The core rules almost provides for something better than the 1/2 A power plant, and I didn't even see it.
It requires stage effects. I don't know (yet) if that matters.
It also requires one change to the rules: the power plant minimum size should be reduced to 2 tons.
Anyway, here it is: apply the "Modified" stage to the Power Plant A. The result:
Not only does this save us 2 tons, it also pushes at 90% of the PPA. Yes, it's not terribly efficient, but in a 10 ton hull, we only need 1t of fuel. That's still better than using a regular PPA.
Unfortunately, that might be abusable. Consider connecting two Mod-A plants together. You get better performance than one A, even taking fuel use into consideration.

Code:
Modified Power Plant A. Rating=0.9. Tons=2. MCr 2.
