pumped-storage power station
Let an agent explain pumped-storage power stations and how they work, describe their role in grids and renewable integration, identify notable stations and capacities with sources, and present environmental and economic issues with attribution.
Research draft, second pass
A second pass drafted this model: the structure a model of this thing needs, and what is known about it in the world. The line under this one says how the second half was obtained - researched against sources, or recalled without web access, in which case nothing here was read anywhere and every claim is a lead to verify. Unreviewed either way.

Purpose and description
Let an agent explain pumped-storage power stations and how they work, describe their role in grids and renewable integration, identify notable stations and capacities with sources, and present environmental and economic issues with attribution.
A hydroelectric facility that stores energy by pumping water from a lower reservoir to an upper reservoir when electricity is cheap or abundant and releasing it through turbines to generate electricity when demand is high, using reversible pump-turbines, and providing the largest share of grid-scale energy storage worldwide; pumped-storage stations balance supply and demand, support integration of variable renewable generation, and require suitable terrain, water and environmental approval.
What it is for: Storing grid energy by pumping water uphill.
It can be explain operation; describe grid role; identify stations; present issues.
Distinguishing features
Reversible pump-turbines
Two reservoirs
Grid balancing
Large scale storage
What it looks like
Two reservoirs at different heights connected by tunnels and a powerhouse.
How it is recognised
Reversible hydro storage between two reservoirs
Pumping at low demand, generating at high demand
Conventional hydro stations only generate; batteries store chemically
