Vattenfall's Nordlicht I wind farm is Germany's largest offshore wind project. It is part of the Nordlicht I and II cluster. Its size, the amount of electricity it produces and the steel used in its construction are setting the course for a fossil-free future – especially for customers who will be purchasing renewable electricity through PPAs.

December 2025

Power purchase agreements (PPAs) are increasingly offering an opportunity to implement large renewable energy projects without government subsidies – and more and more industrial companies are benefiting from this. There has been much speculation about PPAs in connection with industrial electricity prices. We summarise the advantages of PPAs.

November 2025

Whether it's agri-PV with peas, oats, wheat, barley and 15,000 laying hens or a biodiversity park that goes far beyond the minimum legal requirements for species diversity, we integrate renewable energies into industrial applications and enable electricity partnerships – for example in the form of CPPAs.

October 2025

One of the leading climate researchers has summarised the physical fundamentals of climate change for us. What can we expect in the coming decades, and what does this mean for the actions of commercial enterprises such as ours or our customers? Let us actively shape the change!

September 2025

In our ‘5 Questions...’ section, we highlight current topics from the energy industry or energy trading. This time, we address questions posed by participants in our biomethane webinar. The focus here was primarily on the risks and potential applications of this natural gas substitute.

June 2025

It was actually supposed to start on 11 June - but EPEX Spot has called for the introduction of quarter-hour trading to be postponed until 30 September. Why do quarter-hours make sense in the day-ahead auction and why does the exchange still need some time to prepare? We explain!

May 2025 

At Vattenfall, we invest in battery storage ourselves - but above all, we support our customers in investing and optimizing wholesale storage in the best possible way. In our “5 questions” this time, we focus on topics that our customers often ask us about.

March 2025

The first quarter of 2025 is history. Time to take an initial look back and categorise market developments to date. Important factors were the mild winter, lower gas prices and weakening prices for emission allowances. Nevertheless, the electricity spot market increased significantly compared to the same quarter of the previous year. 

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.

May 2024

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.
