For base loading you would have to either cross your fingers on having enough solar, wind and tidal power to counteract times where each are producing low amounts of electricity. The other is geothermal, or the ill fated solar tower had a night time electricity production. Otherwise we'll just have to have big batteries or base loading nuclear power stations.

Somethings could be removed from using base loading power, such as hot water systems and electric plug in vehicles, possibly using rechargable batteries in certain items could gain cheaper electricity. Governments or companies would have to sell a several tiered electricity option where you can switch certain powerpoints to use whatever tier is needed. So some items that only require a top up of electricity could just use the cream when it is available, while your TV set can utilise the top tier.

All that happens is your powerbox has five lights. Plenty of electricity is produced, then all of them are lit up and any electricity you use is charged at a low rate. the less the electricity the dearer the electricity is and the more powerpoints stay off. So a deep freezer that is rarely opened could be on a low tier with a self switching tier if it hasn't been on in two days.

Each tier could possibly based upon 85% of electricity output. What we may find is the base loading could then be quite small as most people will only use essential services during that time.
