The Bath County Pumped Storage Station in Virginia, USA, has a generating capacity of 3,003 MW — the largest pumped-storage hydroelectric facility in the world, able to switch from standby to full power in about three minutes, functioning as a giant mechanical battery for the electrical grid.
The greatest generating capacity of any pumped-storage hydroelectric facility — a form of grid-scale energy storage that pumps water uphill when electricity is cheap and releases it through turbines when demand is high.
Change a parameter to stress-test whether a proposed result is still inside the published specification. This is an audit aid, not a proof checker.
This record has no editable parameters. Read the formal question and assumptions before challenging it.
Current frontiers derived from accepted Claims.
An observed or demonstrated result; no opposing bound is implied.
The frontier is not sacred
Most progress starts with a disagreement that survives contact with evidence. If you can push the known lower bound up or pull the upper bound down, show us the work.
≥ when you have shown that at least this value is achievable.≤ when you have shown that anything above this value is impossible.No vibes. State the value, define the scope, and link the paper, proof, code, or reproduction that lets another person check it. Editors review every challenge before the public record changes.
