Storage is without any doubt a major game changer in the power industry.

Ramping rates will be unlimited as battery can go from - Pmax to + Pmax within a few seconds.

Just think about the impact on our classifications of power reserves (from fast to slow). Irrelevant...

Last Sunday, German offshore wind has basically stopped producing when market prices went crazy low during the sunny afternoon.

Impressive modulation of French nuclear last week.

And quite a ramping: from 24 GW at 4 PM to 36 GW at 8 PM.

New post on solar and the increased need for flexibility.

I discuss 4 examples: increased low prices, what's happening in solar oversupply, the increased value of flex assets, and the higher prices for reserves when solar is shining.

Strange shape of the curves tomorrow in Greece.

Almost stochastic

The law of diminishing returns applies to many things including solar. Let's explore.

At first, when solar is still not dominant at any moment, you can add and add solar. You will displace something else, hopefully something that is burning like gas or coal.

Then, you start to…

Congrats Netherlands for achieving the lowest tomorrow: -200 at 1 PM.

Probably about time for reducing the net metering scheme.

Can you see the duck ?

Again, tomorrow, negative prices during solar hours + peak above 100 €/MWh.

If you have solar and no dynamic tariffs (quite a high share of people in DE), price during peak is reduced (blue) + you are paid to produce (green).

This cannot be scaled up indefinitely.

Sunday in mid May... That's where you see the most negative prices.

Here, -145 €/MWh in Switzerland. That's more than 200 € spread with the evening.

The end of intraday price variations.

Dave Jones That I did not find any big country outside Europe really acting to end fossil fuel dominance. It was a shock. It occurred ~ 18 months ago.

It is digested now. I know that no country of significant size is moving outside fossils. They just add renewables on the top of fossils.

That biomass is the largest source of renewable energy globally, accounting for 55% of renewable energy and over 6% of global energy supply.

The wow factor (to my friends at least) is even higher than the record coal of 2024 Javier Blas

The energy-only electricity markets are a great tool to select the most adequate power plants in the short-term.

Imagine if you were a monopoly that owns all power plants, how will you choose which power plant to run? Yes, you would select power plants based on their marginal…
