? You certainly wont get any answers in the hootsman.

The problem is with newpapers (sic) like the scotsman is with poorly researched articles because they cannot even be bothered with a 10 minute google or just wish an angle to spin with one side of a debate. Many amateur blogs are better researched and reported.

I would say windfarms should be built as close to the power requirement as possible. Let skyscrapers in London (say) have windfarms on their roofs, for example. This should please both the carbon dodgers and the don't-ruin-my-landscape-ers (of which I am one, worried as I am mainly about archaeology).

"This has the big advantage that there is not the same heating effect so that a cooling system is not required."

I don't know where they get that idea from. The heating effect comes from the effect of resistance of the power lines---nothing to do with AC verses DC. With AC the transmission is subject to impedance, which is the complex number expression of DC resistance and AC resistance due to inductive reactance and/or capacitive reactance. On a typical power line, the effects of induction and capacitance are negligable---especially at the low frequency of 50Hz.

Essentially then, the DC resistance of the line has the same effect and produces the same heating effect whether AC or DC is used, so you would still require cooling with both.

"my understanding is that if an existing HV overhead cable breaks then it is 'dead' before it hits the ground i.e. the fault detection system is VERY fast."

Maybe so. A lot of factors depend on this though. My point was that overhead cables are visible and even a layman would be able to tell if there was an obvious fault with them. Underground cables are hidden from view.

It is possible with an underground cable to get a partial breakdown in insulation that could potentially cause problems without necessarily tripping any safety measures. Generally, two things happen with overhead lines---breakage and shorting---both of which are instantly detectable automatically.

There's a case for upgrading the highland line but SSE have done their dmnest to annoy public opinion. Did they even appear (the directors) at the last public enquiry?

Grids are most useful but could be outed by solar discharge. Are there any precautions against this event? The lines can be replaced but the big transformers will be trashed too.

Who cares? The modern multinational utility is not run by engineers but for bean counters, directors and lawyers. Whereas electricity travels at ~ the speed of light.
