When capacity tariffs hold back flexibility (opens the original)
Read excerpt
Electricity systems often pursue objectives that are each sensible on their own, but that can work against each other once they meet. In this post, I look at one of those conflicts.The first objective is to consume electricity when it is in surplus. On sunny and windy days, Europe increasingly produces more than it can use, and wholesale prices drop sharply, sometimes well below zero. That price is a clear signal1: using more electricity in those hours helps absorb renewable output that would ot
The evolution of the spread : 2026 update (opens the original)

This post is a continuation of previous posts I made on PICASSO (on PICASSO, and on the impact of an extreme aFRR bid). In addition, I have also updated the small app created for visualizing the CBMP p
