message: What does a KW or MW generator sizing or capacity mean? Is it that many Kilo Watts or Mega Watts per second? per hour? per day? This article should explain sizing / capacity at the top.
By comparison, most electrical meters are KWH or Kilo Watt Hours.    —Preceding unsigned comment added by 208.58.202.32 (talk) 07:51, 19 April 2011 (UTC)

message: Moved (Tone) tag to this section as top portion of article not bad but from this section down appears a straight copy, and some material and later sections require re write to suit context as possible CopyVio, and over weight to article. Section has relevance as informative to readers of an overlooked effect of non use of equipment.

replies: text: That was what we in the industry call a mistake -which I thought I'd fixed.  Looking closely at the photo the Egyptian gen-set is just sitting on the sand, and there's no muffler hooked up. I greatly doubt a tourist place is going to tolerate the roar of even a medium-sized genset at full output, so I conclude this genset was in progress between unloading and installation. --Wtshymanski (talk) 00:36, 20 August 2008 (UTC)
thread_title: To do

message: I disuppute that - the main reference has been published at an open university conference, and by the Institution of Diesel and Gas Turbine Engineers Journal, the IDGTE, and in a book, Renewable Energy and the Grid , Ed Godfrey Boyle, publisedh by Earthscan, p 143 - 147.
How can you get more authoritative on generators than the manufactureres manuals and data sheets?Engineman (talk) 15:12, 3 October 2008 (UTC)
replies: text: The tag says "third-party". A manufacturer is hardly an independent source. Secondly, very little of the article is referenced using inline citations - this makes it very difficult to ascertain whether a particular statement comes from a source or whether it is the opinion of the editor who added it. Thirdly, there are huge chunks of prescriptive text in this article which offer advice or try to teach subject matter. This is not the purpose of an encyclopedia: we are here to describe content, not to act as a manual or textbook. Chris Cunningham (not at work) - talk 15:22, 3 October 2008 (UTC)
thread_title: unreliable sources

message: While the recent additions to the article constitute valuable addition of information, they have rather disrupted the article flow. I hope to take some time to rewrite them in order to be better integrated with the article as it was. In the course of doing so I'll remove the prescriptive information and try to tag the article for appropriate inline citation. Chris Cunningham (not at work) - talk 15:36, 3 October 2008 (UTC)
thread_title:  Recent additions 

message: I understand where you are coming from on this, but no body else is really interested in the minutea of generator installation....the manufacturers are not going to lie about it, it is not in their interest.
There is no better source of information.
Any way if you wait, I'll try and get round to finding some better references.  I think anyone turning to this article is entitled to be told in simple terms how to ensure that a generator actually works, and how to ensure it is installed properly.  to do anything less strikes me as being overly pedantic.Engineman (talk) 15:51, 3 October 2008 (UTC)
thread_title: manufacturers

message: Well this article doesn't act as a manual or a text book - it advises people of the issues gives them a bit of insight and directs them to the real sources of know how - the manufacturers detailed installation manuals and data sheets.Engineman (talk) 18:13, 3 October 2008 (UTC)
replies: text: "A bit of insight" is precisely what is meant by acting as a manual or textbook. The tone of the article isn't fitting an encyclopedia: from the guestimated fuel costs to the overly-detailed guide to the causes of engine glazing, this article spends far more time discussing the intricacies of running and maintaining a diesel generator than it does actually describing it as other engineering articles do. As I say, I'll try to work on this soon. Chris Cunningham (not at work) - talk 18:23, 3 October 2008 (UTC)

message: Please consider improving the clarity of the third sentence under Rating. It says:
"That is a standby set is only expected to give its peak output for a few hours per year, whereas a continuously running set, would be expected to give a somewhat lower output, but literally continuously, and both to have reasonable maintenance and reliability."

message: Hi, from translation point of view I changed the french interwiki directed to this article to engine generator article. This article is a spcific case of engine generator.

thread_title:  generators 

message: Background :Electricity supply companies charge consumers for the 'amount of power' that they consume in addition to 'their rate of consumption'. For example: Two consumers who both use the same amount of electricity in a month but one uses it over two days and one over the whole month, then the one who uses it over the two days will be penalized in their billing because the supply company will need to install more expensive, higher capacity equipment to supply them. 
The financial benefit of peak lopping is reflected in the billing by the supply company. There is a charge per unit energy in cents/kWh and a demand charge which is based on the maximum demand that is recorded for the billing period, this is in $/kVA (power) the much more expensive one is the demand charge so it is better to draw energy for longer periods of time at cents/kWh than to draw it quickly and pay a premium rate for the demand in $/kVA. 
Peak-lopping refers to a situation whereby the consumer chooses to cut the peak demand that they require in order to avoid paying the penalties associated. 
There are various means of implementing peak-lopping measures. I some buildings the Building Management System will simply switch off items such as Geysers and certain Air Conditioning units when the building starts drawing too much power. 
Other means of peak-lopping generally involve storing the energy in some way during times of low demand for use later when it is needed during times of higher demand. An example of such a solution would be to use electricity during the night to make ice in an insulated ice storage tank and use the ice during the day to cool the Air conditioning units. This would reduce the amount of power they require during the day when there is a high demand for electricity.  — Preceding unsigned comment added by 182.64.255.228 (talk) 07:01, 2 June 2014 (UTC)

thread_title:  Engine damage (2) 

message: I'm trying to educate myself on 100kw or larger diesel power plants.  Particular questions?  Continuous run VS. off time switching to battery systems.  Typically generators kick on when battery reserves reach 25%.  Are there increased safety issues with these shutting on and off?  Does it cause maintenance issues in the long run?  That's my original hypothesis.  What is the risk of hydrocarbon gas build-up while the generator is shut off?  I know others have written that it is best that the generator runs non-stop.  I believe Caterpillar even recommends that for its larger generators.  You pick a load level, you stick with it and run it continuously.  Some of the big CATS can run non-stop for 14 years.  I also wanted to confirm what I believe could be harm to a larger generator run at only 1/4 load.  What are the variable for maintenance or performance issues compared with 1/4 load, 1/2, 3/4 and full load?  I know to get the best bang for your buck on fuel consumption it is best some times to run at 3/4 load with these large generators.  My conclusion right now without more information is that it will be harsh on a 100kw generator to shut on and off for one year.  But some underground emergency facilities plan on relying on just such a system.  Alarmingly these facilities are placing their back-up generators close beside their primary generators.  Facilities like this typically might have two CAT 400's. I'm questioning the wisdom of putting those big CATS side by side if they have internal fuel tanks.  I also question the wisdom of placing these systems underground.  Every time that big generator kicks on it will kick out an electrical field.  Having it kick on and off every day is 365 start-ups.  I don't like the idea of that at all.  That would certainly present problems I would think.  Common sense is telling me that, anyways, whether it is a CAT, A Cummins, a Generac or any of the big ones. Comments from an actual engineer please?
