Renewables set to phase out coal by 2030

A new global analysis of 6,685 coal plants finds that it is now cheaper to build new renewable generation than to run 35% of coal plants worldwide. By 2030, that percentage will increase dramatically, with renewables beating out 96% of today’s existing and planned coal-fired generation.

The 4& exception is in markets with extremely low fuel costs, where coal is cheap and plentiful, or with uncertain policies for renewables, like Russia.

The study, conducted by pro-climate-action financial think tank Carbon Tracker, covers about 95% of worldwide operating capacity and about 90% of under-construction capacity, Green Tech Media reports.

The report’s authors lay out three inflection points for the transition away from coal-fired power. They forecast the first for 2025, when renewables economically beat out new-build coal. According to the report, countries including Australia, China and India are already there.

But the second inflection point, when new renewables and gas beat existing coal, will mean an existential crisis for the coal industry, according to the authors.

This year the Netherlands announced a coal ban. Countries including China, Hungary and Germany have also made moves to ditch coal, whether by reducing consumption or considering and instituting full-blown bans. And a November report from the Institute for Energy Economics and Financial Analysis forecasted that 2018 will bring a record number of US coal retirements totaling 15.4 gigawatts (an S&P analysis from later in the month reported that 2018 will narrowly miss the record, retiring 14.3 gigawatts compared to the previous 2015 record of 14.7 gigawatts).

Though some of those global initiatives were designed to reduce pollution or combat climate change, Matthew Gray, Carbon Tracker’s head of power and utilities and the report’s co-author, said the pressures on coal largely defy policy. At this point, its decline is economic. Cheap natural gas and the falling costs of renewables have overtaken coal’s edge.

“Trends that we’re seeing, regardless of climate policy, could potentially get us to a phaseout that is consistent with the Paris Agreement, simply because over time, these coal-fired power plants will just become more and more unviable,” said Gray.

“The incentive to shut them down and build lower-cost [plants] will become greater and greater.”

According to Carbon Tracker, in China it will be more expensive to operate coal than to build new renewables by 2021. The European Union hits that point earlier, in 2019. In the US, it has already arrived.

At the same time, there’s significant political pressure to extend the lifetime of coal generation. FirstEnergy president and CEO Charles Jones said this month the country is heading into a difficult place by allowing perfectly good coal and nuclear plants to retire early. The Trump administration’s interest in supporting coal and nuclear plants is now well-documented.

There’s also a lot of coal left to retire. China has more than 1 million megawatts of capacity operating or under construction, while the EU has 155,301 megawatts. The US is looking at 261,972 megawatts.

Ultimately, the report’s authors write that the orderliness of the transition away from coal power rests on policymakers’ and investors’ willingness to prepare.

They suggest the economic consequences for those caught behind are profound. The report forecasts that transitioning away from coal, in a scenario where policies keep global warming below 2°C, could mean avoiding US$267 billion in stranded assets. In a previous Carbon Tracker report, the organization found that consumers could save US$10 billion annually by 2021 if new-build gas generation and renewables replaced coal-fired power.

The report notes that which party or segment shoulders the economic burden of continued reliance on coal depends on market structure. In liberalised markets, utility and public company shareholders will be most exposed to risk. In regulated markets, the onus will filter through the state down to taxpayers and energy consumers.

Policymakers and politicians who continue pushing coal, according to the report, will have to choose whether to subsidise more expensive power or make customers pay for it. But the report is clear that the transition “increasingly seems inevitable,” even in the US’ coal-friendly policy environment.

“What we are seeing on the ground is that coal-fired power under the Trump administration is not increasing,” said Gray.

“What we’ve found since he came into power is, he doesn’t actually have that much influence on power regulation.”

In fact, coal retirements have continued piling up under Trump. S&P’s recently published investigation shows that this year the pace of coal retirements doubled. The story included comments from numerous utilities that don’t expect to add new coal generation to their portfolios.

Though Gray said the US is the most blatant example of policymakers pushing coal over other technologies, it’s far from the only market where this is happening.

“We do think that coal is being supported unnecessarily,” he said.

“Certainly, supporting new-build coal anywhere in the major markets where solar is developed makes little to no sense.”
