The main primary source of electricity in China is coal (more than 78%). The remaining part in 2008 was shared between hydropower (about 17%) and nuclear power (about 2%), see Figure 7.6.

In the case of China the costs of generating electricity at coal-fired and gas-fired power plants are so low (without carbon pricing) that neither SMRs nor state-of-the-art large reactors can currently compete (neither at a 5% nor at a 10% discount rate). However, nuclear power plants are currently being intensively built in China, showing that the economic factors are not the only ones in decision making.

In the Chinese case, small reactors could be competitive only with renewable plants (onshore wind, solar).
