Can a Living Entity placed as Block by procedure store Energy

I am making a mod that makes use of the Energy feature of blocks. I want to make a Power Cable like item that will attach to the surrounding blocks that can accept Energy. This will be so much easier if i can use the Model Layers feature of entities for the different attachment "Shapes" instead of using a procedure that places a different block for each possible combination. But will the Entity being placed as a block still act like a block in the sense of Energy.
