Write what each word means, using the article.

Do not copy the article. Write two things you learned, the way you would explain them to a friend.

Answers below are taken from the article’s stored facts, so they match what the student read.

1. How tall is Shimogo Pumped Storage Power Station?1,000 megawatts
2. What is the location?Shimogō, Minamiaizu, Fukushima Prefecture, Japan
3. What is the maximum water flow rate?314 cubic meters per second
4. How does the station use water to make electricity?When there is extra electricity, the plant pumps water from the lower Okawa Reservoir up to the higher Ouchi Reservoir. Later, when more power is needed, the water flows back down, turning turbines that generate electricity.
5. Why are there two reservoirs, Ouchi and Okawa, in the station?The two reservoirs use the natural height difference in the mountains. The higher Ouchi Reservoir stores water as potential energy, while the lower Okawa Reservoir receives the water when it is released.

Pumped-Storage Hydroelectricity: An energy storage method utilizing two reservoirs at different elevations to generate electricity by moving water between them.
Reversible Pump-Turbine: A specialized turbine that can operate in reverse, functioning as a pump to move water uphill and as a turbine to generate electricity.
Grid Stability: The ability of an electrical grid to maintain a consistent power supply and voltage, even with fluctuating demand and generation.
Installed Capacity: The maximum output a power station can produce under ideal conditions, measured in megawatts (MW).
