If a star destroyer could accelerate at roughly this speed; they are consistently portrayed as being faster than the Millennium Falcon, and we estimate its mass as a 200 meter by 1000 meter cylinder that is 10% solid made out of iron, its engine power alone would be around 2.2 * 10^22 watts.
Trying to quickly reverse engineer that number using Saxton's formula (P=F*c), I got a number that was a little different, but at least within an order of magnitude of yours, which is good enough for now. (Don't know which one was the more correct; maybe we rounded our numbers differently. This time of day, I'm not even sure I did my maths right.)
In any case, the problem with estimating engine power based on acceleration would be that in the EU, we have multiple mentions of Star Wars engines using mass lightening technobabble of the kind that's seemingly become endemic to visual sci-fi in recent years. Which makes estimating the "m" part of F=ma ... difficult, to say the least.
This is a big problem for Star Trek as well as Star Wars. Mass lightening tech is quite probable. What I find funny is that Brian claims things are inescapable, yet we routinely here on this site and on others find all kinds of way around it. The fact is, neither he nor Saxton or anyone else didn't truly try to disprove anything. They made up their minds and went with the numbers they wanted. Furthermore, if you can apply that thinking to Star Wars, why not apply it to Star Trek or any other SF franchise? I mean we do know the mass of the TOS
Enterprise and
Voyager (nearly 1 million long tons and 700,000 metric tons respectively)and we have seen them perform feats of acceleration far in excess of their Star Wars counterparts. The
Enterprise in ST:TMP's run from Earth to Jupiter requires at least a 34,000 m/s², or 3,460 gs acceleration, which if we plug the numbers in:

About 5,800 petajoules. And this from a mid-size Federation starship on impulse power only. If we use the E-D, which we can reasonably extrapolate is 6-24 times more massive than
Voyager or the Constitution-class
Enterprise, the power output gets really scary since the E-D has managed to get from Saturn to Earth in 19 minutes on impulse power only.
