Console every day: "powerstats" in System Error report

Question

Why is there this error report every day in Mavericks console, for ex. today: "powerstats_2013_11_02 02404.... " ?
And the actual report is very long, starting like:
Date/Time:       2013-11-04 00:00:00 +0200

..and so on.
Does anyone know how to get rid of these "endless" reports?  Btw. My MacBook Air doesn't have this same problem.

Thank you for the imformation. Since I am no programer, you might give me further info: if I delete the fine with the CalendarInterval-entry Plist Edit pro complains about a kryptic line. Now: what might be the correct text and line(s) to delete? Before edit the text looks like this:
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">

Thanks for advice. MK
