10% profit margin says not much. Maximum 10% gain is not true for example because a contracted utility has little pressure to improve services, create new services, invent new energy processes, open or serve new markets. They can go with the generic political will and collect their garanteed 10%. Private enterprise wins or loses potentially big specifically by not doing that. Maximum 10% gain is also not true for example because there is little pressure to "do it right" from an economic outcome point of view (when to plan expansions, how to schedule maintenance). Skipping the extremely politically incorrect example. Maximum 10% gain is also not true for example because the current sector rarely has the opportunity to expand dramatically to support a dramatic new industry. (In that case, the gain would come from the new industry - AND the expanding utility sector) Even the Pacific North West did it the other way around: available surplus energy caused new industry to settle there.
