| kVA | = | kilovolt amperes |
| kW | = | kilowatts |
| kWh | = | kilowatt hours |

The three reliability performance measures are defined as follows:
SAIDI is the total consumer minutes lost/total consumers (average interruption for all consumers).
SAIFI is the total consumers affected/total consumers (average interruptions per year for all consumers).
CAIDI is the total consumer minutes lost/total consumers affected (length of average interruption).
