Guest post: ‘Peak coal’ is getting closer, latest figures show

thomas harrisson

Dr Christine Shearer is a researcher and analyst for the US-based energy research group CoalSwarm.Total global coal capacity continues to inch up, but a peak is on the horizon. In the first half of 2018, retired capacity has nearly matched newly operating plants and the global pipeline for proposed coal is quickly eroding.This is according to CoalSwarm’s latest Global Coal Plant Tracker results, which we completed in July 2018. Our figures confirm the sector is in the midst of rapid change. [Carbon Brief recently used the data from the tracker to produce a global coal plant map and timeline.]Even if global coal capacity peaks soon, however, the sector is set to breach its share of internationally agreed climate goals — unless large numbers of coal plants retire early.

The most dramatic changes are taking place in China and India, which are both dealing with a growing number of coal plants operating well or are . In China, this is primarily due to . In India, it is due to and increasing competition from renewable power.The table below shows that while some countries have a significant amount of planned or under-construction coal capacity, the amount under development does not nearly match the scale of development in China and India, particularly over the past decade. Many of the plans in these other countries are highly reliant on foreign aid, as discussed below.To date, have committed to phase out coal use, although none of the countries include the 10 shown above that are home to 85% of the world’s existing coal plants. However, Germany is a coal phase out, and past and planned retirements put the US on track to close a of coal plant capacity this year.

§ Coal pipeline shrinks again

The amount of coal power capacity in pre-construction stages has declined every year since 2015. So far, 2018 has been no exception, with proposed capacity dropping 20% in the first half of 2018 (January to June), from 447 gigawatts (GW) at the end of 2017 to 364GW by July 1, 2018, a decline of 83GW. Overall, the pre-construction pipeline has fallen two-thirds since 2015, when it was 1,090GW. Planned coal power capacity in pre-construction status has declined from 1,090GW in 2015 to 364GW in July 2018, with the biggest drops in China (light blue) and India (dark blue). Source: , July 2018. Planned new coal capacity has been cancelled around the world, with particularly rapid falls in China and India. At the end of 2015, China had plans to build 515GW of new coal capacity. That figure now stands at 76GW. In India, the pre-construction pipeline has shrunk from 218GW in 2015 to 63GW today.Most notably, our figures show that less than 2GW of new coal capacity has been proposed in either China or India in 2018 – a significant development for the two countries that have been the site of of the world’s new coal power capacity since 2006.While some analysts the drop in China and India might be replaced with an increase throughout other parts of the world, the pipeline across the rest of the world also continues to decline. Notably, Japan has 3.6GW of proposed coal capacity since 2017, while South Korea will issuing permits for new coal plants.

§ More construction in China

Although the pre-construction pipeline for new coal has declined, coal power capacity under construction increased 27GW in the first half of 2018, from 209GW at the end of 2017 to 236GW by July 2018, shown in the chart below.This increase is due to China (light blue), which is moving forward with a number of coal plants that were thought to be postponed, if not cancelled. Still, global capacity under construction has fallen nearly a third since 2015, when 339GW was being built. Coal power capacity under construction declined from 339GW in 2015 to 209GW in 2017, but went up to 326GW in July 2018, as China (light blue) began or continued construction on coal plants thought to be postponed by the central government. Source: , July 2018. China continues to deal with a backlog of about 260GW of coal power capacity authorised for construction from late 2014 to 2016, according to regional government data. During this time permitting authority was transferred from the central government to the provinces, who have used coal plants as a source of quick economic growth.To rein in growing overcapacity, China’s central government in 2016 to slow the pace of new coal plants being built. These proposals covered 430GW under various stages of development — comparable to the entire fleets of the US and India combined.About 54GW of that capacity has since moved into construction, according to the CoalSwarm database, although it before connecting to the grid, reportedly to ensure compliance with central government provisions.The three other countries that began construction on new coal capacity in 2018 were Indonesia (0.9GW), Japan (1.4GW) and Taiwan (0.8GW).

§ Peak coal capacity near

From January through to June 2018, nearly 20GW of new coal capacity was commissioned: 12GW in China (blue area in the chart, below) , 5GW in India (red), and 3GW in the rest of the world (South Africa, Pakistan, Vietnam, Philippines and Japan).Top: Coal power capacity additions and retirements (gigawatts) between 2000 and July 2018 (coloured columns) and the global net change (black line). Bottom: The number of coal units added and retired by country (coloured columns) and the global net change (black line). Source: , July 2018.While significant, the amount of coal power capacity that began operating during the first half of 2018 (20GW) was nearly matched by the amount retired (16GW), for a net increase of just 4GW – the slowest rate of growth on record. If the slowdown continues global coal capacity should peak , if not sooner.About 12GW of the retired capacity was in the US, with another 6GW planned to close by end-2018. This would make 2018 the second-highest year for US coal retirements after 2015, which had 21GW of retirements. In the EU, retirements in the first half of 2018 were less than 1GW, well below the region’s annual average of 5GW over the past decade. However, more than half of its current member countries have committed to phase out coal by 2030.Nearly 3GW of coal capacity was retired in China and India in the first half of 2018. India has 48GW of coal plant retirements through to 2027, mainly end of life, subcritical coal plants and those ill-equipped to meet . China has to close small coal plants under 300MW, which make up about 20% of its current 957GW of coal power capacity, although they can be replaced by new “ultra-low-emission” coal-fired units.In June, Carbon Brief noted the number of coal units in the world , as countries including China phase out older, smaller units. In the first six months of 2018 that peak was passed, with 43 units added and 52 retired, meaning the global coal fleet shrank by nine units.

§ Coal and climate change

Coal is the biggest global contributor to heat-trapping CO2, making it essential to phase out its emissions to meet .The most cost-effective route to meeting the Paris Agreement’s “well below” 2C limit would see richer OECD and EU nations ending unabated coal use by 2030, China by 2040, and the rest of the world by 2050, to climate science NGO . (The IEA’s “well-below 2C” scenario sees unabated coal use worldwide.)However, just the currently operating coal capacity of these regions already exceeds those targets, even without new development. The figure below shows total coal capacity through to 2060 if all operating coal plants retire as currently scheduled, or at 40 years of age — the current average retirement age — with plants that are already older than 40 years closing by 2030.Currently operating coal power capacity in the OECD/EU (blue), China (red), and the rest of the world (green) retired at 40 years of age will exceed Paris agreement coal phase-out dates (shaded areas).The shaded areas show coal power capacity operating in each region beyond the phase-out deadlines suggested by Climate Analytics. This excess amounts to 198GW in OECD/EU nations, 844GW in China and 199GW in the rest of the world.If this excess capacity is not retired early — implying potential stranded asset losses for plant operators — then other sectors of the economy would have to cut CO2 even faster, or the Paris temperature limit would likely be breached.

§ Proposed funding highly concentrated

offerrestrictedcommittedIndonesiaPakistanBangladeshVietnamRussiaEgyptBosniaSerbiaTurkey
In the latest CoalSwarm update, we estimate that Chinese, Japanese, or South Korean governmental and private institutions are funding, or have proposed to fund, more than two-fifths (41%) of all capacity under development outside China and India. Chinese organisations alone account for nearly 30% of the total.This does not mean that all the projects will be funded by banks or organisations in these three countries, but it does show the growing role they play in global coal plant development. Chinese, Japanese, and Korean construction companies and power equipment manufacturers often compete for contracts and, as part of the bidding, may funding assistance. Host countries are often looking for funding as the World Bank severely coal financing in 2013, and an increasing number of major international banks and insurance firms have to end coal financing.Increasingly, the coal plant industry appears to be moving from a predominantly national model of development and domestic coal supply — as pursued by the US, Australia and much of Europe, followed by China and India — to a more trans-national model under which construction, funding and coal supply or mining are often outsourced.This model dominates many of the countries with the most coal plants under development outside China and India, including , , and . Chinese financing is also behind recent large coal plant proposals in and , and is also playing a growing role in , and , often reviving plants that appeared to be shelved for lack of funds.

Article information

The Global Coal Plant Tracker is an online database developed by CoalSwarm that maps and describes every operating coal-fired generating unit and every new unit proposed since 1 January, 2010 (30MW and larger). Collaborators include Greenpeace, Sierra Club, CAN Europe, GreenID and Kiko Network.

Both China and India are now struggling with excess coal power capacity that is competing with and for lower-carbon alternatives. This means a growing number of coal plants are operating well below their designed utilisation rates, leading to less income than expected for operators. These excess coal plants risk becoming , unable to earn an economic return on investment.The Indian government estimates 40GW of the country’s coal plants are , including 25GW that have been completed without any power purchase commitments. This number may grow, as financial thinktank nearly 30% of the country’s operating coal plants are more expensive to run than the lowest 2017 bids for solar power.State power company NTPC in July 2018 low renewable costs when it plans for new coal. Overall, of proposed coal power capacity has been shelved or cancelled in India since 2010 – over three times its operating capacity of 219 GW.China is also dealing with excess coal plant capacity. From 2006 to mid-2018 China commissioned 70% (715GW) of the world’s new coal-fired capacity. That rapid expansion — coupled with the 2014–2016 spurt in provincial coal permitting — is now rubbing up against the country’s ambitious renewable goals. The average utilisation rate for thermal plants in 2015, where it has stayed, meaning Chinese power company profits from coal power are .In response to the overcapacity problem, China’s caps total coal capacity at 1,100GW in 2020. Yet, even with the cap, the country is facing over of excess coal capacity, according to some estimates, with further coal plants representing potentially billions of dollars of wasted capital. The country needs to strengthen its coal plant restrictions and increase retirements to prevent further excess coal-fired capacity.
