China’s Guangdong Nuclear Power Corp orders BYD Li-ion battery back-up for nuclear plants
7 September 2012
China’s Guangdong Nuclear Power Corp (CGNPC) announced this week the results of the bidding for their largest high-power, high-capacity battery back-up stations to date, with BYD Ltd of Shenzhen winning the bid.
A “National Energy Application Technology Research and Engineering demonstration project”, CGNPC plans to couple these 3.5 MWh back-up Li-ion batteries with their nuclear power stations to deliver power up to 2.5MW levels. The energy storage station will serve as an emergency power source to safeguard workers and protect station equipment from being damaged in extreme conditions where the nuclear plants may lose their electrical supply.
The battery backup system is designed to avert a disaster such as Japan’s Fukushima Power Plant 311 experienced because of a power failure. Technologies that qualified for this bid were all reviewed for their maturity, proven commercial stability and absolute safety and reliability even in the harshest conditions, such as earthquake, tsunami, fire, and radioactive exposure. BYD’s second generation energy storage station can provide reliable “passive” emergency power for Nuclear power plants.
In 2010, BYD launched the first MWh-level Iron-phosphate energy storage station attached to China’s Southern Power Grid. In 2011, this plant was dwarfed by an even larger 36 MWh storage station at China’s State Grid’s “National Sun” project—a renewable, base-load power generation plant.
Currently, there are more than 400 second generation nuclear power units worldwide.

Only 3.5 MWh when the draw is up to 2.5 MW?
That is only ~1.5 hours.
Even Fukushima had 8 hours of battery back-up.
