... and domestic tariffs that follow wholesale market pricing.

Barely any limitations on that, only thermally controlled units cycling quickly:

--- Quote from: coppice on September 29, 2023, 02:20:50 pm ---If nobody wants it, just just don't output it. Why would anyone pay a cent for the privilege of supplying useless solar power? Is that the whole purpose of negative solar tariffs? So that people ensure their output truly goes to zero when there is no market for it?

There are other market forces in place, particularly that the energy delivered by solar/wind is not always being sold at the spot price (long term energy purchases) and can be "forced" into the market to produce carbon offsets/credits/"measurable commodity units that are definitely not a tax". Pretty murky stuff when you try to pick apart all the details, but the market signals are enough to push investment in energy storage.

Politics.
There's a disconnect between customer prices (often still fixed price) and market electricity prices.
Different regions and countries evolve this very differently.
