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)[reply]

RegA? RegD?[edit]

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)[reply]
