Guangdong province has started to vary tariffs for industrial users based on the time of electricity consumption, according to a report on State Power's website. The move is designed to ease the strain on the grid and reduce power shortages during peak times.
The peak-loan times are 7am to noon and 7pm to 10pm; the base-load times are noon to 7pm and 10pm to 11pm. Peak period tariffs have been pitched at 1.5 times base-load and low-load tariffs are half the base-load.
