1. kilowatt load averaged over a specified time (usually l5 or 30 minutes). The demand for any given interval is that value of power in kilowatts that, if held constant over the interval, accounts for the same consumption of electrical energy as the real power. The average of the real power over the demand interval. This is commonly identified as the block interval method.

2. (electric power utilization) load integrated over a specified time interval.

3. (installation or system) load at the receiving terminals averaged over a specified interval expressed in kilowatts, kilovolt-amperes, kilovars, amperes, or other suitable units.
