Energy companies really hate small renewables. They love nuclear and fossil fuels. Why? Renewables can be deployed in decentralised ways. That hurts their bottom line as they get reduced to taking care of distribution through their grids. But they want to control the input, not the distribution. They have focused on centralising electricity generation. That way they can simply make more money. That's why they oppose or actively try to fight microgrid solutions. Decentralisation is bad for them.
