I think the first question, as mentioned, in one of the previous comments, is your ___location. There are many opportunities in smaller, distant communities that don't have grid service, or don't have good, grid service. Those are places that have room for ideas and opportunities, hence business feasibility. Things like small river turbines, or other combined power sources, possibly wind and solar, even fuel generators as back up. The systems are not really complicated, depending on the end user. Obviously you are not trying to compete with the city of Austin or Dallas, Texas. But tiny remote villages, need electricity. Start small, and as with most successful business, then grow. Find a niche. Then expand when you see the need or opportunity. In the beginning, people without power, are happy to charge cell phones, or power a well pump. Great idea!
