Consequences of the missing risk market problem for power system emissions

Are electricity markets aligned with decarbonization goals? 🔌💡
In a new paper, I and co-authors show that market frictions in long-term contracting can hinder decarbonization. We are likely under-investing in clean energy.

The funny thing about a recent FT oped on electricity prices is how the piece disqualifies itself.
Good reform requires knowing the arguments in favor of different aspects of the existing system (in this case, how spot electricity markets work).

States should make sure data centers are accompanied by more zero-fuel-cost capacity and transmission.
$16 billion. That's how much the PJM market monitor estimates that electricity ratepayers will pay via increased utility bills to subsidize interconnection of data centers owned by Big Tech. A massive give-away to some of the most profitable companies in the world.

Can confirm.
It's weird - but now in Oslo, there's so many EVs that you notice the noise and the smell from individual ICE cars, and you realise how much we've been normalising it for ever. You can smell them half a street away.
And inside parking lots are just *quiet*.

It's absolutely astonishing: In just about 13 years, Norway has skyrocketed from virtually no sales of zero-emission battery electric vehicles to nearly 100% of all new passenger car purchases.
