Coal plants decline continues inexorably worldwide

Ecofin Agency March 22, 2017

Coal power plant projects experienced a sharp decline in 2016, mainly in India and China, mainly, according to the report "Boom and Bust 2017: Tracking The Global Coal Plant Pipeline", published by CoalSwarm, Greenpeace and Sierra Club.

According to the study, the volume of projects at the pre-construction stage (announced and having obtained building permits) decreased by 48% during 2016, while that of the plants whose construction started during the Last 12 months has dropped 62%. The volume of coal-fired power plants, completed, fell by 29% and the number of new permits issued saw their number decrease by 85%. In total, more than 100 coal-fired power plant construction projects, representing a capacity of 68 GW, have now been stopped in these two countries..

"The record number of frozen projects shows that the Chinese central authorities and Indian bankers have understood that building so many coal-fired plants would be a huge waste. Whatever its suddenness, the transition from fossil fuels to clean energy in the electricity sector is a positive trend for our health, climate security and job creation. Clearly, this trend is on track to last. ”Said Ted Nace, director of CoalSwarm.

In general, China has frozen 67% of its current coal-fired power plant projects, India 74% and 67% of the current power plants around the world have been frozen. Records were also broken in 2015 and 2016, with regard to the shutdown of plants already in operation. In Europe and the United States, 64 GW of coal-fired power plants have been shut down. Beijing, the Chinese capital has closed its last coal-fired power plant. The United States has shut down 2010 of its coal-fired power plants since 251, and the 52% drop in coal consumption in the United Kingdom has made it possible to reach the lowest carbon emission level since 1894.

"Whatever some may say, the reign of coal is over," said Michael Bloomberg, former mayor of New York City, referring to the promise of the new US government to increase the number of jobs in the coal industry.

China wants to create coal giants

Posted on 05/01/2018 Reuters BEIJING News

China announced on Friday its intention to create very large coal companies by the end of 2020, the world's largest coal producer seeking to rationalize its sector and close the unprofitable mines.

The National Development and Reform Commission (NDRC) announced in a statement that by the end of 2020, China plans to create a number of giant mining companies, each with a production capacity of 100 million tonnes per year. coal, competitive on the world market, which will contribute to the modernization of the sector.

In June, China had more than 4.000 coal mines with a total capacity of 3,41 billion tonnes per year, the National Energy Agency (NEA) announced in November. In 2016, China produced 3,64 billion tonnes of coal.

Only six mines are capable of producing more than 100 million tonnes per year to date, according to the national association of coal producers, including Shenhua Group, China Coal Energy and Datong Coal Mine.

The project follows last year's takeover of the state-owned electric company China Guodian Group by the country's largest coal producer Shenhua Group to create the world's largest power distribution group.

In addition to its desire to modernize its unprofitable and highly indebted public enterprises, China is engaged in a fight against pollution which supposes a decline in the place of coal which still produces most of the country's electricity.

As part of its five-year plan until 2020, China has pledged to phase out around 800 million tonnes of unprofitable capacity. Coal production will reach around 3,9 billion tonnes per year by 2020.

Coal plant construction slows worldwide

By Loïc Chauveau the 23.03.2018

A report by three American NGOs reveals a marked slowdown in coal plant projects around the world. However, there are still too many constructions in progress to reach the objective of limiting temperatures to 1,5 ° C.

The Coalswarm group of researchers, the American conservation association Sierra Club and the NGO Greenpeace assure it: the decline of
coal as a source of electricity is underway. According to the calculations of the three organizations, over the past two years the number of new plants entering service has fallen by 41% while the start-ups of construction sites have fallen by 73%. Permits and planned projects fell by 59%. At the same time, between 2015 and 2017, 97 GigaWatts (GW) of capacity was shut down. These power plant shutdowns mainly took place in the United States (45GW), where the policy adopted is favorable to coal. China scrapped for 16GW and the UK (which is in the process of giving up this type of energy) 8GW. We are therefore witnessing a "scissor effect". The authors of the report have in fact calculated that in 2022, the closures of coal-fired power plants will be more numerous than the openings. The share of this energy will then begin to decline sharply in the global energy mix.

This disaffection has several causes. In the United States, the closures are linked to the growing production of shale gas, which is more profitable than coal. Despite the efforts of the current President of the United States, Donald Trump, these economic rules condemn the country's mines. In addition, until now, closings have taken place in developed countries. They were mainly power stations at the end of their activity. Thus, 290 GW of capacities have reached the 39 years of lifespan planned for such units. 144 GW are located in the United States and 59 GW in the European Union. An additional 315 GW will reach the age limit at the end of 2030.

Developing countries begin to turn away from coal

The novelty is that this decade has been marked by the abandonment of coal in developing countries. In East Asia (China, Japan, Korea), while 553 GW are under construction, 758 GW of projects have been abandoned, representing a abandonment rate of 59%. In India, where the urgency is for the electrification of the whole country, only 17 plants are under construction, and this, say the authors, due to the disaffection of private investors. As in the United States, gas is the main competitor of coal. But the cost, which has become very competitive of renewable energies, is also a game-changer. The fact that solar and wind are now cheaper than fossil fuels is a phenomenon that dates back only to the middle of the decade and the effects are beginning to be felt on the choices of investors.

This decline is certainly good news for the climate and the achievement of the Paris agreement to keep the rise in global temperatures below 2 ° C and if possible at 1,5 ° C (this rise is now of 1,1 ° C). However, the recorded decline is not sufficient. “The total CO2 emissions from coal-fired power plants around the world are 233 gigatonnes, higher than the total budget for 1,5 ° C and 2 ° C,” say the report's authors. To meet the 1,5 ° C threshold, all current construction projects would have to be canceled and most plants closed before their 40 years of age. And even the 2 ° C target implies an accelerated closure of active power plants. This is the grim warning of the report.

While we gargle with more and more virtuous projects ( :D ) in terms of carbon emissions, Greece plans to build two new lignite power plants (worse than coal).

I suppose that the decisions were taken well before and result, in part, from the situation in Greece and the tremendous opportunity * that this field represents.
You surely noticed that it is a German bank, our neighbors so green : Wink: , which largely finance this project!

* Great only from a very limited point of view, obviously: the ability to quickly produce cheap electricity ...

with the Mediterranean sun, they must have had a hot blow on the head ...

finally, if they are "backup" power plants, that can be justified, if it is for base electricity, no.

Bof, reassure us.

The production of these two plants will remain lower than the only increase in the production of German lignite + coal plants for this first half of 2018 alone ...

We advance, we advance ... They will always be able to convert to saffron culture and tourism (dixit wwf); it is true that their devastated landscapes are so beautiful ...

NB Coal or lignite thermal power stations are completely incapable of making backups, it is too expensive to stop and restart; so much so that the Germans prefer to sell their electricity at a negative price rather than shutting down their power plants (the majority in this country) ...

PS There are still days when we seriously ask ourselves the question of gunsling ourselves rather than reading things like this: a country claiming to be the champion of ecological transition, which has just pressed for several years - to death - a another much weaker country, which allows itself to come and invest there for such bullshit. At times, I am ashamed of humanity ...
