Electricity Forward Agreement

Electricity Forward Agreement (calendar) (short: EFA system) is a calendar used to specify load profiles when trading on the electricity market.

It was officially only valid until October 2014 but is still abundantly used among commodity traders.

[1][2] One distinguishes between weekdays WD and weekend WE since the electricity consumption is clearly lower on Saturdays and Sundays.

An EFA-week WK consists of five WD and two WE-days.

Due to the existence of leap years, some EFA-Decembers have six weeks (e.g. 2004 and 2009), a strong difference from the commonly used Gregorian calendar system, where February is the leap month.

A daily load profile usually consists of base load , peak load and possibly several hourly forward contract (in orange).
