BEIJING - China has set the benchmark on-grid nuclear power price at 0.43 yuan (7 US cents) per kWh for newly-built reactors across the country, the National Development and Reform Commission (NDRC) said Tuesday.

The rate, which is charged by power plants to grid operators, had previously varied from project to project.

The NDRC, China's top economic planner, said the move will facilitate the healthy development of nuclear power and help guide investment flows into the sector.

The price will be kept relatively stable, the NDRC said, adding that it will make periodical assessments and price adjustments according to technology advances and changes in costs and market demand and supply situation.
