thread_title: Photo

message: The photo in section "Environmental effects" is misleading because it suggests the huge cloud is a cloud of pollution. Of course this is a cloud of condensed water vapor, which comes from the cooling towers. However, rather than remove just the photo, I suggest we remove or rewrite the whole section. As it is, it is biased and its contents are not verifiable. Ccfn (talk) 11:46, 3 December 2009 (UTC)
replies: text: The section is correctly referenced, to a sufficient level for the article to pass GA. With regard to the image, if you look closer, the trail of smoke can be seen to be coming from the main stack, not the cooling towers. The section and article as a whole are not biased. A rounded commentary of the station and its operations are provided, but a section on the environmental impact of the station must be included, otherwise the article would be seen as being biased in the other direction.

Just noticed the move here. 'Drax Power Station' is a proper noun, isn't it? And proper nouns are always capitalized, according to WP:CAPS. If 'power station' is not part of the name, then the article should be located at Drax (power station), per WP:PRECISE. Arsenikk (talk) 20:46, 3 March 2011 (UTC)
thread_title:  Requested move 

message: The article currently reads: "The station tested co-firing biomass in the summer of 2004, and in doing so was the first power station in the UK to be fuelled by wood.".  Is this definitely correct, I have a memory that Slough Trading Estate has burnt almost exclusively fibre-fuel for a lot of its lifetime?  —91.189.88.12 (talk) 14:20, 1 June 2011 (UTC)

message: http://www.guardian.co.uk/business/2012/feb/21/drax-scraps-plans-uk-biomass-plants 
Plan for plant at Ouse is dead. Seems should be merged as footnote, also links into plans to burn more biomass in original plant - so a good idea to cover both here. As for the proposed Immingham plant - don't know.. but see http://www.hvnplus.co.uk/news/immingham-biomass-viability-to-be-decided/8628530.article - it's been called " Heron Renewable Energy Plant" for a while
As an aside it may make sense to consider converting the article to a company article "Drax Group" with power plants as sections, if they start operating more than one plant.
Also the proposed Hull biomass plant is also dead  - there was a very similar sounding Dong Energy proposal that was cancelled 2010   bbc etc also note http://www.thisishullandeastriding.co.uk/Drax-halts-switch-biomass/story-11948807-detail/story.html which claims Drax dropped Hull plans in 2010, and was planning to build on same site as Dong Energy..? But other sources claim it halted in 2012 ???? Oranjblud (talk) 23:59, 1 April 2012 (UTC)
replies: text: Merge done - into history section - I can write more if sources are provided, but the merged article was completely unreferenced - so I had to work with what I could find..Oranjblud (talk) 19:32, 30 September 2012 (UTC)
thread_title: Merge proposal

message: *Post privatisation history goes to 2009 with a not very enlightening sentence on being downgraded from BBB+ to BB- (or something). After that nothing.
**Turbine refit - should be in the text body - is it finished yet?
**Biomass plans - as above -some are shelved
Also "dates" (year/month) eg The station's use of biomass has continued to increase and a target has been set for 12.5% of the station's energy to be sourced from biomass. This will contribute to the station's aim to cut its CO2 emissions by 15%. - doesn't say when  ... I know its in the reference - but the text should say. There's more than one like this.
One minor point - the image in Drax_power_station#Environmental_effects mentions CO2 - but the image is of a steam cloud - is this helpfully educational?? Maybe it should be changed.
I can do the fixing on the biomas plans but would prefer someone else to do the rest..Oranjblud (talk) 00:28, 2 April 2012 (UTC)

thread_title:  Blacklisted Links Found on the Main Page 

message: Suggest merging Drax Group - rationale
*The only purpose of Drax group currently or in the likely near future is Drax power station
*As a result Having both articles results in duplication of content.
Additional rationale:
*Drax Group is out of date, and unmaintained, with the exception of a link to 2013 financial reports
*Much of the content in Drax Group (eg the entire History section) is already in this article, in more depth, and referenced.
*This article also covers all aspects of subsidiary activities to Drax's power generation business in detail eg Fly ash, biomass supply etc.
*If Drax Group is not merged then it has multiple issues as stands.
In short 2 articles represent a Wikipedia:Content forking. I have no opinion on what the better article title is.Prof.Haddock (talk) 16:26, 14 July 2014 (UTC)

thread_title: Assessment comment

message: Article says: "The reinforced concrete chimney stands 259 metres (850 ft) high, with a diameter of 9.1 metres (30 ft), and weighs 44,000 tonnes. It consists of three flues..."  I believe this is an error.  The entire structure measures about 25m in diameter, where each of the three flues has a diameter of about 9.1 meter.  This is according to (inaccurate) measurements on Google Maps, and according to site visit, where the highth/diameter proportion looks rather 10/1 (or 259/25) than 30/1 (or 259/9.1).Bruno verwimp (talk) 23:37, 28 May 2016 (UTC)
replies: text: Good call on spotting that error! :) Using my copy of Advances in Power Station Construction (CEGB), the chimney is 259m tall with a 26m overall diameter. I've corrected and expanded the section accordingly from this source. Alas it makes no mention of the mass. Myfanwy (talk) 05:08, 4 December 2017 (UTC)

message: The peak output power is indeed an important metric. However it doesn't mean much without knowing how long it can last, in other words, the quantity of energy that is stored. Said quantity is formally expressed in Joule or more commonly in kW·h (here the order of magnitude is most likely MW·min).
Anyway, the promotional pamphlet cited as reference does not mention batteries other than an eventual plan illustrated by a link to nowher.  — Preceding unsigned comment added by Noliscient (talk • contribs) 16:14, 28 February 2022 (UTC)
thread_title:  200 MW battery storage, but lasting how long ? 

message: I am surprised that there is no mention of the operational history of Drax, which has had a number of dramatic failures.
In the late 1970s the rotors of two of the generators had to be removed and scrapped as they had developed very large cracks in the rotor body. (CEGB classified this as "Secret" at the time, although they later declassified it, which is why I know about it.) In the late 1980s and early 1990s some more generator rotors were similarly found cracked, removed and scrapped. Some years before that one generator had a catastrophic failure when an aluminium wedge in a rotor winding slot was ejected while the machine was on load at normal running speed. (I read an internal report about it at the time). I also heard that some time in the 1990s, while Drax was owned by National Power, another unit had a similar failure.  I have not heard anything since National Power sold Drax (no personal contacts there).
This is all interesting practical engineering experience.  Unfortunately it may be that there are no public domain documents describing any of these events, so no references, and hence not suitable for Wikipedia. DMWard (talk) 14:00, 15 October 2023 (UTC)
