These markets enable energy producers, traders, and consumers to meet their energy needs in real time while ensuring flexibility and efficiency.
Day-ahead
The day-ahead electricity market is a trading market where energy is traded for the next day—that is, the „day ahead.“ Participants have the opportunity to submit their electricity bids or requests for delivery the next day. An auction takes place on the day-ahead market, during which energy producers submit bids specifying the amount of energy and the price at which they are willing to supply electricity the next day. These bids are collected, and the market price is determined based on supply and demand.
That is why the day-ahead market is important for energy planning and procurement. Energy suppliers and traders use it to organize their electricity deliveries in advance and ensure that the energy supply meets consumer demand.
At the same time, risk management takes place. Energy producers and traders use this market to hedge against price fluctuations. By entering into fixed-price contracts, they can estimate their profits and losses.
Intraday
Unlike the day-ahead market, the intraday market refers to trading that takes place within the same day—that is, „during the day“ (German: „intraday“). The intraday market thus enables real-time energy trading. Participants can continuously adjust their energy supply and demand to respond to unexpected fluctuations in demand or supply.
Intraday trading is also important for the integration of renewable energy, since production from these sources is weather-dependent and therefore highly volatile. Generation forecasts are only accurate shortly before delivery. The forecast error must therefore be corrected on a short-term basis. Energy producers can feed excess energy into the grid during intraday trading or purchase additional energy when production is low.
Trading in Flexibilities
Both markets—the day-ahead and intraday electricity markets—are essential components of today’s energy trading. They enable the efficient and flexible balancing of supply and demand, as well as the integration of renewables into the power grid. Ultimately, through its algorithm and AI-supported trading of intraday and day-ahead electricity flexibility, ESFORIN helps strike the delicate balance between security of supply and the integration of renewables. Together, we are thus enabling the expansion of renewables while simultaneously reducing energy costs and CO2 emissions.
