Unit converter — kW, kWh, MW, MWh
kW is power at an instant, kWh is that power for an hour. A 1 MW plant running an hour makes 1 MWh.
① Power — the rate at one moment
- kW
- 1,000
- MW
- 1
- GW
- 0.001
② Energy — the total over time
- kWh
- 1,000
- MWh
- 1
- GWh
- 0.001
- TWh
- 0.000001
③ Output — power × time × capacity factor
Capacity
8.76GWh
1 MW × 8,760 h × 100% = 8,760 MWh
100% means running flat out all year; real values vary by source, site and year. A month is 8,760 h ÷ 12 = 730 h (real months: 672–744 h).
Not in this calculation
- Actual capacity factors — the figure is your own assumption
- Station use and line losses
- Month lengths — a month is taken as 730 hours
