About the power station
The Daya Bay Nuclear Power Station is the first of its kind in Mainland China. It is one of the earliest, largest and most successful joint-venture projects under the Open-Door Policy.
The station produces about 15 billion kWh of electricity every year. In general, we import 70% of the station’s electricity into Hong Kong. This supply arrangement lasts until 2034. To increase our supply of clean and affordable energy, we increased our imported amount from 70% to 80%. This arrangement lasts until 2023.
Benefits of nuclear electricity
Nuclear power is safe, very reliable and cost-competitive. It does not release any residue or carbon emissions. Our sustainable development of nuclear power will play a key role in combating climate change.
Safety excellence and emergency preparedness
We have always maintained an excellent record in plant reliability, performance and safety since the plant. In 2018, we were the champion in Capability Factors at the EDF Safety Challenge Competition for 11 consecutive years.
Site selection
Daya Bay is located in a seismically stable region. We selected the site according to international guidelines and stringent safety assessment by the National Nuclear Safety Administration.
Plant design
We designed our plant according to the site’s local environment. Its design is able to withstand natural hazards such as tsunamis or earthquakes.
Operational safety
In the event of an emergency due to equipment failure or human error, our auxiliary equipment will step in to maintain the safe operation of the plant.
Emergency preparedness
We have well-established contingency plans at Daya Bay. In the unlikely event of a nuclear accident, we have a mechanism to support communication:
With the general public; and
Between the relevant government authorities in Guangdong and Hong Kong.
Comprehensive monitoring
Our comprehensive monitoring programme safeguards the health of our staff and the general public. Regular checks over the years show that:
There has been no excessive or undue release of radioactivity; and
The effect of radioactive releases on the environment is very low if not negligible.
