Abstract: The Chinese government will implement renewable portfolio standards (RPS) and emissions trading (ET) in the power industry. The retailer will be required to comply with the quota obligation. This paper constructs the two-echelon supply chain to study interactions between RPS and ET and their policy effects. The results indicate the following conclusions. When RPS has operated, introducing ET causes in an increase in the wholesale price of thermal power and the retail electricity price, whereas the wholesale price of electricity from the renewable energy source (RES-E) decreases. Thus, the introduction of ET is beneficial for realizing a level competition field between two types of power. However, ET also gives rise to an increase in the retail price, which dampens the consumer’s demand for power, which can be strengthened by the rising carbon permit price and carbon abatement cost. On the other side, when the quota obligation and the difference between retailers increase, the cost that the retailer passes on the retailer will decrease. As a result, the decreasing range of renewable power prices and growing retail prices drop, but the internalization of the environment is not affected. Besides, a higher quota obligation and a larger difference between retailers also attenuate the fluctuation of the power price and the demand for the power caused by the rise of carbon permit price and the cost of carbon abatement.
