I am copying all this out in case I need it another time. Like poor Clive, I am learning these things about other states first. . . however, I Do apply them to the U.S. as well. And thanks again to Vadim for getting us started. Bonnie Dear Tajik Boy,
Oh, thank you! I am copying all this out in case I need it another time. Like poor Clive, I am learning these things about other states first. . . however, I Do apply them to the U.S. as well.
And thanks again to Vadim for getting us started.

Kilowatt hour is the actual electricity production. If a plant has a capacity of say 100 KW. It may produce 100KW per hour. The generated power (KWh) then is represented by (a) Plant’s capacity x (b) Number of hours it has been operational A more conventional way of calculating KWh is: Kilowatt hours =capacity x 8760 (24 hours x 365) x capacity utilization (1-100%) So, if Tajikistan produced 16.5 billion KWh then: 16.5 billion/8760/80% (assumed capacity utilization)=2.4 million KW This means that Tajikistan used 78% of its dam’s capacity. In other words, 78%=2.4/3*98% (where 2.4 is current capacity, 3 is Nurek’s project capacity and 98% is Assumed Nurek’s share of total generated electricity in Tajikistan)

But it occurs to me that probably Clive had never tried to take a picture of a U.S. power plant--because, plants that appear to be doing what they're supposed to are not as interesting as plants that aren't. Also Clive's subject is much less that of power plants than of Tajikistan. Also, you can bet that if Clive was sufficiently interested in US power plants to take a picture of one, then he would most likely be outraged to have anyone try to stop him here too. So there are really two double standards here and one is the cultural-centric one already mentioned, but the other is between security/secrecy vs. journalism/info-gathering. So, stupid as it all may sound, not all of it is personal. . . I'm guessing, anyway. Bonnie Also, about that double standard that Andrew and Tajik Boy mention: oh, of course.

However, I couldn't find the relationship between kilowatt and kilowatt hour, and I suspect it has to do with efficiency ratios. Also, no matter what the plant can take, if the rest of the system cannot accommodate that output, then you are stuck with a lower number. I don't know this from electrical engineering, but from previously living in New Orleans (flood zones). Maybe someone can find the efficiency rate of the power plant or is an electrical engineer and can fill us all in. Great article! And I tried. . . Dear Vadim,

One of these two possible explanations: 1. Double Standards (i.e. do what I say, not what I do) 2. Western folks should be exempt from whatever rules there are in the country because they are "trying to help". “Why does Clive seem surprised that they were suspicious of a foreigner taking snap shots of their number one source of electricity?”
