WHOLESALE MARKET
The vast majority of production is still based on conventional fuels, ie coal and lignite. There is also an increase in the share of wind and other renewable energy sources. In the case of energy producers, the main forms of electricity sales are sales within regulated markets, where the leading role belongs to the power exchange and trading companies. In case of trading companies, they mainly sell energy to other trading companies and to final customers. They also provide direct sale to the power exchange, to a lesser, but still significant extent.
RETAIL MARKET
The distribution market operators, including distribution system operators (DSOs) and electricity distributors (trading companies), are retail market participants, alongside end users (both households and enterprises).
IRiESD is very important for the functioning of the retail market. These instructions lay down the rules for the operation of the retail electricity market, including changes in the seller, rules for determining and transmitting measurement data by the DSO, changes of entities responsible for trade balancing, and rules of dealing with the loss of the existing retailer by the customers in the household (reserve sale). Electricity consumers are entitled to receive electricity continuously and reliably from the selected electricity supplier.
