Feed two new buildings

[greystar13]

Hi, I have a question I hope someone can help me with.I'll lay out what I've got first. I have two new 20 X 25 buildings in my back yard that I need to feed power. I have a GE breaker panel outside on the wall of my house below my meter that has double breakers that feed power to my central heat/air unit and to my house. a 50 amp breaker for heat strip, a 40 amp breaker for unit, a 100 amp for breaker panel in house and a 30 amp breaker that I'm not sure about( I haven't checked to see what the 30 amp powers).This panel is not accessible to new buildings due to paved drive. In the house is an old Federal Pacific breaker panel with no main breaker that has a 50 amp double breaker, 10 ea. 20 amp breakers, and 2 ea. 30 amp breakers.
New building "A" will have lights, 5 110V outlets, and 1 220V outlet for window heat/air unit. Building "B" will have lights, 5 110V outlets, and 1 220V outlet for window heat/air unit. Building B will be used as a shop and will over time have shop equipment installed, such as drill press, bench grinder, air compressor, etc.
I plan to upgrade my house breaker box regardless of how I power the buildings. I've heard some bad things about the Federal Pacific Stab-Lok panels and would feel better with an upgraded house panel.
With all that said and with cost in mind would I be better off A) Upgrade my home breaker panel with new 100 amp panel and feed new buildings from this panel. B) Upgrade my service to 200 amp, install 200 amp breaker panel in home, and feed new buildings from this panel. C) Upgrade my home breaker panel with new 100 amp panel and have electric company install new service to feed buildings.
Thanks for any help or info.

How many Electric Meters do you want? Consider a 200 hundred amp service and panel for your residence. The FPE StabLocs have earned a bad reputation. The new panel will eliminate this problem and will probabaly have ample capacity to feed sub panels in your two out buildings.

You might consider an overhead run to the outbuildings, even if you need to set a pole, that you can put a dusk to dawn light on.

Check out how farms are wired, every building does not need to have its own service from the utility and meter.
