Unfortunately, I'm not so sure there's a quick fix for this.

Both nuclear, water and gas have the advantage that they're pretty massive and can store energy while they rotate. In the past, these systems were great for the grid because they kept on spinning and were hard to slow down. So, when there was a big load on the grid, like when an industrial plant fired up a huge device that sucked up lots of power, these giant machines took a while to slow down. That meant they could pump some extra power into the grid, at least for short periods.

The realistic option is probably to expand solar and wind power and also set up hydro pumps for storing energy. Alongside that, also invest in SMR reactors and supercapacitor to handle sudden spikes in grid demand.
