Talk:Ancillary services (electric power)

In 2015
I added sections about additional types of ancillary services and added information about the potential role that renewables and electric vehicles may play in providing ancillary services. I also elaborated on the definition and summary. The section on reactive power is not very accurate and could definitely be improved. There are many different types of ancillary services, and the way the article is currently written makes it sound like the six mentioned by FERC are the only types, which isn't strictly true. Additionally, a section on the economics of ancillary services would be interesting to add, however I do not know enough about the economics to do so. Cb8383 (talk) 16:52, 27 April 2015 (UTC)

RegA? RegD?
Just ran across references to RegA and RegD which are characterized as related to following demand vs responding to dynamic instability. Are these dividing the six services into two, or are there RegA, RegB,... RegF? These two, RegA RegD, seem to show up in PJM articles in google. Mulp (talk) 19:05, 15 September 2016 (UTC)

Redirects from "Ancillary service" and "Ancillary services"
The current title seems to be WP:MISPLACED given that there exist redirects from and.

Although there exists an unrelated use of this term in medicine, referring to radiology and other diagnostic tests, that does not matter under current policies.

Just pointing this out, as I'm not yet sure what should be done. --SoledadKabocha (talk) 20:45, 27 May 2024 (UTC)


 * If you can point to other articles that describe things called "ancillary services", we can create a WP:disambiguation page in place of one of them. This will require also redoing ("disambiguating") all the links to the newly created "disambiguation page". If the other (non-electrical) meaning is not yet described in Wikipedia, you might want to describe it first. Викидим (talk) 21:18, 27 May 2024 (UTC)


 * From a quick glance at Special:PrefixIndex/Ancillary, the medical meaning does not yet appear to have an article that uses that specific word; the closest article would be Medical test, but it doesn't mention the word "ancillary," making it unsuitable.
 * I was already aware of all this, and I did figure out myself that one of the offending redirect titles would need to become a disambiguation page if a suitable article existed (presumably because WP:SINGULAR), but I'm in no hurry to get this resolved - you could say I was just brain-dumping. --SoledadKabocha (talk) 00:53, 28 May 2024 (UTC)
 * Per MOS:DABRED the red links on disambiguation pages are discouraged, so some kind of text (not necessarily a dedicated article) will be needed before the suggested improvements in the Ancillary service. Викидим (talk) 01:03, 28 May 2024 (UTC)
 * Thanks, but I am already aware of that guideline&mdash;I am in no hurry to create the disambiguation page either; I just wanted to make sure what was on my mind was noted, and none of this was intended as a request for help. --SoledadKabocha (talk) 04:16, 28 May 2024 (UTC) (copyedits: 04:23, 28 May 2024 (UTC))
 * I am sorry for misinterpreting your words "I'm not yet sure what should be done". Викидим (talk) 05:30, 28 May 2024 (UTC)
