Voice assistants, navigation systems, facial recognition – we already use artificial intelligence everywhere. It is also used in electricity trading, because increasing dependence on the weather means that the demand for data is constantly growing. This complexity is almost impossible for humans to manage. We explain examples of how AI is used.

June 2025

The energy market was extremely unsettled in the second quarter of 2025 and was characterised by geopolitical news: The markets were influenced by the USA's unstable tariff policy, the war in Ukraine and hopes for tentative talks between the warring parties.

April 2025

Negative spot prices - a gift is still too expensive? In 2024, the day-ahead prices on EPEX SPOT were negative in 457 hours - this corresponds to five per cent of the 8,784 hours of the year. During these hours, an electricity producer has to pay money for the electricity it generates and the buyer receives the money. A topsy-turvy world that is becoming increasingly common and which we want to take a closer look at.

We have been writing newsletters for our customers for many years. We have therefore rummaged through our archives and would like to regularly offer you exciting and amusing reviews of the energy industry and Germany 20 years ago.

February 2025

The term ‘dark doldrums’ refers to days with little sun and wind and is often used to express a certain scepticism towards renewable energies. But what is behind it? Do the high prices on such days really mean that the electricity market is not working? 

December 2024

It reappears at the end of the year, unasked and seemingly without reason - in various contexts, including the energy market: the ‘year-end rally’. The question arises as to where the impetus comes from and which products in the energy market have been affected by the rally.

November 2024

More and more electricity is being produced in renewable energy plants. Regulatory adjustments and new markets or products are required in order to integrate these into the market as efficiently as possible. The role of the electricity exchanges is of central importance here. This was particularly evident in the summer when there was a breakdown at EPEX. We look forward - and back.

September 2024

What was going on? It seemed as if all the bears were on vacation at the height of summer and the bulls had taken over the commodity markets. An astonishing price rally - there was no sign of a summer slump. In the meantime, however, calm has returned.

August 2024

Guarantees of origin, European green electricity labels, hourly granularity, simultaneity of green electricity supply and generation, optional coupling of GoOs - are you still keeping track? We shed light on all these topics as well as current developments - and of course their impact on consumers and system operators.

Price zone splitting: The term comes more from the vocabulary of energy market experts, but has also appeared in the media in recent weeks. While politicians from the northern federal states consider price zone splitting to be absolutely necessary, politicians from the south see it as a disadvantage for their industry. We try to explain the splitting and the possible effects.

March 2024

Electricity prices have fallen sharply on both the spot market and the futures market since the beginning of the year. The reasons include the low demand for gas with well-filled storage facilities. The outlook is also currently more in favour of the bears than the bulls on the market.

February 2024

Battery storage systems are a fundamental factor for the success of the energy transition. In addition to security of supply, they bring further advantages - for example in terms of revenue potential in the balancing energy market or in arbitrage trading. At Vattenfall, we combine historical experience with innovative concepts.
