somewhat dated

as the project is completed shouldn't this article be changed to present/past tense and start having some metrics on operations....

Yes, definitely. You can help with that! The first thing is to find more recent sources of information: for example, there should be news stories about the completion of the project and beginning of operation. If you can find some good sources, you are welcome to add them to the article and update the text. If you prefer, you could link the sources here for others to use in editing the article. Thanks. --Amble (talk) 21:23, 11 January 2015 (UTC)[reply]

Power rating

Gross or net ? Here the documentation for ps_electrical_capacity in Infobox documentation. Current gross installed capacity in megawatts, or planned capacity from those under development. If 110 MW is the Power Station net output, gross capacity should be something more. If value is not stated, the best guess is the power turbine capacity, as by provided source. --Robertiki (talk) 02:40, 30 June 2015 (UTC)[reply]

Both the developer and the owner give the rating of the power station as 110MW.[4][5] I think what's important is what is delivered to the grid, the customer, gross is irrelevant. Wikipedia definition is a bit idiotic and contradictory. The Infobox definition implys gross but the associated popup referrers to Nameplate capacity i.e "Nameplate capacity is the number registered with authorities for classifying the power output of a power station usually expressed in megawatts (MW)" which would be nett. --Andynct (talk) 11:52, 3 July 2015 (UTC)[reply]
EPC Contractor ACS Cobra, as sourced, states 125 MW. Sorry, but gross power is what was agreed. Otherwise, what happens, if some write the net power, other instead follow the instructions ? A mess.--Robertiki (talk) 04:51, 17 January 2016 (UTC)[reply]
With your definition you are claiming that every nuclear power plant on Wikipedia is listed incorrectly as they are listed by net power output and not gross power output and always have? So every power station listing on wikipedia needs to change? Have you actually thought about it? I don't think so. Are you insisting nuclear power stations pages inflate there output figures by about 50MW per reactor?Andynct (talk) 14:05, 27 January 2016 (UTC)[reply]
As per Template:Infobox_power_station for ps_electrical_capacity, instructions are: "Current gross installed capacity in megawatts, ...". You could propose to change that. --Robertiki (talk) 15:48, 27 January 2016 (UTC)[reply]

Standard utility terms define gross generation as what is measured across the generator terminals and net generation as what is sold to the grid. The difference is known as plant aux power and is what is used for plant purposes such as the molten salt circulating pumps, boiler feed pumps, fans for the air condenser and power to position the plant heliostats in reference to the position of the sun. There are probably others but these are the big users. For a plant of this size 15 MW ( 125 gross - 110 net) seems about right. — Preceding unsigned comment added by Sgs351a (talk • contribs) 20:41, 23 December 2016 (UTC)[reply]

Crescent Dunes commissioning

The commissioning of a thermal plant is not like flipping a switch of a photovoltaic plant or a wind turbine. It takes time, more if it's a prototype. It follows at least three stages:

  • the first grid connection
  • the commercial production stage
  • the production ramp-up

An example is the new Edwardsport Power Station. Completed in 2012 (2015), started operation in 2013 (2016), and ramped up production until 2015 (2018). And Crescent Dunes suffered an 8 month freeze due to a leak in a molten salt tank (and that would give 2019 to be a fair timing). Why Ivanpah and Crescent Dunes are so studded with unfair critical sarcasm, and no one does the same with the coal plants that take a similar timing ? Beside, how can a calculated capacity factor be accepted without at least one straight year of production ? Is it the way to compare or evaluate a technology based only on a partial year ? That would/should be enough, but I will take a look at the cited source. The reputation of the cited source is questionable, the first author, for example has some critics at least. And it may look understandable if you look for who Alberto Boretti has worked. Stefania Castelletto works for the automotive industry at a Australian University. Sarim Al-Zubaidy is more a politician. I won't comment further about that. --Robertiki (talk) 04:16, 15 June 2018 (UTC)[reply]
