On a continent-wide grid, there will likely be some wind somewhere, and some pumped hydro ready to take advantage of the low prices.
We'll also see micro-storage developing to take advantage of electricity price variability. EVs will charge when electricity is cheapest, household water might be warmed during the day when solar energy is available, etc.
Unfortunately losing nuclear means that we lose the potential for a self-sufficient regional grid. But since the costs of losing base load power are largely offloaded from national budgets, instead showing up as new costs for consumers and companies, it's a lot easier for a politician to advocate for renewables. No need to spend taxpayer money on a project that won't be finished in the 4 years that matter to your government.
