Renweables and nuclear don't mix well - it's too inflexible. In fact, the concept of base load generally becomes very unhelpful with an energy sector transitioning towards renewable energy (see e.g. https://citeseerx.ist.psu.edu/viewdoc/download?doi=10.1.1.18...).

Overbuilding generation capacity, either of renewables or here by peaker gas plants, rather than storage is generally recognised as the most economical way forward.
