No wonder you're running out of power

.
All those high end modules are breaking your back, and aren't accomplishing anything much. Look at the listing at the bottom of the page, then sort in by descending power. All numbers relating to unengineered modules:
1) thrusters. 7.56 MW, and that isn't going to get better when you plug in grade 5 DDs. No way to save here.
2) shields 4.34 MW. That is one place that is easy to change - and, if you combine it with a few other changes, without too much loss (of course, you could still get better shields by not doing the other things, but that's the point, really - you will need to choose). Since you're running both guardian and regular shield boosters, there's not much point in going for bi-weaves, so just slap a grade 5 enhanced low power on there and drop that to 2.6 MW.
3) The KWS is a power hog. Drop it to C-rated and slap a fast scan grade 5 on it. Instead of 10 seconds at 4 km, you'll now need 2 seconds at 2.3 km - and only a quarter of the power.
4) Your plasma accelerator. I have no personal experience with this, so keep it as it is. But there are at least two mods that will reduce the powerr draw.
5) All those A-rated shield boosters... Swap the for D-rated and mod them with resistance augmented/flow control. Raw shield strength is AFAIK only good against plasmas, and those are easy to evade.
6) Guardian shield reinforcements - nothing to mod there.
7) small stuff.

Now you even have a little bit of spare power for the engineered thrusters
and about effectively 40% stronger shields
