DEER Load Shapes
Load shapes can be defined as the hourly pattern of loads for a given set of variables including equipment, operating characteristics, and other factors such as weather and demographics. Currently, the load shapes for the deemed measures are developed through the Database for Energy Efficient Resources (DEER) simulation models. To keep the process transparent and flexible while ensuring the measure load shapes are accurate, the CPUC has developed four sets of parameters to standardize how hourly load shapes are characterized for measures across the four roadmaps. These generalized load shape (GLS) parameters can then be used to generate an 8760 load shape for any calendar year. These parameters describe the following:
- Monthly factors for percent allocation by month (primarily applicable to seasonal loads)
- Monthly ratios of average weekend day to average weekday (most applicable to non-residential)
- Monthly ratios of peak day to average weekday (primarily weather-related)
- Monthly per-unit hourly load shapes by day type (peak day, weekday and weekend day)
(The load shapes in this context are developed based on measure case consumption load profiles. )
