Again, even without battery storage, variations in supply from any one particular source is easily compensated for by implementing a mix of JIT technologies - hydro, wind, solar, bioenergy, and other renewables (e.g., geothermal). Uruguay, Norway, Costa Rica, Luxembourg and many other countries solved this issue years ago, as did QC, BC, MB, etc - all without having to resort to increasingly expensive, environmentally damaging nuclear projects. The only thing really standing in ON's way is politics.
