Not a single country can cover its demand for energy with its own sources. This is why energy has been traded since the markets were deregulated. It’s a risky business in which dealers have to consider a great many issues.
The weather, global political and economic developments and unexpected power plant outages – all of this can affect supply and demand and, in turn, price. Traders buy and sell energy products on the exchanges and over the counter. In so doing, they ensure security of supply in the event of failed deliveries and supply shortages.
