Pumped Hydropower Storage Profits: The Hidden Goldmine in Energy Storage?

Ever wondered why China’s top energy giants like Southern Power Grid Energy Storage and Yangtze Power are racing to build these "water batteries"? Let’s spill the tea: pumped hydropower storage (PHS) isn’t just about energy – it’s a financial puzzle with surprising twists.
