From http://www.atmel.com/atmel/products/prod29.htm :

Power Metering

Atmel has a line of products for the emerging digital
power metering market.
.
.
.
The power meter chips are easily programmed to
measure active, reactive and apparent phase power.
Phase power-factor, phase voltage, phase current and
line frequency are also measured simultaneously.
Based on the individual phase power, total active power
is determined.

The power values are calculated over one line frequency
cycle. The negative and positive results are accumulated
in different registers, which allow for separate billing of
imported and exported active energy. Reactive power results
are sorted depending on whether a capacitive or inductive
load is applied.
