think i remember something about them having their own fossil fuel
power generators...

They used to have their own power generation, but take it from the
National Grid now.

Indeed they used to generate all their own power - the main power
station was at Lots Road in Chelsea. And as you say, they do take
most
of their power from the National Grid now- but the Greenwich power
station has been kept as a back-up.

Yes but even when they still ran Lots Road it only supplied traction
current, and most of the station platform power would come from local (i.e.
grid) supplies. So in the event of a long grid power cut most of the
underground stations would be closed anyway.
