This happens frequently in the UK too, if you have a compatible supplier you can set it up to charge your EV or some batteries during negative spikes. Ultimately if enough people were set up that way then prices would not get negative I suppose.

All the analysis I can find talk only about the spot price being negative.

But what matters for economics is the volume exchanged at this negative price, that is if you are a buyer with infinite capacity to absorb kWh how much money you'll make yearly?

Anyone with a good URL?

Afaik most of the energy is traded otc, spot markets are a tiny fraction of what gets delivered.

But that fraction is still interesting: since p=c must be respected, and there is always some small delta that is hard to predict and has to be covered. The spot price is not relevant to consumer prices, but it is relevant to the cost for energy providers to fine-tune their supply.
