The current operator page says Foyers pumped storage uses two 150 MW reversible pump-turbines. The Power Station Dictionary maps exactly FOYE-1 and FOYE-2 and separately identifies the 5 MW Foyers Falls station, so this is per-machine evidence. The 160 MW registry reference remains separate.

Operator capacity sourceWhole-site registered total: 320 MW, including retired units.
Registered capacity is the value retained in the committed BM-unit source snapshot. “Not retained” means the registry no longer supplied a positive figure; it does not mean the unit historically had no capacity. If a unit with a retirement event publishes a non-zero live declaration, the live declaration keeps it in the operating fleet pending review.
