Shintoyone Pumped Storage Power Station
The is a large pumped-storage hydroelectric power plant in Toyone, Kitashitara, Aichi Prefecture, Japan. With an installed capacity of , the plant is one of the largest pumped-storage power stations in Japan. The facilities are run by Electric Power Development Company (J-Power). Like most pumped-storage facilities, the power station uses two reservoirs, releasing and pumping as the demand rises and falls. Midori lake, formed by the Shintoyone Dam, is the upper artificial reservoir, while Sakuma Dam forms the lower reservoir. Shintoyone Dam is a 116.5 m-tall arch dam, while Sakuma Dam is a 155.5 m-tall concrete gravity dam A gravity dam is a dam constructed from concrete or stone masonry and designed to hold back water by using only the weight of the material and its resistance against the foundation to oppose the horizontal pressure of water pushing against it. .... Sakuma Dam was built between 1953 and 1956 to provide water to the Sakuma conventional hydroelectric pow ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Shintoyone Dam
The Shintoyone Dam (新豊根ダム) is a multipurpose dam in the village of Toyone in the Aichi Prefecture of Japan. History The potential of the Tenryū River valley for hydroelectric power development was realized by the Meiji government at the start of the 20th century. The Tenryū River was characterized by a high volume of flow and a fast current. Its mountainous upper reaches and tributaries were areas of steep valleys and abundant rainfall, and were sparsely populated. However, the bulk of investment in hydroelectric power generation in the region was centered on the Ōi River, and it was not until the Taishō period that development began on the Tenryū River. With the completion of the Sakuma Dam, one of the tallest dams in Japan, on the main stream of the Tenryū River, developers turned their eyes to the confluence of the Ōnyugawa (大入川), a major tributary of the Tenryū River, and the Ōchisegawa (大千瀬川) in Aichi Prefecture. The Ōnyugawa was also of i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pumped-storage Hydroelectric Power Stations In Japan
Pumped-storage hydroelectricity (PSH), or pumped hydroelectric energy storage (PHES), is a type of hydroelectric energy storage used by electric power systems for load balancing. The method stores energy in the form of gravitational potential energy of water, pumped from a lower elevation reservoir to a higher elevation. Low-cost surplus off-peak electric power is typically used to run the pumps. During periods of high electrical demand, the stored water is released through turbines to produce electric power. Although the losses of the pumping process make the plant a net consumer of energy overall, the system increases revenue by selling more electricity during periods of peak demand, when electricity prices are highest. If the upper lake collects significant rainfall or is fed by a river then the plant may be a net energy producer in the manner of a traditional hydroelectric plant. Pumped-storage hydroelectricity allows energy from intermittent sources (such as solar, wi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Hydroelectricity In Japan
Hydroelectricity is the second most important renewable energy source after solar energy in Japan with an installed capacity of 50.0 gigawatt (GW) as of 2019. According to the International Hydropower Association Japan was the world's sixth largest producer of hydroelectricity in 2020. Most of Japanese hydroelectric power plants are pumped-storage plants. Conventional hydropower plants account for about 20 GW out of the total installed capacity as of 2007. Conventional hydropower potential of Japan is considered to be almost fully developed, with little opportunity for further capacity increase. In recent years, almost exclusively pumped storage plants were commissioned, significantly increasing the ratio of pumped storage capacity over conventional hydro. The large capacity of pumped storage hydropower was built to store energy from nuclear power plants, which until the Fukushima disaster constituted a large part of Japan electricity generation. As of 2015, Japan is the country wi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Gravity Dam
A gravity dam is a dam constructed from concrete or stone masonry and designed to hold back water by using only the weight of the material and its resistance against the foundation to oppose the horizontal pressure of water pushing against it. Gravity dams are designed so that each section of the dam is stable and independent of any other dam section. Characteristics Gravity dams generally require stiff rock foundations of high bearing strength (slightly weathered to fresh), although in rare cases, they have been built on soil foundations. The bearing strength of the foundation limits the allowable position of the resultant force, influencing the overall stability. Also, the stiff nature of the gravity dam structure is unforgiving to differential foundation settlement, which can induce cracking of the dam structure. Gravity dams provide some advantages over embankment dams, the main advantage being that they can tolerate minor over-topping flows without damage, as the conc ...

Arch Dam
An arch dam is a concrete dam that is curved upstream in plan. The arch dam is designed so that the force of the water against it, known as hydrostatic pressure, presses against the arch, causing the arch to straighten slightly and strengthening the structure as it pushes into its foundation or abutments. An arch dam is most suitable for narrow canyons or gorges with steep walls of stable rock to support the structure and stresses. Since they are thinner than any other dam type, they require much less construction material, making them economical and practical in remote areas. Classification In general, arch dams are classified based on the ratio of the base thickness to the structural height (b/h) as: * Thin, for b/h less than 0.2, * Medium-thick, for b/h between 0.2 and 0.3, and * Thick, for b/h ratio over 0.3. Arch dams classified with respect to their structural height are: * Low dams up to , * Medium high dams between , * High dams over . History The develop ...

Sakuma Dam
The is a dam on the Tenryū River, located on the border of Toyone, Kitashitara District, Aichi Prefecture on the island of Honshū, Japan. It is one of the tallest dams in Japan and supports a 350 MW hydroelectric power station. Nearby a frequency converter station is installed, allowing interchange of power between Japan's 50 Hz and 60 Hz AC networks.

Electric Power Development Company
The , operating under the brand name J-POWER, formerly , is an electric utility in Japan. It mainly produces electricity from coal and hydroelectric power stations. It also has a few wind farms and is currently building a nuclear plant in Ohma, Aomori prefecture, that is scheduled to begin operations in November 2014. J-Power is the sole operator of the transmission lines connecting the four main islands of Japan. History After World War II, as a part of many changes implemented, the Supreme Commander of the Allied Powers ordered the dismantling of , which at the time provided electricity to all of Japan with a semi-governmental status. This was broken up into a number of utilities, which have become Japan's modern electric utility companies. However, in the battered state of post-war Japan, there were few investors out there to put money in these new companies, and certainly not enough to allow for sufficient R&D of power sources that Japan needed to keep up with the dema ...
