Unit converter — kW, kWh, MW, 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
