This is already a reality on several grids across the world though. On weekend days with lots of sun and wind (ie low demand and high supply), prices dip below zero.
Just from an economic standpoint it can also be a valid choice to build storage next to unpredictable generating capacity, for example if you build a wind farm and want to sell during daytime (when prices are highest) as much as possible.
- ZeroGravitas 4y agoThose negative price stories have been around for years but the last time I checked, they still weren't because we had 100% renewables, which people assume to be the case. There's someone paying that negative price and it's generally fossil producers. (Technically, a 100% renewable grid could go negative I'd there were separate subsidies, but as soon as renewable goes below that level it would just be shut off rather than pay money to generate.)
