Electricity carbon intensity is falling - a result of over 20 years of investment in renewable generation.

However, despite this trend the carbon intensity of the electricity grid is not constant, and varies considerably by time of day and from day to day.

Many businesses are seeking to be able to either use more when carbon intensity is low, or develop technology to move demand to low carbon periods.

So when is carbon intensity lowest? Simple analysis of the last 3 years data from national grid demonstrates that on average the carbon intensity is lower overnight - when demand is low, and renewable generation that is available will continue to operate.

Good news for overnight EV charging and off-peak consumption - provided the demand shift doesn't create the requirement for fossil fuel generation to need to switch on.

Minimising carbon intensity is going to get complicated.
