Hydro-Quebec, Sony in storage JV

Canada’s Hydro-Québec and Sony Corporation have formed a joint venture to research and develop a large-scale energy storage system for electric grids that will help integrate wind and solar power.

The two sides expect to establish a new company for this purpose in June.

Hydro-Québec will bring to the partnership its operation and control technologies for electric power supplies as well as lithium-ion battery material technology.

Sony will bring control technologies for highly safe, reliable, olivine-type lithium-ion iron phosphate rechargeable batteries and highly scalable module systems.

By combining these strengths, the new company intends to research and develop a highly safe and reliable system for utility-scale applications, as well as battery material technology suitable for use within electric power systems.

They believe the technology will have a wide variety of applications such as meeting excess demand during peak times at electric power substations, and to secure a stable power supply in case of outages or disasters..

Forecasts indicate that future demand for large-scale energy storage systems will also increase through integration of intermittent sources such as solar and wind.
