Solving a Complex Time Problem In Power BI

I was delivering some training last week for a customer in Sydney and they participants had an interesting problem where they needed to be able to report on a rolling time window. Think of it a bit like Rolling 12 Months Sales, or average weekly sales over a rolling 4 week period, but instead this problem uses a rolling time window of just a few hours. I have decided to demonstrate how to solve this problem using my own solar electricity data and build a rolling average 3 hourly kWh consumption.
