Power plants and power trading are usually scheduled in full hours and therefore during the first 15 minutes of hours things ramp up and down. Because of the assymetry in the frequency/power regulation and the fact that you can shave your margins, plats usually ramp down faster than they ramp up, causing these very recognizable dips. -- Poul-Henning Kamp | UNIX since Zilog Zeus 3.20 [email protected] | TCP/IP since RFC 956 FreeBSD committer | BSD since 4.3-tahoe Never attribute to malice what can adequately be explained by incompetence. _______________________________________________ time-nuts mailing list -- [email protected] To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there.
