My Utility Statement
Current level of visibility Delayed Aggregated over
Load IPS Generated using measured data from the ACme sensor deployment in Soda Hall
ACme data provides 6 months of continuous load data for individual appliances with 1 minute resolution
A Load IPS consists of a mixture of appliance types that might be found in a typical home (actual appliance chosen at random for each type)
