2. Click "Calculate"
Throughout the summer of 2023 we implemented a change so the demand read on your bill will be reflective of the peak demand measured during peak hours for the billing period.  Prior to this change, the demand read reflected the highest demand for all hours, not just peak hours, but the amount can still be used for comparison purposes.
