Counterpoint: electricity markets are terrible for reliability. Markets are great, but there are no pricing signals for reliability. You won't know that your grid will collapse at the first strong breeze, until it happens (see: Texas). Theoretically, it can work because companies might invest in reliable generation, in the hopes of getting $$$$$$$$$ when the spot price goes up through the roof. But in practice, prett…
Actually, electricity markets in Europe work just fine, and provide in fact a lot of required stability. And income events are pretty much instantanious. The only problem European markets have is way too low costs for CO2 certificates which make coal plants way to cheap. Other than that, they work just fine.
Right now it's easy to build tons of cheap low-quality wind or solar generation, but it's not economic to build any kind of storage. As a result, Europe is now dependent on natural gas and coal during the winter.
And there's nothing that can change that within the next decade.
