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
How is TEPCO reducing power generation cost?
TEPCO is minimizing the overall power generation cost of the power network as a whole by utilizing its pumped storage power plants, whose unit cost of power generation is lower than the unit cost of extra-burning at oil-fired power plants during daytime, and achieving an “electricity storage” effect.
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 big is TEPCO's Kannagawa pumped-storage plant?
Kannagawa, which is TEPCO’s ninth pumped-storage plant, bumps up against what may be the technological limits of building such facilities (details to be presented later). However, with an expected rated capacity of 2,820 MW, KHP’s design represents the largest plant of its type in the world.
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.
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.
