The Future of Power Generation in Great Britain

[turbobloke]

Maybe "indexed and adjusted for inflation" has a new meaning, or not.

The non-coincidences involve NEM and intermittent energy generation.

There remains the unsolved problem of intermittency and now "Renewables Industry Faces $Billions In Compensation For Early Repairs" as unrelaibles live up to their name. Any lame excuses from the industry?

"However, there has been disagreement between Ørsted and Siemens Gamesa as to whether the problems are covered by the guarantee or are a case of ordinary wear and tear."

Something about that sounds very familiar, do Siemens make cars too?

I have involvement in the subject on various angles
The article is not wholly accurate.

In what way?

[StephenGalley]

I think we should build a small number of new generation coal fired power stations, like what Germany is doing, and sink a few new coal mines in Britain to fuel them with. We have got all of this coal we may as well make use of it, it is like an oil rich country not making use of its oil. It would provide a lot of well paid jobs.

Renewables cannot be relied upon for all of our needs as wind and sun are not reliable, and nuclear is inherently dangerous, you have toxic waste that lasts almost until the end of time, also accidents happen (Fukishima, Chernobyl, etc.), also if a terrorist blew up a nuclear power station it would be a disaster whereas if they blew up a coal power station it wouldn't be anywhere near as bad.

Hence why I said its not so straight forward

Smoke and mirrors involving unreliables? Perish the thought.

We also do price assumptions based on a year here in the dirty (still mainly hydrocarbons but some renewables now) energy sector.

It’s a phenomenon called leading edge erosion- and i have mentioned it on here several times before

I don't see anything in what you say that backs up your claim that the article lacks accuracy.
Pleased you agree that there are design failings leading to early failure.

Paddy_N_Murphy said:

…how can you say that the article lacks accuracy ?

I didn't. You did and you've failed to justify why you consider it not to be accurate.

[rolando]

Paddy_N_Murphy said:

LOL, I dont need to justify fk all to you frankly.

I know what I know and you have been hell bent to dispute every comment I have made on this thread.
There are inaccuracies.

Not for the first time you've avoided answering my questions. It is a normal reaction from folk in your "industry" when faced with facts. I'm used to it and can spot bullstters from a mile off.

And you do need to justify what you say because your industry relies on subsidies paid for by end users of the electricity you generate when the weather happens to favour windmills.

Children please !



How long was an offshore blade meant to last ? I imagine it's a very harsh environment and blade wear would be expected from impingement, probably from water droplets, or is it ice/hail flowing over them ? Can't imagine it's cavitation

Difficult to blow up a well designed nuclear power station. All methods of generating large quantities of electricity create risk, civilian nuclear power in the UK is statistically the safest method of generating large quantities of electricity. The radioactivity from nuclear waste falls over time, nuclear waste should be regarded as nuclear fuel.

It's not a dodo yet.

Over 3 million tonnes of coal was 'surface'-mined in the UK in 2016.

Try the content from these headlines, easily found:

"The engineer who plans to bring coal mines back to Cumbria" (article dated Feb 2017)

"Banks Group aims to open UK surface coal mine in 2018" (article dated Jul 2016)

"Inside the automated mega-mine of the future"
That was the future back in 2008!

Britain won't doo mining again - various reasons including - Who actually would work the mines. At what cost ?

If coal is used, it's not from here.

Let the market prevail: £17k per annum at the local call centre or £100k+, non-PC banter and cheap session beer at the social club.

The UK sits on trillion of tons of coal.

Do you glue copies onto the blades to fix the erosion?

Given the tip speed and forces involved the blades are an impressive bit of engineering.

i always wondered why they didn't use the 3m product the helicopters in the gulf used to protect against erosion by the sand. maybe too expensive ?

[alangla]

Seems to be an awful lot of coal being burnt in the last week, what with the cold weather and high gas prices. Does this mean that if this situation recurs in future years when there's no coal energy, we can look forward to sky-high wholesale electricity prices?

[Ali G]

Why bother?

The entire structures are all out of date in 18 months anyway and need replacing in totality.

It's more cost effective that way.

Because it fails / doesn’t last.
18months and shredded I believe
And then an arse to scrap off and reapply

I was thinking that too, suprised it doesn't work well.

Ah well, we use stelite tips to protect our turbine blades.

Do the nuclear plant turbines / gernerators move around from generation station - OEM refurb - next berth at a new nuc / non-nucstation. I'm sure one of the Oil powered stations we were decommissioning a few years ago was sending part of the turbine train to be refurbed having lived part of its life in at least one of the Huntershamlepool Point AGRs - but wasn't sure if that was just the owner trying to make us extra cautius in decommissioning?

At least I think that was the plan until it was left under a leaky dripping roof turbine hall for two years with a canvas covering the rotors / stators (I forget which one - the movey spinny bit, not the stationary bit) pooling water.....

...nice to see Fiddlers Ferry ramping up last night to "full-tt" on all boilers as I flew over the Mersey! Roll on coal.
