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.

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?

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.

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?

Power to Gas Unit turns excess Wind Power to Hydrogen

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.
