Opinion Exchange

We do not only trade power, we also exchange ideas

The rapid rise of renewable power generation has already fundamentally changed and continues to disrupt the traditional energy landscape. In markets such as Germany the disruption has reached levels that the traditional approaches where different types of conventional plants were dispatched to meet variable demand can no longer apply. In our Blog OPX, we want to exchange opinions on the energy system of the future and share our experience from and our view on a market that already has transformed to a great extend in the past years.
India Power, India Power market

Next Stop: India

Our new series of blog posts covers power markets throughout the world. Our next stop is India – Ravi Vaidya is writing his master thesis on Non-European Flexibility Markets at Next Kraftwerke as part of our Innovation & Development team. Together with Jonas Simon, who has just been to India on a business trip, they discuss the Indian energy market.

Spotlight NEMOCS: Setting up a VPP with Ecotricity

Ecotricity from Great Britain is the first green electricity company providing green energy solutions since 1996. For their future projects, the Stroud based company turned to Next Kraftwerke for setting up a Virtual Power Plant based on its software-as-a-solution NEMOCS. We asked Mark Meyrick, Head of Trading and Smart Grids at Ecotricity, and Tobias Weghorn, NEMOCS product specialist at Next Kraftwerke, about the first steps in setting up a VPP of their own.
Krautz and Romberg investigating the energy sector in Japan

Next Stop: Japan

Our new series of blog posts covers power markets throughout the world. To kick things off, Alexander Krautz and Tobias Romberg discuss their trip to Japan.

Who is disrupting the utility frequency?

On 10 January 2019, the utility frequency of Europe’s power grid dropped to 49.8 hertz. Many factors contributed to the near-blackout that evening, but the incident is not the only one in recent weeks that has shaken the grid.

Renewable Energy Island - Part 2

In the second part of our series, we will talk about different concepts for Virtual Power Plants on islands and island groups for providing a sustainable and secure power supply.

Renewable Energy Island - Part 1

Somewhere in the big blue ocean, there lies an island that can serve as a blueprint for the approach to tackle the challenges of climate change with a self-sufficient supply through renewable energies.
electricity fluctuations, reliable supply

Afraid of the dark

In the German language, there is a word that refers to the fear of having inadequate sunshine or wind to maintain a viable supply of renewable energy: dunkelflaute. The dramatic connotation of the word may be lost a bit in translation, but essentially, dunkelflaute means “a dark lull".

Towards a more democratized energy world

This interview with Jochen Schwill (CEO of Next Kraftwerke) was first published in The Beam #5. Jochen Schwill (CEO of Next Kraftwerke) talks about the fundamentals of a Virtual Power Plant and the idea behind it.
Virtual Power Plants lead Energy Markets of the Future

The dance of generation and demand

Flexibility is the defining principle of tomorrow's electricity market: Helen Steiniger analyses the transition from inflexible concepts of the past to the dynamic electricity markets of the future.
SAIDI - lights don't go out

SAIDI – when the lights (don't) go out

More renewable energy means less grid stability – this concern is often repeated by critics of renewable energy. But how is the stability of the grid actually measured?
Amani Jonas, Power Trader

Decentralized energy, seen through the eyes of a power trader

A successful energy transition is dependent on integrating decentralized energy systems. To clarify important questions regarding decentralization – including the upsides and challenges for energy systems – we spoke with Next Kraftwerke’s in-house power trader, Amani Joas.
Leveraging the potential of VPPs by shifting power production and consumption

First shift, then store

In our future energy systems we will pretty often see times where, let’s say, a sudden storm front brings heaps of cheap and green and beautiful but, alas, in that particular time unneeded wind power into the system. And we will see times where the opposite happens: a sudden shortage of wind and solar power. What can we do about it?

A storm turns to gas

Winter storm Axel, which set the current wind energy record in Germany, was also the source of a large wind power excess in Germany - and a considerable amount of hydrogen gas for the municipal utility company in the town of Hassfurt. There, the power-to-gas (PtG) installation, owned jointly by the city utility and Greenpeace Energy, stored the excess and particularly cheap wind energy in a matter of seconds as hydrogen wind gas.

How to balance supply and demand on new electricity markets

Electricity markets around the world are experiencing a fundamental change: the rapid rise of renewable power generation. In some places the power generation of renewables is occasionally exceeding the total demand in the electricity grid.

Digitalization: Where are the German digital utilities?

In Germany, a lot has been written about two energy megatrends of our time, liberalisation of energy markets and decentralisation of the energy landscape. What we think has been neglected is a third megatrend: digitalisation.
