Do the contractual conditions allow you to modify or cancel your energy contract? Be on the lookout for opportunities and observe the fluctuations in electricity and gas prices. However, this monitoring requires a good understanding of the complex mechanisms of energy markets.
Energy suppliers source their electricity and gas on European wholesale markets. Transactions are organized:
As in any market, prices fluctuate depending on supply and demand. They are also influenced by other factors: the production cost of the last power plant called, the prices of other financial markets (oil, CO2) or the geopolitical context.
On the energy markets, two types of products are traded.
Spot products are purchased by energy suppliers on the Spot market for same-day delivery (sub-daily products, Intraday or Within Day) or the next day (daily products or Day-Ahead).
The price of Spot products is particularly volatile. The price of electricity is fixed every day before 13:00 according to supply and demand almost in real time.
Forward products are purchased by suppliers on wholesale markets several weeks, months, or even years before actual delivery. The price per MWh is fixed and negotiated at the signing of the contract.
In electricity, a distinction is made between baseload products, for businesses that require consistent power all year round, and peakload products, for businesses that call for power mostly from 8 am to 8 pm from Monday to Friday.
