[2020] Power consumption fluctuates

This would be my guess as well. If you don't have any heating plants, then electricity will be used to heat houses as temperatures go down.

Yup, temperatures will change on all maps if you have Snowfall installed. A tropical map shouldn't get cold enough to use electricity to heat up houses, and afaik there's no need to cool houses (no AC for our citizens!), which would explain the increase in consumption you see.

Do you have any factories that might halt production at times (and stop consuming electricity)? Industries DLC areas might do this when they are waiting for resources to be delivered.
