6 FAQs about [Hydropower storage tepco]

How many pumped storage power plants does TEPCO own?

Tokyo Electric Power Company (TEPCO) currently owns a total of 9 pumped storage power plants (including one under construction), which are being operated by TEPCO to meet the daytime peak electricity demand. Table-1 and Fig.-1 show a list of TEPCO’s pumped storage power plants and their locations, respectively. 2. Features of the Project Area

Where are TEPCO power plants located?

TEPCO’s service area includes the Tokyo metropolitan area and the surrounding cities which together comprise one of Japan’s heaviest electricity-consuming regions, but these days new power plants tend to be sited in areas remote from this region because of the scarcity of sites suitable for power plant development.

How many hydro power stations does TEPCO own?

TEPCO owns 163 hydro power stations located in the Tonegawa River system mainly in Gunma and Tochigi Prefectures, the Shinanogawa River system running across Nagano and Niigata Prefectures, and the Sagamigawa and Fujigawa River systems in Yamanashi Prefecture. The total output of these stations is approximately 8,980 MW.

What are mixed pumped storage hydroelectric power plants?

Mixed pumped storage hydroelectric power plants are pondage type hydroelectric power plants added with pumped storage power generation systems to enable them to make large-scale daily adjustments to meet peak demand.

How does TEPCO use natural energy?

TEPCO generates energy from natural sources by building a small power station that takes advantage of a 101-meter drop in the waterway. *Please see our press release for further information.

Can pumped storage hydroelectric power plants be sited without river system conditions?

Because pure pumped storage hydroelectric power plants essentially have no river water inflow into their upper adjustment reservoirs and generate power using water pumped up from their lower adjustment reservoirs only, they can be sited without the need to consider river system conditions as long as the heads are sufficiently large.
