Source page: https://www.materialinsights.org/energy/e_pumped_hydro/links/

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](https://www.materialinsights.org/links/ac-transmission-and-pumped-hydro-storage/): 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)*
