How this measure is built
- Definition
- Total capacity of pumped storage hydropower projects currently under construction.
- Measure
- One slice of Electricity capacity ( form: level, segment: pumped storage under construction ) . Maximum electrical output capacity of power installations. Region and period are columns on every record, not slices.
- Limitations
- Values are shown as published; StatOrigin does not revise, fill gaps or convert currencies.
- Verification
- Each value, unit, period and place was checked against its source evidence before publication. See the methodology and the corrections process.
