Abstract

The current Chinese electricity market and carbon market are built relatively independently, without coupling and synergy, and the incoherence between the two markets is beginning to emerge. Carbon emissions costs in the carbon trading market will affect the marginal cost of renewable energy and thermal power in the electricity market, limiting market participants’ profitability. In order to simulate and evaluate the changes of LCOE of renewable energy and thermal power in the “electricity-carbon” market environment, this paper presents the calculation method of carbon emission cost of thermal power and CCER benefit of renewable energy based on the relevant regulations in China, and calculates the carbon emission cost transmission rate of thermal power based on Cournot model. In addition, we proposed a method for calculating the LCOE based on the international common calculation method for LCOE, combined with China’s taxation policy and the cost and benefit factors of renewable energy and thermal power in the carbon market, and proposed a method for calculating the LCOE applicable to the “electricity-carbon” market environment in China. The findings indicate that as a result of the influence of the carbon market, the levelized cost of energy (LCOE) cost of thermal power will increase, and the profitability of thermal power in the electricity market will be further reduced. On the other hand, the LCOE cost of renewable energy will further decrease, and its profitability will improve due to the additional CCER benefits in the carbon market.
“电-碳”市场环境下基于碳成本传导的LCOE计算方法
目前的中国电力市场和碳市场是相对独立构建的,没有耦合和协同,两个市场之间的不连贯性开始显现。碳交易市场中的碳排放成本将影响电力市场中可再生能源和火电的边际成本,限制市场参与者的盈利能力。为了模拟和评估“电碳”市场环境下可再生能源和火电的LCOE变化,本文根据中国的相关规定,提出了火电碳排放成本和可再生能源CCER效益的计算方法,并基于库诺模型计算了火电的碳排放成本传导率。此外,我们在国际通用LCOE计算方法的基础上,结合中国的税收政策以及可再生能源和火电在碳市场中的成本效益因素,提出了一种适用于中国“电碳”市场环境的LCOE的计算方法。研究结果表明,由于碳市场的影响,火电的平准化能源成本(LCOE)将增加,火电在电力市场的盈利能力将进一步降低。另一方面,可再生能源的LCOE成本将进一步降低,其盈利能力将因碳市场中CCER的额外收益而提高。
