Electricity is created by converting different types of energy like natural gas, nuclear power, coal, wind, and solar. Power stations are designed differently, and electricity markets have changed from deregulation to re-regulation. The process of electricity involves production, high voltage transport, and low voltage transport. There are two main market structures for electricity: pools and bilateral markets. The price of electricity depends on its physical infrastructure. Utility companies, generators, suppliers, industrial consumers, and non-physical participants are the main players in electricity trading.
