Energy Institute: supply gaps in the electricity market possible by 2030
By Die kalte Sonne
(Translated by P. Gosselin)
The study by the Institute of Energy Economics at the University of Cologne (EWI) reads differently than the very optimistic forecasts one so often reads in the media.
With the expansion of renewable energies, the weather dependency of electricity generation in Germany is increasing. A new analysis shows that the security of electricity supply in this decade is currently not guaranteed in all extreme weather situations. Decisive factors here include the rising demand for electricity due to progressive electrification, the dismantling of fossil power plant capacities and the relatively slow expansion of renewable energies.
This is the result of a new analysis by the Institute of Energy Economics at the University of Cologne (EWI) on behalf of the Society for the Promotion of the Institute of Energy Economics at the University of Cologne. In the publication ‘Analysis of Supply Security up to 2030’, a team from the EWI examines in which (historical) weather situations the power supply is secure at all times and under which circumstances supply gaps could occur in the course of this decade.”
It’s apparent the scientists also do not assume that we have “storage facilities galore” like activists such as Claudia Kemfert often claim. For the study, weather data were taken from a period of 34 years. That is statistically climate.
An analysis of weather data from 1982 to 2016 shows that supply gaps could occur in particular in weather situations with strongly below-average wind availability in northern and central Europe and significantly limited solar radiation in southern Europe. These two weather anomalies occurred in combination, for example, in January 1997 and in December 2007 over an extended period of at least seven days.
For such extreme weather situations for power generation, the EWI team analyzed and quantified the possibility of supply gaps for the years 2025 to 2030 in different scenarios of power system development. In doing so, they examined different paths to coal phase-out, renewable energy expansion, availability of electricity imports and storage capacities, and the degree of electrification between 2025 and 2030.”
Keyword “storage facilities galore”: For natural gas and hydrogen, they also seem to have room for improvement, as reported by Die Welt. According to Müller:
The capacities for storing natural gas and hydrogen are not sufficient, according to the Federal Network Agency. ‘When the immediate crisis is over, Germany should take another close look at whether we actually have the storage facilities everywhere that we would like,’ says the agency’s head, Klaus Müller, in an interview with the Augsburger Allgemeine newspaper.
In the future, hydrogen will be increasingly needed in addition to natural gas. According to Müller, the development of a hydrogen network must begin now. The Federal Network Agency, the government and many municipal utilities and energy suppliers are already planning this. Germany has a widely ramified gas network that can be used in principle, he said. ‘But it can’t simply be converted one-to-one. Natural gas out and hydrogen in, that doesn’t work without any further ado.’”
====================================
Note from NTZ: The way things are going now, the grid probably will crash very soon, and so the government will have to come out of its green energy wet dream sooner than later. And even if the country managed to convert over to a green energies/hydrogen supply, it likely would be costly and extremely uncompetitive. This too would lead to a forced wake up from the green energies wet dream.

To reiterate
Germany is about half the land area of Alberta canada where I live, call it the southern half where we have much better wind resource.
Germany has 2x average load of installed renewables/wind, spread across all that territory. This generated only 40% of electricity used in 2021.
Alberta has 1.4x average load of installed reliable generation, this keeps the lights on. An extra 3GW of renewables provides show.
It does not matter if the Germans double the installed base to 4x when the wind doesn’t blow, it doesn’t blow, and in such a small area it can be calm everywhere, usually in a winter high pressure.
The 2021 Texas event hit us first, 9 days straight well below -30C with effective zero from our 3GW of installed wind.
All talk of a renewable grid is meaningless without the magic batteries, a magnitude better performance at a magnitude lower cost.

To rely on the weather to provide electricity is full of pitfalls, as Europe, California and Texas, etc., have found out.
In 2022, there was plenty of hot weather and sunshine, but little wind and rainfall in Europe
As a result, there was much solar electricity, but little wind electricity, and curtailed hydro electricity
Nuclear electricity was also reduced, because those plants need adequate cooling water to function.
Some RE folks say, oh, let’s use batteries!
This article explains the pitfalls.

Storage of hydrogen in vast quantities: just forget it ! At best in-situ production, but then there’s no advantage over natural gas. And there’s no climate problem anyway ….
I read in Die Welt that Germans are being advised to get ready for power cuts that might last longer than 72 hours, with no help avaliable from the state.
In the same paper was a lengthy article discussing fears that gas held in storage might end up being exported elsewhere in the EU – or even outside it, as the government has no means to ascertain its ownership or direct its use under EU rules. Last winter Germans were caught out because Gazprom owned significant chunks of the gas in storage and refused to release it.
Frack Germany first
