PHS stands for Pumped hydro storage, an energy abbreviation.
Energy storage method that pumps water uphill to a reservoir when electricity is plentiful and releases it through turbines when power is needed. PHS has long provided the vast majority of the world's grid energy storage, returning roughly 70-80% of the energy used.
Example: The PHS plant can switch from pumping to generating in a few minutes to meet the evening peak.
Usage notes
Bath County in Virginia, with about 3 gigawatts of capacity, is among the largest in the world, and China has built many new plants, including Fengning, the largest. New sites are limited by geography and permitting, so closed-loop designs and batteries are taking a growing share.
