You need to realign what you think is reality and what reality actually is. Look at the studies again and you will see that building new renewables is cheaper in terms of increasing the total amount of exported electricity and for expanding total amount of electricity produced over the year, not to fill in during periods of high demand and low supply. Producing electricity regardless of demand is a different question that producing electricity when there is demand for it. There is also a very significant price difference between electricity bought at the cheapest possible point vs the most expensive. Producing the cheapest energy, but only during periods when the price of energy is cheapest, does not make for the cheapest energy overall.

And if you want to believe a different reality, please convince the political parties in Sweden, Denmark, Finland and so on to replace existing thermal power plants with renewable energy, and to stop construction of new ones! The green party in Sweden went into the election that we had just a few weeks ago on a energy platform that said: Thermal power plants are essential to enable renewable energy and keep prices low. Not even they believe that you can replace thermal power plants with only renewable energy and storage. Their local branch in south of Sweden is part of the coalition that approved and support the current construction of the new thermal power plant, together with the carbon capture plan.

Not that people read sources, but here is the reality check (all naturally in Swedish):
