Pumped hydro storage: Relationships

Every element and industry that Pumped hydro storage is linked to, and how. Each pair has its own card explaining the relationships between the two.

  • AC transmission: Pumped storage plants are the grid's oldest form of large-scale storage: they pump water uphill with surplus grid power and return it at peaks, and India is building a pipeline of them, about 7.4 GW running and 15.9 GW under construction in 2026, to balance solar. (researched)
  • Generators and alternators: Energy flows from pumped hydro storage to generators and alternators.
  • HVDC links: Energy flows from HVDC links to pumped hydro storage.
  • Hydropower dams: Energy flows from hydropower dams to pumped hydro storage.
  • Water: Pumped hydro storage needs water.
