Energy utilities are companies that provide essential services related to the generation, transmission, and distribution of energy. They typically focus on electricity, natural gas, and sometimes water services. These utilities ensure that homes and businesses have a reliable supply of energy to meet their needs. Energy utilities operate through a network of power plants, substations, and pipelines. They are regulated by government agencies to ensure fair pricing and reliable service. Examples of energy utilities include Duke Energy, Pacific Gas and Electric, and Con Edison, which serve millions of customers across various regions.
