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.
Energy Only Market Trading

The energy-only market (EOM)

You don't need to look far to find an energy-only market (EOM). Since power markets were liberalized in the late 1990s, the energy-only market has become a well-established market design in many European countries.

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.

What is a Virtual Power Plant?

In a Virtual Power Plant, decentralized units in a power network are linked and operated by a single, centralized control system. When integrated into a Virtual Power Plant, the power and flexibility of the aggregated assets can be traded collectively.
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.
