What are the most energetic lightning "superbolts" ever measured?

TL;DR

Highest known energy of lightning on Earth, directly measured or estimated by other means like e.g. satellite observation.

Hi! I would be interested in properly referenced data about the most powerful / energetic lightning bolts on Earth to get a good idea about their maximum possible order of magnitude (maybe depending on location?) Both direct measurements or indirect but well-founded estimates (e.g. satellite observations) are OK. Can you help me, please?

Have you searched for papers about superbolts ?

For a single strike event the specification should be the total energy discharge in joules.
It seems many reporters wrongly refer to power in watts, but not the discharge time.

... “One lightning stroke even exceeded 3 terawatts of power—thousands of times stronger than ordinary lightning detected from space,” ...

Yes I have, and I didn't find anything useful. That's why I came to ask.

Indeed.

Yep, that's the kind of info I found ---useless without the discharge time. Also in volts, in amps... but never in joules or anything that let me calculate the joules.

I notice that the EU standard for lightning protection, EN-62305 page 35, quotes a figure of 10 MJ/Ohm for the energy delivered in 10% worst case flashes.
