100 F, 37C in Tokyo, TEPCO not having capacity problem

But it is of course costing an arm and a leg.

There were concerns about lack of power this summer, and it has been much hotter than the same time last year, but electricity use still at 91 to 93% of capacity for a few hours in the afternoons, and it will start to cool off from tomorrow.

Now having HUGE thunderstorm from around 5:00 pm directly over downtown Tokyo! Great! Temperature has dropped 15F, 7C, in just an hour.
TEPCO capacity utilization down to 85%. Assuming this storm doesnt do any damage, it is worth a fortune in reduced temperature.

The reactivated coal fired plants seem to be burning 11 million tons of coal per year, which is about 1% of what the US burns to generate electricity if these figure are right.

No doubt the Yokohama oil fired plant helped a great deal - it and its coal fired sisters:

Tokyo Electric, which operated the Fukushima complex, is adding an estimated 2.6 gigawatts a year of coal-fired generation capacity from two new plants that started operation this month.

It is also sourcing electricity from two coal-fired plants operated by Tohoku Electric Power Co that have been restarted after being repaired following the devastating March 2011 earthquake and tsunami.

The No.2 unit at Tokyo Electric's Hitachinaka plant, with 1000 megawatts of capacity, began operating this month, along with the 600MW No. 6 unit at its Hirono power station. The utility is also purchasing half of the output from the No. 1 and No. 2 units at Tohoku Electric's Haramachi plant in northern Japan, each of which can generate 1000MW.

In total, these coal-fired power plants are expected to consume about 11.5 million tonnes of coal in a full year of operation.

Yep, we be burnin a lot of fossil fuels...

Although if it is only 11 million tons per year, that is nothing compared to the 1 billion tons per year of coal the US burns for electricity... just 1 percent of that.


"In 2009, there were 1436 coal-powered units at the electrical utilities across the US, with the total nominal capacity of 338.732 GW^[3] (compared to 1024 units at nominal 278 GW in 2000).^[4] The actual average generated power from coal in 2006 was 227.1 GW (1.991 trillion kilowatt-hours per year),^[5] the highest in the world and still slightly ahead of China (1.95 trillion kilowatt-hours per year) at that time.^[6] In 2000, the US average production of electricity from coal was 224.3 GW (1.966 trillion kilowatt-hours for the year).^[5] In 2006, US electrical generation consumed 1,026,636,000 short tons (931,349,000 metric tons) or 92.3% of the coal mined in the US..^{[7]"
