Japan plans 100% renewable energy for Fukushima prefecture by 2040

Japan aims to power region, scene of 2011 meltdown, with 100% renewable energy by 2040, Justin McCurry in Tokyo , 6 Jan 2020
Fukushima is planning to transform itself into a renewable energy hub, almost nine years after it became the scene of the world’s worst nuclear accident for a quarter of a century.
The prefecture in north-east Japan will forever be associated with the triple meltdown at the Fukushima Daiichi nuclear power plant on 11 March 2011, but in an ambitious project the local government has vowed to power the region with 100% renewable energy by 2040, compared with 40% today.
The 2011 accident, triggered by a powerful earthquake and tsunami, sent large quantities of radiation into the atmosphere and forced the evacuation of more than 150,000 residents.
The 300bn yen ($2.75bn) project, whose sponsors include the government-owned Development Bank of Japan and Mizuho Bank, will involve the construction of 11 solar and 10 wind farms on abandoned farmland and in mountainous areas by the end of March 2024, according to the Nikkei Asian Review.
A 80km grid will connect Fukushima’s power generation with the Tokyo metropolitan area, once heavily dependent on nuclear energy produced at the prefecture’s two atomic plants. When completed, the project will generate up to 600 megawatts of electricity, roughly two-thirds the output of an average nuclear power plant.
Despite the Fukushima disaster, the world’s worst nuclear accident since Chernobyl in 1986, Japan’s conservative government is pushing to restart idle reactors.
It wants nuclear power, which generated almost a third of the country’s power before Fukushima, to make up between 20% and 22% of its overall energy mix by 2030, drawing criticism from campaigners who say nuclear plants pose a danger given the country’s vulnerability to earthquakes and tsunami.
All of Japan’s 54 reactors were shut down after the Fukushima meltdown. Nine reactors are in operation today, having passed stringent safety checks introduced after the disaster.
Renewables accounted for 17.4% of Japan’s energy mix in 2018, according to the Institute for Sustainable Energy Policies, well below countries in Europe. The government iaims to increase this to between 22% and 24% by 2030 a target the prime minister, Shinzo Abe, has described as ambitious but which climate campaigners criticise as insufficient.
Abe insists nuclear energy will help Japan achieve its carbon dioxide emissions targets and reduce its dependence on imported gas and oil, but his recently appointed environment minister, Shinjiro Koizumi, has called for the country’s nuclear reactors to be scrapped to prevent a repeat of the Fukushima disaster.
“We will be doomed if we allow another nuclear accident to occur. We never know when we’ll have an earthquake,” Koizumi said when he joined Abe’s cabinet in September.
The government is unlikely to meet its target of 30 reactor restarts by 2030 given strong local opposition and legal challenges.
Japan faces mounting international criticism over its dependence on imported coal and natural gas. It received the “fossil of the day” award from the Climate Action Network at last month’s UN climate change conference in Madrid after its industry minister announced plans to continue using coal-fired power.
Japan is the third-biggest importer of coal after India and China, according to the US Energy Information Administration. Its megabanks have been urged to end their financing of coal-fired plants in Vietnam and other developing countries in Asia.
How Ontario can get out of nuclear power, and reduce carbon emissions
As researchers who have examined the economics of electricity generation in Ontario and elsewhere, we argue that this decision is wasteful and ill-advised, and the unnecessary cost differential will rise further in the future.
One concern about renewables has been the intermittency of these energy sources. But studies have shown it’s feasible to have an all-renewable electric grid.
These feasibility studies, however, are always location specific. In that spirit, we have carried out detailed modelling and found that it’s possible to meet Ontario’s electricity demands throughout the year with just a combination of renewables, including hydropower, and storing electricity in batteries.
We also found that dealing with the intermittency of wind and solar energy by adding batteries would be more economical than refurbishing nuclear plants in the foreseeable future, well before the current refurbishment projects are completed.
That’s because of the expected decline in the cost of batteries used to store the electricity during the hours when the wind is blowing or the sun is shining in order to supply electricity during the periods when they aren’t. The cost of different kinds of battery technologies, such as lithium-ion or flow batteries, have come down rapidly in recent years.
Essential results
In all scenarios, the bulk of the demand was met by solar and wind power, with a lower fraction met by hydropower. Even in the scenarios with no batteries, less than 20 per cent of the electricity demand was met by nuclear power…….
In summary, our results show that for reasonable assumptions about future battery costs and the current price tag for solar and wind power, scenarios involving nuclear power are more than 20 per cent higher than the cheapest scenario involving only batteries, solar, wind and the current hydropower capacity. …
nuclear power isn’t needed to meet Ontario’s electricity needs. And the absence of nuclear power won’t have any impact on emissions in Ontario’s energy sector.https://theconversation.com/ontario-can-phase-out-nuclear-and-avoid-increased-carbon-emissions-128854?fbclid=IwAR20ANW_yAmpR7zZVw113hUp9bl7Xt2h0v1XiB1K815lFIKctZiaR8xB5Ew
The rise and rise of global offshore wind capacity

Renew Extra 4th Jan 2020, Dave Elliott: The International Energy Agency says global offshore wind capacity may increase 15-fold and attract around $1 trillion of cumulative investment by 2040, driven by falling costs, supportive government policies and some remarkable technological progress, such as larger turbines and floating foundations.

Egypt’s solar energy success
Reuters 17th Dec 2019, Near the southern Egyptian city of Aswan, a swathe of photovoltaic solarpanels spreads over an area of desert so large it is clearly visible from space. Designed to anchor a renewable energy sector by attracting foreign and domestic private-sector developers and financial backers, the plant now provides nearly 1.5 GW to Egypt’s national grid and has brought down the price of solar energy at a time when the government is phasing out electricity subsidies.

In France, over the next decade renewable energy is ‘on track to overtake nuclear’
Renewables ‘on track to overtake nuclear’ in France https://www.powerengineeringint.com/2019/12/16/renewables-on-track-to-overtake-nuclear-in-france/ Kelvin Ross A new study claims that renewables are on track to overtake nuclear power as the dominant energy source in France in the next decade.The share of renewables in France will hit 42.9 per cent of the country’s power mix by 2023, up from 19.9 per cent in 2018, according to analytics company GlobalData.
And the research suggests that renewables will continue to rise as nuclear reactors come offline. The report examining France’s power outlook to 2030 reveals that in 2018 nuclear power dominated the capacity mix by 47.2 per cent, followed by renewables, hydropower and thermal power. In the non-hydro renewable energy mix, wind contributed 56.7 per cent followed by solar PV with 35.6. GlobalData analyst Piyali Das said that France “is aiming to boost the renewable energy sources through tender mechanism. Renewable power sources are expected to increase at a compound annual growth rate of 8.9 per cent between 2019 and 2030 with a net capacity addition of around 50 GW. “Installed capacity for onshore wind will double from its current levels of 15.1 GW by 2026, and to support the expansion the government has announced doubling of the renewable energy budget. Solar PV is not behind by much in terms of growth and will witness an addition of more than 24 GW during the same period.” Das said that in the long-term, the French government has decided to cut down its fossil fuel dependency and is replacing coal and oil power stations with gas-fired plants. The government also has wants to reduce nuclear generation to 50 per cent of net generation by 2035, with a plan to decommission around 14 reactors by 2035 and fill the gap with renewable sources. “To date the development of renewable energy is largely supported by public support mechanisms,” explained Das. “These mechanisms finance the difference between the remuneration of their production on the wholesale market and the purchasing price guaranteed by the state to the renewable producer. |

China’s $2.5bn renewables investment in Inner Mongolia

China’s nuclear power company plans $2.5bn renewables investment in Inner Mongolia http://www.globalconstructionreview.com/news/chinas-nuclear-power-company-plans-25bn-renewables/, 22 November 2019 | By GCR Staff
China General Nuclear Power Group (CGN) is preparing to invest $2.5bn in renewables generation capacity in its northern province of Inner Mongolia, including a 1GW solar facility and a 2GW wind farm, according to a report in PV Magazine. The investment aims to capitalise on the climate of the region, which combines strong and steady winds with up to 3,400 hours of sunshine a year. CGN was founded in 1994 to operate nuclear power plants, but has since built up a domestic portfolio of renewable assets, including 9.1GW of wind capacity and 1.7GW of solar. The wind turbines are to be installed near the city of Ulanchabu, which will also make the turbines. Administrative work will be carried out in the first half of next year with construction scheduled to begin in August and complete in 2021. The Inner Mongolia Solar Energy Industry Association says the transmission lines required to bring the electricity from the sparsely populated north have already been built. At the beginning of this year, the State Power Investment Corporation (Spic), one of China’s top five energy generators, announced plans to build a 6GW windfarm close to China’s border with Mongolia. Spic announced that is has received planning approval for its project from the Ulanqab Municipal Development of Inner Mongolia. If it goes ahead, it would install turbines across an area of 3,800 square kilometres, roughly the same size as the UK county of Suffolk, at a construction cost of about $6.8bn. |

In Germany , renewables replace nuclear and lower emissions simultaneously
Renewables replace nuclear and lower emissions simultaneously Energy Transmission, by Craig Morris, 20 Nov 2019
A myth is haunting the English-speaking world: Germany allegedly shows that emissions rise because renewables can’t replace nuclear – and that France is right to stick with nuclear. What do the data show? Craig Morris reports
It’s not just trolls: Cambridge professors are saying it, and top US journalists are saying it, and a US presidential candidate told it to the New York Times:
“Germany initially set out to close all of its nuclear reactors by 2022, but as a result, they are now likely to miss their emissions reduction targets. And France is now considering options to extend the life of many of its older nuclear power plants.”
— US presidential candidate Marianne Williamson in the New York Times
What’s worse, US policymakers are saying it. Five US states now subsidize nuclear to keep reactors from closing, and it’s possible that all of them have done so based on this incorrect assumption. It happened years ago in New York State with explicit reference to German emissions allegedly rising because of the phase-out, it then happened in Illinois, and as one press report from Ohio put it this year when the new nuclear subsidy was announced:
The experience of Germany was repeatedly used as an example of what might happen in Ohio. Germany decommissioned its nuclear plants in favor of an all-renewable strategy. Electricity prices spiked and carbon pollution spiked, in part because of the ramping up of fossil-fuel plants to compensate for when wind and solar faltered.
“If the studies are correct, the Germans must not know how to do this,” Mr. Randazzo [chairman of the Public Utilities Commission of Ohio] said.
“If the studies are correct” indeed: So do Germany and France show that climate change requires nuclear, as Williamson says? Let’s start with France………..
France’s concern is theoretical: they didn’t actually close any reactors and try to replace the power with renewables. Rather, the French left nuclear on, and renewables hardly grew; solar (1.9%) and wind (5.1%) made up a mere 7.5% of French power supply in 2018. (In Germany, solar alone covered 7.7% of demand in 2018, with wind adding another 18.7% for a total of 26.4%). But in Germany, replacing nuclear with renewables isn’t just a postponed political ambition; it’s happening. So what do we know?
Germany emissions during the nuclear phaseout
In 2011, eight of Germany’s 17 reactors were closed. From 2010-2017, emissions in the power sector fell by more than 15%. For 2018, the power sector numbers are not yet in, but emissions from the energy sector fell by nearly two percentage points. And to date in 2019, renewables have nearly reached 50% of power supply. Germany now has some 210 TWh of non-hydro renewable power, far more than the record level of 171 TWh in 2001 for nuclear. Since 2010, renewable power has grown nearly twice as fast as nuclear shrank. Some nine tenths of it is wind and solar alone. Clearly, Germany shows that renewables can reduce emissions during a nuclear phaseout.
At this point, I hear objections. The first: “but Germany is going to miss its 2020 climate target!” Yes, it is expected to reach a 32% emissions reduction, not 40% relative to 1990 (French emissions fell by 15% from 1990-2017 in comparison, albeit from a much lower level thanks to nuclear). But the Germans don’t see the power sector as the main problem. As Deutsche Bank recently put it, “So far, Germany’s efforts… have focused on the electricity sector. However, attention is increasingly shifting towards the transport sector and its steadily rising carbon emissions.” Former Environmental Minister and Christian Democrat Klaus Töpfer recently worded the German consensus well: “We have the highest taxes on electricity although we have reduced emissions there the most.” That’s right: Germany has performed best in the sector where it has removed nuclear and worse in sectors where nuclear plays little or no role: mobility, agriculture, and heat.
The second objection is generally: “Germany would have lowered emissions even more if it had phased out coal, not nuclear.” That’s a fine thing to discuss, but it only moves us from a falsehood (“German phaseout raised emissions”) to revisionist history – not to facts. The revisionist historians act as though renewables would have been built anyway if nuclear remained online. As I wrote in my 50-page paper entitled Can reactors react (2018), the Germans argued a decade ago that renewables were unlikely to be built if nuclear stayed online.
What do the French and German cases show about how much renewable energy gets added when nuclear stays online? The French are also failing to add new nuclear as quickly as its own power company closes old reactors it wishes to keep on. From 2010-2018, wind and solar grew by 27.4 TWh in France, while nuclear shrank by 14.7 TWh (and demand stayed flat). During the same timeframe in Germany, nuclear shrank by 64.6 TWh – but solar and wind alone grew by 91.8 TWh.
The current French situation suggests that, if you remain committed to nuclear, nuclear power nonetheless shrinks; to make matters worse, the growth of renewables struggles to close the gap. Germany suggests that, if you stick with renewables and phase out nuclear, renewables growth outstrips the drop in nuclear nearly twofold, and you reduce emissions by 2 percentage points annually in the power sector. https://energytransition.org/2019/11/renewables-replace-nuclear-and-lower-emissions-simultaneously/
If You Can’t Do Nuclear, Try (Concentrating) Solar Power Instead
|
If You Can’t Do Nuclear, Try (Concentrating) Solar Power Instead, https://cleantechnica.com/2019/11/19/concentrating-solar-power-breakthrough/ Some great news for concentrating solar power fans sailed in over the transom this morning. Mega wealthy person and famed US investor Bill Gates may be chasing the nuclear unicorn with his startup Terrapower, but meanwhile his other startup Heliogen — his secret one! — has just burst out of stealth mode with a new concentrating solar power breakthrough in its pocket.
A Concentrating Solar Power Breakthrough Grows In Lancaster, CAWhile TerraPower has been pitching nukes, the Heliogen research team has been hammering away in deepest secrecy at its research facility in Lancaster, California, with the aim of developing a concentrating solar power system that can deliver temperatures of more than 1,000 degrees Celsius.
Reading between the lines of Heliogen’s first ever press release, that puts the new solar system in direct competition with fossil fuels for high-heat industrial processes including cement and steel production. If all goes according to plan, the new system will also breathe new, lower-carbon life into the petrochemical industry. That’s great news for ExxonMobil and other petroleum (and natural gas) stakeholders, though it’s not so great news for the “keep it in the ground” approach to averting climate global disaster. The Concentrating Solar Power SolutionA typical concentrating solar power system works by collecting sunlight from arrays of specialized mirrors called heliostats (so Heliogen, get it?), and focusing the energy on a central point, where it heats molten salt or another medium, which then gets put to use. Boiling water for steam to run a generator is one such example. If that sounds complicated, it is. Concentrating solar power has had its critics in past years, mainly due to its relatively high cost and complexity. Nevertheless, the Department of Energy has been a big supporter of the technology here in the US, and it has been catching on elsewhere around the globe as the technology improves and costs come down. The Energy Department has also been zeroing in on research that leads to new record-setting heat levels, just as Heliogen is claiming. Here’s Heliogen on that topic: “Previous commercial concentrating solar thermal systems have been designed to reach temperatures of up to only 565 degrees Celsius – useful for power generation, but insufficient for many industrial processes. Many of these processes require much higher temperatures, which have traditionally been reached through the burning of fossil fuels.” That’s nothing. Heliogen is looking at temperatures up to 1,500 degrees. If you’re thinking what Heliogen is thinking, run right out and buy yourself a cigar. Among other uses, the technology could be deployed to “split” hydrogen from water. Hydrogen is a zero emission fuel but the primary source of hydrogen today is fossil natural gas, so the prospect of switching to water as a feedstock is a big deal. In terms of staving off catastrophic climate change, devoting energy to water-splitting systems makes sense only if the energy comes from renewable resources like solar, so if you hear the sound of popping in the distance, that would be renewable hydrogen fans breaking out the bubbly in celebration. How Does It Work?So far so good, but the devil is in the details. Other teams are pursuing high heat solar power systems. What puts Heliogen ahead of the rest of the concentrating solar power pack? The company isn’t saying much, except that it has something to do with an “advanced computer vision software to hyper-accurately align a large array of mirrors to reflect sunlight to a single target.” So far that sounds like a typical concentrating solar power system, with an extra punch provided by maneuvering the array of heliostats with extreme accuracy, enabling them to reflect more sunlight than other systems. There is probably a lot more to the picture, but that’s all Heliogen is giving out for now. Come to think of it, though, Heliogen has something in common with another company that has a concentrating solar power research site in Lancaster, California, called Edisun Microgrids. The thing in common is visionary innovator Bill Gross, who is listed as the CEO of Edisun, and who is also the CEO and co-founder of Heliogen. Gross has several other solar startups under his belt, but let’s zero in on Edisun. Last spring the Energy Department included Edisun in a group of research teams aiming to bring down the cost of concentrating solar power. Here’s the rundown from the Energy Department: “Traditional cost reduction strategies have focused on developing larger heliostats with more mirror surface area on each unit, making the mirrors even more susceptible to wind. This project will pair smaller mirrors that can more precisely track the sun with an inexpensive novel gear train as the foundation of the heliostat.” Stay tuned as CleanTechnica checks in with Heliogen for more details on its technology. Whatever Happened To TerraPower?Meanwhile, speaking of arrays, Heliogen has an impressive array of researchers, partners, and investors behind it, but Bill Gates sticks out in terms of name recognition so let’s hear what he has to say (via Heliogen’s press release): “…If we’re going to get to zero-carbon emissions overall, we have a lot of inventing to do. I’m pleased to have been an early backer of Bill Gross’s novel solar concentration technology. Its capacity to achieve the high temperatures required for these processes is a promising development in the quest to one day replace fossil fuel.” So, where does that leave TerraPower? The nuclear industry still has potential for growth in some parts of the world. TerraPower initially had China in its sights, although that avenue has reportedly been closed, at least temporarily, due to the President* Trump’s trade policies. Here in the US the prospects for finding news sites for nuclear power plants are zero to none within the foreseeable future, despite an assist from President* Trump’s so-named Affordable Clean Energy plan. Nevertheless, there are still 98 nuclear power plants in the US. Some of them could potentially house new technology as their licenses come up for renewal. As of last year the Energy Department was still cheerleading for TerraPower’s molten salt nuclear technology, and TerraPower continues to soldier on with R&D. The company has been working on a lab expansion and last September it also passed an important milestone in its work with the Energy Department’s Idaho National Laboratory. Since some concentrating solar systems also use molten salt as a medium, it’s also possible that some of TerraPower’s R&D could transfer to the concentrating solar power field, even if the nuclear thing doesn’t work out so well. |

Nuclear power allows climate change to speed up, while renewables are faster, cheaper, and more efficient
In sum, the nuclear industry seeks its own sales arrangements protected from competition, its own prices determined by political processes rather than markets, and diminished opportunities for its carbon-free competitors to express their value, reach their customers, and discover their own prices. This could be good for compliant legislators’ campaign contributions, but hardly in the national interest or helpful for climate protection.
If you haven’t heard this view before, it’s not because it wasn’t published in reputable venues over several decades, but rather because the nuclear industry, which holds the microphone, is eager that you not hear it. Many otherwise sensible analysts and journalists have not properly reported this issue. Few political leaders understand it either. But by the end of this article, I hope you will.
to protect the climate, we must save the most carbon at the least cost and in the least time, counting all three variables—carbon and cost and time. Costly options save less carbon per dollar than cheaper options. Slow options save less carbon per year than faster options. Thus even a low- or no-carbon option that is too costly or too slow will reduce and retard achievable climate protection.
anti-market monkeybusiness cannot indefinitely forestall the victory of cheaper competitors, but it can delay and diminish climate protection while transferring tens of billions of unearned dollars from taxpayers and customers to nuclear owners.
Does Nuclear Power Slow Or Speed Climate Change? Forbes Amory B. Lovins-18 Nov 19, Most U.S. nuclear power plants cost more to run than they earn. Globally, the World Nuclear Industry Status Report 2019 documents the nuclear enterprise’s slow-motion commercial collapse—dying of an incurable attack of market forces. Yet in America, strong views are held across the political spectrum on whether nuclear power is essential or merely helpful in
protecting the Earth’s climate—and both those views
are wrong.
China General Nuclear Power Group to invest $2.5 billion into a huge solar project – plus 2 GW of wind turbines
China’s nuclear operator to develop 1 GW solar field https://www.pv-magazine.com/2019/11/15/chinas-nuclear-operator-to-develop-1-gw-solar-field/
China General Nuclear Power Group is reportedly preparing to invest almost $2.5 billion into a huge solar project – plus 2 GW of wind turbines – in the autonomous province of Inner Mongolia. Local authorities say the massive project will be complete in 2021.
NOVEMBER 15, 2019 VINCENT SHAW Sources in Beijing have told pv magazine the state-owned China General Nuclear Power Group (CGN) is preparing to invest RMB17 billion ($2.43 billion) in renewables generation capacity in northern China, including 1 GW of solar panels.
The nuclear power company is also planning 2 GW of onshore wind capacity, with all the facilities to be built in the Inner Mongolian city of Ulanchabu.
The authorities in Ulanchabu say compliance reviews and administrative procedures will be carried out in the first half of next year with construction due to start on the massive renewables project by August, ready for completion in 2021.
Having been founded in 1994 in Guangdong province to operate China’s first nuclear power station – the Daya Bay plant – CGN has long since diversified into solar and wind power. The company claims to operate a 4.4 GW solar portfolio and 12.7 GW of wind facilities across all provinces of its homeland after funding more than 300 clean energy projects. The nuclear company also claims to have a 13.4 GW overseas renewable energy project pipeline.
The autonomous region of Inner Mongolia boasts excellent sunshine resources and the Inner Mongolia Solar Energy Industry Association said the construction of ultra-high voltage transmission lines in the province has enabled the authorities to set a curtailment target of near zero for solar electricity, and of 10% for wind power.
$2.7 Billion Renewables Project to revitalise Fukushima
Fukushima Starts $2.7 Billion Renewables Project https://www.bloomberg.com/news/articles/2019-11-10/fukushima-s-2-7-billion-project-takes-shape-nikkei-says By Isabel Reynolds November 10, 2019,
- 600 megawatt wind and solar project to supply Tokyo area
- Development Bank of Japan, Mizuho to provide part of funding
Work is set to begin on a $2.7 billion renewable energy project in Japan’s Fukushima, the site of one of the world’s worst nuclear disasters, the Nikkei newspaper said Sunday.
The plan is for the wind and solar project to generate and transmit up to 600 megawatts of power, which will be supplied to Tokyo and the surrounding area, according to the paper.
Development Bank of Japan and Mizuho Bank are among the institutions planning to provide the 300 billion yen in funds needed for the project by 2023, the paper said.
The project forms the main pillar of a government plan to help revive the region’s economy by generating energy in mountainous areas and on farmland that became unusable after the 2011 disaster, the Nikkei said.
11 solar power plants and 10 wind power plants for Fukushima prefecture
Twenty-one plants and new power grid to supply Tokyo metropolitan area SHIKO UEDA and SUGURU KURIMOTO, Nikkei staff writersNOVEMBER 10, 2019 TOKYO –– Japan’s northeastern prefecture of Fukushima, devastated during the 2011 earthquake and nuclear disaster, is looking to transform itself into a renewable energy hub, Nikkei has learned.
A plan is under way to develop 11 solar power plants and 10 wind power plants in the prefecture, on farmlands that cannot be cultivated anymore and mountainous areas from where population outflows continue.
The total cost is expected to be in the ballpark of 300 billion yen, or $2.75 billion, until the fiscal year ending in March 2024.
The government-owned Development Bank of Japan and private lender Mizuho Bank are among a group of financiers that have prepared a line of credit to support part of the construction cost.
The power generation available is estimated to be about 600 megawatts, or equivalent to two-thirds of a nuclear power plant. The produced electricity will be sent to the Tokyo metropolitan area.
The plan also envisions the construction of an 80-km wide grid within Fukushima to connect the generated power with the power transmission network of Tokyo Electric Power Co. That part of the project is expected to cost 29 billion yen.
In Tamil Nadu, Rooftop Solar Has the Potential to Outdo Nuclear Power
In Tamil Nadu, Rooftop Solar Has the Potential to Outdo Nuclear Power https://thewire.in/energy/tamil-nadu-rooftop-solar-nuclear-power Poonkuzhali 8 Nov 19,
Tamil Nadu has said its vision is to have an installed solar powergeneration capacity of 9,000 MW by 2023.
In September, India and Russia announced joint plans to set up 20 nuclear power units in the former over the next two decades.
India’s nuclear establishment believes that the use of nuclear energy can only be good for the country’s industrial development and prosperity. However, nuclear isn’t the only mode of power generation that can make such a claim.
Tamil Nadu is the only state in the country with two nuclear power plants: at Kalpakkam and Kudankulam.
The Kalpakkam complex, commissioned by 1986, has four operating units. Two of them are of 235 MW capacity and two of 600 MW capacity. The complex’s gross generation in 2017-2018 was 1,194 MU (at 64% availability; in 2015-2016, with an availability of 97%, it generated 1,861 MU).
The Kudankulam power plant is the single largest nuclear power station in India. It has two operational units of 932 MW (net) each. In 2018-2019, with an availability of 33%, it generated 2,797 MU.
Tamil Nadu isn’t the sole beneficiary of the power generated by these plants. In 2016, it required 100,319 MU. It received 99,691 MU from various sources, including state, central and private, and renewable and non-renewable. Of this, nuclear power plants supplied 4,999 MU.
As it turns out, it’s possible to generate this 4,999 MU from rooftop solar panels alone.
On March 31, 2017, Tamil Nadu had the highest installed capacity of grid-connected renewable power (10,562.39 MW), followed by a distant Maharashtra (7,647.60 MW), thanks to wind energy.
According to a 2014 book by S. Gandhi, former president of the Electrical Engineers’ Association of the Tamil Nadu Electricity Board, a 1-MW panel in Tamil Nadu produces 1.5 MU per year on average. This conversion accounts for various factors, including that power production happens only during the day and that production efficiency varies according to the season. Extrapolating from the book, to produce 4,999 MU, Tamil Nadu needs an installed capacity of 3,333 MW.
A 1-kW solar panel over 1,000 roofs can produce 1 MW, so to produce 3,333 MW, we need to install 1-kW solar panels over 3,333,000 roofs. A 1-kW rooftop panel requires about 100 sq. ft. According to state data, there are 2,392,457 buildings in town panchayats alone. Including the total area of all rooftops in Tamil Nadu’s urban centres, and assuming all roofs will generate 10 W/sq. ft., solar power should be easily able to provide the requisite 3,333 MW.
The Government of India and various state governments have consistently presented nuclear power as a safe, sustainable and preferable alternative to coal power. However, while nuclear power plants have very low carbon emissions and have historically caused the fewest fatalities, these advantages are substantially offset by the cost of disposing radioactive waste and an opaque administrative setup in India that has often disprivileged marginalised communities living around power generation complexes.
On the other hand, the biggest downsides of solar power generation are that solar panels lower the productivity of the land they’re setup on, and the batteries used to store power contain toxic materials whose extraction and processing has harmed people in other, often poorer, countries.
But both issues are quickly resolved in the current example. The question of land productivity doesn’t apply since the panels are to be installed on rooftops. Second, in its solar energy policy published in February 2019, the Tamil Nadu government declared it now has the technology to support grid-connected solar panels on a large scale. This means even domestic solar panels can be connected to the grid, obviating the need for power storage batteries.
According to its policy, the state government says its vision is to have an installed solar power generation capacity of 9,000 MW by 2023.
As of today, the Tamil Nadu government requires every new building erected in the state to be equipped with a rainwater harvesting system. If lawmakers issue a similar mandate vis-à-vis solar panels, at least for apartment complexes and non-residential buildings, Tamil Nadu could soon be self-sufficient about its energy needs, if not produce a surplus it can sell to its neighbours.

Nuclear costs escalate as wind prices keeps falling,
WindEconomics: Nuclear escalates as wind prices keeps falling, WindPower monthly, 31 October 2019 by David Milborrow
Nuclear power is too expensive. That is the implicit conclusion of the UK government, which has issued a consultation document on possible ways of reducing the electricity price.
This would be possible if the government — which can borrow money cheaply –shouldered some of the risks and/or provided some finance.
The consultation focuses on “regulated asset base” models. The document describes these models as “typically used for funding UK monopoly infrastructure” and involving “an economic regulator who grants a licence to a company to charge a regulated price to users of the infrastructure”.
One of the advantages for developers is that charges can be levied before the project is completed.
The range of possible prices quoted in the consultation document, shown in the top below, bears out the maxim that “prices are what you want them to be”.
They range from a minimum of -£6/MWh, when the state shoulders all the risks and the rate of return for the government is 2%, to £137/MWh, when the investors demand a 12% rate of return and bear all the risks. In the first case, the cost to the taxpayer would be £18 billion.
The present contract for the under-construction Hinkley Point C power station, which has been widely criticised, is based on a 9% rate of return and an electricity price of £92.5/MWh (2012 prices). That is about £106/MWh (€119/MWh on 1 October) in 2019 prices.
It was announced on 25 September that the estimated cost of the project had risen by nearly 10% — to £21.5-22.5 billion.
The price of electricity to the consumer will not increase, but the profitability for developer EDF will be reduced. This gives a new benchmark price for nuclear of £6,750/kW, as the facility’s output will be 3.26GW.
The effects of moving away from state funding can be illustrated by looking back to the first public inquiry for Hinkley Point….. https://www.windpowermonthly.com/article/1663433/windeconomics-nuclear-escalates-wind-prices-keeps-falling
