Honestly, "power plant" does sound like a mistranslation; perhaps it was just suppose to be called a power source, or something to that effect. It could be some sort of gem; artwork is too low poly to tell. Being low-poly it does look like a gemstone to me. But being low-poly just makes identifying it ambiguous. It could be some sort of battery, or some sort of crystal that gives power. It could be a Chaos Drive which is both crystal and technology.
