The European Commission proposes to take a more central role in planning new electricity grid infrastructure.
This can make a lot of sense but as my colleague @aroth.bsky.social points out transparency is crucial. Continuing to use a private & closed-source model leaves the EC open to criticism

The EC’s long-awaited "Grids Package" is finally out. Moving toward a system-oriented approach for Europe's infrastructure is the right step, but it won't work in a black box.
In my latest for @bruegel.org, I argue why transparency is important to making this effective.

⚡ Europeanised energy infrastructure planning is a good idea if done right
🤝 But will the Commission's proposal foster the trust needed to make a centralised infrastructure work?

Absolutely. Also we should pour all our energy into getting the next steps right rather than relitigating why we have not taken them already. We can do that later.
These ”none of this should’ve been a surprise and none of this is new” takes are getting a bit tired.
Yes, everyone in Europe expected Trump to be difficult and the US to withdraw from Europe in the mid- to long term. But I think it’s fair not to have expected the US to wholly turn against us.
