It is good. But it is bad-formatted, so no one standard parser could parse it.
It contains unquoted empty values like , , ,
Also it doesn't escape double quote symbols inside the values.

It doesn't escape commas inside the values. This is especially important for some locales
where comma is used as decimal separator in floating-point numbers. So I prefer to run PowerTOP
like this:
LC_NUMERIC=en ./powertop ...

It doesn't escape space characters inside the values.
It lefts hanging commas in the end of the string.
Etc.

So the CSV-report of the PowerTOP doesn't conform to any CSV standards.
