Pumped water storage project

What is pumped storage hydropower?

Pumped storage hydropower (PSH) is the most dominant form of energy storage on the electric grid today. It plays an important role in integrating more renewable resources onto the grid. PSH can be characterized as open-loop or closed-loop, with open-loop PSH having an ongoing hydrologic connection to a natural body of water.

What is pumped storage hydropower (PSH)?

Pumped storage hydropower (PSH) is the world's largest battery technology, accounting for more than 90% of long-duration energy storage globally, surpassing lithium-ion and other battery types. PSH is a closed-loop system with an ‘off-river’ site that produces power from water pumped to an upper reservoir without a significant natural inflow.

What is the energy storage capacity of a pumped hydro facility?

The energy storage capacity of a pumped hydro facility depends on the size of its two reservoirs. At times of high demand - and higher prices - the water is then released to drive a turbine in a powerhouse and supply electricity to the grid. The amount of power generated is linked to the size of the turbine.

What is a closed-loop pumped storage hydropower system?

A closed-loop pumped storage hydropower system (PSH) is one where reservoirs are not connected to an outside body of water. In contrast, open-loop systems connect a reservoir to a naturally flowing water feature via a tunnel.

What is the main source of energy for pumped hydropower storage?

Pumped hydropower storage uses the force of gravity to generate electricity using water that has been previously pumped from a lower source to an upper reservoir. The technology absorbs surplus energy at times of low demand and releases it when demand is high.

What is the Ontario pumped storage project?

As Ritchie noted: “The Ontario Pumped Storage Project is a long overdue energy initiative with real benefits for the Indigenous people of the land.” If developed, the 1000MW facility would be co-located on the existing Canadian Army’s 4th Canadian Division Training Centre, north of Meaford in Ontario.
