The grid can only handle so much energy instability. So in that sense stable sources such as nuclear can be complements to unstable sources.

- pfdietz 5y agoAre you talking about short term frequency stability on the grid? This was provided by large rotating mass of conventional generators, but today that stability can be provided far better by batteries. The Hornsdale Power Reserve in Australia (that thing Elon Musk has built) made a killing off FCAS, which doesn't require more than a fraction of an hour of battery capacity. https://en.wikipedia.org/wiki/Hornsdale_Power_Reserve https://en.wikipedia.org/wiki/Hornsdale_Power_Reserve
- hokkos 5y agoYou are mixing up frequency control and inertia, Hornsdate brings FCAS but no inertia, it would need grid forming inverter.
- pfdietz 5y agoHornsdale is testing a synthetic inertia mode that will supply half the inertia needed by SA. https://hornsdalepowerreserve.com.au/learn/ https://hornsdalepowerreserve.com.au/learn/
