  1. 01 Installed

    Installed: 13,625 MW

    Nigeria’s 28 grid-connected power plants have 13,625 MW of installed capacity. Each square is 100 MW.

  2. 02 Available

    Available: 4,458 MW

    On average in the quarter, less than a third of it could run: a plant availability factor of 32.7%.

  3. 03 Delivered

    Delivered: 4,113 MWh an hour

    That is what the grid actually generated, on average, each hour of the quarter: 8,883 GWh in total. The red squares were available but not generated.
