Singapore — More than 800 coal-fired power plants in emerging countries could be decommissioned and profitably replaced by cleaner solar energy starting from the end of the decade, research shows.
Though only a tenth of existing coal plants were scheduled to shut down by 2030, more could close if efforts were made to identify opportunities, the Institute for Energy Economics and Financial Analysis (IEEFA) said.
“The key problem here is a lack of a pipeline of well-defined, contracted, bankable coal-to-clean transactions,” Paul Jacobson, lead author of the report, said.
About 15.5-billion tonnes of carbon dioxide are generated every year by 2,000GW of coal power. The International Energy Agency says emissions need to reach zero by 2040 if temperature rises are to remain within the threshold of 1.5°C.
Costly
But decommissioning is costly, especially if plants are still paying off debt or tied to power purchase agreements that commit them to supplying electricity over decades.
Governments have been looking for solutions to pay for the transition — including the Asian Development Bank’s energy transition mechanism — but only a small number of projects have gone ahead.
The 800 viable transition targets identified by IEEFA include about 600 built 30 years or more ago, many of which have repaid debts and are no longer tied down by lengthy power purchase agreements.
With profit margins for renewables now sufficient to cover the cost of replacing coal plants, decommissioning the remaining 200 plants built 15-30 years ago could also be affordable, though obstacles remain, including fossil fuel subsidies that inflate an asset’s value.
Decommissioning newer plants will be a bigger financial challenge, particularly in countries still building fresh capacity, including Vietnam.
Environmental groups have criticised transition financing for paying polluters not to pollute. Jacobson said “guardrails” were required to avoid creating perverse incentives.
“Companies that continue to build new coal power plants while seeking concessions to build renewable energy should not be allowed to use that to benefit from this,” he said.
