No from my understanding that's the old thinking with power plants like nuclear and coal that cannot be easily switched on and off. Peaks in renewable generation would go into electrolysis to produce hydrogen which can "save" the surplus energy the same way we're heaping up natural gas to be used in times when the sun is not shining and when in addition there's no wind. Plus there are industrial processes that cannot (yet) be based on electric energy and need to run based on hydrogen or derivatives. In addition we can save surplus renewable energy locally, regionally and in neighbor countries (e.g. Norway with its pumped hydroelectric energy storage). This has been backed by several studies but was critically dependent on scaling up renewables massively. With the latter we failed, for political reasons.
