Can repositioning coal power accelerate the net-zero transition?
A study on China finds that repositioning coal power from a baseload resource to a flexibility provider can accelerate the net-zero transition by mitigating stranded assets, enabling greater integration of renewables, and reducing transition costs.
Why is repositioning coal power important?
In terms of power generation and storage technology investments, repositioning coal power in the short- to medium-term transition periods significantly supports the growth of renewable energy, leading to an increase in capacity investment.
How does flexible dispatch of coal power accelerate the net-zero transition?
Flexible dispatch of coal power accelerates the net-zero transition of the power system in four ways. First, it increases the system value of coal power, thereby boosting the cost competitiveness of CCS retrofitting.
Could unabated coal power be an alternative flexibility resource?
Coal power exhibits the ability to dispatch flexibly to respond to the fluctuating demand and VRE loads 48, 49, 50. Promoting unabated coal power in the short term as an alternative flexibility resource in coal-rich, gas-poor countries like China, could be economically effective.
How can a flexible dispatch of coal power improve system value?
By enhancing the flexible dispatch of coal power and reducing utilization hours, the system value of coal power can be significantly increased. This approach helps mitigate early retirement of existing coal power capacity and reduces transition risks.
