Small hydropower business

～Background of small hydropower development attracting the most attention～

01Have mature technology

It has the longest history among renewable energies, and its technology is already highly established.

02Relatively stable power generation

Since the flow rate can be secured regardless of day or night, power can be generated continuously.

03Long-term operation possible

Once a power plant is built, it is expected to generate power for decades thereafter.

04FIT purchase price is high

The procurement price for fiscal 2020 is 29 yen/kWh for 200 kW or more and less than 1,000 kW, which is set at a high level compared to overseas purchase prices such as Germany, France, and Spain.

～Issues in small hydropower development～

Investigation period

It is greatly affected by the conditions such as usable water volume and effective head of the region (point). A long-term survey is required on the river conditions before the start of the project.

Law investigation

Discussions cover a wide range of topics, including consideration for the environment, coordination of water rights, and confirmation of ordinances.

Efforts to develop small hydropower

Risk hedging through thorough feasibility studies

During the feasibility study, we carefully conduct preliminary investigations and flow rate observations.
We are striving to improve the accuracy of business feasibility evaluations by focusing on consideration of laws and regulations.

Important things in promoting commercialization

The most important thing in promoting commercialization is the relationship with the local community.
We believe that the relationship between people and nature is the most important point in order to make local people feel at ease and to proceed with development. By respecting, appreciating, and understanding people and nature, we can determine what is required of us today and put it into practice. We make it a point to treat each case with respect.
