China generates a lot of electricity but from what I understand prices aren't that much different to in the USA because of grid constraints.
China's electricity pricing involves cross-subsidies. Residential and agricultural users pay the lowest rates, which are generally below the cost of supply. Commercial and industrial users pay more and contribute the most of grid revenue.
Prices vary by region: commercial electricity can approach 1 RMB (0.15USD) in Beijing, but the national average is about 0.67 RMB (0.1USD), while industrial electricity averages around 0.63 RMB nationally.
In China, end users pay a single bundled retail electricity price that already includes the full cost of both generation and delivery. The State Grid company purchasing electricity from generators and settling with them centrally.
Electricity prices are also government-regulated, and any change must go through public notice and approval.
