Cuidado porque los datos de generación proporcionados por Red Eléctrica durante el apagón son erróneos.

Makes sense, thank you.

Nuclear (violet) and interconnection (white) down, but it may be a data glitch.

I may pass by Leipzig in May or June. I'll let you know, I'd be great to see each other!

What are the best practices environmental-wise in R?

Due to their cost structure, baseload techs are not well suited to complement variable renewables. Other generation techs with lower fixed cost are better. Or storage, demand flexibility and interconnections.
comment in response to
post
Baseload techs like nuclear have high fixed and low variable costs, so they need to run at full capacity as long as possible to be competitive.

Primary energy is useful to see how much fossil fuels we burn, but 2/3 of fossil primary energy is wasted in the transformation. To compare with renewables, looking at the shares of final energy consumption is more useful. @janrosenow.bsky.social explains it here: medium.com/@jan.rosenow...

Why does the relationship break in cold climates?
comment in response to
post
It is indeed a fundamental feature of renewable vs baseload technologies. Complementary technologies (storage, demand management and interconnections) can mitigate this trade-off.

Anything that flattens the generation profile of VRE (storage, demand flexibility, interconnections) mitigates this trade-off, but the trade-off exists for any given amount of complementary technologies. Which solution is the optimal depends on their relative costs.

So what is misleading?
comment in response to
post
Baseload techs. must provide a base load not only for technical, but mainly for economic reasons (high fixed costs low variable costs).
I don't understand the second part of your post and I'll block you for being disrespectful.

Another way to see the renewable energy - nuclear trade-off: the higher the VRE penetration, the lower the residual load and thus the less need for baseload technologies.

Is there any evidence on the effect of the Cheonggyecheon restoration on traffic congestion?
Another great piece of infrastructure is the bike trails along the rivers, both in Seoul and the long-distance ones.

Hay dos cuestiones diferentes: el mercado de solo energía (o + pagos por capacidad), y tipo de fijación de precios: uniforme, pay-as-bid, etc.
La fijación de precios uniforme es la más eficiente.
El mercado de capacidad puede ser necesario, en mi opinión, si no se internalizan externalidades.

El poder de mercado lo da la concentración que permite a los grandes ofertantes manipular el precio. No hace falta "anclaje" alguno como muestra el modelo extremo con solo renovables. En la parte vertical de la oferta el precio lo marca la disposición a pagar.

Esta es la cuestión, es poder de mercado. Yo creo que con renovables variables es fácil de mitigar por tener una estructura de propiedad más descentralizada y conocer su generación potencial en todo momento con datos meteorológicos.

De todas formas el estudio es solo una aplicación numérica del peak-load pricing que existe en muchos mercados con precio unitario ("marginalista"). Mi texto favorito sobre el tema es este:

Ese estudio llega a esa conclusión, a mayor elasticidad de la demanda y almacenamiento, menores fluctuaciones de precios.
comment in response to

Lo que muestra ese modelo es que hay precios positivos sin necesidad de fósiles cuando la demanda no es inelástica y la capacidad está en su pico. Son los llamados precios de escasez. El sistema marginalista funciona en todos los mercados de commodities no es especial del eléctrico.
