The Price Point in Japan

fourth-reactor-building-ohi-nuclear-power-plant-433250Outside Japan, it seemed inevitable:

Japan has given final approval for the restart of two nuclear reactors, a move that will end a total shutdown of the atomic power sector caused by safety fears raised by last year’s crisis at the Fukushima Daiichi plant.

Inevitable because the Prime Minister Yoshihiko Noda worked hard to get the approval of the prefecture (state) officials because all signs were that Japan would suffer brownouts and blackouts without the Oi (I’ve also seen it as Ohi) reactors in Fukui Prefecture. In any event, though the announcement is notable, it will still take awhile to get the reactors back online.

Kansai Electric said that further tests and checks were required for the two Oi reactors, but it expected to be able to start generating electricity with the No 3 unit in early July, with No 4 following later in the month. It would take each reactor a few days after being restarted to reach full output, the company said.

Which sounds like good timing. The Japanese, much like Americans, appreciate air conditioning. More seriously, Japan’s industrial sector stands to be seriously hemmed in, though the story says this particular restart is more about the air conditioning, allowing Kansai Electric to just about meet its forecast of need output for the summer.

But it’s just the beginning.

Japanese media said leading candidates [to be brought back online] would be a reactor at Shikoku Electric Power’s Ikata plant in Ehime prefecture and two units at Hokkaido Electric Power’s Tomari plant on the northern island of Hokkaido.

Japan has not yet released in energy roadmap, expected sometime this summer. But it has already taken a larger interest in renewable energy sources.

Industry Minister Yukio Edano approved the introduction of feed-in tariffs (FIT), which means higher rates will be paid for renewable energy. The move could expand revenue from renewable generation and related equipment to more than $30 billion by 2016, brokerage CLSA estimates.

Whatever happens to the nuclear reactors, it certainly isn’t a bad idea to use what resource-poor Japan has on hand. The problem is that nuclear energy is relatively (a lot) less expensive.

The scheme requires Japanese utilities to buy electricity from renewable sources such as solar, wind and geothermal at pre-set premiums for up to 20 years. Costs will be passed on to consumers through higher bills.

We can’t guess what Japan will do with its energy mix. Using nuclear, wind and solar energy in tandem and shutting down fossil fuel plants will allow Japan to lower its carbon emissions. Other combinations will not.

Odd detail:

Wind power will be subsidized at least 23.1 yen per kwh, compared with as low as 4.87 euro cents (6 U.S. cents) in Germany.

That doesn’t tell you anything, does it? In fact, 23.1 yen is 29 cents – not good at all. This story from World Nuclear News provides some sense of relative cost within Japan:

Cost estimates made in 2004 by a Japanese government sub-committee put the cost of nuclear generation at ¥5.30 ($0.07) per kWh, by far the cheapest means of generating electricity, with oil at ¥10.70 ($0.14), coal at ¥5.70 ($0.07), gas at ¥6.20 ($0.08) and hydro at ¥11.90 ($0.16).

According to the story, the accident at Fukushima Daiichi raises that cost by, at most, another two cents per kWh. That makes coal and natural gas more competitive, but not renewable energy sources – wind energy not at all – certainly not with those subsides in place.

The O(h)I facility.

Ohi's phase-1 safety review was approved ages ago. Is there an online source for the approval status of the other Japanese reactors?

Japan almost religiously prides its scenic treasures, so I wonder how they're going to wrap themselves around windmills razing forests and mountainsides for noisy intermittent power. Vermont, take note!

A Design Team Pictures the Future of Nuclear Energy

For more than 100 years, the shape and location of human settlements has been defined in large part by energy and water. Cities grew up near natural resources like hydropower, and near water for agricultural, industrial and household use.

So what would the world look like with a new generation of small nuclear reactors that could provide abundant, clean energy for electricity, water pumping and desalination and industrial processes?

Hard to say with precision, but Third Way, the non-partisan think tank, asked the design team at the Washington, D.C. office of Gensler & Associates, an architecture and interior design firm that specializes in sustainable projects like a complex that houses the NFL’s Dallas Cowboys. The talented designers saw a blooming desert and a cozy arctic village, an old urban mill re-purposed as an energy producer, a data center that integrates solar panels on its sprawling flat roofs, a naval base and a humming transit hub.

In the converted mill, high temperat…

Sneak Peek

There's an invisible force powering and propelling our way of life.
It's all around us. You can't feel it. Smell it. Or taste it.
But it's there all the same. And if you look close enough, you can see all the amazing and wondrous things it does.
It not only powers our cities and towns.
And all the high-tech things we love.
It gives us the power to invent.
To explore.
To discover.
To create advanced technologies.
This invisible force creates jobs out of thin air.
It adds billions to our economy.
It's on even when we're not.
And stays on no matter what Mother Nature throws at it.
This invisible force takes us to the outer reaches of outer space.
And to the very depths of our oceans.
It brings us together. And it makes us better.
And most importantly, it has the power to do all this in our lifetime while barely leaving a trace.
Some people might say it's kind of unbelievable.
They wonder, what is this new power that does all these extraordinary things?

Seeing the Light on Nuclear Energy

If you think that there is plenty of electricity, that the air is clean enough and that nuclear power is a just one among many options for meeting human needs, then you are probably over-focused on the United States or Western Europe. Even then, you’d be wrong.

That’s the idea at the heart of a new book, “Seeing the Light: The Case for Nuclear Power in the 21st Century,” by Scott L. Montgomery, a geoscientist and energy expert, and Thomas Graham Jr., a retired ambassador and arms control expert.


Billions of people live in energy poverty, they write, and even those who don’t, those who live in places where there is always an electric outlet or a light switch handy, we need to unmake the last 200 years of energy history, and move to non-carbon sources. Energy is integral to our lives but the authors cite a World Health Organization estimate that more than 6.5 million people die each year from air pollution.  In addition, they say, the global climate is heading for ruinous instability.
