An electricity market is a system where electricity is bought and sold. It connects electricity producers, like power plants, with consumers, such as homes and businesses. Prices in this market can fluctuate based on supply and demand, meaning that when demand is high, prices may increase, and when demand is low, prices may decrease. In many regions, electricity markets are regulated to ensure fair competition and reliable service. Participants include utilities, independent power producers, and retailers, all of whom play a role in delivering electricity to end-users. These markets can be organized as either wholesale or retail, depending on the level of transaction.
