The 2011 Fukushima nuclear disaster in Japan led to the shutdown of nuclear power plants, causing blackouts and fear of electricity shortages. As Japan sought non-nuclear energy sources, renewable energy like solar and wind increased but could not provide stable power alone. To solve this, Samsung SDI partnered with Nichicon in 2011 to create home energy storage systems (ESS). Using Samsung SDI batteries and Nichicon power control systems, ESS provided steady power, maximized solar use, saved costs and was eco-friendly, dominating the Japanese market. Now Samsung SDI aims to be a global ESS provider, starting in Japan.

Almost all of Japan's nuclear power plants
were shut down soon after the disaster.
Having experienced blackouts due to the
disaster, the citizens of Japan began
to fear the shortage of electricity.

4. Samsung SDI Energy Storage System | Adoption of renewable energy
As the need to replace nuclear power plants
with a non-nuclear energy source became
obligatory, energy dependency on eco-friendly
energy sources such as solar and wind began
to increase.

provide the general public with a stable
energy source.
