I have a question,not having a scientific mind. Before the Fukushima disaster there were 54 reactors on line in Japan, maybe not all running at the same time due to maintenance, but only producing 30% of Japans, electricity. My question, " 54 reactors, are they not sufficient to provide 100% of Japans needs of electricity." " and if so, shouldn't the cost to the consumer be a fraction of what is charged now " sorry thats 2 questions.

Minello. Japan has mountainous areas and lots of rivers. In some cases, the nuclear power plants are just too far from the people or factories that need the electricity. In those cases it is much more logical to produce local energy, rather than transport it over a huge distance. The problem is indeed that the power companies have neglected year after year after year to invest their profits in renewable energy on a decent scale, instead playing risky and short term thinking with the nuclear.

I have a question,not having a scientific mind. Before the Fukushima disaster there were 54 reactors on line in Japan, maybe not all running at the same time due to maintenance, but only producing 30% of Japans, electricity.

They produced about 30% but accounted for less than 25% of the generation capacity. Electricity production isn't about producing 100% all the time, it is about producing what you use when you use it. Nuclear provided the stable base load power, so the amount people use at night+ amount to charge certain other systems like pumped hydro. During peak, nuclear accounts for as little as 20%, but off-peak, it was over 80% in some places.

My question, " 54 reactors, are they not sufficient to provide 100% of Japans needs of electricity." " and if so, shouldn't the cost to the consumer be a fraction of what is charged now " sorry thats 2 questions.

First part, see above. Second part, no, it costs only 6 yen per kWh to produce nuclear (including transmission and insurance fees), 8-14 yen a kWh for fossil fuels (dirty coal is cheapest, then natural gas, clean coal, then oil), and a whopping 50-60 yen per kWh for solar. Since nuclear was the cheapest, the cost, even at 20-30% of total, is going to increase drastically (several percentage points).

The feed-in tariff (FIT) scheme requires utilities to buy electricity from renewable sources at pre-set premiums for up to 20 years. Costs will be passed on to consumers through higher bills to boost renewables, which apart from large hydro-electric dams now account for a mere 1 percent of Japan’s power supply.

FIT will cost the economy 100-400 trillion yen per percentage point increase in renewable as a function of total energy production per year. And that's in the tariff alone, the cost of installing that much solar would cost another 300 trillion or more. I doubt that the government thought it through, because that is up to twice the GDP of Japan, and no less than half the GDP. I don't care who you pass on the bill to, the economy simply can't afford it.

Japan lags way behind internationally in renewables after neglecting the sector for years to concentrate on nuclear power.

Clearly the writer has agendas here. Japan lags simply as a function of economics and geography. Large scale solar panels just aren't possible at reasonable costs. Hence Japan has focused on small footprint power stations like coal, gas, oil, and nuclear, simply because they don't have enough space.

Globally, renewable energy accounted for around 20 percent of electricity production in 2011, according to Renewable Energy Policy for the 21st Century, with around 15 percent of that coming from hydropower.

Hydro is considered separate in Japan, and even Japan has a fairly sizable amount of production where they can. The quote here probably includes non-commercial production, and is overestimating the percentage produced because of that.

With the cost of the nuclear disaster which will be in tens of trillions yen, and also the cost of reactor safety updates, will greatly increase the cost of nuclear energy, which still receives very large gov't subsidies, including about 400 billion yen every year for energy R&D, and the gov't pays billions every year to those prefectures which have atomic power plants.

The prefectures have also received brides from the power companies, to keep them sweet on atomic power. Except the people living in Fukushima are no longer feeling sweet, highlighted by the prefecture governor who stated "nuclear power plants in Fukushima will never operate again. Fukushima is turning to renewable energy, which won't replace the energy loss from both the Fukushima atomic plants. The first Fukushima will never operate again, and the second plant might also be refused permission to start up again.

The gov't have hinted, that when its new energy policy is released, future use of nuclear energy will be limited to 15% of total power. But we'll have to wait for the report to know the real details.

In answer to a comment above, prior to the 3/11 nuclear disaster, 34 reactors were operating, which was about the average number. Its mandatory that all reactors are shut down every 13 months for inspection and maintenance.

The Oi reactors will run until autumn 2013, before reaching the mandatory shutdown.

Japan needs about 250GW of power, prior to 3/11, nuclear energy was generating about 48GW.

basroil,

FIT will cost the economy 100-400 trillion yen per percentage point increase in renewable as a function of total energy production per year. And that's in the tariff alone, the cost of installing that much solar would cost another 300 trillion or more. I doubt that the government thought it through, because that is up to twice the GDP of Japan, and no less than half the GDP. I don't care who you pass on the bill to, the economy simply can't afford it.

When you pulled those figures out of your hat, did a white rabbit jump out too?

A rough calculation. ¥400 trillion would equal to something like 10 billion kWh? The cost of installing solar ¥300 trillion? At appox price of ¥1 million per 2 sq m panel would equal 300 million panels?

Clearly the writer has agendas here. 

Wow there's a case of the kettle calling the pot black. Since you started posting on this forum who have had an agenda to defend the use of nuclear energy at all cost. Interesting when it comes to the cost of the nuclear disaster, which I have stated many times, will be in access of ¥30 trillion over the next 30 years, you down play that figure, saying it will only cost a couple of trillion, ignoring the figures to date that the gov't have paid ¥3.5 trillion directly to TEPCO, and there are compensation claims of almost ¥5 trillion, not including buying any land or property inside the no-go zone.

When it comes to radiation you play that one down, stating that most the no-go zone is safe from radiation.

When it comes to the increase in costs of nuclear energy because of the cost of the disaster, the cost of improving atomic plant safety, and the cost of long term shortage for spend nuclear fuel, you play down those figures too.

But when it comes to the cost of FIT and the price of solar power, you play those figures up and over the moon. Then you accuse the "writer of having an agenda?"

Where did you get your figures from?

Based on the facts zichi presented, nuclear is a lose lose situation. Way.

What "facts"? The estimated peak power Japan needs? That's actually more than the official estimates, and in fact more than Japan ever had! The actual demand numbers are about 180GW for summer, 170GW or so after "savings". Japan's capacity is only about 210GW, maybe 220-230GW if you include both nuclear AND long-idled plants. Check http://eneken.ieej.or.jp/data/3938.pdf .

Lets also look at his 400 billion R&D budget. Assuming that is correct, which we can't be certain of, we can see the cost-benefit using the expected increase in prices vs the R&D cost. Average operational costs per kWh are expected to rise by 3.7 yen per kWh, and either customers pay it or the companies pay it. If the companies pay it (which they have so far), it would amount to about 3-3.7 trillion yen in lost profit. From a 40.7% corporate tax, we are looking at over a trillion yen (almost 1.5 trillion) in lost tax revenues. For those figures, nuclear R&D is a very profitable investment, returning 3 yen for every yen you put in. Even if corporate tax was only 20%, they would get much more in taxes than they give out.

basroil,

it's been well documented that the power companies gave addition money to nuke villages by building sports stadiums, like the one in Fukushima which TEPCO is now using for its own J Village. Also large shopping malls. Direct bribes to elected officilals, but I'll have to check on whether they also received brides too

-1 ( +5 / -6 )

basroil,

Lets also look at his 400 billion R&D budget.

The law dates back to 1974. In 2010, the gov't gave .¥500 billion for energy R&D, with more than 90% of it going to the nuke village, and the rest to renewable energy.

That should continue with 90% of the ¥500 billion going to renewable energy, and the other ¥100 billion to research safety of atomic power plants.

-1 ( +5 / -6 )

It is not a question of "public safety fears" on one side and "worries about high electricity costs costs on the other" -that is far too simplistic a debate. The issue, considered by and reported on, by the Japanese parliament summed up thus:

"The Fukushima nuclear meltdown was a “man-made” disaster caused in large part by Japan’s culture of deference and collusion between the government, regulators and the plant operator."

Thus, it can be seen that the industry is unable to regulate itself. The most dangerous power known to man is being handled by liars and incompetents on an island which sits on numerous fault lines,likely to destroy any structure that happens to be above them.

The effects of the fallout have been seen in plants and animals and are increasingly being seen in humans.

Cancers,heart disease,infertility and genetic generational physical abnormalities are the results of errant nuclear power.

Fukushima still has a highly radioactive environment that cannot be contained and is still poisoning us-presently there are no remedies to prevent this.

Steps to continue with nuclear power which is already killing us all to some degree or another is abhorrent!

There was a small issue in the change up between yen and dollar rates, just divide everything by 80. I'm tired, been busy with work, I can make a slipup every once in a while. Interestingly, the second post looks about right, probably because all of the data was in yen.

Cost of Nuclear Power in Japan

The government's nuclear energy budget hovers around 500 billion yen ($4.5b). Private R&D investment (27 billion yen ($247m) in 2003) is well below 10% of government spending on nuclear energy, so clearly the government has provided huge subsidies to the nuclear industry. Without these subsidies, the industry wouldn't have survived.

http://cnic.jp/english/newsletter/nit113/nit113articles/nit113cost.html

In Fukui where the Oi reactors are located, there are about 13/14 reactors. The nuke industry received something like ¥380 billion in grants when they were built. Every atomic power plant has been built using tax payers money, not the entire cost, but very large grants.

Each year around 154 billion yen ($1.4 billion) is provided to local self-governing bodies. It is used for such things as the construction of roads, government office buildings, libraries and hospitals.

-1 ( +5 / -6 )

The Fukushima LEVEL 7 nuclear disaster was declared man made, but we won't see any real increases in the safety of atomic reactors for at least 5 years, which will be the time span most of the power companies will need to complete the work which will cost more than ¥1.5 trillion and maybe as much as ¥200 million per reactor, which would not include the cost of associated work, like building earthquake and radiation proof offsite control centers.

By 2030, the cost of nuclear energy will be 3 or 4 times the price of energy from wind, solar, biomass.... We would still be left with the problem of storing the nuclear waste.

If all the reactors were decommisioned it will cost about ¥5 trillion. The total worth of the 9 mainland power companies is about ¥4.5 trillion, and three of those would go bankrupt. So I guess the taxpayer again, will end up paying these costs.

Using what math here? You yourself stated 150 trillion not long ago. 5 trillion over 30 years (minimum decommission time) is 167 billion yen a year. Oi 3-4 alone makes 10TWh a year on average including downtime from Fukushima. Even assuming that Oi is the only plant (and since 3-4 are 13 years newer than 1-2, they won't be scheduled for shutdown until past 2025), the "price for nuclear" is increased by 16 yen to 22 yen per kWh. That's still half to a third of the expected cost for a new solar panel installation, and about the same as high output wind sites. Japan makes nowhere near enough food for biomass, so unless you want 1000 yen slices of bread lets just forget that silly idea.

If they go back to 15% like they said, you increase the cost by 1 yen per kWh at most, and (assuming prices are fixed into the future), it would still be cheaper than coal, gas, oil, and the "renewables" by a fair margin. And these numbers assume just 50% capacity rather than 85% that is the world average.

Second part, no, it costs only 6 yen per kWh to produce nuclear (including transmission and insurance fees), 8-14 yen a kWh for fossil fuels (dirty coal is cheapest, then natural gas, clean coal, then oil), and a whopping 50-60 yen per kWh for solar. Since nuclear was the cheapest, the cost, even at 20-30% of total, is going to increase drastically (several percentage points).

How predictable: more distrotion disguised as information. It is so easy to just repeat the standard anwer given by the self-interested, pro-nuclear industry instead of doing some critical thinking. Did this information come right off of the Tepco homepage?

If we calculate the true cost of nuclear energy, we must include all the externalities, such as the decades-long payments to deal with the man-made nuclear disaster, as well as the cost of waste storage, decommissioning and the lost opportunity costs of not investing in renewable energy and energy effienct technologies? Also, the cost of solar keeps going down as the technology improves and the demand increases.

You are seriously misquoting me? I did state that many have estimated the cost of the nuclear disaster will be more than ¥30 trillion over 30 years,I also previuosly stated a Tokyo University professor put the figure at ¥50 trillion. I think those figures will be accurate in the end. I also provided a link to the claim by the professor, but you already know all of this.

The cost of decommissioning an atomic power plant which has experienced a LEVEL 7 nuclear disaster will be much less so the figure of ¥5 trillion to decommossion the other reactors and atomic power plants still stands.

-1 ( +5 / -6 )

The cost of nuclear energy will rise ¥1.6/kWh for every ¥1 trillion spent on the Fukushima nuclear disaster. ¥30 trillion will increase costs to ¥48/kWh, plus the basic cost of nuclear energy, plus the cost of improving atomic plant safety standards, plus the cost of long term storage of nuclear waste plus the costs of decommissioning plus the costs of all the subsidies and grants.

The myth of nuclear energy being safe, clean and cheap, is busted!

zichiJul. 06, 2012 - 01:50PM JST

The cost of nuclear energy will rise ¥1.6/kWh for every ¥1 trillion spent on the Fukushima nuclear disaster. ¥30 trillion will increase costs to ¥48/kWh

But if you do the calculations it actually amounts to 3.3yen per kWh per trillion if ONLY Oi 3-4 are restarted at 50%, or 0.25 yen per kWh per trillion if 15% is nuclear. For $30 trillion in costs (about 500 times more than official estimates), you are looking at 7.5 yen/kWh, which brings the cost up to 14 yen/kWh which is just about the same as LNG, so very cheap comparatively.

My numbers are simple 30 year amortization, which likely are actually too high year to year since you stated 5 trillion (17%) would be decommissioning which takes place no earlier than 30 years.

Do tell us where those numbers are, I haven't seen them anywhere but in activist blogs.

The figure from the gov't expert panel of increase in costs of nuclear energy was based on the total amount of power generated by nuclear energy prior to the 3/11 nuclear disaster. That figure of ¥1.6/kWh for every ¥1 trillion cost of the nuclear disaster is more than likely to increase in the post nuclear disaster since the gov't have hinted, future use of nuclear energy could be limited to15%, or about half of what was generated before.

The figure could easily double to ¥3.2/kWh for every ¥1 trillion cost of the nuclear disaster. If the eventual cost of the disaster is ¥30 trillion, then the cost of nuclear energy would rise by ¥96/kWh, on top of the basic cost of generating from nuclear energy.

You fiddle the figures to suit your agenda, up the costs of solar power up over the moon, down the real cost of nuclear energy, down the radiation levels.....need I go on? Most of us are very clear what your agenda is.

Added to the cost of nuclear energy will be all the costs of the atomic power plants which are now idle and not earning the power companies a single yen. But they still have to shell out their massive overheads to maintain those plants, and pay the wages of thousands of staff and workers.

I just hope at least the power companies are using the down time wisely to check out their plants. Is that happening at the atomic plant you work in Hokkaido?

Modern DATA centers are power hungry. There's a DATA center just outside of Bristol City in the UK which uses more power than many cities.

This morning I was reading an interesting article about AOL, anyone remember them? Thought they might have disappeared? Anyway, AOL have come up with a new idea for DATA storage. It about the size of a normal fridge and does not even need to be located inside one of those super high tech DATA centers. Just used a domestic power point. No vast cooling systems, can be located on a roof, in a garden. This could be a winner for AOL and save a whole load of greenhouse gases from power generation.

This kind of ideas along with the likes of Bloom Energy Servers can help to reduce power demand greatly, or like the new cooling venting machine Coke has come up with. Cools the drinks only over night and then the drinks are cool for 16 hours.

Saving power,and how we have been using power is now an important aspect of any energy research here in Japan. The more we save, or use efficiently, the less power that needs to be generated.

Bloom servers are nice, with good theoretical efficiency, nice and compact. But only in California. While they have 10 cents a kWh there, you can expect 1.5-3x that here, so still more expensive than coal or nuclear here. Much better idea than solar though, but also kills the Kyoto protocol.

I guess by the end of your comment, "kills the Kyoto protocol" you have even bothered to read up what Bloom Energy Servers are, because they produce zero emissions.

The actual cost of the kWh depends entirely on the source of energy you buy. Can be used with LNG or biogas. At Apple's new DATA center, it has installed both solar panels and Bloom Energy Servers running on biogas. If they used LNG here in Japan, the cost per kWh would be cheaper than the cost per kWh from a gas fired power plant, plus unlike those, there would also be zero emissions which even beats nuclear energy.

Fortune 500 companies across the whole of America are installing Bloom Energy Servers to generate up to 30% of their total power needs. I'm not sure why you would think they would only be limited to California?

zichi stated that the Bloom Boxes were fed Bio Gas, which means it is a zero sum game for environmental CO2.

Because they use natural gas, they produce CO2. They output as much CO2 as a regular gas turbine for about the same energy.

Not completely true they are much more efficient than a gas turbine, so even when you run them on LNG or some other fossil fuel they output much less CO2 per KW than a traditional thermal power plant or gas turbine.

The get something like 50% to 55% conversion efficiency. with 0.8 pounds/kWh CO2 ouput for LNG , Compared electricity from coal-fired plants (2 lbs/kWh) or natural gas plants (roughly 1.3 lbs/kWh).

Once again, with Bio Gas the net output becomes 0.

CAN be bio gas, usually just regular natural gas, and in Japan, would 100% be natural gas since bio-gas fuels are economically impossible. Bio anything is NOT net zero, as you need more CO2 to produce the feed than you save.

Nuclear on the other hand IS zero CO2 production during energy generation. Wind and solar too

Biogas is frequently produced by waste products, whether it's used or not. Here in Kobe City, biogas is produced from waste and used to run a number of public buses.

http://martinjapan.blogspot.jp/2010/09/biogas-as-fuel-or-as-city-gas.html

Power generation from stockfarming waste, sewage sludge, food waste and biomass is in 2007 increased to over  40 plants, build and under construction with a electric power generation over 9 million kWh. More then 350 sewage treatment plants working with anaerobic digestion facilities of the sludge ,with more plants developing power generation facilities from 30 today and 100 million kWh per year.

http://www.prlog.org/10069177-booming-biogas-plant-markets-in-japan-for-biowaste-agriculture-and-sewage-plants.html

So if DATA centers were to use Bloom Energy Servers with biogas, the new AOL style DATA servers and provide their workers with drinks from new style Coke vending machines, they could greatly reduce the size of the building, the energy needed and greatly reduce overheads.

The gov't needs to remove the monopoly that for decades the power companies have held. A monopoly on both power generation and on power supply.

It goes against common sense that the only company in Kansai which can both generate power and supply it, is the Kansai power company. There's needs to be a separation of companies which generate power from other companies which supply customers. In all countries which have removed this type of monopoly, the customer has benefitted with lower power charges.

There are basically two grids in the country, one for the east and the other for the west. I see no reason why there can't be better use of smart grid systems which can move power to were it's needed. Someone in Kansai, could be buying power from Kyushu.

The gov't needs an expert investigation into power generation and what are the best energies to use. If nuclear power is limited to 15%, that still leaves the other 85%. Which renewable energies,like geothermal can be increased, how much power can be generated from wind, solar, biomass. What other alternatives are on the horizon.

Even the jellyfish is anti-nuclear these days in Japan. A large number of jellyfish clogged up the water intake at Oi Nuclear Power Plant, and KEPCO may be forced to delay the full operation of Reactor 3.

Odd, jellyfish are typically going after places with high salinity and temperature, yet the water there shouldn't be that warm yet. Easy enough to clean up though, and not that time sensitive.

The gov't needs to remove the monopoly that for decades the power companies have held. A monopoly on both power generation and on power supply.

It goes against common sense that the only company in Kansai which can both generate power and supply it, is the Kansai power company. There's needs to be a separation of companies which generate power from other companies which supply customers. In all countries which have removed this type of monopoly, the customer has benefitted with lower power charges.

I agree that the monopoly is a bad idea for residential customers, since they get stuck with huge administrative fees on top of production and transmission (which are higher than major lots). At the same time, unless they have a unified power management system, it will end up like the USA, where a few downed power lines can shut down thousands of houses, and a blown substation can turn off electricity to half the country. Even with that issue, some sort of deregulation is needed, especially if it allows people to decide the source of their power (people who want solar can buy it, those that want the cheapest price can get the cheapest price.

There are basically two grids in the country, one for the east and the other for the west. I see no reason why there can't be better use of smart grid systems which can move power to were it's needed. Someone in Kansai, could be buying power from Kyushu.

There was some talks about adding more 765kV lines to allow the companies to share. Problem is that they all peak around the same time, and all are expecting to be at the margin if temperatures hit 35 for an extended time.

The gov't needs an expert investigation into power generation and what are the best energies to use. If nuclear power is limited to 15%, that still leaves the other 85%. Which renewable energies,like geothermal can be increased, how much power can be generated from wind, solar, biomass. What other alternatives are on the horizon.

Again, biomass doesn't make sense for Japan, since the primary source would be burnable trash, but that has too low a energy density to be viable outside major cities. Natural source geothermal is also difficult because Japan has pretty much turned all the best places into onsen, and pumped geothermal is very bad for the environment (heavy metal pollution and earthquakes). Wind/solar take too much space, about 58km^2 per GW for solar and five times that for wind.

But they should research future energy production methods, since an energy revolution would not only bring cheap power, but also be a great export. I just can't see current alternative energy methods being useful for Japan (usually cost ratio is far too large and will drive the country further into debt)
