How to write a catalog of pumped storage project materials

What are the different types of pump storage?

Pump storage comes in two types: on-river and off-river. A) On-river projects are hydroelectric plants supplied by rivers. B) Off-river projects use two reservoirs at different levels. Water is pumped up from the lower to the upper reservoir when there is surplus power and flows down to generate power when needed.
