Determine the total capacity required to meet thresholds for the type of storage, following the guidance below for Peak Demand Determination.
Provide automatic load management controls for the thermal or electric storage systems.
For projects that include both an electric and thermal storage system on-site, points can be prorated to achieve the minimum required thresholds of Table 1.
PEAK DEMAND DETERMINATION
Peak demand refers to the highest average use during any one-hour period over a twelvemonth timeframe.
Peak coincident thermal demand includes the simultaneous load from heating, cooling, SWH, and process heating. It is acceptable to ignore categories with peak contribution or annual energy use less than 10% of the primary load.
To assess peak coincident thermal demand when more than one category contributes substantively to peak load:
-
Determine the category with the highest peak load (the primary load).
-
Determine the time (month, day, and hour) when this highest peak load occurs.
-
Calculate peak coincident load by adding the primary load to the simultaneous load for all other categories with substantive use.
Project space only When documenting compliance for the project space only, the peak electric demand and peak coincident thermal demand are not required to include the demand from shared systems serving the project.
Peak Electric Demand
Include all electricity used within the project boundary or used by systems exclusively serving the project space:
-
Include all project lighting and plug and process energy use.
-
Include all electricity use for HVAC and SWH systems that are wholly contained in the project boundary or exclusively serve the project space.
-
Include all electricity use for components of shared HVAC systems within the project boundary, such as VAV terminal units or fan coil units.
