Energy companies ensure the electric grid is appropriately sized for growth and continuously maintained, and they increase power generation capacity as demand increases, always looking for the most efficient mix of hydro, coal, gas, nuclear, wind and solar to drive down the price they charge customers. They don’t have to worry about lobbying politicians as the government has neither the power to regulate the industry nor the power of eminent domain to take your property without your consent for the alleged “common good”.
Water and wastewater corporations act in a similar fashion with respect to drinking water and wastewater infrastructure, as do private entities that build levees, mitigate flash floods, and take other flood control measures.
