Hydro power generation
Hydroelectric power makes use of the difference in elevation of rivers to produce electricity by harnessing the potential energy. This renewable energy source has long been widely used in Japan, where there are abundant water sources and many swift-flowing rivers. Since our establishment, Renewable Japan has been developing renewable energy business with a focus on solar power. To ensure a stable supply of electricity, as a part of our efforts to diversify the power sources, we acquired Akashiba Hydroelectric Power Plant in Yamagata Prefecture in Feb. 2021, and started hydroelectric power generation business.
Features of hydro power generation
-
It is a clean and environmentally friendly power generation method that does not produce exhaust gases or CO2 during power generation.
-
As it harnesses the power of river water, it can generate stable power, day and night.
How hydro power generation works
The waterwheel is turned by using the potential energy of water in high places.A generator converts the kinetic energy generated by turning the waterwheel into electricity.
Akashiba Hydro Power plant
The Akashiba Power Station is situated in Nishiokitama County, Yamagata and was constructed in 1954 as the first dam owned by the private sector in Yamagata. With abundant water from the Arakawa River (first-class river) system, electricity is supplied stably to local factories throughout the year and is consumed in this area, forming an important power source that enables local production for local consumption.
