Why a new type of hydroelectric turbine?

Presentation





Why a new type of hydroelectric turbine?

• No Manufacturer in the world offers a Turbine fitted for heads of less than 2 m.

•The most profitable sites are already built in developed countries.

• The remaining potential is located below 2 m gross head.

• Same comments are valid worldwide
