Given the energy crisis and the government's seeming stance to not deal with any of the immediate issues facing the nation but paint a blue sky picture of the future what chance of revising this project that the Tories kicked into touch? The rhetoric now is sorting out clean energy linked to the climate challenge. Is it time to get this scheme back on the table?

It should never have left the table…it should be under construction as we speak. It’s all very well shutting down coal and gas fired power stations to save the planet but what replaces them? It’s going to be interesting when more electric vehicles starting plugging into an already archaic grid no matter what time of the day. | | | |

Specially when only the priviliged few can afford gas!
Petrol cars will be around a fair while yet mind, who can afford a new electric car? | |

Electric cars ? who will be able to afford the electricity to put in them. |  |

No, Never.
This country does not need 1 more megawatt of Intermittent Electricity production and certainly not at over £168 per MW.
It is only 320MW, barely enough to supply the all houses in Swansea district with power at peak output. | | | |

Yes.
A new clean energy supply, plus a nice place to walk around. |  |

The proposed tidal lagoon at Swansea Bay would have a capital cost more than 3 times as much, per unit of electricity, as the Hinkley Point C nuclear
power station.
The tidal lagoon proposed for Swansea Bay is estimated to have an annual electricity output of around 0.52 TeraWatt Hours (i.e. 0.52 billion units of energy). The developer’s estimated capital cost is £1.3bn.
The annual power output of Hinkley Point C will be 26.1 TeraWatt Hours. The developer’s estimated capital cost is £19.6bn, which was rounded up to £20bn to simplify calculations.
Using these figures, Swansea Bay’s cost - in terms of capital cost pounds per unit of electricity - is £1.3bn / 0.52 TeraWatt Hours. This gives a ratio of 2.5.
The equivalent figure for Hinkley Point C using the same calculation would be £20bn / 26TWh, which gives a ratio of 0.8.
The capital costs per unit of annual power output for Swansea Bay tidal lagoon are therefore more than three times that of Hinkley Point C (2.5 / 0.8 = 3.1)
It would cost only around £400m to use offshore wind instead to generate the same power as the proposed £1.3bn lagoon at Swansea Bay.
Over a 60-year period, the annual output of Swansea Bay outlined above would generate 30 TeraWatt Hours. This would come at a capital cost estimated by the developer of£1.3bn.
To produce the same electricity output each year using offshore wind would require only 120MW of built capacity, as offshore wind generates power around 50% of the time in comparison to Swansea Bay’s 19%.
Offshore wind plants, however, have a nominal lifetime of 25 years. In order to keep generating for 60 years they would need to be rebuilt around 1.4 times in addition to the original installation (for a total of 2.4 builds). A total of 288 MegaWatts of Offshore wind would therefore be needed over the 60 years — the original 120Mw of capacity built 2.4 times.BEIS’ capital and infrastructure cost estimate for offshore wind plants commissioning in 2024 — the same year that Swansea Bay tidal lagoon would begin generating — is£1,486/kW. 288MW of capacity would therefore cost around £400m. This assumes nofurther cost reductions for offshore wind beyond 2024.
So there you have , its too expensive for what it would produce | |

Have you included the cost of decommissioning a nuclear power station?
I still believe the tidal lagoon is value for money especially if todays scenario regarding gas prices is to be repeated in the future. | | | |

It was not the Conservatives that pulled the plug. The lagoon had full planning permission the only thing that was left was approval from National Environment Wales which for reasons unknown to itself failed to issue approval before the planning consent ran out. | |

Boundy couldn't have made it plainer.
What he didn't include was the running costs of both Wind and the Lagoon which would would require continual dredging to remove silt build up | | | |
| Swansea Bay Tidal Lagoon on 14:18 - Oct 8 with 2676 views | felixstowe_jack |
The Swansea lagoon was only designed as a pilot scheme to see if the the technology would work and the future proposals were for another 5 much larger lagoons around the British Channel and North Wales, which because of the difference in timings of the tides would provide power 24 hours a day not the 12 hours a day that Swansea would provide. | |

Sorry, in the real world it does not work.

Can’t see the decommissioning costs there plus the construction costs have increased to circa £23 billion and rising.
My way of thinking is two tides a day gives guaranteed power. The weather is variable so gaps in the network will always exist if we are totally reliant on solar or wind power to supply the majority of our energy requirements.
The other option of course is fracking which the green brigade are dead against. The next six months will be interesting indeed. | | | |

I am not in favour of large scale Nuclear, especially when built by EDF with their very poor troubled design.
I prefer SMRs and MSRs until something else comes along.
But at the moment cost wise Gas & Coal are king, in fact as far as coal is concerned we have missed out on a massive market by not having our own mining. | | | |

Yes there is, a combination of wind, solar and tidal with some Nuclear back up.
The problem with the costs, it seems to me, is the private comoanies building these things. Thye want guaranteed profit and quickly too so they get a subsidy from government.
Wouldn't it be much better if these things were built by the country, owned by the country and providing our essential power at cost? A nationalised power industry that could sell any excess to other countries with the profits reinvested into the network.
Just spitballing here. | |

Just about every other country in the world except the stupid west want it as well.
It is cheap, but getting more expensive due to China & India wanting massive amounts. | | | |

There you go pushing intermittent energy which Industrialised countries cannot run on.
Why don't you look at how variable and expensive they are? | | | |

Can't fault your logic, comparing a very bad Russian designed Reactor being run dangerously with modern far safer design.
As for Fukashima, when as the last time time the UK had a 7.6 magnitude earthquake and 40 ft Tsunami on the same day? | | | |

We’re caught between a rock and a hard place.
Russia are playing hardball over Nord 2, if they get that on line the Ukraine a major ally of the West could find itself in a position where Russia turns off the gas resulting in huge hardships for millions. It’s an issue that’s causing lots of Europe and Biden some angst and is well documented in the media.
We’ve hardly got any gas storage and are at the whims of the market as we aren't self sufficient for gas or electricity. We have to do something. | | | |

At one time, the Ukraine was getting huge concessions from Russia for gas, they were virtually getting it for nothing, but decided to get greedy , not pay their bills and siphoned off some of it for their use. | | | |

Biden gave Putin the do ahead for Nordstream 2.
I posted this on the Steel post, but is relevent here.
Just to put the current Boris the Buffoon Johnson's response to the Gas crisis in to perspective, he just prevented Shell from developing the North Sea "Jackdaw" gas field.
The guy is a very dangerous idiot and should not be running this country. | | | |
