4 FAQs about St johns hydroelectric energy storage project

What is pumped storage hydropower (PSH)?

Pumped storage hydropower (PSH) is a type of hydroelectric energy storage. It is a configuration of two water reservoirs at different elevations that can generate power as water moves down from one to the other (discharge), passing through a turbine. The system also requires power as it pumps water back into the upper reservoir (recharge).

Are alternative hydroelectric energy storage systems economically viable?

The current study assesses the potential techno-economic viability of two alternative hydroelectric energy storage systems - a building-based pumped hydro system, and a building-based gravity module system. The levelized electricity cost and variable storage cost are used as performance metrics in the study.

How does pumped storage hydropower work?

PSH acts similarly to a giant battery, because it can store power and then release it when needed. The Department of Energy's "Pumped Storage Hydropower" video explains how pumped storage works. The first known use cases of PSH were found in Italy and Switzerland in the 1890s, and PSH was first used in the United States in 1930.

Will Statkraft buy 450 MW Red John pumped storage hydro scheme?

Norwegian green power giant Statkraft has announced its intentions to buy the 450 MW Red John Pumped Storage Hydro Scheme in Loch Ness. The facility will join Statkraft's already impressive Scottish renewables portfolio. Our daily news digest will keep you up to date with engineering, science and technology news, Monday to Saturday.
