Lake Tagokura
Tagokura Dam (田子倉ダム) is a gravity dam, on the Tadami River in the Fukushima Prefecture of Japan. It is owned and operated by the Electric Power Development Company (J-Power). The lake which it impounds is known as Lake Tagokura. Statistics The dam is long and high. It supplies a 380 MW hydroelectric power station that is also owned by J-Power.Lake Tagokura has a surface area of and a capacity of . The catchment area is . History Construction of the dam started in 1953 and it was completed in 1959. In order to facilitate the movement of construction material, the existing railway from to was extended to , and a light railway was built from there to the construction site. After the dam was completed, the light railway was upgraded and extended to link to an existing line at , thus creating today's Tadami Line.

Tadami River
The is a major tributary of the Agano River in Japan. Its basin covers and its main stem is extensively regulated and developed for hydroelectric power. The river is located within Niigata, Gunma and Fukushima Prefectures. Dams Starting from the furthest upstream, the river is dammed by: * Okutadami Dam – tall gravity dam, 560 MW * Otori Dam – tall arch-gravity dam, 182 MW * Tagokura Dam – tall gravity dam, 380 MW * Tadami Dam – tall embankment dam An embankment dam is a large artificial dam. It is typically created by the placement and compaction of a complex semi-plastic mound of various compositions of soil or rock.

Otori Dam
The is a concrete arch-gravity dam on the Tadami River, southwest of Tadami in Fukushima Prefecture, Japan. The primary purpose of the dam is hydroelectric power generation and it supports a 182 MW power station. The power station contains two Kaplan turbine-generators. Unit 1 (95 MW) was commissioned on 20 November 1963 while Unit 2 (87 MW) was commissioned on 7 June 2003 as part of a power plant expansion project that included an additional 200 MW generator at Okutadami Dam upstream. The dam is tall and long. Its reservoir has a capacity of which is active (or "useful") for power generation. The reservoir has a catchment area of and surface area of . Of the two generators, Unit 1 has a maximum effective hydraulic head of and Unit 2 is afforded . The design flood discharge of the dam is and its service spillway is controlled by three tainter gates.

Hydroelectric Power Stations In Japan
Hydroelectricity, or hydroelectric power, is Electricity generation, electricity generated from hydropower (water power). Hydropower supplies 15% of the world's electricity, almost 4,210 TWh in 2023, which is more than all other Renewable energy, renewable sources combined and also more than nuclear power. Hydropower can provide large amounts of Low-carbon power, low-carbon electricity on demand, making it a key element for creating secure and clean electricity supply systems. A hydroelectric power station that has a dam and reservoir is a flexible source, since the amount of electricity produced can be increased or decreased in seconds or minutes in response to varying electricity demand. Once a hydroelectric complex is constructed, it produces no direct waste, and almost always emits considerably less greenhouse gas than fossil fuel-powered energy plants.

Gravity Dams
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. 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. Stability of the dam primarily arises from the range of normal force angles viably generated by the foundation. Also, the stiff nature of a gravity dam structure endures differential foundation settlement poorly, as it can crack the dam structure. The main advantage to gravity dams over embankments is the scour-resistance of concrete, which protects against damage from minor over-topping flows. Unexpected large over-topping flows are still a problem, as they can scour dam foundations. A disadvantage of gravi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Energy Infrastructure Completed In 1960
Energy () is the physical quantity, quantitative physical property, property that is transferred to a physical body, body or to a physical system, recognizable in the performance of Work (thermodynamics), work and in the form of heat and light. Energy is a Conservation law, conserved quantity—the law of conservation of energy states that energy can be Energy transformation, converted in form, but not created or destroyed. The unit of measurement for energy in the International System of Units (SI) is the joule (J). Forms of energy include the kinetic energy of a moving object, the potential energy stored by an object (for instance due to its position in a Classical field theory, field), the elastic energy stored in a solid object, chemical energy associated with chemical reactions, the radiant energy carried by electromagnetic radiation, the internal energy contained within a thermodynamic system, and rest energy associated with an object's rest mass. These are not mutual ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dams On The Tadami River
A dam is a barrier that stops or restricts the flow of surface water or underground streams. Reservoirs created by dams not only suppress floods but also provide water for activities such as irrigation, human consumption, industrial use, aquaculture, and navigability. Hydropower is often used in conjunction with dams to generate electricity. A dam can also be used to collect or store water which can be evenly distributed between locations. Dams generally serve the primary purpose of retaining water, while other structures such as floodgates or levees (also known as dikes) are used to manage or prevent water flow into specific land regions. The word ''dam'' can be traced back to Middle English, and before that, from Middle Dutch, as seen in the names of many old cities, such as Amsterdam and Rotterdam. Ancient dams were built in Mesopotamia and the Middle East for water control. The earliest known dam is the Jawa Dam in Jordan, dating to 3,000 BC. Egyptians also built dams, ...

Tadami Dam
Tadami Dam is a rock-fill embankment dam on the Tadami River near Tadami in Fukushima Prefecture, Japan. It was constructed between 1981 and 1989 for the purposes of hydroelectric power generation and controlling the outflows of the Tagokura Dam. It supports a 65 MW power station.
