China’s plans for some 100 new coal-fired power vegetation to again up wind and photo voltaic capability have sparked warnings that the world’s second-biggest economic system is probably going to find yourself lumbered with much more loss-making power belongings.
Analysts query the logic of insurance policies that intend to scale back the function of the dirtiest fossil gas however on the identical time require extra coal-fired power vegetation to be constructed – particularly on condition that solely a small quantity of older vegetation are usually retired annually.
The plans additionally spotlight how native authorities pursuits have impeded the event of an efficient nationwide power market that may permit surplus power to be delivered to areas that want it, they add.
“The reality is that China has more coal power capacity than it needs,” stated Zhang (*106*), director at Draworld Energy Research Centre. “It doesn’t make sense to give more incentives for more coal-fired power investments.”
China is the world’s largest and fastest-growing producer of renewable power, which is predicted to account for a 3rd of all power provided to its grid by 2025, up from 28.8% in 2020.
But it was scarred by a report drought final yr that slashed hydropower output, forcing factories all through the southwest to shut down and elevating considerations that power shortages may undermine its post-COVID financial restoration. The expertise elevated its willpower not to be too reliant on the intermittent nature of wind and photo voltaic power and has made China the one main economic system constructing new coal-powered vegetation.
The building of 106 gigawatts of coal-fired power was authorized final yr – 4 instances greater than in 2021 and the very best quantity since 2015, in accordance to analysis printed final month by the Centre for Research on Energy and Clean Air (CREA) and Global Energy Monitor (GEM).
That’s equal to a couple of hundred massive coal-fired vegetation and sufficient to provide the entire of Britain. At least 50 GW of that capability started building in 2022, the report stated.
China’s National Development and Reform Commission (NDRC) has additionally flagged that a minimum of 200 GW of coal capability is predicted to be deployed to help renewable power.
China’s massive soar in coal power approvals has sparked fears that there might be backsliding on its climate goals.
The CREA-GEM report says it will not essentially imply the sector’s coal use or carbon emissions will climb. But for China to make good on its goals – specifically a peak in emissions earlier than 2030 and turning into carbon impartial by 2060 – the loss-making sector’s plant utilisation charges will most likely have to slide additional.
The NDRC’s National Energy Administration didn’t reply to a request for remark.
Loss-making, under-utilised
Coal accounted for 58.4% of China’s complete power technology final yr, however excessive costs have meant many vegetation have suffered losses for years. More than half of the nation’s massive coal power companies have been loss-making within the first half of 2022, in accordance to the China Electricity Council.
And regardless that many vegetation have been producing extra final yr to compensate for the decline in hydropower output, the common utilisation fee inched down to 52.4%.
Analysts word present coal vegetation may present adequate backup for renewables in the event that they have been plugged right into a nationwide market, however China’s power sector stays fragmented.
Historically, power vegetation have been constructed to help native trade and native GDP development fairly than nationwide power provides, with provinces reluctant to depend on different provinces for his or her wants.

Power vegetation are additionally not motivated to maximise power output as a result of costs are fastened for residential customers whereas value hikes for enterprise customers are restricted to 20% of the fastened tariff.
The NDRC has been engaged on capability fee mechanisms that compensate coal power vegetation for the decline in earnings as they alter to their new function as backup suppliers.
The drought-prone southwestern province of Yunnan, which will depend on hydropower for many of its electrical energy, lately arrange a capability market during which coal vegetation are paid to be out there to fulfil provide shortfalls. Other areas are additionally concerned in pilot schemes.
“I think the expectation of these capacity payments is one motivation for coal power groups to pursue new projects despite the fact that power generation from coal is unprofitable at the moment,” stated Lauri Myllyvirta, lead analyst at CREA.
It can be unclear who might be paying for the subsidies, stated Zhang at Draworld Energy, including it might be “terrible news” if the prices have been to be shouldered by renewable power turbines.
Yunnan’s provincial planning company didn’t reply to a request for remark.
Instead of constructing costly new vegetation, China may as an alternative encourage present vegetation with surplus capability to ship electrical energy to areas that want it essentially the most, stated Matt Gray, chief government of suppose tank TransitionZero.
“It would be far cheaper… to incentivise provincial trading than incentivising new loss-making coal,” he stated.
