Green power certificates function as electronic identifiers for transactions of renewable power. Given the uniform nature of electricity, once it enters the grid, its attributes cannot be differentiated by either the grid or consumers. These certificates provide proof of green power usage for their holders.

Each certificate represents 1 MWh of renewable power produced from sustainable sources and can be traded independently from the actual green power. The primary trading platforms for these certificates are the Beijing Power Exchange Center and the Guangzhou Power Exchange Center.
