Power supply

Does anybody have information about where the electricity for new electrification schemes will come from? The electricity generating companies are closing old power stations faster than they are building new ones so there is likely to be a shortage, even without new railway electrification.

In recent years the trend has been to move away from connections at 132kV and to connect to the SuperGrid at 400kV. The first use of this was back in 2000 when a supply was taken from Wymondley 400kV grid to supply a new feeder station named Corey's Mill (located about half way between Stevenage and Hitchin). For the WCML supplies were taken from the 400kV system at Elstree (Bushey), Leighton Buzzard, Patford Bridge (Long Buckby Wharf) (just south of Rugby), Brereton (Rugeley) , Oxenholme and Harker. On the GWML there will be a new supply at Didcot. In terms of providing the extra power I cannot say, but if there are rolling power outages in your area ... then I suggest you phone Network Rail to complain!!

Thanks. I'm trying to persuade Network Rail to build its own power stations but I don't suppose the government will allow it. Biscuittin (talk) 22:02, 15 July 2015 (UTC)

Very unlikely. You have to remember that a lot of the power is needed for the third rail system south of London, and I cannot see anyone agreeing to building a power station in London. Another important issue is reliability. As I am sure you are aware, London Underground used to have a power station at Lot's Road in Chelsea. It was closed not only because LUL needed more power that it could provide (let alone the fact that it needed major expenditure to renew the old equipment), but also because LUL needed better reliability, and wanted to reduce it's dependence on Lot's Road. So adding the supply from the National Grid at Mansell Street improved their ability to operate in the event of problems with Lot's Road. Also, the need for more power due to new trains increases the current flowing in the cables of their 22kV distribution system. So providing power locally at multiple locations around the system helps to avoid overloading existing cables better than having power from a single power station.

Thank you. You are a mine of information. Biscuittin (talk) 21:03, 16 July 2015 (UTC)

Network Rail are also trialing using SFC- Static Frequency Converters which will also help. There are two being installed very close to the Scottish borders near Berwick on Tweed. Marshall Meadows to be precise. GRALISTAIR (talk) 19:42, 5 January 2021 (UTC)

Updates

I can see this article needs a fairly major update with quite a few schemes actually completed and thus no longer "proposed". I will attempt some when I get the time. GRALISTAIR (talk) 16:01, 20 September 2019 (UTC)

I have updated several sections to show to the current status of each project. The layout of the article was confusing in that there were 2 sections "Proposed Routes" and "Delays and Cancellations". Some details of the Delays and Cancellations were included in the Proposed Routes section and some information was duplicated in both sections. I have tidied up the article so that the article now has an introductory section followed by a section for each area.Chris1515 (talk) 22:11, 18 May 2020 (UTC)

I agree with GRALISTAIR that this article needs updating since some "proposed" schemes are now complete. I propose when a section of line is electrified it should to added to the list of existing systems in Rail Electrification in Great Britain. Any historical information about the line's electrification project should be copied to the article for the particular line, if not already there. The section would then be deleted from this article. I also believe that this article should only deal with the electrification of existing lines. New lines that will open with electric power should not be included since they are covered in other Wikipedia articles. This means that the section on Crossrail would be deleted, as it is a new line. I will wait for any comments before making these changes.Chris1515 (talk) 22:44, 18 May 2020 (UTC)

I have made a start updating this article by creating a section called competed projects GRALISTAIR (talk) 20:40, 19 November 2020 (UTC)

IRP

I have made a start but this article needs updating with some brief IRP info as it affects proposed electrification GRALISTAIR (talk) 01:35, 12 January 2022 (UTC)

Article title

List of proposed railway electrification routes in Great Britain - I feel a better title would be "List of railway routes proposed for electrification in Great Britain" GRALISTAIR (talk) 17:16, 23 November 2020 (UTC)

MAP

Although having the 2012 HLOS Map of proposed electrification is good to bring up to date it needs the TDNS map including. My wikipedia skills are not good enough to do this so if someone would be so kind I think it would be good GRALISTAIR (talk) 21:17, 19 January 2021 (UTC)

I think I have succeeded but it may need a bit of a clean up from another editor. GRALISTAIR (talk) 21:30, 19 January 2021 (UTC)

On Great Britain

This should really be On Great Britain not In. The only legal definition of Great Britain is as an Island and you are on Islands not in them. It is a bit more complex though as at least two minor islands are connected, Anglesea and the Isle of Sheppey.--Kitchen Knife (talk) 13:23, 23 December 2021 (UTC)
