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.

It is complex, wholesale prices generally do not reflect in retail directly. even when suppliers have flexible pricing and support V2G /buying from users solar etc, there is only only some correlation not 100% pass through of rates.

There are also technical and economic reasons this may not work beyond just inelastic vendor pricing, there is cost to transmission(loss) and all the step down that has to happen before electricity is at your door, that cost will be always positive so it may not actually be net positive.

At steep enough negative pricing this could be profitable, however at that point power plants with the highest costs and easiest scale down/ shut down procedures will start acting.

Projects like the one at Dinorwig (pumped hydro-storage) are more viable solution for excess capacity.
