Niamey energy storage hydropower station

How will Niamey's new power station work?

The power station, which will be equipped with four Kaplan turbines with nominal unit capacity of 32.5 MW, is designed to generate average annual output of 629 GWh, which is equivalent to about half of the country’s total electricity consumption in 2018. Power will be supplied to Niamey through a new 132 kV double circuit transmission line.

Where is Niger's first hydroelectric dam?

Niger's first hydroelectric dam, Kandadji, is situated 189 km northwest of the capital Niamey.

What is pumped storage hydropower (PSH)?

Pumped storage hydropower (PSH) currently accounts for over 90% of storage capacity and stored energy in grid scale applications globally. The current storage volume of PSH stations is at least 9,000 GWh, whereas batteries amount to just 7-8 GWh.

How does a hydropower station control energy storage?

The leading hydropower station is responsible for further controlling the energy storage among cascaded stations along a river. Finally, with these guidelines in place, detailed schedules can be created for when and how much energy should be stored or used on a quarter-hourly basis.

Should hydropower stations be renovated with pumped storage?

The costs and operational efficiencies of renovating conventional hydropower stations with pumped storage are two key factors that must be considered.

Why do hydropower stations use reservoir storage?

In operations, hydropower stations utilize their own reservoir storage to redistribute uneven inflows over periods of years, months, weeks, days or hours, thereby controlling when and how much electricity is generated. This ability enables them to quickly respond to the increasing demand for flexible power in electrical grids 2, 3.
