|---|---|
| How it Works: | Gravitational potential energy ↔ kinetic energy ↔ electricity
Water is pumped up hill with excess electrical energy which is stored as gravitational potential energy. When energy is needed, water flows down through the generator to produce electricity. |
| Benefits: |
|
| Challenges: |
|
| Technology Variations: | |
| Applications: | Bulk, long-duration services, power regulation and load following |
| AC RTE Efficiency: | 70-85% |
| Cycle Life: | 60-100 years1 |
| Technology Readiness Level (TRL): | 9 - Fully Mature |
| Installed Capacity: | >160 GW |
